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,
are implemented in C. There are versions of these functions in win32gui
win32ui. win32ui is the MFC wrapper, and its version does do it the
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
truly only need VB DoEvents style processing (which is not MFC aware),
win32gui.Pump(Waiting)Messages should be fine though.

Hi, all gurus,
I need to simulate DoEvents in VB by python/wxPython,
My application needs to capture live image in a loop until one specific
Multi-thread is also not very good solution, for there are big number of
data to exchange between the two threads.
Win32gui doesn't have PeekMessage.
Or translate the folllowinf codes to python?
while ( ::PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE ) )
if ( !PumpMessage( ) )
::PostQuitMessage( 1 );
// let MFC do its idle processing
LONG lIdle = 0;
while ( OnIdle(lIdle++ ) )
Thanks in advance,
