TfrxReport.OnManualBuild

gpiriou

Hello,
my problem:
I am your documentation information in FR4.6 Programmer Manual and in my Delphi code I create an event
procedure TDataModule1.frxReport_TabCodeManualBuild (Page: TfrxPage);
var
...
begin
...
frxReport_TabCode.Engine.ShowBand (LDataBand);
...
end;

in this code
frxReport_TabCode.Engine.ShowBand (LDataBand);

I always have an error, it seems that I do not have access to Engine here

Thank you for your help

G'day,

Where in your code have you initialised LDataBand? And how have you done it?

Cheers, Paul

Hello,
like this:

wrote:

LDataBand := TfrxMasterData.Create(LPage);

and I also have

wrote:

LDataBand := frxReport_TabCode.FindObject('MasterData1') as TfrxMasterData;

FastReport support informed me that I could not call frxReportManualBuild (Page: TfrxPage) directly from Delphi code because otherwise frxReport.engine causes delphi execption.
I want to make a composite report with several reports of which one of them is totally written in frxReport1ManualBuild.
I block on several things:
if I call in my code delphi frxReport1ManualBuild my report is built well but I can not in this code to make a new page by Engine.newpage (exeption delphi) and therefore more support FR tell me not to make.
if i am their information i try to make this code below without success:

...... // other composite reports
frxReport1.PrepareReport(true);// this code calls frxReport1ManualBuild (Page: TfrxPage) by default
LStreamTAB.Clear;
frxReport1.SaveToStream(LStreamTAB);
LStreamTAB.Position:= 0;
frxReportcompil.LoadFromStream(LStreamTAB);
frxReportcompil.PrepareReport(false);
frxReportcompil.ShowPreparedReport;
