You have a default Microsoft Foundation Class (MFC) ActiveX control that is built with Microsoft Visual C++ .NET 2003. You drop this form in Design mode on a Microsoft Visual Fox Pro 6.0 running form on a computer that is running Microsoft Windows 98. When you save the form, you receive the following error message:
OLE Error code 0x80004005: Unspecified error.
You do not receive this error message with MFC ActiveX controls that are built with Microsoft Visual C++ .NET 2002 or with earlier versions of Microsoft Visual C++.

When you save a Visual Fox Pro form with an MFC ActiveX control, the IPersistStreamInit::Save interface method of the control is called. This eventually calls the AfxFullPath() function with name of the stream. In Visual C++ .NET 2002, and in earlier versions of Visual C++, this call failed on computers that were running Microsoft Windows 98. However, the failure was ignored. In Visual C++ .NET 2003, an exception is thrown. Visual Fox Pro captures the exception and displays it as the error message that is mentioned in the "Symptoms" section.
