While opening a report: show progress bar

[DriesG]

Hello,

I have a form with a button and a progress bar.
If I click the button, a report opens. As it takes a long time to format the report, I would like the progress bar to show me the % completed.

Does anybody know how I should link the progress bar to the the formatting of the report?

I have tried to find a solution in all of the forums, but there is no exact answer.

Any help would be greatly appreciated.

Best regards,
Dries
