[python-win32] create user message for wxPython

[James Hu]

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? 

James

Application B must have a message loop in order to receive messages.  
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?
