TfrxDBXQuery in the AddValue method

galwacco

hi,

I'm a beginner to Fast-Reports and I'm trying to build a report that I use a "CrossTab Object".

I have a TfrxDBXQuery Called qryReport and I need to fill the CrossTab with the results of this query.

Before you guys start telling me to use a "DB-Cross Tab Oject" I will say that I have a special need to use a plain "CrossTab Object" for I'm treating the data as the report prints the cells.

I'm using the OnBeforePrint Event and this is what I'm doing:

while not qryReport.Eof do
begin
AddValue([DateToStr(qryReport.Fields[0].Value)], [qryReport.Fields[2].Value)], [qryReport.Fields[1].Value]);
qryReport.Next;
end;

At my query it returns datas from the Date, Value and Name fields which are being called with the qrytReports.Fields[POSITION].Value thing.

The problem is that I keep getting this exception:

"exception class EStringListError with message 'List out of bounds(3).'" from the
fr_iclassesrtti Unit.

I don't know exactly what I'm doing wrong, if you could help me with that I'd apreciated that a lot!!

Thanks again!!

Has Done so and all work.
You certain that , in request there is all field

procedure Cross1OnBeforePrint(Sender: TfrxComponent);
begin
ADOQuery1.First;
while not ADOQuery1.Eof do
begin
Cross1.AddValue([ADOQuery1.Fields[0].Value], [ADOQuery1.Fields[3].Value], [ADOQuery1.Fields[5].Value]);
ADOQuery1.Next;
end;
end;

Can in query no several Fields?

Den,

It was a problem in the way I was building another thing that was returning that exception, because there is no debuger in fast-reports I got kind of messed up with this thing and didn't quite know wether it was a mistake at the addValue Method or anywhere else.

Thank you for the help you extend to me always!!
