Handling windows-events, repainting form 1

[BasSchouten]

Hello all,

I'm looking for a Delphi 4 statement like the DoEvents statement in Visual Basic. It is used to handle all outstanding windows-events, so during long procedures you can keep the painted form up to date on the screen.

Specifically ... im setting a label.caption during an lengthy export process to inform the user of the progress, but i don't see then changes in the form.

Does anybody know the Delphi equivalent of DoEvents?

Thanks Bas Schouten

You can call a Component/Control or Forms 'update' procedure to force windows to refresh it.
have a look at 'Update' , 'Refresh' & 'Repaint' in the online help.
Also check out the function of 'application.processmessages'
this will help you keep some control during long (or possibly non terminating) loops.

Hope this helps Steve.

The Application.ProcessMessages did the trick!!

Try to put a TTimer component and combine it with a Tprogressbar, you also can incorporate the updating of the label.
