Hallo,

Is there any functionality like the CVI function ProcessSystemEvents in the
MFC, or have I to use multi threading?

Babak,

The MFC analog to CVI ProcesSystemEvents is a message loop. Check out the MSDN article titled "Idle Loop Processing" for more information. The URL for the online MSDN is below.

It sounds like you're looking for something like VB's DoEvents. One way to do this in MFC is something like this:

void CMyClass::DoEvents()
{
MSG msg;
while (::PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE))
{
if (!::AfxGetThread()->PumpMessage())
return;
}
}
