Q121522

• Microsoft Foundation Classes (MFC), used with:
  • Microsoft Visual C++, versions 1.5, 1.51

SYMPTOMS

Any call to COleServerDoc::XDataObject::SetData will return the HRESULT corresponding to the error SCODE E_OUTOFMEMORY.

CAUSE

This is due to a missing line in the source code's TRY block that should set sc=S_OK if no exception is thrown.

RESOLUTION

Add the line sc=S_OK to the end of the TRY block in the code sample shown in the More Information section. (Currently, the sc=S_OK line appears as a comment in the sample code.) Then and recompile the MFC libraries using the supplied MAKEFILE in the \MSVC\MFC\SRC directory of your Visual C++ installation.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ 1.52 for Windows.

Sample Code

/* Compile options needed:
*/ 
STDMETHODIMP COleServerDoc::XDataObject::SetData(
     LPFORMATETC lpFormatEtc, LPSTGMEDIUM lpStgMedium, BOOL fRelease)
{
     METHOD_PROLOGUE(COleServerDoc, DataObject)
     ASSERT_VALID(pThis);

     COleServerItem* pItem;
     SCODE sc = E_OUTOFMEMORY;
     TRY
     {
          pItem = pThis->GetEmbeddedItem();
          ASSERT_VALID(pItem);
          ASSERT(pItem->IsKindOf(RUNTIME_CLASS(COleServerItem)));
          // missing sc=S_OK; here
     }
     END_TRY

     if (sc != S_OK)
          return ResultFromScode(sc);

     return pItem->GetDataObject()->SetData(lpFormatEtc,
          lpStgMedium,fRelease);
}
