I have made a simple MFC(dialog based) program in which the dialog box has
a CEdit box i have defined a DoDataExchange
so my problem is whenever I do something like this
for(i=0;;i++)
{
e=i;
UpdateData(false);
}
where "e" is associated with the edit box
The values as they should be instantaneously displayed in the box the moment
they change, but nothing happens and dialog box freezes.
but if I call a MessageBox("fh"); after UpDateData(false) then the message
box is displayed and the value change is also displayed ,but I want it
without this message box....plz help me

nexolite:

I would use SetWindowText() here. Also, once your loop starts there is nothing
to stop it, and you will have to kill the application. Better to use a timer.

You might be able to get away with calling UpdateWindow() on the edit control
(together with a Sleep()), but you would be much better to use a timer instead
of your loop.
