Hi, Tim, Your idea probably works as well, but I found another way to catch user defined message. Thanks a lot!
For the handler of the second app, win32gui.FindWindow can do this job, then win32gui.PostMessage. But for FindWindow, I can only find the specific window by its title, not by its registered class, which I posted another message. Any idea?

You said application B was also a wxPython application. Doesn't it already have a wxApp and a wxFrame main window? If you are running app.MainLoop(), that should be enough to catch messages. As long as that "OnStart" function is a member of the frame class, it should work. How are you sending the messages? How did you get the window handle of the second application? -- Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32 _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
