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.
