Window Handle's

[Sardith]

The C++ code for getting the handle works. It's getting a processes sub window handle.

Spy++

FindWindow("Valve001",NULL);

When I try WinGetHandle("Valve001"), it' doesn't recieve a handle, for some reason. I've never delt with a processes sub processes or window. Im not really sure what to call it. I've used Spy++ to verify that the window exist, and that it's a "sub process within a larger process" HL2.exe -> Valve001

If any one could help me that would be great.

Updated things, and I hope it's more clear.
