Re: Dialog window won't update display
"Sometimes" is actually "always" - from the time that the worker thread is
started (via AfxBeginThread).
Ah, so whatever you're doing doesn't work properly at all.
The worker thread is in a do-while checking
the shared data for a command to execute. The main thread (dialog method)
sends the command and waits for completion. After that it will update the
contents of the display (static text boxes with CString variables) and
UpdateData(FALSE).
What's it do after calling UpdateData? Does it perhaps issue the next
command and then "wait"? What is it doing while it waits? i.e. what is
the wait mechanism? For a GUI to perform properly it should not really
be waiting for anything - other than it's normal message processing
loop, which is largely hidden from you in an MFC application.
The debug version does not exhibit the symptoms. Maybe that's a clue..
Yes, there's something amiss going on there then. You can debug your
release build - but it's often difficult because there's no guarantee
the debugger will show the correct values for variables.
