TppCustomPreviewer

rbuser

I am attempting to create a Print Preview form based on TppCustomPreviewer.
Whenever I call the Print method of a report, the form is created but an
exception is thrown before it is displayed. I tried calling the Print
method of the Report using the standard Print Preview and it worked fine.
As another trial, I created an empty form that was based on
TppCustomPreviewer and it still produced the exception. Any idea what I am
doing wrong?

Thanks

Hello,

For future reference, please use your name when posting to these
newsgroups. Also always include the version of ReportBuilder and Delphi
you are using.

What type of exception are you receiving? If you trace into the RB
source, where is the problem occuring?

The standard method of replacing the preview is to create a custom
preview plugin. See the following article on how this can be done.

I received this same question via support@ yesterday. I recommend using the
source to the existing preview form or preview plug-in as a starting point.
I also recommend reviewing the source code to the ancestor classes. If you
are using a trial version, it does not include source code and was not
intended to be used to create custom plug-ins. If you are using a trial
version, we ask that you please purchase a license to the product. We offer
a 30-day money back guarantee on our products.
