Print to File (via TExtraDevices AV)

rbuser

With Build 7.04 I get an AV if I print to a file (using TExtraDevices) if
the ModalCancelDialog is set at False.

The problem is in ppForms line 1346 (TppCustomCancelDialog.FormHideEvent)

Hi Peter,

We are unaware of this issue. In my quick testing with RB 7.04 for Delphi
7, I was able to successfully export to a PDF file with the ShowCancelDialog
set to False. You may try contacting Waler (support@waler.com) and see if
they know anything about this issue.

It seems that I am getting the AV when printing as well if the
ppReport.ModalCancelDialog:=False.

I have changed it to True to avoid the problem, but I thought you should
know.

Hi Peter,

Which version of Delphi are you using? Does the AV occur for every report?
If you create a minimal example consisting of a blank report on a form with
a button, do you still see the AV error?

I am using Delphi 7.

The problem only seems to occur when the "Accessing Data" dialog is
displayed (I am using ppJITs for all data access). I will try and build a
program to demonstrate the problem which I will send via email.

Hi Peter,

If you have the ShowCancelDialog property set to False, you should not be
seeing the "Accessing Data" message. Also if the AV is occuring during this
time and you are using a JITPipeline to access you data, the issue is
probably within one of the JITPipeline event handlers. Set your compiler to
stop on exceptions and point your library path to the RBuilder\Source
directory to hopefully get an idea where the problem is occuring.
