Crystal Reports XI fails with "Query Engine Error" when changing parameter values

[rharwellnc]

I'm using Crystal Reports XI, VB.Net 2003, and Oracle 9i. If I change the parameter values to a stored procedure or use the report's "Refresh" method, I get at "Query Engine Error" and the complete path to the report.

I used the code from
http://technicalsupport.businessobje...search.do?cmd=
displayKC&docType=kc&externalId=c2011787&sliceId=&dialogID=360384&stateId=1%
200%20356275
as a guide line

The report works corectly in Crystal Reports, but does not allow the
parameters to be changed when called from VB.Net. I Get the same error
message "Query Engine Exception" followed by the name of the report.

This is the code I'm using. Do you see any problems with it?

THANKS!
Rita

I've come up with a "semi-solution". The report works just fine in VB 6.0. If I use the VB 6.0 viewer and object model, the report works correctly in my VB.Net application.

HOWEVER, I really hate this "fix". I end up having two viewers in my program. A VB.Net viewer to handle the reports that do NOT access a stored procedure and a VB 6.0 viewer to handle the one report that has a stored procedure.

Any ideas will be DEEPLY appreciated.

THANKS!
