IIUC, WndProc receives messages from the message pump. I am attempting to override the default message handler with my own. The code I posted is a contrived example. So really, I am not interested in the correctness of it, but why does the call to SetWindowLong() fail the way it does when I call it.
For a less contrived example, just google, and you will find many code samples doing almost exactly what my sample does (and ostensibly not failing). Here is a good one: http://wiki.wxpython.org/HookingTheWndProc How can that code run while passing a function reference as the last parameter, and mine fails? That is the underlying issue, not my sample code. I appreciate your bewilderment, but would be more interested in an answer to my question. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
