ShowCancelDialog not working?

rbuser

Hi! (RBuilder pro 7.02 and Delphi 7)

I have one BIG ppReport on my form that makes long time to print/preview, so
I'd like to show the "cancel dialog", but even if I enable it in the Object
Inspector or by code (ShowCancelDialog := true;) it does't show.

What's the problem?

Santy,

I am unable to recreate the issue on my machine. Please send a demo of the
problem to support@digital-metaphors.com and I'll take a look at it for you.

Hi!

Well, I have noticed that the problem only appears when previewing the
report (not printing)
Is it possible to show the Cancel Dialog when previewing the report?

Before printing, I show the report in a TppViewer, but some reports are too
long, so it takes long time to show. I would like to show the Cancel Dialog
before showing the report preview. Is it possible?

Thanks!

Santy,

It is not possible to cancel a request to the database once it has already
been made. The best way to control this would be to show a dialog before
the report previews that explains how long the report will take to load and
gives the user an option to partially print or fully print the report (using
autosearch fields and page limits). You should be able to create a cancel
form and use it to cancel the report generation once it has started by
having it load in the OnStartFirstPass event and close in the OnEndFirstPass
event. Be sure you have the SaveAsTemplate property set to False.
