Integration to Virtual Earth – Part 2 (out of 4)

If you haven’t read Part 1, you should do so before continuing here. In Part 1 we saw how to add geographical information to your customer table and how to connect to the Virtual Earth geocode web service. Now we want to put this information to play.

First of all, we all know Virtual Earth (if not – try it at http://maps.live.com). Less commonly known is it, that the map control used in maps.live.com actually is available for public usage in other web pages.

The Virtual Earth Interactive SDK

If you navigate to http://dev.live.com/virtualearth/sdk/ you will get a menu in the left side looking like this:

image

and a map looking like this:

image

(depending on where in the world you are)

Try looking at the different tabs and you can see the source code for getting a map like this – and you can select other menu items.

Try clicking at the menu item for “Show a specific map”. The map now shows the space needle in Seattle and if you click the source code tab you will see the code for creating that map:

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”&gt;
<html>
<head>
<title></title>
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″>
http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2

var map = null;
function GetMap()
{
map = new VEMap(‘myMap’);
map.LoadMap(new VELatLong(47.6, -122.33), 10 ,’h’ ,false);
}  

</head>
<body onload=”GetMap();”>

</body>
</html>

So – HTML and Javascript again. A few things which are important to know is that this line:

http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2

Imports the mapcontrol library from the Virtual Earth Web Site and allows you to use all the controls and functions exposed by this library (like a C# reference and using statement).


var map = null;
function GetMap()
{
map = new VEMap(‘myMap’);
map.LoadMap(new VELatLong(47.6, -122.33), 10 ,’h’ ,false);
}  

Is the actual code – for manipulating the map. 47.6, –122.33 should be latitude and longitude for the Space Needle, 10 is the Zoom level, ‘h’ is the style (h==hybrid) if you click the reference tab on the dev sdk window you can find the documentation to LoadMap and other stuff.

Turns out that the Space Needle is not exactly in that position – the right position would be 47.620564, -122.349577 – anyway you get the picture,

The instantiation of the Map also tells you where on the web site, the map should be placed (‘myMap’) which references a

area in the body:

 

 

This

area specifies the location, flow definition and the size of the control.

The last thing we need to know is how our function (GetMap) in Javascript is executed – and that happens as an event handler to the onload event on the body tag.

 

Note that Javascript is executed on the Client and there is no serverside code in this example.

Knowing that we can communicate with NAV Web Services from Javascript (as explained in this post) we should be able to create a site, which loads a map and displays pushpins for all our customers – more about this in a second…

Deployment

Knowing that there are a million different ways to deploy web sites I will not go into detail about how this should be done – but only explain how it can be done (aka what I did on my laptop).

What I did was to install IIS (Internet Information Server) on my laptop. After this I fired up Visual Studio, selected File –> New –> Web Site and specified that I wanted to create an Empty Web Site called http://localhost/mysite

In the empty web site I right clicked on the project and selected add new item, selected HTML page and called it default.htm:

image

C# / Visual Basic choice really didn’t matter as I wasn’t going to make any server side code.

In this default.htm I replaced the content with the following HTML

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&#8221;>

/fonta%20href=

var map = null;
function GetMap()
{
map = new VEMap(‘myMap’);
map.LoadMap(new VELatLong(47.620564, -122.349577), 16 ,’h’ ,false);
}

</body>
</html>

and when I open the site in my browser i get:

image

Voila, the Space Needle.

So far so good and if you succeeded in showing this map in a browser from your own Web Site – we know that all the basics are in place.

What’s needed in NAV

Nothing comes for free – and just because we added the latitude and longitude to the customer table doesn’t mean that we can query on them.

We need a function in NAV, exposed as a Web Service, which we can call and ask for all customers in a rectangle of the Earth. Now sceptics might say that there are no such thing as a rectangle of the earth – but programming towards the Virtual Earth API – there is. For returning the customers through Web Services I have created a XML port:

image

and the two lines of Code behind this

Customer – Export::OnAfterGetRecord()
ref.GETTABLE(“<Customer>”);
_Bookmark := FORMAT(ref.RECORDID,0,10);

for making sure that the bookmark is correctly formatted.

The function that we want to expose as a webservice looks like this:

GetCustomersWithin(latitude1 : Decimal;latitude2 : Decimal;longitude1 : Decimal;longitude2 : Decimal;VAR result : XMLport CustomerLocation)
customers.SETRANGE(Latitude, latitude1, latitude2);
customers.SETRANGE(Longitude, longitude1, longitude2);
result.SETTABLEVIEW(customers);

So this is the reason why it is good to remember to have a key on the latitude and longitude fields in the customer table.

I just added this function to the NavMaps codeunit and made sure that the other function (from post 1) is private – meaning that this function is the only function exposed and you need to expose the NavMaps codeunit as a web service in the Web Service table

image

I called it Maps – and this is used in the code below.

Combining things

In the menu you can find code for how to add shapes (pushpins and other things). You can also find code for how to subscribe to events and we are going to do this for two of the events from the mapcontrol (onendzoom and onendpan) as they change the current viewing rectangle of the control.

I will let the code speak for itself and direct attention to some of my other Javascript posts and/or information generally available on Javascript on the Internet.

image

The defaultURL variable in the start should be set to the URL of your web services listener and if you want to have more fields when you hover over a customer on the map, you will need to add these fields to the customerLocation XML port and add them to the SetDescription call in the code.

I have only tried this with the demo data – and of course you could imagine that if you have a very high number of customers the pushpin placement routine would be too slow. If this is the case, we can either limit the rectangle (if it spans too much – then ignore) or we can check the size of the returned and only place pushings for the firs xx number.

Epilog

When I said nothing comes for free, it wasn’t entirely true – this blog post is free, the usage of the information in this post is free include code snippets etc. – so some things are free:-)

I realize that this was a LOT of non-NAV code – but I do think it opens up some very compelling scenarios for integration when we combine the strength of different products using Web Services.

As always the NAV objects and the default.htm from above is available for download here.

In step 3 I will show how we can add an action to the Customer Card for showing the area map for a given customer – and you probably already know how to do this, if you have followed this post carefully.

 

Enjoy

Microsoft Windows Vista Gadget – My “Stuff”

This is my second gadget. My first gadget was the Search gadget, which you can find here.

I won’t repeat any explanation as to what a gadget is, nor will I talk about Javascript – instead I will focus upon the things, which are new in this post:

  • Returning an XMLPort from Web Services to Javascript
  • Running a Web Service method asynchronous
  • Use the same gadget for invoking three different methods
  • Poor mans error handling in Javascript

What I want to do is to create a gadget that can show My Customers, My Vendors or My Items.

image

image

image

The flyout from the gadget should be additional information about the record in the gadget, like

image

Clicking on the customer number should open the Customer Task Page and it should be easy to add additional information to this window (the things that are interesting to quickly get access to for our users).

In the Settings dialog you should be able to control things like

image

I will not discuss My Activities in this post, although it would be cool to have a Vista Gadget with My Activities (must do that some other day).

Ready? – well here we go…

The GetMyStuff Codeunit

In NAV we need to expose something, through which we can get access to My Customers, My Vendors and My Items – and the easiest thing would of course be to just expose the 3 pages: 9150 (My Customers), 9151 (My Vendors) and 9152 (My Items).

The problem with this approach is, that we need to get a bookmark back (for opening Task Pages) from the Web Service – meaning that we either create another field in these pages – or we create another Web Service Method for returning the bookmark. I really don’t want to modify base objects if I can avoid it and adding another function just multiplies the number of times we invoke Web Service method by a factor, which I am not interested in doing either.

So I am going to go with a Codeunit, 3 XML ports – and the Codeunit basically just have these three functions.

GetMyCustomers(VAR result : XMLport “My Customers”)
mycustomer.SETRANGE(“User ID”,USERID);
result.SETTABLEVIEW(mycustomer);

GetMyItems(VAR result : XMLport “My Items”)
myitem.SETRANGE(“User ID”,USERID);
result.SETTABLEVIEW(myitem);

GetMyVendors(VAR result : XMLport “My Vendors”)
myvendor.SETRANGE(“User ID”,USERID);
result.SETTABLEVIEW(myvendor);

Now returning a XMLPort (which is a NAV construct) from a Web Service sounds weird – and of course we do NOT return the XML Port object to the Web Service Consumer. What we get is the output of the XMLPort – and if you send data into the XMLPort, it is going to run the XMLPort for input.

The XMLPort for My Customers looks like:

image

and if we take a look at the WSDL for a Codeunit which returns this XMLPort, the schema for the return type very much looks like the above definition

image

and the schema for the method references this as both input and output

image

In the XMLPort properties, I have set the following properties

image

and in the Table element properties MinOccurs is set to Zero. If MinOccurs is 1 (the default), the XMLPort will return an empty My Customer if the list is empty – we do not want that.

Codebehind on the XMLPort sets the three variables _Name, _Bookmark and _Phone.

MyCustomer – Export::OnAfterGetRecord()
rec.GET(“My Customer”.”Customer No.”);
ref.GETTABLE(rec);
_Name := rec.Name;
_Phone := rec.”Phone No.”;
_Bookmark := FORMAT(ref.RECORDID,0,10);

Where rec is type Record of Customer and ref is a RecordRef.

The My Vendors and My Items XMLPorts are created following the same pattern and my gadget code will be made in a way, so that additional fields in the XMLPort will be displayed in the flyout – so you can add whatever you want to this XMLPort.

The Gadget

Again – using Javascript and instead of listing the entire Gadget Sourcecode I will describe the flow.

The main HTML body contains two areas, in which I insert the content via DHTML. These areas are called CAPTION and CONTENT.

CAPTION is for holding the top part of the gadget, where is says My Customer, My Vendor etc. and CONTENT is for holding the list of records. The reason for the caption to be dynamic is that it changes based on the selected type of course.

The first code executed in the script (except for the variable declarations) is the onreadystatechanged event handler – and note that the construct

// Microsoft suggests using onreadystatechange instead of onLoad
document.onreadystatechange = function()
{
if(document.readyState==”complete”)
{
// Initialize Settings
System.Gadget.settingsUI = “settings.html”;
        System.Gadget.onSettingsClosed = settingsClosed;

        // Initialize flyout
System.Gadget.Flyout.file = “flyout.html”;
System.Gadget.Flyout.onShow = flyoutShowing;  

        // Set the Caption of the Gadget
setCaption();

        // Initialize timer – to refresh every x seconds
setTimeout( “refresh()”, 1000 );
}
}

creates the delegate and assigns it to the event handler in one go.

In the event handler we setup the Settings dialog to use settings.html and the flyout to use flyout.html. setCaption creates a HTML string for the Caption and sets that into the CAPTION DHTML area and lastly, we setup the refresh method to be called in 1 second. This is done in order for the Gadget to be added smoothly and without any delays from connecting to Web Services etc.

The refresh function starts by adding another call to refresh delayed (depending on the RefreshInterval) and call setContent. setConent is the function, which does the actual Web Service method invoke.

// Refresh Gadget
function refresh()
{
// Initialize timer – to refresh every
setTimeout( “refresh()”, GetRefreshInterval()*1000 );

    // Set the Content of the Gadget
setContent();
}

The three functions: GetRefreshInterval(), GetType() and GetBaseURL() are only for getting variables from the settings dialog. All functions will default the settings to the default value set in the top of the Javascript section, if they are not already defined. The reason for writing the values to the settings file here is that the settings.html becomes much simpler this way.

The settingsClosed event handler is setup in the onreadystatechanged above and is called when the Settings dialog is opened (clicking on the wrench next to the gadget). This event handler will update the Caption and call refresh (in order to force a refresh now – and setup a new timeout).

// Refresh Gadget on Settings Closed
function settingsClosed(event)
{
// User hits OK on the settings page.
if (event.closeAction == event.Action.commit)
{
// Caption might have changed based on settings
setCaption();

        // Refresh content, update refresh Interval
setTimeout(“refresh()”, 1000);
}
}

The setContent function starts out by setting up some global variables based on the type shown in the gadget

// Setup variables and invoke Web Service method for getting My records
function setContent()
{
RTCpage = ”;
Type = GetType();
if (Type == ‘My Vendors’)
{
// Settings for My Vendors

        RTCpage = ’26’;
WSfunction = ‘GetMyVendors’;
XMLPortResultNS = ‘urn:microsoft-dynamics-nav/xmlports/myvendors’;
XMLPortResultNode = ‘MyVendor’;
}
else if (Type == ‘My Items’)
{
// Settings for My Items

        RTCpage = ’30’;
WSfunction = ‘GetMyItems’;
XMLPortResultNS = ‘urn:microsoft-dynamics-nav/xmlports/myitems’;
XMLPortResultNode = ‘MyItem’;
}
else if (Type == ‘My Customers’)
{
// Settings for My Customers
RTCpage = ’21’;
WSfunction = ‘GetMyCustomers’;
XMLPortResultNS = ‘urn:microsoft-dynamics-nav/xmlports/mycustomers’;
XMLPortResultNode = ‘MyCustomer’;
}
else
{
RTCpage = ”;
}
// Invoke GetMyStuff Web Service
try
{
xmlhttp = new ActiveXObject(“Msxml2.XMLHTTP.4.0”);
xmlhttp.open(“POST”, GetBaseURL()+”Codeunit/GetMyStuff”, false, null, null);
xmlhttp.setRequestHeader(“Content-Type”, “text/xml; charset=utf-8”);
xmlhttp.setRequestHeader(“SOAPAction”, “GetMyStuff”);

        // Setup event handler when readystate changes
xmlhttp.onreadystatechange = function()
{
if ((xmlhttp.readyState == 4) && (xmlhttp.Status == 200))
{
xmldoc = xmlhttp.ResponseXML;
xmldoc.setProperty(‘SelectionLanguage’, ‘XPath’);
xmldoc.setProperty(‘SelectionNamespaces’, ‘xmlns:tns=”‘+XMLPortResultNS+'”‘);
myXML = xmldoc.selectNodes(‘//tns:’+XMLPortResultNode);
updateGadget(true);
}
else
{
updateGadget(false);
}
}
xmlhttp.Send(‘<?xml version=”1.0″ encoding=”utf-8″?><soap:Envelope xmlns:soap=”
http://schemas.xmlsoap.org/soap/envelope/&#8221;><soap:Body><‘+WSfunction+’ xmlns=”urn:microsoft-dynamics-schemas/codeunit/GetMyStuff”><result></result></’+WSfunction+’></soap:Body></soap:Envelope>’);
}
catch(e)
{
// Something went wrong – display: “Service not available”, indicating that there of course are no bugs in the above code:-)
updateGadget(false);
}
}

After setting up the variables, we initialize the xmlhttp and setup a delegate function for onreadystatechange on the xmlhttp (this gets invoked when the Web Service method is done). After this we invoke Send with a SOAP document conforming to the WSDL for the Web Service.

When the onreadystatechange event handler is executed we read the XML and update the content of the Gadget. If anything goes wrong we call the updateGadget function with false – indicating that it should change the content to an error message.

The UpdateGadget builds a HTML table and inserts this table into the CONTENT area of the gadget. For every row we add a call to showflyout if the user clicks the row in order to get additional information.

// Add a row to newHTML
newHTML += ‘<tr><td height=”18″ valign=”middle” background=”Images/gadgetmiddle.png”>’;
newHTML += ‘

‘;
newHTML += ‘ ‘+myXML[o].childNodes[1].text+’
‘;
newHTML += ‘

</td></tr>’;
o++;

The showFlyout function is pretty simple

// Show flyout with additional information
function showFlyout(no)
{
System.Gadget.Flyout.show = false;
flyoutNo = no;
System.Gadget.Flyout.show = true;
}

and after this method has been called, the next thing happening is that the flyoutShowing event handler is invoked – and in this event handler we can calculate the content of the flyout and set it in the flyout.

// Flyout Showing event handler
// Calculate content of flyout
function flyoutShowing()
{
flyoutHTML = ‘<table width=”100%” border=”0″ hspace=”0″ vspace=”0″ cellpadding=”0″ cellspacing=”0″>’;
flyoutHTML += ‘<tr><td height=”31″ align=”left” valign=”middle” background=”Images/topband.png” nowrap><p><strong><font color=”#FFFFFF” size=”3″ face=”Segoe UI”>&nbsp;’+myXML[flyoutNo].childNodes[1].text+'</font></strong></p></td></tr>’;
flyoutHTML += ‘<tr><td valign=”top”><table cellspacing=”5″>’;
for(i=3; i<myXML[flyoutNo].childNodes.length; i++)
{
flyoutHTML += ‘<tr><td>’+myXML[flyoutNo].childNodes[i].nodeName+'</td><td>’;
if (i==3)
{
flyoutHTML += ‘<a href=”dynamicsnav:////runpage?page=’+RTCpage+’&bookmark=’+myXML[flyoutNo].childNodes[2].text+’&mode=view”>’+myXML[flyoutNo].childNodes[i].text+'</a>’;
}
else
{
flyoutHTML += myXML[flyoutNo].childNodes[i].text;
}
flyoutHTML += ‘</td></tr>’;
}
flyoutHTML += ‘</table></td></tr></table>’;

    obj = System.Gadget.Flyout.document.getElementById(“CONTENT”);
obj.innerHTML = flyoutHTML;
}

Really mostly string manipulation in order to create a string that looks correct. I could probably have done the same with XSLT – but this seems pretty easy. As you can see the function enumerates the content of the childNodes to myXML – and adds everything to the flyout. This means that if you add some fields to the XMLPort, then these will be included in the flyout as well.

The flyout.html only contains an empty HTML document with a CONTENT area, which is set by the code above.

Settings.html

The settings.html is really simple, with a method for reading the settings and setting them onto the form

// Initialize settings Form
document.onreadystatechange = function()
{
if(document.readyState==”complete”)
{
// Read settings and set in form
URL.value = System.Gadget.Settings.read(“URL”);
RefreshInterval.value = System.Gadget.Settings.read(“RefreshInterval”);
Type.value = System.Gadget.Settings.read(“Type”);
}
}

A method which for setting the settings back into the settings file.

// Event handler for onSettingsClosing
System.Gadget.onSettingsClosing = function(event)
{
if (event.closeAction == event.Action.commit)
{
// Write new URL into settings
System.Gadget.Settings.writeString(“URL”, URL.value);
System.Gadget.Settings.writeString(“RefreshInterval”, RefreshInterval.value);
System.Gadget.Settings.writeString(“Type”, Type.value);

        // State that it is OK to close the settings form
event.cancel = false;
}
}

and the form itself in HTML

<table width=”100%” height=”100%”>
<tr><td>
Web Service Base URL:<br>
<input type=”textbox” id=”URL” maxlength=”250″>
</td></tr>
<tr><td>
My type:<br>
<select name=”Type” size=”1″>
<option value=”My Customers”>My Customers</option>
<option value=”My Vendors”>My Vendors</option>
<option value=”My Items”>My Items</option>
</select>
</td></tr>
<tr><td>
Refresh Interval:<br>
<select name=”RefreshInterval” size=”1″>
<option value=”10″>5 seconds</option>
<option value=”30″>30 seconds</option>
<option value=”60″>1 minute</option>
<option value=”300″>5 minutes</option>
</select>
</td></tr>
</table>

I will let the code speak for itself.

If you want to see the entire thing, feel free to download it from http://www.freddy.dk/GetMyStuff.zip. the Zip file both contains the Gadget (open that and install – or rename to .zip) and a .fob file with the NAV 2009 objects. You will need to expose the GetMyStuff Codeunit as a webservice with the same name.

Search in NAV 2009 – Part 3 (out of 3)

If you haven’t read part 2 and part 1 of the Search in NAV 2009 posts, you should do so before continuing.

This is the 3rd and final part of the Search in NAV 2009 post. In this section I will show how to create a Windows Vista Gadget and have this gadget connect to NAV through Web Services and search in NAV (like the System Tray version in part 2).

We will create an installable Gadget like:

image

and when installed the user should be able to perform searches like:

image

Giving the user the opportunity to click on items and link into NAV 2009.

As you will notice the results window is different from the results window in part 2 and the main reason for this is, that I couldn’t get intra document links (that be <A HREF=”#Customers”> and <A NAME=”Customers”>) to work in a flyout. Every time you would click a link which should reposition yourself in the document – it would reload the page and leave me with a blank page.

After having struggled with this for some hours I decided that that piece was primarily done in order to help keyboard users – and since Gadgets kind of require the mouse I decided to remove the intra document links.

If anybody finds a way to do this, feel free to add a comment and make me smarter! 🙂

I actually think the sample shows that the strategy of having the Web Service just return a result set and have the consumer format this in the way that fits the consumer is the right decision.

What is a .Gadget file?

If you ever downloaded a file called Something.Gadget and opened it, you might get a warning like this

image

and if you say Install, then the Gadget gets installed – very easy indeed, but what is this?

As a hint – try to rename the file to Something.Gadget.zip – and you will see.

The file extension Gadget is known by Windows Sidebar, which will look for a Gadget.xml in the .zip file and if a correct Gadget.xml is present, it will display this installation dialog and if you select to Install, the .zip file is unpacked into a directory under

C:\Users\<username>\AppData\Local\Microsoft\Windows Sidebar\Gadgets

and add the gadget to the sidebar.

Note that the .zip file should NOT contain the outer directory – only the content.

And what is the Gadget then?

The Gadget is actually just a small html document, which can contain Javascript, VB Script code or other client side code, supported in html. The first file read by the Sidebar is the Gadget.xml file, which in my Search example looks like:

<?xml version=”1.0″ encoding=”utf-8″ ?>

<permissions>full</permissions>
<platform minPlatformVersion=”0.3″ />
</host>
</hosts>
</gadget>

So, this is where you define Name, Namespace, Version, Author, etc.  But also Icon to display in the Add Gadget and the html document to display in the sidebar (in this case gadget.html).

In my sample I will be using Javascript – not because I by any means is an expert in Javascript – but I did some Javascript coding back around year 2000 – so I guess it is time to refresh my memory. I use notepad as my editor – and the biggest problem I have run into is, that whenever I make a mistake (like misspell something btw. Javascript is case sensitive) execution of Javascript will just stop without giving any form of error. I guess there are better way to write Javascript than this – I just haven’t found it.

Gadget.html

Note, that this is not an HTML tutorial, I expect you to know the basic constructs of HTML and Javascript – you should be able to find a LOT of content around these things on the Internet.

The body section of my gadget looks like this:

<body bgcolor=”0″ leftmargin=”0″ topmargin=”0″ >
<g:background opacity=”100″></g:background>
<table width=”100%” height=”100%” border=”0″ hspace=”0″ vspace=”0″ cellpadding=”0″ cellspacing=”0″>
<tr>
<td height=”36″ align=”left” valign=”top” background=”Images/gadgettop.png” nowrap><p style=”margin-top: 10px”><strong><font color=”#FFFFFF” size=”3″ face=”Segoe UI”>&nbsp;NAV Search</font></strong></p></td>
</tr>
<tr>
<td height=”22″ valign=”middle” background=”Images/gadgetmiddle.png”>
<input type=”textbox” id=”SearchText” onFocus=”hideFlyout();”><input type=”image” src=”Images/search.png” id=”doSearch” onClick=”search();”>
</td>
</tr>
<tr>
<td height=”28″ border=”0″ background=”Images/gadgetbottom.png”>

Microsoft Dynamics NAV

</td>
</tr>
</table>
</body>

As you can see, most of this is HTML in order to make the Gadget look right. The only two Javascript methods that are called is

  • hideFlyout() – when the textbox receives focus.
  • search() – when you click the search icon (or press enter in the text box)

and of course our Gadget has references to some images from an Images folder.

The main search function looks like this

// Main search function
// search after the content in the textbox
function search()
{
// If flyout is shown, hide it
if (System.Gadget.Flyout.show)
{
hideFlyout();
}

    // Get search string
str = document.getElementById(“SearchText”).value;
if (str != “”)
{
// Perform search
result = doSearch(str);
if (result != “”)
{
// Store HTML to use when flyout pops out
newHTML = result;
// Display result in flyout
System.Gadget.Flyout.show = true;
}
}
}

System.Gadget.Flyout is part of the Gadget Framework and gives you access to set a document used for flyouts, show the flyout and hide it again.

The flyout is (as you can imagine) also just a HTML document – even though it doesn’t behave totally like a normal browser showing a HTML document – more about that later.

As you can see, the function, which will be doing the Web Service connection and the “real” search is doSearch:

// the “real” search function
function doSearch(searchstring)
{
// Get the URL for the NAV 2009 Search Codeunit
var URL = GetBaseURL() + “Codeunit/Search”;

// Create XMLHTTP and send SOAP document
xmlhttp = new ActiveXObject(“Msxml2.XMLHTTP.4.0”);
xmlhttp.open(“POST”, URL, false, null, null);
xmlhttp.setRequestHeader(“Content-Type”, “text/xml; charset=utf-8”);
xmlhttp.setRequestHeader(“SOAPAction”, “DoSearch”);
xmlhttp.Send(‘<?xml version=”1.0″ encoding=”utf-8″?><soap:Envelope xmlns:soap=”
http://schemas.xmlsoap.org/soap/envelope/”><soap:Body><DoSearch xmlns=”urn:microsoft-dynamics-schemas/codeunit/Search”><searchstring>’+searchstring+'</searchstring><result></result></DoSearch></soap:Body></soap:Envelope>’);

// Find the result in the soap result and return the rsult
xmldoc = xmlhttp.ResponseXML;
xmldoc.setProperty(‘SelectionLanguage’, ‘XPath’);
xmldoc.setProperty(‘SelectionNamespaces’, ‘xmlns:soap=”
http://schemas.xmlsoap.org/soap/envelope/” xmlns:tns=”urn:microsoft-dynamics-schemas/codeunit/Search”‘);
result = xmldoc.selectSingleNode(“/soap:Envelope/soap:Body/tns:DoSearch_Result/tns:result”).text;

// Load result into XML Document
xmldoc = new ActiveXObject(“Msxml2.DOMDocument.4.0”);
xmldoc.loadXML(result);

    // Load XSL document
xsldoc = new ActiveXObject(“Msxml2.DOMDocument.4.0”);
xsldoc.load(“SearchResultToHTML.xslt”); 

    // Transform
return xmldoc.transformNode(xsldoc);
}

Wow – a lot of code.

This is actually the only code in the Gadget connecting to Web Services – all the other code is housekeeping and has as such nothing to do with NAV 2009. Basically we just get the URL for the Web Service and use XMLHTTP to connect to the Web Service and get a SOAP response back. We use XPath to find the XML result from our codeunit. Load this into a XML Document. Load the XSLT into another XML Document and transform the XML using the XSLT – somehow similar to the way we did it in C# in part 2.

I will post other examples of Gadgets communicating with NAV Web Services, stay tuned.

The basic initialization of the gadget is done in

// Microsoft suggests using onreadystatechange instead of onLoad
document.onreadystatechange = function()
{
if(document.readyState==”complete”)
{
// Initialize Settings and Flyout
System.Gadget.settingsUI = “settings.html”;
System.Gadget.Flyout.file = “flyout.html”; 

        // Add eventhandler for Flyout onShow
System.Gadget.Flyout.onShow = flyoutShowing;  

// Write default Base URL in settings if not already done
GetBaseURL();
}
}

When setting the value of settingsUI on System.Gadget the gadget will get a small image icon when you hover over the Gadget and an Options menu item in the Context menu. Both these options will open the HTML defined in settingsUI.

There is no code in the Flyout – the only special thing is with the flyout is that it contains an IFRAME element, which loads the content.html document in order to get a scrollbar if the content of the flyout becomes too big.

The GetBaseURL function is used under startup – and when we need to connect.

// Get the Base Web Services URL
function GetBaseURL()
{
// Read the URL from settings
var URL = System.Gadget.Settings.readString(“URL”);
if (URL == “”)
{
// No settings in the settings.ini – write the default URL
URL = defaultURL;
System.Gadget.Settings.writeString(“URL”, URL);
}
// Always terminate with /
if (URL.substr(URL.length-1,1) != “/”)
{
URL = URL + “/”;
}
return URL;
}

The reason for calling the function at startup is, that we set the settings to the default URL if it isn’t already defined. It is better that the settings dialog comes up with “some” default than just a blank URL – IMO.

The settings.html contains two functions for doing the housekeeping of the settings:

// Initialize settings Form
document.onreadystatechange = function()
{
if(document.readyState==”complete”)
{
// Read settings and set in form
URL.value = System.Gadget.Settings.read(“URL”);
}
}

// Event handler for onSettingsClosing
System.Gadget.onSettingsClosing = function(event)
{
if (event.closeAction == event.Action.commit)
{
// Write new URL into settings
System.Gadget.Settings.writeString(“URL”, URL.value);

        // State that it is OK to close the settings form
event.cancel = false;
}
}

I will let the code speak for itself.

The System.Gadget.Settings read and write functions stores the settings in

C:\Users\<username>\AppData\Local\Microsoft\Windows Sidebar\settings.ini

and the settings will be stored in clear text, you will actually be able to modify this file as well.

That’s it for the NAV Search demo – I hope you like it, you can download the Gadget from http://www.freddy.dk/Search – Part 3.zip. Note that this download cannot stand alone – you need the NAV piece of this, which you can find in Part 1.

Search in NAV 2009 – Part 2 (out of 3)

If you haven’t read part 1 of the Search in NAV 2009, you should do so before continuing.

In this section we will create a small Winforms application, which uses the Web Service we just created in part 1.

Our application will be visible as a System Tray Icon, it will have a global Windows Hotkey with which we can activate search and when you activate the Search application it will popup and look like this

image

In part 3 we will create a Windows Vista Gadget version of the same app.

Visual Studio

I assume that you have worked with Visual Studio and C# before (this is not a C# tutorial – though you can of course play around with the code if you want to learn) and I will be using Visual Studio 2008 (incl. SP1) for my samples, and I won’t go into details about every function in the solution – I will however try to explain how things works and show a couple of the functions (you can download the full sample and play around with it).

In Program.cs (main program), we create an instance of the SearchForm. We do not give the form to Application.Run() – this would show the Search Form immediately and we don’t want that.

The Form has a NotifyIcon (an Icon in the System Tray) and a context menu for that Icon – all of that is setup in the Visual Studio Forms Designer and you will find event handlers for the menu items and for when the user is clicking the NotifyIcon in the code.

The application has a reference to the Search Web Service from part 1 – and currently this is pointing to

http://localhost:7047/DynamicsNAV/WS/CRONUS_International_Ltd/Codeunit/Search

If you need to change that, you do not need to recompile and change the application – you can do this by modifying the .config file, which gets deployed next to the .exe file (named the same as the .exe file with .config behind – standard .net thingy).

The NAVSearch.exe.config contains a setting for the reference, that looks like this:

<setting name=”NAVsearch_SearchReference_Search” serializeAs=”String”>
<value>
http://localhost:7047/DynamicsNAV/WS/CRONUS_International_Ltd/Codeunit/Search</value>
</setting>

The “main” code is the Event Handler for the Search Button Click event. I will let the code and the comments speak for itself.

/// <summary>
/// Event Handler for Click on the Search Button
/// </summary>
private void bSearch_Click(object sender, EventArgs e)
{
// Create the Service proxy class
SearchReference.Search searchService = new NAVsearch.SearchReference.Search();
searchService.UseDefaultCredentials = true;

    // Invoke the DoSearch method
string result = “”;
searchService.DoSearch(this.eSearch.Text.ToUpper(), ref result);

    // Did we get a result back?
if (!string.IsNullOrEmpty(result))
{
// Load the result into an XML Document
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(result);

        // Load the XSLT Transformation document
XslCompiledTransform xslTrans = new XslCompiledTransform() ;
xslTrans.Load(Path.GetDirectoryName(Application.ExecutablePath) + @”SearchResultToHTML.xslt”);

        // Perform the transformation in memory
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
xslTrans.Transform(xmlDoc, null, sw);

        // Hide the Search form
HideSearchForm();

        // Set local image path
string html = sb.ToString().Replace(“#path#”, “file://” + Path.GetDirectoryName(Application.ExecutablePath) + @””);

        // Show the Search Results form
resultsForm = SearchResultsForm.ShowHTML(html);
}
}

The result returned from WebServices was a BigText, which is a string in C# – we simply take that string and load it in an XML Document (if it isn’t empty of course).

The stylesheet needed for transforming the XML into HTML (SearchResultToHTML xslt) is also included in the project, and it also includes the images used by the HTML. In the XSLT all the images are preceded with a path identifier #path#, which we replace with the application directory in order to show the HTML proper.

I won’t go into detail about how XSLT works, there are a ton of resources on the Internet explaining this, I use it for getting from the XML I get from the Search Codeunit to the HTML – and it works for the purpose.

ShowHTML is a static function on the Search Result Form, which opens the Search Result form and displays the HTML in a webbrowser control inside the form.

/// <summary>
/// Open the search result form and show an HTML document
/// </summary>
/// <param name=”html”>HTML document to show</param>
/// <returns>The Search Result Form</returns>
public static SearchResultsForm ShowHTML(string html)
{
SearchResultsForm form = new SearchResultsForm();
form.webBrowser1.DocumentText = html;
form.Show();
form.Activate();
return form;
}

There are a number of small functions in the application to control the behavior of the application.

Windows Key + Z opens up the Search Form – is controlled by the statements

User32.RegisterHotKey(this.Handle, this.GetType().GetHashCode(), (int)Modifiers.MOD_WIN, (int)Keys.Z);

in the constructor and the following method

/// <summary>
/// Event Handler for Windows Messages
/// </summary>
protected override void WndProc(ref Message m)
{
// Only react on WM_HOTKEY
if (m.Msg == (int)Msgs.WM_HOTKEY)
{
// Show the Search Form
this.ShowSearchForm();
}
// Invoke default Message Handler
base.WndProc(ref m);
}

Of course the global hotkey is destroyed in OnClosed – when exiting the application.

When the form is deactivated – we want to hide the form, that is achieved by

/// <summary>
/// Event handler for Deactivate form
/// Hide the SearchForm when it gets deactivated
/// </summary>
private void SearchForm_Deactivate(object sender, EventArgs e)
{
HideSearchForm();
}

and whenever the form is shown, there is some housekeeping to make sure that the Search Result form is closed, it opens up in the right location and it is activated and ready to type in.

/// <summary>
/// Show the Search Form
/// </summary>
private void ShowSearchForm()
{
// If the result Form is open – close it
if (resultsForm != null)
{
resultsForm.Close();
resultsForm = null;
}
// Set the location of the searchform to the lower right corner
this.Location = new Point(System.Windows.Forms.Screen.GetWorkingArea(this).Width – this.Size.Width,
System.Windows.Forms.Screen.GetWorkingArea(this).Height – this.Size.Height);
// SearchForm is topmost
this.TopMost = true;
// Show the Search Form
this.Show();
// Activate it
this.Activate();
// Select the text in the Search TextBox and put focus in the control
this.eSearch.SelectAll();
this.eSearch.Focus();
}

The original demo scenario was a user sitting in Word, wanting to find information about an item in his NAV. The user hits Windows+Z, types in what he is looking for and hits ENTER. The Search Result Form opens with focus and the user can use TAB to select the area in which we wants to look at results or the user can move directly to the search result he is looking for and press ENTER (or use the mouse of course).

When the user presses ESC in the Task Page opened from the Search Result Form the user will return to the Search Result Form and when the user presses ESC again the user is back in the Search Form – and one more ESC will bring him back into Word and the user can continue his work.

You can download the solution for NAV Search here http://www.freddy.dk/Search – Part 2.zip. Note that this download cannot stand alone – you need the NAV piece of this, which you can find in Part 1.

Search in NAV 2009 – Part 1 (out of 3)

During the partner keynote and during a couple of the other presentations, we showed a small application, which was able to search in NAV 2009 through multiple tables, display a result set and allow people to drill into task pages in NAV 2009 from the search result window.

During the next 3 posts, I will explain how this demo is done and make it available for download. The sample comes with absolutely no warranty, but you can download it and see how things are done and reuse pieces of the sample or the full sample.

In the first part I will describe how the search functionality is done inside NAV, how to expose this as a Web Service and search from Microsoft Infopath, getting an XML result set back.

In the second part, I will describe how to create a small Windows application, which connects to the Web Service from part 1 and uses XSLT to transform the XML to a nice HTML document with links back into NAV 2009.

In the third part, I will describe how to create this as a Microsoft Windows Vista Gadget with a flyout showing the search results.

Scenario

The demo scenario goes like this:

In the tray of you Windows, there is a small Dynamics Icon

image

If you click this Icon (or use an assigned global hotkey), a small window pops up

image

The user types in what he is looking for and hit ENTER, which closes the Search Window and pops up the Search Result window:

image

Now the user can click on the links in the left hand side in order to link back into NAV, or select them with the keyboard.

The Vista Gadget which we will be completing in Part 3 looks like:

image

The only disadvantage of the Vista Gadget is, that it is doesn’t really support the keyboard very well – I like the System Tray version better:-)

But – much of this is later on – the outcome of the first part is basically the following:

image

Admitted – not very useful, but stay tuned for part 2 and 3.

Table definitions

When doing wildcard search on multiple tables, we of course need some setup tables, which will tell us which tables to search in. We also need to setup which fields in these tables we want to search in – and we need a table definition for a temporary table in which we can store the search result.

The Search Tables table defines which tables to search through.

image

Table No defines a table to search through.
Page No is the card page which should be used for showing a record from the table.
Id Field No is the field number of the ID field in the table.
Name Field No is the field number of the Name field in the table.

I have only one key in the Search Tables table – and that is Table No.

and the Search Fields table defines which fields to search for in these tables:

image

Table No is the table and Field No is a field which should be included in the search.

Also in the Search Fields we only have one key, which includes both Table No and Field No, and last but not least we need a table definition, which we use for a temporary table while doing the search.

image

for every match we find in a table, we create one record in this temporary table, where

Bookmark is the bookmark (used when launching a page in the Role Tailored Client).
Name is the name field of the record.
Table is the name of the Table in which the record was found.
Id is the id field of the record.
Page is the Page number we want to open in the Role Tailored Client for this record.

It should be clear how the outcome of this can become the XML you see in the InfoPath above – and probably also how this then transforms into the HTML in part 2 and 3.

The Search Codeunit

Disclaimer: Note, that I am not a trained C/AL developer – meaning that the following code might not be the most efficient – but it works for the purpose for which I use it. If you find things, that can be done smarter, better, faster or just things that are made stupid, let me know so that I can learn something as well.

First of all we create a Codeunit called Search and add the following code. The first section of the DoSearch method is all about searching.

The function loops through all Search Tables and for each Search Table, it loops through the Search Fields – and perform a search. For every match we create a record in the results temporary table (if it isn’t already inserted).

DoSearch(searchstring : Text[40];VAR result : BigText)
CLEAR(result);
results.DELETEALL;
IF searchtable.FIND(‘-‘) THEN
BEGIN
REPEAT
rec.OPEN(searchtable.”Table No”);
searchfield.SETRANGE(searchfield.”Table No”, searchtable.”Table No”);
IF searchfield.FIND(‘-‘) THEN
BEGIN
REPEAT
rec.RESET();
field := rec.FIELD(searchfield.”Field No”);
field.SETFILTER(‘*’ + searchstring + ‘*’);
IF rec.FIND(‘-‘) THEN
BEGIN
REPEAT
results.SETRANGE(results.Bookmark, FORMAT(rec.RECORDID,0,10));
IF NOT results.FIND(‘-‘) THEN
BEGIN
results.INIT();
results.Bookmark := FORMAT(rec.RECORDID,0,10);
results.Id := rec.FIELD(searchtable.”Id Field No”).VALUE;
results.Name := rec.FIELD(searchtable.”Name Field No”).VALUE;
results.Page := searchtable.”Page No”;
results.Table := rec.NAME;
results.INSERT();
END;
UNTIL rec.NEXT = 0;
END;
field.SETFILTER(”);
UNTIL searchfield.NEXT =0;
END;
rec.CLOSE;
searchfield.SETRANGE(searchfield.”Table No”);
UNTIL searchtable.NEXT = 0;
END;

Note, the FORMAT(recid, 0, 10) – which is the way to get a bookmark, which can be used for linking back into NAV 2009.

You probably noticed that the result is defined as a BigText and not as a XMLPort. If I was doing to use this function from C# only, I might have made it as a XMLPort – and used the strongly typed interface – but I also need to connect to this Web Service from Javascript (in part 3), so I will stick with the BigText.

That does however mean, that we manually have to build the XML document based on the temporary results table. The following code is also in the DoSearch function:

results.RESET;
results.SETCURRENTKEY(results.Table, results.Id);
IF results.FIND(‘-‘) THEN
BEGIN
CREATE(XMLDoc, false, false);
XMLDoc.async(FALSE);
TopNode := XMLDoc.createNode(1,’SEARCHRESULT’,”);
XMLDoc.appendChild(TopNode);
currentTable := ”;
REPEAT
IF results.Table <> currentTable THEN
BEGIN
currentTable := results.Table;
TableNode := XMLDoc.createNode(1,’TABLE’,”);
TableAttribute := XMLDoc.createAttribute(‘NAME’);
TableAttribute.value := currentTable;
TableNode.attributes.setNamedItem(TableAttribute);
TopNode.appendChild(TableNode);
END;
MatchNode := XMLDoc.createNode(1,’MATCH’,”);
MatchAttribute := XMLDoc.createAttribute(‘PAGE’);
MatchAttribute.value := results.Page;
MatchNode.attributes.setNamedItem(MatchAttribute);
ValueNode := XMLDoc.createNode(1,’BOOKMARK’,”);
ValueTextNode := XMLDoc.createTextNode(results.Bookmark);
ValueNode.appendChild(ValueTextNode);
MatchNode.appendChild(ValueNode);
ValueNode := XMLDoc.createNode(1,’ID’,”);
ValueTextNode := XMLDoc.createTextNode(results.Id);
ValueNode.appendChild(ValueTextNode);
MatchNode.appendChild(ValueNode);
ValueNode := XMLDoc.createNode(1,’NAME’,”);
ValueTextNode := XMLDoc.createTextNode(results.Name);
ValueNode.appendChild(ValueTextNode);
MatchNode.appendChild(ValueNode);
TableNode.appendChild(MatchNode);
UNTIL results.NEXT = 0;
result.ADDTEXT(XMLDoc.xml);
END;

Note that we build the XML in a server side COM object (XMLDoc) and after building the XML Document, I insert that in a BigText in one go.

That statement would fail in the Classic Client (because XMLDoc.xml often is larger than the allowed Text size) – but on the Service Tier, this works just fine because the ADDTEXT takes a string – and there is no size limit on that.

Populating Search Tables and Search Fields

Before we can test the Search Web Service, we need to define which fields we want the search mechanism to run on.

This can of course be done manually – or we can create a function to do this. I of course went for the second approach and created a function to populate the tables with the following data:

image image

You can see the code of that function if you download the sample, but basically it scans through metadata for all tables and searches for tables with a card form specified, which has a Search Name/Description in the table.

Now having populated the Search Tables we are ready to expose the code unit as a Web Service and test it. In the Web Service Table we need to expose the Search Codeunit:

image

having done this – you should be able to start an Internet Explorer and type in the following URL

http://localhost:7047/DynamicsNAV/WS/CRONUS_International_Ltd/Codeunit/Search

giving you the WSDL of the Web Service (given of course that your Service Tier is on localhost, DynamicsNAV is your instance name and you are using the default W1 database.

image

Testing the Web Service from Infopath

Infopath is a nice tool to test your Web Service methods and it is really pretty easy. I have added a walkthrough of how to do case you haven’t tried it before.

Start InfoPath and design a Form Template

image

Base the Form Template on a Web Service

image

Only receive data, since we are not going to alter any data in this case

image

Use the URL pointing to the Search Codeunit Web Service

image

Select the DoSearch operation

image

and give the Data Connection a name

image

Set the title and the Subtitle and drag the search string to the parameters section and the result to the data section

image

Make the result field higher, select TextBox Properties and check the Multiline checkbox, and hit Preview

image

Now the Infopath template launches and can type in cycle in the search string and hit the Run Query button. You probably need to allow Infopath to communicate to your Web Service – but after that you should get the following result

image

That’s it – if you get something similar to this, the search method works.

In part 2 we will create a small Winforms application consuming this Web Service.

You can download a zip file containing the NAV objects in a .fob file and the Infopath template here: http://www.freddy.dk/Search – Part 1.zip.

Creating and Running Hyperlinks

In the developer help for NAV 2009 (nav_adg.chm), there is a description for creating and running Hyperlinks – I will not try to repeat all the information in the documentation – so please read the documentation before reading this post.

There are however a couple of thing, which are not described in detail.

My next post is about the Search demo, which was shown at Convergence yesterday (Partner day) – I will describe how this demo is done, in a 2 step walkthrough (first is to get it to work on all operating systems and second is to make it work as a Windows Vista Gadget – stay tuned)

Bookmark

Bookmark This positions the cursor on a single record in a table.

Only automatically generated bookmarks should be used. If you enter an incorrect bookmark, you will get an error message.

dynamicsnav://localhost/DynamicsNAV/CRONUS International Ltd./runpage?page=22&bookmark=120000000089083237343

But how do you get your hands on this automatically generated bookmark?

It is actually described in another section of the documentation – Walkthrough: Creating a Link in a Report.

FORMAT(RecordRef.RECORDID,0,10)

The usage of value 10 in this expression is a RoleTailored client feature only that will format RECORDID into a text representation that is compatible with the URL handler of reports and pages. Note that this function only works if ISSERVICETIER = TRUE – if you run a code unit in the classic client, trying to use the FORMAT(xx,0,10) it will not return a bookmark for the Role Tailored Client.

Personalization ID

Personalization ID This is the unique identification used in personalization to store settings in the User Metadata table. If a personalization ID is not found, the page is launched without personalization. dynamicsnav://localhost/DynamicsNAV/CRONUS International Ltd./runpage?page=22&personalization=0000232e-0000-001a-0008-0000836bd2d2

What is this personalization ID and how do you get to that?

The Personalization ID is the way we distinguish the different views of things like the Sales Order List View. In Susans Role Center, there are 6 List Places, which all use the same underlying List Place (9305)

image

In fact, this is the reason for these List Places to be grouped together – that they have a common page number, and if we didn’t have the personalization ID, all these list places would share personalization – and in a Role Tailored User Experience, there are differences in which actions you typically would promote in a list place with shipped not invoices sales orders and a list place with ready to ship sales orders.

BTW – if you wonder where the last 4 come from – the are auto generated from the stacks in Susans Activities – and the reason for this is, that in order for navigation to work, we need to have a node in the navigation pane for every possible list place we can have in the navigation area.

The Personalization ID for these views are:

Sales Orders 0000232E-0000-0002-0008-0000836BD2D2
Shipped Not Invoiced 0000232E-0000-0007-0008-0000836BD2D2
Sales Orders – Open 00002364-0000-0006-0008-0000836BD2D2
Ready to Ship 00002364-0000-000C-0008-0000836BD2D2
Partially Shipped 00002364-0000-000B-0008-0000836BD2D2
Delayed 00002364-0000-000A-0008-0000836BD2D2

and how in earth did I find these ID´s?

Simple enogh – In a VPC, Classic Client I open the User Personalization table. Then I personalize these list places one after the other, and every time I have personalized a list place I refresh my table view and a new record pops up:

image

Sorted by Personalization ID.

For Task Pages – the personalization ID will typically just be the same as the Page ID.

But what can you use this for?

Very little as the matter of fact – if you launch a RunPage url with a list place as paramter, the list place will open as a task page, so you will need to specify which personalization you want – else you will create a personalization set with the same ID as the list place (9305 in this case). The personalizations stored under this personalization ID will never be used by the RTC (unless you launch that URL again), since we always specify the above ID’s.

So you should think that the following URL

“DynamicsNAV:////CRONUS International Ltd./RunPage?Page=9305&personalization=0000232E-0000-0007-0008-0000836BD2D2”

would open the Shipped Not Invoiced List Place in a Task Page.

That is unfortunately only partially true – you will open a Task Page with a List of Sales Orders and the Personalizations in this list are Shipped Not Invoiced – but you will NOT inherit the filters from Shipped Not Invoiced and the caption is also not what you would expect.

So now told what the personalization ID is and how to use it, but I am afraid it is only for limited usage right now.

If you want to launch a listplace you need to do like:

“DynamicsNAV:////CRONUS International Ltd./navigate?node=Home/Sales Orders/Ready to Ship”

Only problem with this URL is, that it always opens a new Client (eating one extra license).

I will investigate whether there are other ways of getting to a list place with filters and personalization – but for now, don’t specify pesonalization ID when launching pages via URL’s unless you have a good reason for doing so.
