Use IProgressDialog to show a “native” Progress Dialog in Windows

Here's an 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.
