Question about CConlistListBox.

[FORAND]

I have a CControlListBox.
I selected 3 elements in it.
How can my program "unselect" one of them?

Thanks

CControlListBox? Never heard of it.

I've heard of CListCtrl and CListBox though. Which are you using?

CListCtrl:
theListCtrl.SetItemState(indexOfSelectedItem, 0, LVIS_SELECTED);

CListBox:
theListCtrl.SetSel(-1, FALSE);

Could someone please help me with SetSel() for CListBox controls? I've been through the MSDN help pages but can't find anything to explain what I'm seeing.

I put 3 strings into the list using the following code, which is in OnInitDialog() :

CListBox *p;
int s;
p = (CListBox*) GetDlgItem (IDC_LIST1);
s = p->AddString ("String 1");
s = p->AddString ("String 2");
s = p->AddString ("String 3");

AddString() returns 0, 1 then 2 and the strings are displayed ok in the dialog.

When I select an option, this code is run:

void CListsDlg::OnSelchangeList1()
{
int s, r;
CListBox *p;

// IDC_LIST1 previously set up with 3 options
p = (CListBox*) GetDlgItem (IDC_LIST1);

// Check whether each option is selected
s = p->GetSel (0);
s = p->GetSel (1);
s = p->GetSel (2);

// Deselect all options
r = p->SetSel (-1, false);

// Select option 1
r = p->SetSel (1, true);
}

GetSel() works fine but SetSel() always returns -1 and the selections I see on the dialog are not updated.

Any help much appreciated!
