创建多个数据验证列表，而不引用相同的范围EXCEL VBA

Question

我正在excel VBA中编写一个宏，该宏在指定单元格中创建数据验证列表。然后，程序提示用户输入包含数据验证列表内容的单元格。然后将包含列表内容的相同行从视图中隐藏起来。但是，当我尝试多次重新运行宏时，每次为内容选择一个新范围时，每个后续列表都会引用该范围。我不希望发生这种情况。

我写了这行代码来防止这种情况:

For Each nm In ThisWorkbook.Names
    strRngNumLbl = strRngNmLbl + 1
Next nm
strRange = strRange & strRngNumLbl

其中string是添加到数据验证时要引用的范围的名称。然而，由于某些原因，这不起作用。我认为这是可行的，因为它将为要添加到列表中的每个范围创建独立的名称。

完整代码如下:

Sub CreatDropDownList()
Dim strRange As String
Dim celNm As Range
Dim celNm2 As Range 'use only if necessary
Dim celRng As Range
Dim strRngNumLbl As Integer
Dim nm As Name

On Error GoTo pressedCancel:
Set celNm = Application.InputBox(Prompt:= _
                "Please select a cell to create a list.", _
                   Title:="SPECIFY Cell", Type:=8)
If celNm Is Nothing Then Exit Sub
'Inserts a copy of the row where the drop down list is going to be
celNm.EntireRow.Copy
ActiveCell.Offset(1).EntireRow.Insert '?

'moves the cell to the appropriate location
celNm.Offset(0, -1).Value = "N/A"
'cell range equal to nothing
Set celRng = Nothing
'asks user to determine range of strings
Set celRng = Application.InputBox(Prompt:= _
    "Please select the range of cells to be included in list.", _
        Title:="SPECIFY RANGE", Type:=8)
If celRng Is Nothing Then Exit Sub
On Error GoTo 0
strRange = "DataRange"
strRngNumLbl = 1
'Increments strRngNumLblb for the number of names present in the workbook to
'ensure list is not referring to duplicate ranges
For Each nm In ThisWorkbook.Names
    strRngNumLbl = strRngNmLbl + 1
Next nm
strRange = strRange & strRngNumLbl
'user defined data range is now called strRange, refer to it as Range(strRange)
ThisWorkbook.Names.Add Name:=strRange, RefersTo:=celRng
'format the refernce name for use in Validation.add
strRange = "=" & strRange
celNm.Offset(-1, 0).Select
'Add the drop down list to the target range using the list range
celNm.Validation.Delete
celNm.Validation.Add xlValidateList, , , strRange
'hide the range where the list came from
celRng.EntireRow.Hidden = True
pressedCancel:
End Sub

有什么建议吗?

Answer 1

解决你的问题

代替:

For Each nm In ThisWorkbook.Names
    strRngNumLbl = strRngNmLbl + 1
Next nm

你应该有:

strRngNumLbl = ThisWorkbook.Names.Count + 1

关于代码的一些提示或问题

我不明白这段代码有什么用:

'Inserts a copy of the row where the drop down list is going to be
celNm.EntireRow.Copy
ActiveCell.Offset(1).EntireRow.Insert '?
'moves the cell to the appropriate location
celNm.Offset(0, -1).Value = "N/A"

这部分我也不明白。此外，如果用户选择a列中的单元格， 可能会导致错误

celNm.Offset(0, -1).Value = "N/A"

希望有帮助，

我能够简单地通过检查是否已经在ThisWorkbook.names中strange名称来解决这个问题。下面是对上面代码的编辑:

For Each nm In ThisWorkbook.Names
    strRngNumLbl = strRngNumLbl + 1
    strRange = strRange & strRngNumLbl
    If strRange = nm Then
        strRngNumLbl = strRngNumLbl + 1
        strRange = strRange & strRngNumLbl
    End If
Next nm
