给VB窗体加滚动条是否有新的办法

[li_net]

程序所有窗体已设计好了，用加图片的方法实现似乎已很困难，请问大家是否有什么新的办法？谢谢

看这个吧：

窗体多的话，处理事件建议用superclass

[rainstormmaster]

加滚动条本身很容易，一两句代码就可以实现，关键是我们加的滚动条要能响应事件，所以没什么简单的办法

偶现在用的也是关于图片的超长窗体,楼主可试试下面方法:
先在窗体上拖一个双屏幕长的frame1框(你的所有内容都可以在这上面拖出),高18000;宽15085;(窗体的属性Scalemode取1-Twip)
然后拖水平与垂直的两个滚动条;(注意:要在窗体上拖出)
Vscrloo1(竖滚动条)属性:LargeChange=20000,Max=11055
HScroll1(横)属性:LargeChange=8000;Max=1000;Top=18000;Width=14040
上面是偶的选用参数,你也可自选;
建立一个模块:下面代码放进去
Option Explicit

下面代码放在窗体中:

VScroll1.Visible = True
Else
VScroll1.Visible = False

End If

VScroll1.Left = Me.ScaleWidth - VScroll1.Width
VScroll1.Top = 0

VScroll1.Height = Me.ScaleHeight

End Sub
Private Sub Form_Unload(Cancel As Integer)
UnHook Me.hwnd

Frame1.Top = -VScroll1.Value
End Sub
Private Sub VScroll1_GotFocus() '此段可防止滚动条闪烁,借用一个按钮控件
Command1.SetFocus
