Forcing a form to become the focus

Ok I have what is likely a dumb question, but I want to see if there's an answer. I'm writing a program that will convert datafiles from one format to another. I have everything working, with one small problem (or two, depending on how you look at it)

When the program runs and is not waiting for the user to do something (i.e. reading in old data record, writing new data record, ect..) the system treats the program as if it were not responding. Ctl-Alt-Delete shows the program not responding, and if it looses the focus (i.e. someone opens another window that covers the program) it does not re-appear till it complete's it's job and waits for the user to confirm a message that is displayed. I tried calling Form.Repaint every loop but that did not help. It still won't be visible and still shows as not responding.

Is there a way to make sure windows knows the program IS responding when it's running? If so, what do I need to do? Will that allow the form to be re-displayed if a window is opened on top if it, and then later removed? (closed, minimized, moved, ect...)

Thanks!

Hi,
in your loop you should call Application.ProcessMessages;
this will cause your program to repaint itself etc..

Great! Thanks. That is working great. It has one or two small glitches but thats ok. I don't suppose you can help me with this one:

when I swap another window onto the app, then swap back, the animation cell I have on the form will be stuck at whatever position it was at before until the animation loop completes, then it starts over and is working. Is there a way to make the animation proceed in the background so that when the app is swapped back it does not stick the amination cell?

Thanks!

>>animation cell I have on the form

using TAnimate by any chance ;-)
i know this bug though not a workaround except maybe you wanna look at tgifimage :
http://www.melander.dk/delphi/gifimage/
you can then load animated gifs into a timage instead of using the animate comp.

It was a Tanimate. I may just kill it. I had it on there originally because I wanted people to know the program was working despite it appearing frozen. Now that it doesn't appear frozn, that kills the need for the tanimate :>
