Clistctrl选择检测

Question

I've been playing with the list view and came across this post: How to detect a CListCtrl selection change?

However the code used there has a major flow, it doesn't work with multiple selection (as pointed out in that thread). So my question is how can I make the code work with multiselection (eg. selection with shift or ctrl)?

I've written a handy function to see if your OnItemChanged notification was due to a selection change:

BOOL IsItemSelChanged(NMLISTVIEW* pNMListView)
{
    // call this from your OnItemchangedMyListCtrl function in your dialog class

    if(!(pNMListView->uChanged & LVIF_STATE))
    {
        return(FALSE);
    }

    if((pNMListView->uOldState & LVIS_SELECTED) == (pNMListView->uNewState & LVIS_SELECTED))
    {
        return(FALSE);
    }

    return(TRUE);
}
