Well, I was looking through some more of my prototypes that I’ve written and I came across the following example of how to use the IProgressDialog Win32 Interface to harness the power of the Built-in Progress Dialog in Windows within your own .NET applications. I have test this on WIndows 7, but it should work as expected on Windows XP and Vista. The MSDN Documentation for IProgressDialog says it’s minimum supported operating systems are Windows 2000 and Windows XP. The full source code for this example is listed below. Just copy from this post and paste it within your app to test.
