FIX: ClassWizard Generates Bad Code for Tree View Messages (137154)
The information in this article applies to:
- The ClassWizard, when used with:
- Microsoft Visual C++, 32-bit Editions 2.1
This article was previously published under Q137154 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.
