So, if ".push" adds an item (I'm assuming to the end of the list), how can you remove an item from an array?

I just looked on a JavaScript site, and it says that ".splice" can be used.  Does this work in Messenger Plus! Live?

Yep. MyArray.splice(index) is what you'll need to do.

Thanks!

JScript code:

---

var SelectedItem = -1;

function OnWndTestEvent_LstViewClicked(PlusWnd,ControlId,ItemIdx) {
    if(ControlId == "vLstTest") {
        SelectedItem = ItemIdx;
        <do_other_stuff>
    }
}

Make sure though that you catch all selection-related events and set SelectedItem accordingly. They are:

• OnWindowIdEvent_LstViewClicked();
  
• OnWindowIdEvent_LstViewDblClicked();
  
• OnWindowIdEvent_LstViewRightClicked();

A value of -1 means that no item is currently selected. That means, for example, there is only one item in the list-view control, and you click below that item.

Also, make sure to set SelectedItem back to -1 when the window is destroyed.

There's another way to get it working without dealing with a variable in those events

JScript code:

---

var LVM_FIRST    = 0x1000;
var LVM_GETNEXTITEM = LVM_FIRST + 12;
var LVNI_SELECTED = 0x2;

var SelectedItem = PlusWnd.SendControlMessage('vLstTest', LVM_GETNEXTITEM, -1, LVNI_SELECTED);

Great!    Thanks, everyone!
