======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - The ClassWizard, used with:
    - Microsoft Visual C++, 32-bit Editions, version 2.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Class Wizard generates the following incorrect code for the
TVN_BEGINLABELEDIT, TVN_ENDLABELEDIT, TVN_GETDISPINFO, TVN_SETDISPINFO, and
TVN_KEYDOWN Tree View Control notification messages.

   void CMyDialog::OnXXXXtreeview1(NMHDR* pNMHDR, LRESULT* pResult)
   {
      NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
      // TODO: Add your control notification hander code here
      *pResult = 0;
   }

RESOLUTION
==========

For TVN_BEGINLABELEDIT, TVN_ENDLABELEDIT, TVN_GETDISPINFO, and TVN_SETDISPINFO,
the pNMHDR parameter should be cast to a TV_DISPINFO*. For example:

   void CMyDialog::OnXXXXtreeview1(NMHDR* pNMHDR, LRESULT* pResult)
   {
      TV_DISPINFO* pTVDispInfo = (TV_DISPINFO*)pNMHDR;
      // TODO: Add your control notification hander code here
      *pResult = 0;
   }

For TVN_KEYDOWN, the pNMHDR parameter should be cast to a TV_KEYDOWN*. For
example:

   void CMyDialog::OnXXXXtreeview1(NMHDR* pNMHDR, LRESULT* pResult)
   {
      TV_KEYDOWN* pTVKeyDown = (TV_KEYDOWN*)pNMHDR;
      // TODO: Add your control notification hander code here
      *pResult = 0;
   }

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This problem was corrected in Visual C++ version 4.0.
