How to check this event: user change selection with arrow keys in CListCtrl

// in MessageMap:
ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST, &CMyDialog::OnLvnItemchangedListAll)
// and function:
void CMyDialog::OnLvnItemchangedListAll(NMHDR *pNMHDR, LRESULT *pResult)
{
	LPNMLISTVIEW pNMLV = reinterpret_cast<lpnmlistview>(pNMHDR);
	// TODO: Add your control notification handler code here
	int iCurIndex = m_cListAll.GetSelectionMark();
	CString csItemText = m_cListAll.GetItemText(iCurIndex, 1);
	TRACE(L"%s\n", csItemText); // TRACE IS CALLED 3 TIMES :confused: so if i call here a other function they will be called 3 times??
        // like this here:
        PrintData(csItemText); // this is called 3 times too!
	*pResult = 0;
}
</lpnmlistview>
