CreateWindowEx(): "Cannot find the file specified"

[matthias_k]

Ahh, thanks for the explanation.

That given, I thought it might be the best way to implement the WndProc like this:

LRESULT CALLBACK WndProc( ... )
{
    switch(message)
    {
     case WM_WHATEVER:
             // handle the message or not...
             break;
     }
     return DefWindowProc(...);
}

With this code, empty case blocks would not lead to an error, right? Because I always break to the end and return the default procedure. I have seen this approach in a sample code.

I'm currently only returning the default procedure when entering the 'default' case in the switch statement, otherwise I always return 0L. As far as I know, returning 0 tells the program that I handled a message successfully, therefor I'm a bit confused that rxbagain said CreateWindowEx failed because I always returned FALSE (0) in my Window Proc.

Can you clarify this?
