FIX: MFC ActiveX Document Container Hangs After Deleting a Table in a Word 2000 Document (243806)

MORE INFORMATION

Steps to Reproduce Behavior

1. Build a Microsoft Visual C++ 6.0 MFC SDI application and name it SDITest. Add support for ActiveX Document containment. Accept all other wizard defaults.
2. Use the MFC ClassWizard to create class wrappers for Msword9.olb (the Word 2000 type library).
3. In CntrItem.h, add the following to the public section of CSDITestCntrItem class:

   inline LPUNKNOWN GetEmbeddedObject(){return m_lpObject;};
   					

4. Add #include "msword9.h" to the top of SDITestView.h.
5. In the TODO section of CSDITestView::InsertObject (SDITestView.cpp), add the following code:

   // TODO: re-implement selection as appropriate for your application 
   try 
   { 
     _Application pWordApp; 
     _Document pDoc;
     COleVariant covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);
     Selection pSelection; Range pRng; 
     Tables pTbls; Table pTbl; 
     Rows pRows; Row pRow; 
   
     LPDISPATCH pdisp; 
     LPUNKNOWN punk = pItem->GetEmbeddedObject(); 
   
     punk->QueryInterface(IID_IDispatch, (void**)&pdisp); 
     pDoc.AttachDispatch(pdisp); 
   
     pWordApp.AttachDispatch(pDoc.GetApplication()); 
     pSelection.AttachDispatch(pWordApp.GetSelection()); 
     pRng.AttachDispatch(pSelection.GetRange()); 
     pTbls.AttachDispatch(pSelection.GetTables()); 
   
     pdisp = pTbls.Add(pRng, 3, 2, covOptional, covOptional); 
     pTbl.AttachDispatch(pdisp); 
   
     pRows.AttachDispatch(pTbl.GetRows()); 
     long rowcount = pRows.GetCount(); 
   
     for (long i = 0 ; i <= 1; i++) 
     { 
       pRow = pRows.Item(i+1); 
       Sleep(10); 
     } 
   
   } 
   catch(...) 
   { 
     AfxMessageBox("Code error"); 
   } 
   					

6. Compile the MFC application and run it. On the Edit menu, select Insert New Object and create a new Word Document. This builds a table in the new document. Exit the MFC app and note that it exits correctly. WinWord.exe shuts down correctly and MFC quits.
7. Repeat step 6. However, before closing MFC, highlight the entire table in the Word document to select it, and then delete it (or, from the Table menu, choose Delete|Table). Close the MFC app but do not save changes.
   
   Note that the SDITest window is destroyed, SDITest disappears from the Task Bar, but MFC hangs. SDITest.exe and WinWord.exe are still running in memory. You can see them in the Windows 9x Task List by pressing the CTRL+ALT+DEL keys. They appear in the "Processes" page of Windows NT's Task Manager. The hang occurs when AfxOleTerm is called.
