The application generate several reports using the RDC of Crystal Report 8.5. All runs fine over Windows XP but when I run the application on a PC with Windows 7 the error "Server has not yet been opened" is showed at the line of code that set the source database of the report, it is at:

 

myReport.Database.AddADOCommand myCon.CN, myRs.ActiveCommand

Can someone help me with this issue?

 

Thanks in advance!
