使用vba增加excel列引用？ Z到AA，AA到AB

Question

必需：引用列表中的列值。

一个工作表中有n行，每个单元格都有一个列表，该列表是从另一个工作表中的列值引用的。 我创建了以下代码，但它在Z之后中断，因为ASCII值不适用于AA，AB，......

如何使用VBA为所有行创建列表？

Sub createList()
'creating custom list referencing cells from another sheet

Sheets("Checklist").Select
Dim i As Integer

For i = 1 To 100

    Dim k As String
    k = "='Parameter Options'!$" & Chr(64 + i) & "$1:$" & Chr(64 + i) & "$10"

    'Parameter Options is the sheet i am taking list values from

    Range("A" & i & ":C" & i).Select

    With Selection.Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
        xlBetween, Formula1:=k
    End With

Next i
End Sub

Answer 1

将Range.Address属性与external：= true一起使用可捕获工作表名称以及单元格范围地址。 当您在循环中递增时， Range.Offset属性会错开您的选择。

Sub createList()
    'don't declare your vars inside a loop!!!
    Dim k As String, i As Long

    For i = 1 To 100

        With Worksheet("Parameter Options")
            k = "=" & .Range("A1:A10").Offset(0, i - 1).Address(external:=True)
            'debug.print k
        End With

        'Parameter Options is the sheet i am taking list values from
        With Worksheets("Checklist").Range("A" & i & ":C" & i).Validation
            .Delete
            .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
                Operator:=xlBetween, Formula1:=k
        End With

    Next i
End Sub

Answer 2

使用代码时，您不需要列字母 。

Sub createList()
  'creating custom list referencing cells from another sheet

  Dim i As Long

  For i = 1 To 100
    Dim k As String
    k = "='Parameter Options'!R1C" & i & ":R10C" & i

    With Worksheets("Checklist").Range("A" & i & ":C" & i).Validation
      .Delete
      .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:=Application.ConvertFormula(k, xlR1C1, xlA1)
    End With
  Next i

End Sub

Answer 3

使用您的代码，如果您添加此修改，它将正确转换双字母列，但正如注释中所述，您最好使用列号，更直接。

但是，对于一个简单的快速解决方案，这将做到：

Dim i As Integer

    Dim k As String
    Dim col As String

For i = 1 To 100

    If i < 27 Then
        col = Chr(64 + i)
    Else
        col = Chr(64 + Int(i / 26)) & Chr(64 + i - (Int(i / 26) * 26))
    End If

    k = "='Parameter Options'!$" & col & "$1:$" & col & "$10"

    'Parameter Options is the sheet i am taking list values from

    Range("A" & i & ":C" & i).Select

    With Selection.Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
        xlBetween, Formula1:=k
    End With

Next i

Answer 4

这是我的解决方案。 我在另一个内部生成一个循环，以处理代码ASCII中Z发生的值。

希望这可以帮到你：

For i = 0 To RecordSet.Fields.Count - 1 'This is my data source
    If Ascii > 90 Then
        Ascii = 65
        For y = i To RecordSet.Fields.Count - 1
            Hoja1.Range("A" & Chr(Ascii) & 3).Value = RecordSet.Fields(y).Name
            Ascii = Ascii + 1
        Next
    Else
        Hoja1.Range(Chr(Ascii) & 3).Value = RecordSet.Fields(i).Name
        Ascii = Ascii + 1
    End If
Next

Answer 5

使用模数算术查找列大于702（=三个字母）的列的解决方案。 注意：它不检查有效性。

码

Function colChar(colNo As Long) As String
If colNo < 1 Then Exit Function
Dim n As Long
Dim c As Byte
Dim s As String

n = colNo
Do
    c = ((n - 1) Mod 26)    ' locate within A-Z
    s = Chr(c + 65) & s     ' combine characters
    n = (n - c) \ 26        ' check the rest
Loop While n > 0
colChar = s                 ' return character(s)
End Function
