Error in RAP code

rbuser

HI!

I have a file RTM with a template creates and modifies runtime by the user
by a ppDesigner.

When I decide to print this template from another point of my project I
create all the needed component runtime and I load my template.
All works fine if I don't access the table from RAP.
I compile correctly in the designer.

The error is: "impossibile compilare il programma: DetailBeforePrint." in
italian language

// *********
a portion of code is:

dsEmissioniT := TDataSource.Create(nil);
dsEmissioniT.Name := 'dsEmissioniT';
dsEmissioniT.DataSet := tblEmissT;

ppEmissioniTestate := TppDBPipeline.Create(nil);
ppEmissioniTestate.Name := 'ppEmissioniTestate';
ppEmissioniTestate.DataSource := dsEmissioniT;
ppEmissioniTestate.RangeBegin := rbCurrentRecord;
ppEmissioniTestate.RangeEnd := reCurrentRecord;
ppEmissioniTestate.UserName := 'EmissioniTestate';

ppReport1 := TppReport.Create(nil);
ppReport1.CreateDefaultBands;

ppReport1.DataPipeline := ppEmissioniTestate;

ppReport1.DeviceType := dtPrinter;
ppReport1.Template.FileName := sPathReport + sNomeFile;
ppReport1.Template.LoadFromFile;

ppReport1.Print;

ppReport1.Free;
ppEmissioniTestate.Free;
dsEmissioniT.Free;

// *********

the code in the RAP section is:

beginif EmissioniTestate['CLASSE'] = 2 then

label7.caption := 'classe 2';

end;

Sorry I have sent early

I use RB 7.04 with DBISAM 4.05.
I have kept the same name of the component (in particular datapipe)..

Can you help me please!?!

Thanks

The report, datapipeline, etc. all need to have the same Owner. The Owner is
typically a Form/DataModule. This enables the all of the object references
to be resolved when the .rtm is loaded. (RB is using standard Delphi
streaming and that is how object references are resolved).
