Use the Select property to select a value in the control, if it contains multiple columns. The control selects only selectable items. The SelectableItem property specifies whether the user can select an item. The control looks for the value in the given column. If the value is found in the column, no error is fired. Use the Value property to select a value in a single column control. The SelectCount property specifies if the control has selected items. Use the SelectItem property to select an item given its handle. The SelectionChanged event is fired when user changes the control's selection. Use the ItemByIndex property to access an item given its index. 

The following VB sample selects the "Cell 4" value on the second column:

With ComboBox1
    .BeginUpdate
        .HeaderVisible = False
        .ColumnAutoResize = True
        .Columns.Add "Column 1"
        .Columns.Add "Column 2"
        With .Items
            Dim h As HITEM
                h = .AddItem("Cell 1")
                .CellCaption(h, 1) = "Cell 2"
                h = .AddItem("Cell 3")
                .CellCaption(h, 1) = "Cell 4"
        End With
        .Select("Column 2") = "Cell 4"
    .EndUpdate
End With
