Re: Text window not displaying inside loop

I have a utilty I'm in the process of writing for montoring the amount
of remaining space on a number of network drives. I'm adding
functionality to loop every X-seconds then checking the figures again.
Eventually these figures will be written to a file but for now I'm
trying to display them fresh on each loop to a text box.

CString Output;
while (CountDown--) {
Output.Empty();
.
. // extract figures and format into Output
.

m_DriveList.SetWindowText (Output); // display figures
Sleep (1000); // wait a second
}

In the current configuration this should accumulate the figures and
put them in Output. I can vouch that this is being done. My problem
is that the text window won't display until the while loop is
finished. Due to an earlier glitch, when I hadn't emptied Output at
the top of the loop, I could tell that the text was being placed in
the text box because I watched the vertical scroll bar react. But it
never displayed.

Is there something I need to do to force the display? Or is this
expected behavior?
