    AxSftTree1.ColumnsObj.MakeOptimal() ' Make all columns optimal

    ' triple the size of the last column
    AxSftTree1.get_Column(1).WidthPix = AxSftTree1.get_Column(1).WidthPix * 3

    AxSftTree1.Items.RecalcHorizontalExtent() ' Update horizontal scrollbar

    AxSftTree1.Items.Current = 0 ' select the first item
