我对VBA和编码一般还是很陌生。我在这段代码中苦苦挣扎，我想复制表“ System 1”中A行中的数据，并在验证列表中使用它。但是，使用当前的这段代码，似乎我是从当前工作表而不是从工作表“ System 1”中获取行数据
我在这里做错了什么？参考其他工作表以优化excel速度表时的最佳实践是什么？
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim range1 As Range, rng As Range
Set Sheet = Sheets("System 1")
Set range1 = Sheets("System 1").Range("A1:BB1")
Set rng = Range("M2")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & Name & "'!" & .range1.Address
End With
答案 0 :(得分：0)
此代码应为您提供一个良好的开端。修复并调整您的需求。仔细研究代码的自定义部分。 “ WSChange ”应该可以正常运行，除了那些公共变量可能有些怪异（您总是可以将它们放入过程中……而事件却是……我不明白它们，但是我很快就会知道。如果我发现了一些改进，我将编辑答案并发布一条消息。
我差点忘了。您不能使用其他工作表中的范围来将其用作验证范围（类似于条件格式，适用于Excel 2003），因此必须定义一个名称来用作范围。
这是一个模块。我只是在工作表中看不到它。抱歉。

还有一些“ 事件”，虽然不太好，但是我已经忍耐不住了。
这实际上进入了“ 系统1 ”工作表。您也许应该为“主”表找出类似的东西。
