Hi, This is probably a rather obscure question, but I don't suppose anyone here knows how to override WndProc? I am using dotnet to provide a GUI for python code and I'd like to use the win32 api WM_COPYDATA message to send simple messages between forms. I can do this in c# using this rather simple bit of code: protected override void WndProc(ref Message m) { if (m.Msg == WM_COPYDATA) { //do something with message } base.WndProc(ref m); } But despite my best efforts, I can't seem to get this to work in pythondotnet. Any ideas?
