BUG: OleConvertStorageToOLESTREAM() Fails When CLSID Is NULL

Last reviewed: May 17, 1995
Article ID: Q111611
The information in this article applies to:
  • Microsoft OLE Libraries for Windows and Win32s, version 2.01
  • Microsoft OLE Libraries, included with:

        - Microsoft Windows NT, versions 3.5 and 3.51
        - Microsoft Windows 95
    

SYMPTOMS

The OleConvertStorageToOLESTREAM() API (application programming interface) call is used to convert the storage of an embedded object from the OLE 2.0 storage model to the OLE 1.0 storage model. However, if the OLE 2.0 object has a CLSID of NULL, then OleConvertStorageToOLESTREAM() fails with a return code of OLE_E_CLASS.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Note that it is unusual for an embedded object to have a CLSID of NULL. However, after IOleLink::SetSourceDisplayName() has been called to change the source of an embedded link object, it is possible for that link object to have a CLSID of NULL.
