Delphi 7 :: Rave Report - Several Reports Print in ONE spool JOB

Zones: Delphi Printing, Delphi Programming, Delphi Components

Tags: rave, delphi, report

Dear Experts,

I am using Delphi 7 and Rave Reports.
I have a procedure which loops through a dataset and according to my parameters
prints reports.
How can I change my code to rather loop through the dataset and add all the reports, somewhere???, and after the loop I would like to do ONE print execute which will then print all added reports in one spool job.

I have looked at the nevrona tip at: http://www.nevrona.com/Default.aspx?tabid=117
but it is not clear enough to me. Because for each report I am setting some params as well.

Anyone that can please explain this to me in detail?

Please see my current code attached....

Thanks in advance.

Normally when I get blank pages the dataset is returning no records... That can be due to not setting parameters or other issues. It depends on what type of datasets you are using in Rave too. First just create 3 form style reports that require no data. All you have to do is put a shape, text box, etc on the report and save it. Then, run your code calling those reports (so they print in one job). This should work with no problems and indicate that there is nothing wrong with your code. You then need to figure out why your report has no records.
