Retrieving selected items


To retrieve the index of the first selected item use GetNextItem(). As its name implies, you can use also use the GetNextItem() function to retrieve the index of the next selected item. The code below prints out the indices of all selected items to the debug window.
// This code prints out the indices of selected items to debug win
 int i = GetNextItem( -1, LVNI_ALL | LVNI_SELECTED);
 while( i != -1 )
 {
	TRACE("%d\n", i );
	i = GetNextItem( i, LVNI_ALL | LVNI_SELECTED);
 }

    *pResult = 0;

  • Example did not work; but MSDN solution did

    Although, in theory it should have worked.

    The solution from MSDN is:

    CListCtrl* pListCtrl = (CListCtrl*) GetDlgItem(IDC_YOURLISTCONTROL);
    ASSERT(pListCtrl != NULL);

    POSITION pos = pList->GetFirstSelectedItemPosition();
    if (pos == NULL)
    TRACE0("No items were selected!\n");
    else
    {
    while (pos)
    {
    int nItem = pList->GetNextSelectedItem(pos);
    TRACE1("Item %d was selected!\n", nItem);
    // you could do your own processing on nItem here
    }
    }

    This did work.
