Hi all,

We have more than a handful of Crystal Reports that we use in our app. We have just upgraded all Crystal DLLs for 9.0 and the Crystal Merge Modules. All Reports print just fine except one. When a call is made to the PrintOut() method, the following error is thrown:

"OLE IDISPATCH EXCEPTION CODE 0 FROM CRYSTAL REPORTS ACTIVE X DESIGNER: THIS FIELD NAME IS NOT KNOWN..."

We are passing in the below parameters to PrintOut, looks like this:

This.oReport.PrintOut(.F., 1, .T., , )

This only happens when we try to do a straight print. If this report is first viewed with the report viewer, then printed from there, everything is fine. We previously did not have this problem before all the updates, and we changed nothing in the report.

As I said, this is the only report that fails out of about 50 or so.

Any thoughts, ideas, ect. are greatly appreciated.

Thanks in advance,

Mike
