RAVEREPORT gerando PDF

[milton luiz]

I'm using RAVEREPORT to generate reports in PDF on unigui as extracted code in Forun

 

  UniServerModule.RvSystem.DefaultDest:= rdFile;

  UniServerModule.RvSystem.DoNativeOutput:= false;

  UniServerModule.RvSystem.RenderObject:= UniServerModule.rvRenderPDF;

  UniServerModule.RvSystem.OutputFileName:= UniServerModule.LocalCachePath+'boletim'+turma_boletim+'.pdf';

  UniServerModule.RvSystem.SystemSetups:= UniServerModule.RvSystem.SystemSetups -[ssAllowSetup];

  UniServerModule.Rv_RelBolTur.projectfile:= 'C:\Portal_Aluno_Cnslv\Rv_RelBolTur.rav';

  UniServerModule.Rv_RelBolTur.Engine:= UniServerModule.RvSystem;

  UniServerModule.Rv_RelBolTur.Execute;

  UniFrmRelBolTur.ShowModal();

 

when a User will issue a report (PDF ) in the program appears (PDF) last generated report.

It presents the latest generated in memory and not apreseta the youngest.

what can I be doing in this case ???

UniServerModule.RvSystem.OutputFileName:= UniServerModule.LocalCachePath+'boletim'+turma_boletim+'.pdf';

 

 

You need to use a unique name for each generated report. See our fast report demo to see how unique names are generated.

Have you placed your report components on ServerModule?

It is not correct place. MainModule is the right place.

[milton luiz]

when I put the reports of components of error MainModule

 

line: UniMainModule.RvSystem.OutputFileName: = UniMainModule.LocalCachePath + 'newsletter' + turma_boletim + 'pdf.';

 

error: '[DCC Error] PortalProfessor.pas (493): E2003 Undeclared identifier:' LocalCachePath '

 

can anybody help me?

Because RAVE is not thread save as far as i know we did the following:

 

1. Make a own Reportserver program  who can called from your MainModule (we did a simple vcl programm with tcp connection made with delphi standard components + Rave + Gnostice for PDF Export )

2. Call the Reportserver from Mainmodule via tcp connection (Any other Remote connection will do the job as well)

3. Wait until PDF is created and saved to disk from Reportserver ( Maybe ask Job status by polling Reportserver)

3. Grab the created PDF from the disk and present it to your customer.

As far as I know Rave Reporte is Threat safe, Because Intraweb recommend Rave for make report

Ah OK. Good to know that rave is thread save.

 

Anyway I think it is a good approach to export creating of reports to a external task.
