A Microsoft Visual Studio 2005 .NET application is being developed using the Crystal Reports XI Release 2 .NET SDK as the reporting development tool. When attempting to create a member variable for the ActiveX viewer, the following error message appears:

"Line: 1198 - Error: The Extender Provider failed to return an Extender for this object."

Steps to reproduce:

1. Start Visual Studio .NET 2005.

3. In the Project Types dialog box, expand Visual C++ Projects and select MFC.

4. In the Templates dialog box, select MFC Application.

5. Provide a name for the application and click OK. The MFC Application Wizard appears.

7. Select ICrystalReportViewer11 from the Interfaces list and move to the Templates list. This will generate a class with the name CCrystalReportViewer11.

8. Click Finish.

9. Right-click the ActiveX viewer control and click Add Variable. When the error appears, click No.

10. Choose CCrystalReportViewer11.h as the .h file and CCrystalReportViewer11.ccp as the .CPP file.
