Hi.

I have created a crystal report with a sub report in it. When i tried to load it into the crystalreportviewer using C#, I get the "Invalid Pointer" error at SetDatabaseLogOn method. Below is the stacktrace. Please help:

There was an parameter declaration error in one of the subreport that caused this exception. Fixed it and the code working fine.
