That solves the problem of the undefined identifier. I'm assuming that's the value assigned in the lib?

I'm still experiencing the error, but now that I at least have the correct value for GWL_USERDATA it's probably an error in my code somewhere. Maybe I need to use CreateWindowEx instead or something. If I solve it I'll post just to close this thread :)
