Re: [python-win32] findwindow by its class name

Title: Re: [python-win32] findwindow by its class name

If 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?

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.
