Adding a summary to an exisiting report

edited October 2003 in General
I have inherited a program that uses multiple report engines, 'ugh'. But my
question involves adding a summary to just one of them.
I am using the ppSummaryBand1BeforeGenerate to run a procedure that
populates a Memo box as such:


procedure TForm_StudyReport.ppSummaryBand1BeforeGenerate(Sender: TObject);
begin
PopulateLegend;
end;

procedure TForm_StudyReport.PopulateLegend;
var
IntList :variant;
begin
IntList := FPerslIDAccum.CommaText;
If IntList <> '' then
Begin
ppLegendTitle.Visible := true;
ppLegend.visible := true;
with QueryX do
Begin
SQL.Add('select LAST_NAME, FIRST_NAME, INITIALS ');
SQL.Add('from personnel ');
SQL.Add('where Personnel_id in ('+IntList+')');
Open;

While not Eof do
begin
ppLegend.Lines.Add(Fields[2].AsString +#9+
Fields[0].AsString +', '+ Fields[1].AsString );
Next;
end;
Close;
SQL.Clear;
End; //with
End;
end;


The TStringlist is a Sorted, IgnoreDup list.

My problem is that the event ppSummaryBand1BeforeGenerate seems to be firing
for every element in the Detail section!? The Help states that this is just
to happen once per report with one summary band. Can you help me.

I have recently upgraded from 5.54 to 6.0
TIA

    Hello,

    For future reference, we prefer that you use your real name when asking
    questions on this newsgroup.

    It is never a good idea to manipulate data during report generation. This
    is not what the Report Engine was designed to handle. I would recommend
    creating another dataset outside the report using the SQL you mentioned in
    your previous post. Then place a TppSubreport inside the summary band and
    connect it to your new dataset. The subreport will then traverse your data
    automatically without the need for a while loop, or any other code.

    If you are planning on spending some time with ReportBuilder, I would also
    recommend going over the ReportBuilder Developer's guide when you get a
    chance. This is an excellent resource and tutorial that enables a user to
    hit the ground running when starting developing with ReportBuilder. A copy
    of the Developer's guide can be found in your \RBuilder\Developer's
    Guide\... directory.
