Cencelling preview

carrieri63

Hi,

I've created a custom preview form using TfrxPreview component.
For some very large reports, if I close preview form before the end of loading process, I receive a List out of bounds error message. I think I need to cancel processing.

I've tried:

frxPreview.Cancel
frxReport.Engine.StopReport

but the problem persists.

Any suggestion?
Thanks,


Rafael

But I, when I use Report.Engine.StopReport method
I get EPrivilege class error (Privileged instruction)

I want to stop preparing report and show prepared pages (if they are)

I have the same problem. StopReport doesn't help and there is a bunch error windows for user while he refreshes the report. In my situation problem exists even for small 20 page report built from three fr3 files.

Try to close form in TfrxReport.OnEndDoc event

But OnEndDoc event is executed after prepare all pages !
I want to break process preparing pages !

I normally display my own progress window, with a Stop button on it:

procedure TFormRptProgress.btnStopClick(Sender: TObject);
begin
fReport.Terminated := true;
end;

fReport.Terminated := true

makes "Privileged instruction" error
