显式选项私有m_empList作为字符串

'动态填充下拉列表 Private Sub Workbook_SheetSelectionChange（ByVal Sh作为对象，ByVal目标作为范围）

    ' Since we're changing the Validation each time there is a new Selection;
    ' It's the Active Cell that matters, not the Target range

  If ActiveCell.Row <= 1 Then
    Exit Sub
  End If
    If ActiveCell.Column = 2 And ActiveCell.Row > 1 Then
        If m_empList = "" Then
            m_empList = GetEmployeeList(ActiveCell, Sh.Name)
        End If
       MakeCombo Target, m_empList

'在下拉列表中设置Employee列表子MakeCombo（ByRef目标为范围，ByRef组合列表为字符串）昏暗的cboTemp作为OLEObject 昏暗的工作表暗淡Tgt作为范围昏暗的TgtMrg作为范围调光范围昏暗的TgtW作为双昏暗的AddW只要昏暗的AddH只要

设置ws = ActiveSheet 关于错误继续 '额外的宽度以覆盖下拉箭头 AddW = 15 '覆盖单元格的额外高度 AddH = 5

如果Target.Rows.Count> 1则转到To exitHandler

设置Tgt = Target.Cells（1，1）设置TgtMrg = Tgt.MergeArea 出错时转到errHandler

设置cboTemp = ws.OLEObjects（“ TempCombo”）关于错误继续如果cboTemp.Visible = True，则使用cboTemp .Top = 10 左= 10 .ListFillRange =“” .LinkedCell =“” .Visible = False .Value =“” 结束于如果结束

出现错误时转到errHandler

With cboTemp
  .Visible = True
  .Left = Tgt.Left
  .Top = Tgt.Top
  .Width = Tgt.Width '+ AddW
  .Height = Tgt.Height + AddH
  .ListFillRange = comboList
  .LinkedCell = Tgt.Address
End With
cboTemp.Activate
Me.ActiveSheet.TempCombo.DropDown

exitHandler： Application.EnableEvents =真 Application.ScreenUpdating =真退出子 errHandler：恢复exitHandler
