 	 * 2) ::CreateDialogIndirect() did create a window and then send the appropiate 
 	 *    creation messages (ie. WM_CREATE).  However, the user handled WM_CREATE and 
 	 *    returned -1.  This causes windows to send WM_DESTROY and WM_NCDESTROY to the
 	 *    newly created window.  Since WM_NCDESTROY has been sent, the destructor of this
 	 *    CWnd object has been called.  And ::CreateDialogIndirect() returns NULL.
 	 * 3) ::CreateDialogIndirect() did NOT create the window (ie. due to error in template)
 	 *    and returns NULL. 
 	 *
 	 * (Note: In 3, this object is still valid; whereas in 2, this object has been deleted).
 	 *
 	 * Adding to the complexity, this function needs to do 2 memory clean up (call 
 	 * pOccManager->PostCreateDialog() and delete occDialogInfo) if the destructor of 
 	 * this object hasn't been called.  If the destructor has been called, the clean up is done
 	 * in the destructor.
 	 *
 	 * We can use the return valid of AfxUnhookWindowCreate() to differentiate between 2 and 3.
 	 *  - If AfxUnhookWindowCreate() returns true and hWnd==NULL, this means that (2) has happened
 	 *    and we don't have to clean up anything. (Cleanup should be done in the destructor).
 	 *  - If AfxUnhookWindowCreate() returns false and hWnd== NULL, this means that (3) has happened
 	 *    and we need to call PostNcDestroy().
 	 *
 	 * Note: hWnd != NULL implies that AfxUnhookWindowCreate() return TRUE.
         *
         * Note2: From this point on, don't access any member variables without checking hWnd.  If 
         *        hWnd == NULL, the object has been destroyed already.
