Dialog default selection in Listbox

Can any of you VB gurus help me, please?

I have a listbox with three items:


I want AND to be selected when I open the dialog. It sounds a simple task, but I can't for the life of me work out how to achieve it, and make the 0 value of the listindex be selected when the dialog opens.

This is JScript, but should be the same logic.

    var dlg = DOpus.Dlg;
    dlg.window = scriptCmdData.func.sourcetab;
    dlg.template = "RegExpColumnsConfigure";
    dlg.Control("myList").value = "AND";
