Here's an odd one.

Environment:
VB.NET Winform
Visual Studio 2008
.NET framework 2.0
Crystal Reports 2008
ODBC connection to SQL Server 2000 SP4

I have three reports, living in the same directory. They are essentially identical, except for the grouping. All three run successfully within Crystal reports.

From a report viewer Winform in VS, two of the three run. As I am dealing with a small data set, the reports render quickly. On the third report, There is a long pause when the report viewer form opens, then I finally get an error:


"Failed to open the connection.
Details: Database Vendor Code: 17
Failed to open the connection.
CallReportByExtension {58F5C135-7BA3-4215-898A-DADA6C7DAD9C}.rpt
Details:Database Vendor Code: 17


I was initially getting similar errors on all three reports, before changing the datasource location to my ODBC connection. I have double-checked the location, verified the database, etc.

What am I doing wrong? I can provide the VB code if requested, but since the other two reports work properly, I doubt it's code. Or I could send the .rpt files in question. I do know that I am passing the report name and path correctly to the report viewer form.

As I am about to kick my monitor through the window and become a street denizen, I would greatly appreciate any help that would be offered.

Thanks,
