BEGIN_MESSAGE_MAP(CMyPropertyPage, CPropertyPage)
//{{AFX_MSG_MAP(CMyPropertyPage)
ON_NOTIFY(LVN_ENDLABELEDIT, IDC_LIST_CONTROL, OnEndLabelEdit)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
void CMyPropertyPage::OnEndLabelEdit(NMHDR* pNMHDR, LRESULT* pResult)
{
LV_DISPINFO* pDispInfo = (LV_DISPINFO*)pNMHDR;
if (pDispInfo->item.pszText == NULL)
{
//Used clicked escape
}
else
{
//Data was accepted by user, empty string perhaps?
}
}
