BUG: OLERENDER_ASIS Results in Blank Embedded Object

ID: Q110714


The information in this article applies to:
  • Microsoft OLE Libraries for Windows and Win32s, version 2.01
  • Microsoft OLE Libraries, used with:
    • Microsoft Windows NT, versions 3.5, 3.51
    • Microsoft Windows 95


SYMPTOMS

If an OLE 1.0 client application contains an embedded object and copies the object to the clipboard and an OLE 2.0 container application then performs a paste operation by creating a new embedded object based on the clipboard data by calling OleGetClipboard() and then calling OleCreateFromData(), the resulting embedded object appears blank in the container's document if the OLE 2.0 container specifies OLERENDER_ASIS as the renderOpt parameter to OleCreateFromData().


CAUSE

The OLE 1.0 compatibility layer has placed the CF_EMBEDSOURCE format onto the clipboard on behalf of the OLE 1.0 client application. This is incorrect. When copying an embedded object to the clipboard, the CF_EMBEDDEDOBJECT format should be supplied.

NOTE: The DOBJVIEW test application supplied with the OLE Software Development Kit (SDK) version 2.01 can be used to determine which clipboard formats are supplied by the clipboard data object.


RESOLUTION

An OLE 2.0 container application can avoid specifying OLERENDER_ASIS as the renderOpt parameter to OleCreateFromData() when the clipboard data object does not supply the CF_EMBEDDEDOBJECT format.


STATUS

Microsoft has confirmed this to be a problem in the products listed at the beginning of this article.
