Crystal report is not getting refreshed.

Hi,

I have crystal report in my VB.NET application, I use MS Access database to generate crystal report. My problem is crystal report is not getting refreshed when we open it multiple times with different input.

Threading.Thread.Sleep(5000)

If I sleep thread for 5 seconds before crystal report opens then it is working fine. but in this case also in very rare case crystal report is not getting refreshed.

Please provide me solution for this.

Thanks.
