BUG: OLE 2.0 Does Not Support CF_OWNERDISPLAY

 Last reviewed: May 17, 1995
Article ID: Q109552
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

If an application places a data transfer object onto the clipboard and that data object enumerates CF_OWNERDISPLAY as one of the clipboard formats, the application will not receive the WM_PAINTCLIPBOARD message.

CAUSE

The WM_PAINTCLIPBOARD message is sent to the clipboard owner in order to paint the clipboard viewer window. After performing an OleSetClipboard, clipboard ownership belongs to the OLE libraries. Because no window handle information is passed with OleSetClipboard, the OLE libraries cannot forward this message to the calling application.

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 as it becomes available.
