GetWindowRect() problem 1

[HyperEngineer]

I have the following lines in the OnCtlColor() function.

  CWnd* clientWindow = GetWindow(GW_OWNER);
  RECT MyRect;
  clientWindow->GetWindowRect(&MyRect);

The clientWindow->GetWindowRect(&MyRect) statement generates an error. It says an instruction referenced a memory location that it could not read. I tried to use memset to give the MyRect variable allocated space. I don't know what else to do. Any ideas?

If it ain't broke, it probably needs improvement.

What is clientWindow - is it anything valid?

That's what caused the error. It referred to nothing.
