Show ProgressBar on Application TaskBar on Windows 7

[PPPersia]

I am looking for a way to implement a PrograssBar on Application TaskBar item on Windows 7 as you can see in Windows 7 like when copying files!
I need to do it with a few lines in Visual Basic .NET 2008.
I know there is a Windows API Code Pack by Microsoft but it's a large collection and written in C#.
Anyone knows how to do this in VB.NET without using a .dll reference?
Thanks

http://code.msdn.microsoft.com/WindowsAPICodePack is probably your best bet, it has a fair few samples of accessing the various Windows 7 apis from .Net code including the progress overlay feature.
