TppDBCalc, dcCount, empty dataset

rbuser

D5, RB 6.03

I have a TppDBCalc with DBCalcType = dcCount. When the dataset is empty, it
prints 1. It works fine in other cases.

Thanks,

One detail band does print if there is no data, and the DBCalc shows 1.
There is a NoDataBehaviors property on the report which gives you some more
control over what happens when there is no data. You may want to code a
TppVariable to calculate with an Inc() call. Then if the record count is
zero, then the variable's value can be set to zero.

Set the Report.NoDataBehaviors to include ndBlankReport. Then check this in
the OnCalc of the variable:

uses
ppTypes,
..
if ppdaNoRecords in ppReport1.Datapipeline.State then
Value := 0
else
Value := Value + 1;
..

Yes, I know that there are various work-arounds, but it would be nice if it
just worked properly.

Thanks, I agree that a data aware counter should display zero if there are
no records, even when one empty detail band prints. I was just trying to
get a solution to ya:)

This has been fixed for the next release.
