Display XML in AxSHDocVw.AxWebBrowser

In my recent blog, AxShDocVw, SHDocVw, mshtml References, I showed how to set up a VS.NET project to use the AxSHDocVw.AxWebBrowser control.I was recently asked how to display formatted XML in this control. Here's just one way. I'm sure you can find ways to improve upon it.

private void DisplayXml (

AxSHDocVw.AxWebBrowser browser,

XmlDocument document)

{

// generate a unique file name

string filnam = Environment.GetFolderPath(

Environment.SpecialFolder.InternetCache)

+ '\\' + document.GetHashCode().ToString();

// clean up just incase

if (File.Exists(filnam))

File.Delete(filnam);

// write wsdl to a temporary file

StreamWriter file = File.CreateText(filnam);

string text = document.OuterXml.Replace('utf-16','utf-8');

file.Write(text);

file.Close();

file = null;

// navigate to the temporary file

object refmissing = System.Reflection.Missing.Value;

browser.Navigate(filnam, ref refmissing,

ref refmissing, ref refmissing, ref refmissing);

}

This can be used when the control has not yet been initialized and does not yet have a body or DOM.
