Build 205 of win32gui does have PeekMessage etc so you can now write the message loop in Python should the need arise - however, the various "PumpMessages" and "PumpWaitingMessages" functions do the same thing, but are implemented in C. There are versions of these functions in win32gui and win32ui. win32ui is the MFC wrapper, and its version does do it the "MFC way", as opposed to the vanilla Windows way that win32gui exposes. Your code below looks like it is MFC based, so the win32ui versions may work better for you (eg, work correctly with the MFC idle processing). If you do truly only need VB DoEvents style processing (which is not MFC aware), win32gui.Pump(Waiting)Messages should be fine though.

Win32gui doesn't have PeekMessage. Or translate the folllowinf codes to python? DoEvents() { MSG msg; while ( ::PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE ) ) { if ( !PumpMessage( ) ) { ::PostQuitMessage( 1 ); return FALSE; } } // let MFC do its idle processing LONG lIdle = 0; while ( OnIdle(lIdle++ ) ) ; return TRUE; } } Thanks in advance, James -- http://mail.python.org/mailman/listinfo/python-list
