在论坛一直潜水，快2年了！第一次发帖，功能如题
在论坛找了许久，一直没发现合适的例子可以借鉴，于是自己就各种翻墙，查找资料并DIY这个使用API来控制的实例，现分享给大家，希望给更多人带来帮助

代发分为两部分，Userform和Module
Userform部分

Private Sub ListBox1_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
HookListBoxScroll
End Sub
Private Sub UserForm_Initialize()
LISTBOX_Post_Flag = 1
LISTBOX_Mouse_Flag = 1
Me.Label1.Caption = "默认：光标位置固定,仅滚轮滚动"
End Sub
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
UnhookListBoxScroll
End Sub
Private Sub CommandButton1_Click()
LISTBOX_Post_Flag = 1
LISTBOX_Mouse_Flag = 1
Me.Label1.Caption = "当前状态：光标位置固定,仅滚轮滚动"
End Sub
Private Sub CommandButton2_Click()
LISTBOX_Post_Flag = 1
LISTBOX_Mouse_Flag = 2
Me.Label1.Caption = "当前状态：光标位置不固定,跟随滚轮滚动"
End Sub
