No, I believe you need a separate .dll to get the window handle first. Although, I believe one of the window's dlls (kernel32.dll) has a function that'll let you do this. You'd need to load up the .dll in DBP, then call the correct function to get the handle.

Its not a bug, its a feature!

You can't subclass the DBPro window with DBPro - DBPro just cannot be used to create the callback function required.

Firstly, you can't get the address of a DBPro function, and secondly, DBPro uses the CDECL calling convention rather than the required STDCALL.
