Return value

Standard Success/Error Definitions

Return code Description
OLEUI_FALSE
 Unknown failure (unused).
OLEUI_OK
 The user pressed the OK button.
OLEUI_SUCCESS
 No error, same as OLEUI_OK.
OLEUI_CANCEL
 The user pressed the Cancel button.
 

Standard Field Validation Errors

Return code Description
OLEUI_ERR_STANDARDMIN
 Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_ERR_STRUCTURENULL
 The pointer to an OLEUIXXX structure passed into the function was NULL.
OLEUI_ERR_STRUCTUREINVALID
 Insufficient permissions for read or write access to an OLEUIXXX structure.
OLEUI_ERR_CBSTRUCTINCORRECT
 The cbstruct value is incorrect.
OLEUI_ERR_HWNDOWNERINVALID
 The hWndOwner value is invalid.
OLEUI_ERR_LPSZCAPTIONINVALID
 The lpszCaption value is invalid.
OLEUI_ERR_LPFNHOOKINVALID
 The lpfnHook value is invalid.
OLEUI_ERR_HINSTANCEINVALID
 The hInstance value is invalid.
OLEUI_ERR_LPSZTEMPLATEINVALID
 The lpszTemplate value is invalid.
OLEUI_ERR_HRESOURCEINVALID
 The hResource value is invalid.
 

Initialization Errors

Return code Description
OLEUI_ERR_FINDTEMPLATEFAILURE
 Unable to find the dialog box template.
OLEUI_ERR_LOADTEMPLATEFAILURE
 Unable to load the dialog box template.
OLEUI_ERR_DIALOGFAILURE
 Dialog box initialization failed.
OLEUI_ERR_LOCALMEMALLOC
 A call to LocalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_GLOBALMEMALLOC
 A call to GlobalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_LOADSTRING
 Unable to call LoadString to get localized resources from the library.
OLEUI_ERR_OLEMEMALLOC
 A call to the standard IMalloc allocator failed.
 

Function Specific Errors

Return code Description
OLEUI_ERR_STANDARDMAX
 Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_IOERR_SRCDATAOBJECTINVALID
 The lpSrcDataObject member of OLEUIPASTESPECIAL is invalid.
OLEUI_IOERR_ARRPASTEENTRIESINVALID
The arrPasteEntries member of OLEUIPASTESPECIAL is invalid.
OLEUI_IOERR_ARRLINKTYPESINVALID
 The arrLinkTypes member of OLEUIPASTESPECIAL is invalid.
OLEUI_PSERR_CLIPBOARDCHANGED
 The clipboard contents changed while the dialog box was displayed.
OLEUI_PSERR_GETCLIPBOAARDFAILED

The lpSrcDataObj member is incorrect.

Remarks

The design of the Paste Special dialog box assumes that if you are willing to permit a user to link to an object, you are also willing to permit the user to embed that object. For this reason, if any of the OLEUIPASTE_LINKTYPE flags associated with the OLEUIPASTEFLAG enumeration are set, then the OLEUIPASTE_PASTE flag must also be set in order for the data formats to appear in the Paste Special dialog box.

The text displayed in the Source field of the standard Paste Special dialog box, which is implemented in Oledlg32.dll, is the null-terminated string whose offset in bytes is specified in the dwSrcofCopy member of the OBJECTDESCRIPTOR structure for the object to be pasted. If an OBJECTDESCRIPTOR structure is not available for this object, the dialog box displays whatever text may be associated with CF_LINKSOURCEDESCRIPTOR. If neither structure is available, the dialog box looks for CF_FILENAME. If CF_FILENAME is not found, the dialog box displays the string "Unknown Source".

To free an HMETAFILEPICT returned from the Insert Object or Paste Special dialog box, delete the attached metafile on the handle, as follows.

void FreeHmetafilepict(HMETAFILEPICT hmfp)
{
    if (hmfp != NULL)
    {
        LPMETAFILEPICT pmfp = GlobalLock(hmfp);
 
        DeleteMetaFile(pmfp->hMF);
        GlobalUnlock(hmfp);
        GlobalFree(hmfp);
    }
    else
    {
        // Handle null pointers here.
        exit(0);
    }
}

Note

The oledlg.h header defines OLEUIPASTESPECIAL as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
