Infinite loop when printing report

rbuser

I've got a report with some labels on it, nothing special but once I adust
the paperformat by setting PrinterSetup.PaperHeight and
PrinterSetup.PaperWidth sometimes the report keeps generating pages. It
seems to occur mostly when printing very small reports (like labels, i tried
to print a 75 x 25 mm label) With the PassSetting set to psOnePass the
problem seems to be gone.

Is this a know problem or am i doing something wrong?And more important: Is
there a solution?

I am using ReportBuilder version 5.56 with Delphi 5

Article: TroubleShooting: Report Prints Endless Pages
------------------------------------------------------

Occasionally, we have customers state that their reports are in some
infinite state where page after empty page prints forever.

There are a few items to check when this occurs.

The TppReport.AutoStop property is the first thing to check. If this is
false when the DataPipeline property is unassigned, the endless report will
be the result. AutoStop is automatically set to True when DataPipeline is
set to nil, but it is possible to set it back to False. Check for instances
in your code where you might have created this condition.

Another thing to check is that all subreports in your report have their
DataPipeline set. When a subreport does not have its pipeline set, you will
sometimes see a condition where the first detail record prints and then you
get blank pages.

Another, non-data related cause can sometimes be your margin settings. If
you have stretching bands that need to overflow to the next page, if your
margins are too tight, sometimes the report engine will endlessly overflow
to the next page trying to fit the overflow material.

Still another cause might be having a statically positioned control, set to
ReprintOnOverFlow, in the same band with a stretching control. For instance,
if you have a memo set to stretch and in that same band, a label control set
to ReprintOnOverFlow, then on every page after the first, the memo will
begin to print after the label control. If the label is placed low enough
that the memo has no room to print, the report will forever be trying to
print the overflowing memo on the next page.

Thanks for the reply, I found the problem. When the reportheight
(headerband.height + detailband.height + footerband.height + topmargin +
bottommargin) is larger than the paperheight it will start looping when
PassSetting is set to psTwoPass.

Shouldn't there be a check on this in the reportbuilder code or is this
fixed in later versions?

Hi Mark,

Glad you found the problem. ReportBuilder 9.02 includes a feature that
checks for the condition you describe below as well as many other conditions
described in the article I sent in my earlier post.
