CListBox::GetCurSel
Retrieves the zero-based index of the currently selected item, if any, in a single-selection list box.
int GetCurSel( ) const;
Return Value
The zero-based index of the currently selected item if it is a single-selection list box. It is LB_ERR if no item is currently selected.
In a multiple-selection list box, the index of the item that has the focus.
Remarks
Do not call GetCurSel for a multiple-selection list box. Use CListBox::GetSelItems instead.
Example
// Select the next item of the currently selected one.
int nIndex = m_myListBox.GetCurSel();
int nCount = m_myListBox.GetCount();
if ((nIndex != LB_ERR) && (nCount > 1))
{
if (++nIndex < nCount)
m_myListBox.SetCurSel(nIndex);
else
m_myListBox.SetCurSel(0);
}
