PrivateSub TabControl1_DrawItem(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
    'Me.TabControl1.DrawMode = TabDrawMode.OwnerDrawFixed ' 必須先改變模式(可將此句放在Load事件上)
    Dim tabArea As Rectangle
    Dim tabTextArea As RectangleF
    tabArea = TabControl1.GetTabRect(e.Index)
    tabTextArea = CType(TabControl1.GetTabRect(e.Index), RectangleF)
    Dim g As Graphics = e.Graphics
