Re: [GD-Windows] Updates in a modal dialog loop

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

Doh, left out some important information.

First, the dialog is modal.  Second, it actually does its work in a 
separate thread along the lines of:

while ( !done )
{
   update_some_stuff();
   update_controls_to_reflect_changes();
}

The problem (I think) is that the updated stuff is happening in that 
separate thread, in parallel to whatever stuff the regular Windows/MFC 
dialog modal loop is doing.  It checks for cancellation periodically 
(assume that I haven't screwed up the app's synchronization with 
itself, but since I'm unsure what the sync rules are for MFC, heaven 
help me).

I'm hesitant to use a timer for this, since it's one of those "run as 
fast as you can" type things that might under/overrun a timer's 
interval.
