将偶《奥运邮集》“滚动条”代码在此发帖，抛砖引玉,希望看到更好更简捷的方案!
条件:在窗体上放一个高32000,宽15200的Frame控件,再从工具箱拖放水平与垂直二个滚动条,各属性设置如图所示:(图内的红色所示数据是经过一番调试后得出的)；
垂直滚动条VScrollBar——（1）滚动条的高（2）鼠标点击空白区时滚动条移动快慢值（见滚动条示例图）（3）与窗体左边缘距离（4）移动最大值（5）鼠标点击两端黑三角箭头，滚动条移动快慢值（见滚动条示例图）（6）与窗体顶端距离（7）滚动条的宽
水平滚动条HScrollBar——（1）滚动条的垂直方向的高（即条宽）（2）鼠标点击空白区时滚动条移动快慢值（见滚动条示例图）（3）与窗体左边缘距离（4）移动最大值（5）鼠标点击两端黑三角箭头，滚动条移动快慢值（见滚动条示例图）（6）与窗体顶端距离（7）滚动条的总宽度（长度）

制作滚动条除了对属性的设置之外，还要一组代码和一个模块。下面是放在窗体上的有关代码：
偶是知其然，不知其所以然。所以希望各位高手能对下面的代码进行注释，让大家多学点
Private Sub Form_Load()
    Hook Me.hWnd
    If WindowState = 0 Then
    End If
End Sub
Private Sub form_resize()
    If Frame1.Height > Me.Height Then
        VScroll1.Visible = True
    Else
        VScroll1.Visible = False
    End If
    If Frame1.Width > Me.Width Then
        HScroll1.Visible = True
    Else
        HScroll1.Visible = False
    End If
    HScroll1.Left = 0
    HScroll1.Top = Me.ScaleHeight - HScroll1.Height
    VScroll1.Left = Me.ScaleWidth - VScroll1.Width
    VScroll1.Top = 0
    HScroll1.Width = Me.ScaleWidth
    VScroll1.Height = Me.ScaleHeight
    If VScroll1.Visible = True Then
        If HScroll1.Visible = True Then
           HScroll1.Width = Abs(Me.ScaleWidth - VScroll1.Width)
           VScroll1.Height = Abs(Me.ScaleHeight - HScroll1.Height)
        End If
    End If
    HScroll1.Max = (Frame1.Width - Me.Width) + 3 * VScroll1.Width
    VScroll1.Max = (Frame1.Height - Me.Height) + 3 * HScroll1.Height
    HScroll1.ZOrder
    VScroll1.ZOrder
End Sub
Private Sub Form_Unload(Cancel As Integer)
    UnHook Me.hWnd
    For Each pForm In Forms
        Unload pForm
    Next
End Sub
Private Sub HScroll1_Change()
  Frame1.Left = -HScroll1.Value
End Sub
Private Sub VScroll1_Change()
    Frame1.Top = -VScroll1.Value
End Sub
Private Sub VScroll1_GotFocus()
    Command1.SetFocus
End Sub

学习了

补充一点:该“滚动条”方案还必需实现用鼠标滚轮对超长页面进行上下移动。
目前偶发现该模块的一个不足之处，就是每增加一个超长页面都要相应的增加三组代码，一但页面增加多时，软件运行的速度就会很慢。也许这是VB6又一个不可优化的缺陷。

每个需要设置滚动条的窗体,如xj1、xj2、xj3......都要重复下面一组代码（每组代码窗体名有12处）。窗体数量多了，就占用大量的资源，所以工程内窗体越多，软件启动速度越慢。是否有更好的更简便的方案，希望能有高手优化一下这个方案：
要求是：窗体上设有滚动条，且鼠标滚轮也可以移动窗体内的页面上下移动。
    If WHEEL_SCROLL_LINES > xj1.VScroll1.Max Then
        WHEEL_SCROLL_LINES = xj1.VScroll1.Max
    End If
    If wParam = -7864320 Then
                If xj1.VScroll1.Value <= xj1.VScroll1.Max - 1000 Then
                   xj1.VScroll1.Value = xj1.VScroll1.Value + 1000
                Else
                    xj1.VScroll1.Value = xj1.VScroll1.Max
                End If
            ElseIf wParam = 7864320 Then
                If xj1.VScroll1.Value >= 1000 Then
                    xj1.VScroll1.Value = xj1.VScroll1.Value - 1000
                Else
                    xj1.VScroll1.Value = 0
                End If
            End If

不错哦,谢谢分享!
