C# equivalent of Win32 SendMessage()?

[bgowland]

I've got some code that I'm trying to translate from VB6 and raw C to a C# plug-in. The C# version uses...

private Process myProcess;

...to spawn an external application (along with the Process.StartInfo needed for exe name, window style etc.).

The app starts fine but I then need to use the equivalent of SendMessage() for IPC and I can't quite get my head around how this will work with the Process object I've created.

Any help would be gratefully received.

Cheers,
Brian

using System.Runtime.InteropServices;


[DllImport("User32.Dll")]
public static extern IntPtr PostMessage(IntPtr hWnd, int msg, int wParam, int lParam);


PostMessage(hwnd, msg, wparam, lparam);

Thanks sub - as ever, you're a star. I hadn't found that namespace yet - it looks really useful.

Cheers,
