Excelcombobox滚动鼠标

我试图与彼得桑顿代码，使选项滚动鼠标在一个combobox和列表框，一个选项是不是内置在Excel中，它为用户界面Comboxes和列表框令人惊讶，但我似乎无法理解如何使此代码为工作表上的常规combobox工作

当前用户表单代码：

 Private Sub cmbMyList_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single) HookListBoxScroll Me, Me.cmbMyList End Sub Private Sub lbxMyList_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single) HookListBoxScroll Me, Me.lbxMyList End Sub Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer) UnhookListBoxScroll End Sub 

当前combobox代码：

  Private Sub ComboBox1_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single) End Sub
