Printing error

rbuser

Hi,

We have the following problem.

If in some cases if the printerdriver is not installed properly, or corrupt,
and report builder tries to print to this printer, our whole application
seems to hang an this results in corrupt tables etc.
Is there a wat to just send the document to the printer and when the printer
is not ready, or the print job is not handled properly you just get a
message or just end the print job?

Something like printing in another thread, and use a timer to destroy this
thread after a long time if the printing is not done. Or put a try except
around the print command?
I don't have any experience with this. Can anyone give me some advice?

We use Delphi 6, ReportBuilder 6.02.
Our customers have different windows versions and printers.

Thanks in advance,

Wim Looman

You will be interested in our next release:) RB 7.02 will be able to print
the report in a background thread. There will be a BackgroundSettings
property you can set on the report. This will enable a checkbox on the print
dialog so that your users can choose to print in a background or not. Then
call Report.Print as you normally would. Your main application can continue
running while the background thread tries to print. If the report cannot
print due to a corrupt driver or other issue, then the thread will be freed
when it is terminated. You will also be able to cancel all background print
requests from the main thread (your app) with a cancel call on our
background print manager singleton object. There should be a demo and help
topic to describe this in more detail upon release of RB 7.02. The
background printing feature will support all output devices (except the
screen device of course).
