1216913 - Error Message: "...invalid class string" in Visual Foxpro 6 after updating to RDC 9

A Microsoft Visual FoxPro 6 application uses the Report Designer Component (RDC) 8 as the reporting development tool. The application runs successfully with the RDC 8, but when you update the application to use the RDC 9, the following error message appears:

"OLE error 0x800401f3 invalid class string"

The application does not run with the RDC 9 because the class string for the 'Crviewer' object needs to be updated.

Old class string:

scr8_vfp_rdc_preview.AddObject("CRViewer91","olecontrol","CRViewer.CRViewer")

New class string:

scr8_vfp_rdc_preview.AddObject("CRViewer91","olecontrol","CRViewer9.CRViewer.9.2")

====================

NOTE:

The following sample applications demonstrate the RDC Visual FoxPro
