[GD-Windows] Updates in a modal dialog loop

[Brian H. <ho...@bo...>]

I have a dialog box (MFC) that does processing and that periodically 
needs to pump the message loop so that paints, etc. can propagate.  In 
other words.  What is the right way to pump the loop?  I see that 
there's RunModalLoop(), EndModalLoop(), and ContinueModal(), but I 
don't see examples of how they're used and I'm not even sure if 
they're the right direction.

In a regular windows loop I'd do some work then call 
Get/Translate/DispatchMessage() periodically to get a similar effect, 
but there doesn't seem to be a corresponding facility here.

Thanks,

Brian
