DWL_MSGRESULT And a Regular Window Counter part

[SwiftX]

I noticed someone a while ago posted this same question but wasn't answered

I'm trying to make a CreateWindowEx Report List Window , in the code found like EVERYWHERE they use a custom draw and call
SetWindowLong(hwnd, DWL_MSGRESULT, (LONG)ProcessCustomDraw(lParam));

But this will only work for Dialog Boxes and after finally figuring that this is why none of my Regular CreateWindowEx work for this example with the same code , I still cant find an example that will fix this ,

Any suggestions. I modified the example on MSDN to be a Window example but no color yet , any help would be appriciated

Thanks
Swift

Maybe I misunderstood your question, but in dialog procedures
SetWindowLong(hwnd, DWL_MSGRESULT, lResult);
is equivalent to
return lResult;
in regular window procedures.
