User32.dll help!

Question

Hi I hope this is the correct forum to post this thread? I want to know more about using the user32.dll in my programs. In particular the 'GetAsyncKeyState'. I can find resources on the web that deal with this in VB but not in C# (I don't know enough of VB to convert it to C#). Does anyone have any advice or resources I could look at? I would also like to learn anything about API programming in C#. As always thanks in advance.

That's a big help! Now I have another question: I am pretty new to programming. How can I learn more about importing dlls and which ones do what? Thanks again.

I suspect it is the code below the only thing I'm not sure about is the parameter and return type conversion but try it. You'll need to look up the virtual key constants though. -Mike using System.Runtime.InteropServices; ... [DllImport(user32.dll)] public static extern short GetAsyncKeyState(int vKey);
