win32 api

Can you call the win32 api in C# like vb6? If so is there a tool like pat or jk's api spy, or something similar? Are there any tutorials for win32 api programming? or books?

What I would like to do is like push a button on another application or take information from a listbox on another application.

Thanks for the info!

I really like www.pinvoke.net they contain some good tutorials, plus they have an addon for Visual Studio.

Here is an example of using the FindWindow API in C#...
pinvoke.net: FindWindow (user32)

<Edit>
Also are you sure its a listbox and not a listview?
