Genarate a PDF from crystal report by passing parameters

Hi All,

I have a file location with 5-6 crystal reports. And I want to take those reports one by one and pass some common parameters (Ex:- data range) to each report and generate those reports in PDF format to a specific folder.

Problem in details-----

-Load Reports to the form
-select whatever the reports need
-then assign a date range
-generate reports to a specific location


Can anybody give me a hand to to do this. Atleast some sample reference links for the same.


Thanks,
Max
