How to get printer acknowledgement after printing

Hi All,

I need to know how to get status from printer when report is printed. Because some flags need to be updated when printing is completed.

Currently my coding like below, which causes some blank pages (because flag updated before print completed).

Coding:

crystalReportViewer.PrintReport()

updateFlag()

--------------

I am using Crystal reports for vs 2010 (13.0.10 version).

I think this can be solved if I do updateFlag() function, after printing is completed.

Appreciate if anybody can let me know how to do this with sample coding.

Thanks in advance,

Regards,

Kumara
