create multiple reports at the same time

rbuser

Hi,

I need to create multiple reports at the same time.

I've tried to create a print-method in a datamodule, and call it several
times, something like that:


// Print function in datamodule
procedure Tdm1.printTest;
var
p : TppReport;
begin
p := TppReport.Create(self);

randomize;
p.Template.FileName := 'C:\Reports\Personalliste.rtm';
p.Template.LoadFromFile;

p.BackgroundPrintSettings.Enabled := True;
p.BackgroundPrintSettings.Active := True;

p.ShowPrintDialog := False;
p.ShowCancelDialog := False;

p.DeviceType := dtPDF;
p.TextFileName := 'C:\test'+IntToSTr(random(100))+'.pdf';
p.Print;

p.Free;
end;





// call print method from main form
procedure TForm1.Button1Click(Sender: TObject);
begin
dm1.printTest();
end;




This doesn't work - it just happens nothing (even no error).
Could you give me a pointer how this could be don?
Thank you very much!

Hello,

Which version of ReportBuilder and Delphi are you using?

I do not see anything wrong with your code below. If you trace into the
printTest routine, does the Report.Print call occur? Try commenting out
the BackgroundPrintSettings and see if that changes anything.

Hi Nico,

I'm using RB 12.04.

Yes, I've traced the printTest routine, and the call does occur.

When commenting out the BackgroundPrintSettings, the report is generated
as expected.

Greets,
Ben

1. You need to place the Report on the DataModule at Delphi design-time or
use the DataModule.OnCreate event to create it in code. The RB
BackgroundPrint process will make an instance of the datamodule for each
print request.

2. Make sure you a provide a thread-safe container environment in which the
report can execute. Check out the RBuilder Help topic for TppProducer
BackgrounPrintSettings for details.

3. Background print requests in processed in a queue, they are printed one
at a time. The feature is designed to generate reports in a background
thread, but not multiple reports at the same time.

Hi Nard,

Yes, when I place the Report on the DataModule it works, this way i
tried it first.
But as you mentioned in point 3, the reports are printed one at a time,
and not simultaneously. This was thre reason why I started to create the
report at runtime.

Do you have an idea how to create the reports simultaneously?
I would be very thankfull if you could give me some help on this - we
really need this feature.

Thank you very much!
Ben

RB Server Edition can be used to implement a multi-threaded server solution.
You might download that and evaluate it.

Are you looking to create 3 different reports at the same time or 3 copies
of the same report?

Is there a a sample somewhere how to accomplish this using RB Server?
Thank you!
