[python-win32] findwindow by its class name

[Mark Hammond]

Re: [python-win32] findwindow by its class nameIf all else fails, you could
create a win32gui based hidden window with a classname of your choice.
pywin32's win32gui_taskbar.py does exactly this.  You would probably need to
create this window in its own thread running a win32gui message pump, so you
would need to arrange a way to communicate with your main wx thread - but it
should be able to be made to work.

As for changing the wx classname, you would be better off asking a wx list.

Cheers,

Mark

  Thanks,
  Actually, app A is a commercial engine, which written by VC++, but we
can't change it at all.
  app B is our application, which written by wxPython, If we can't find a
way to get the classname of app B, it's no way for app A to send the message
to app B , for app A uses classname to get the handler of app B, not it's
windows caption. RegisterWindowMessage can't do this job either.

  Can we register/bind a specific classname for any wxPython application?

  James

  Application A can broadcast a private known message (using
  RegisterWindowMessage) including its own HWND; Application B handles it
and
  replies to A with its own HWND.  After that, both apps know the other's
  HWND and can post messages.
