Hi!

I used the following code. By the way the call in my code GetTempFile calls the Windows API GetTempFileName.

rptReport.Reset;
rptReport.Template.FileName := fullfilename;
rptReport.Template.LoadFromFile;
rptReport.Language := lgDutch;
rptReport.LanguageID := 'Dutch (Netherlands)';
rptReport.DataPipeline := pipREPORTLINES;
rptReport.PDFSettings.EncryptSettings.Enabled := false; // Nieuw V9.10
rptReport.PDFSettings.OpenPDFFile := false; // Nieuw V9.10
rptReport.OutlineSettings.CreateNode := false; // Nieuw V9.10
rptReport.OutlineSettings.CreatePageNodes := false; // Nieuw V9.10
rptReport.OutlineSettings.Enabled := false; // Nieuw V9.10
rptReport.OutlineSettings.Visible := false; // Nieuw V9.10
rptReport.TextFileName := '($MyDocuments)\Report.pdf'; // Nieuw V9.10
rptReport.Template.DatabaseSettings.DataPipeline := pipREPORTLINES; // Nieuw V9.10
rptReport.SaveAsTemplate := false; // Nieuwe V9.10
rptReport.AllowPrintToFile := false; // Nieuwe V9.10
rptReport.AllowPrintToArchive := false; // Nieuwe V9.10
rptReport.ResetDevices;
rptReport.DeviceType := dtScreen; // Nieuw V9.10
rptReport.Device := dvScreen;
rptReport.PassSetting := psTwoPass;
rptReport.AutoStop := false;
rptReport.CacheManager.CachePath := dtmBoot.GetTempFile;
rptReport.ArchiveFileName := dtmBoot.GetTempFile;


Should I use some method for caching to memory instead of disk? Or else? By the way, I don't need caching. This property 'CachePages' is turned OFF in the component. PLEASE HELP!!
