How to generate Multiple PDF files ?

Dear Experts ,

I need to generate multiple PDF on single button click . I am passing Account Code as parameter , for 1 account code we have multiple sub ledger .

I need to group by Account code wise and sub ledger wise,so I am using Group expert formula and I selected new page after 1 visible group .

If I have 10 sub ledger , I have 10 pages of record in single PDF .

Instead of this I need to generate 10 page as separate PDF (like 10 pop up ) , is it possible to generate using sap crystal report and Visual studio 2010 vb.net?

If it is possible I need to send sub ledger wise mail to customer .
