Hi Arif,

------------------------------------------------------
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.

My Code is.

dmReports.tVoucher.close;
dmReports.tVoucher.Open;
dmReports.tVoucher.Filtered := False;
if dmReports = nil then
Application.CreateForm(TdmReports, dmReports);
dmReports.tVoucher.Filter := 'TrVoucherNo = '+eVoucherNo.Text+' AND
TrType = '''+VT+'''';
dmReports.tVoucher.Filtered := True;
if Sender = nil then
begin
dmReports.RBVoucher.DeviceType := 'Printer';
dmReports.RBVoucher.showprintdialog := false;
end
else
begin
dmReports.RBVoucher.DeviceType := 'Screen';
dmReports.RBVoucher.showprintdialog := true;
end;
dmReports.RBVoucher.Print;
Loading := True;
dmReports.tvOUCHER.Filtered := False;

can you tell in which part i should set the autostop property. by default
autostop property is to false;

Arif,

If your report and subreports are successfully connected to their specific
datapipelines, the AutoStop property is probably not your problem. If you
would like to set it, you will need to do so before printing the report
(i.e. either inside the Report.BeforePrint, or before you call
Report.Print).

You need to check that you do not have things like the same datapipeline
connected to the master report and subreports. Also check that you are able
to fit all your report components inside the defined margins.

hi,
actually i am new to report builder. can you help me to follow all the
steps which you told me step by step like how to check same datapipeline

and how can i check that i am inside defined margins
thanks

Hi Arif,

Welcome to ReportBuilder .

You can check what datasource (datapipline) each report/subreport is
connected to by selecting the Report | Data... main menu option from the
report designer window. If the AutoStop property is set to False and your
report does not have a pipeline assigned, you will get the endless pages
effect. The AutoStop property is published so it is available in the Delphi
Object Inspector when you click on the report object.

Check your margin settings by going to the File | Page Setup in the main
menu. Then be sure none of your report objects exist beyond these margins.
If they do, the report engine will try to break to a new page thinking that
the current object will not fit on the current page. Unfortunately this
will happen on every page there after causeing endless pages.

Hi Arif,

Please send an example of this behavior to support@digital-metaphors.com in
.zip format and I'll take a look at it for you.

Arif,

For future reference, please do not attach binary files to your newsgroup
posts. Please send all attachments to support@digital-metaphors.com. I'm
going to need a little more background information on the example you sent
me. You have somewhere around 17 report objects on your data module. Which
report is giving you the error? Have you considered using Report Templates
rather than all the report objects? This would allow you to keep all your
reports and data access information in separate compact files while only
using one report object. See our web site or consult the ReportBuilder
Developer's guide for "ReportBuilder Pro" for more information on this.
