Thanks all.
As U can C I M a newbie ...
But I tried using the timer, the problem was that the dialog did not get any
message, including WM_TIMER, so I couldn't use this method.
I'd really appreciate any help, but I think it is not a trivial task to make
both the MDI and the progress bar dialog repainted parallely.
It took me some time to figure that solution (it is based on a solution for
the same problem, which I got in this news group).

A sample will be great help, also any kinda help,
Thanks again,
Janiv.
