Displaying XML in the .NET WebBrowser Control

October 17, 2006

Internet Explorer displays XML in a pretty decent manner. Today I figured I would use the same engine to display XML in a .NET 2.0 application. So I dropped a WebBrowser control on to a form, and assigned my XML string to the DocumentText property. Voila? Of course not.

After some digging, I found that IE uses a built-in XSLT-transform to present XML as HTML in the browser. The stylesheet in question is available from the following uri in IE: res://msxml.dll/defaultss.xsl. Ok then, so one can just save this string, and use it in .NET? Not quite. As it turns out, the XSL that IE uses is not compatible with .NET’s XslCompiledTransform class. D’oh!

After some more digging, it turns out that Steve Muench has done the conversion to the XSLT 1.0 REC that .NET requires. Thanks, man! The file can be downloaded here.

I added the following code to my WebBrowser base class, to allow developers to display XML by setting a property:

public XmlDocument DocumentXml
{
set
{
Stream s = <defaultss.xsl from embedded resource file>

XmlReader
xr = XmlReader.Create(s);
XslCompiledTransform xct = new XslCompiledTransform();

xct.Load(xr);

StringBuilder
sb = new StringBuilder();
XmlWriter xw = XmlWriter.Create(sb);
xct.Transform(value, xw);

this.DocumentText = sb.ToString();
}
}

Turned out kind of neat in the end, huh?

O’ project, where art thou?

September 14, 2006

If you have been using Visual Studio 2005 and data adapters in the designer, I bet the following error message have caused you quite a lot of grief:

“Could not retrieve the current project”

Some days ago, I found a solution that seems to work every time: select the data adapter in the designer, bring up its property page, edit the connection string, and then change it back again, and voila – the missing project is back! I suspect that it is not the connection string itself that does the magic, but rather that I am configuring some other component that probably is in a more “stable” state, and hence is able to restore whatever link that has been lost to the current project.

I – conflict resolver

July 25, 2006

At times, Visual SourceSafe finds it best to upon checkin ask me: “have any conflicts in [file] been properly resolved?”. Now, how the #¤! am I supposed to know that, Mr. VSS? Oh, the horror!

 

Tempting as it is, pressing “Help” won’t help you out either…
