当工作簿打开时，我试图将数据验证下拉到工作表“数据”中的单元格“B22”中。我收到这个错误

Run-time error '1004'
Application-defined object error

并且应用程序在此代码处中断：

.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
xlBetween, Formula1:=value_list

这是 WorkbookOpen() 子：

Private Sub Workbook_Open()
    Dim oCon As ADODB.Connection
    Dim oRS As ADODB.Recordset
    Dim rng As Range

    Set oCon = New ADODB.Connection
    oCon.ConnectionString = "Provider=SQLOLEDB;Data Source=MARS;Initial Catalog=automation;Trusted_connection=yes;"
    oCon.Open
        Set oRS = New ADODB.Recordset
        oRS.ActiveConnection = oCon
        oRS.Source = "select insurer.name from person as insurer where insurer.person_class_id = 2 order by insurer.name asc"
        oRS.CursorType = adOpenStatic
        oRS.Open
        value_list = ""

     Do While Not oRS.EOF
         value_list = value_list & oRS(0) & ","
         r = r + 1
         oRS.MoveNext
     Loop

     value_list = Mid(value_list, 1, Len(value_list) - 1)

     With Sheets("Data").Range("B22").Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
        xlBetween, Formula1:=value_list
        .IgnoreBlank = True
        .InCellDropdown = True
        .InputTitle = ""
        .ErrorTitle = ""
        .InputMessage = ""
        .ErrorMessage = ""
        .ShowInput = True
        .ShowError = True
    End With

    oRS.Close
    oCon.Close
End Sub

我做了一些测试，发现（至少在 Excel 2003 中）如果value_list长度大于 255 个字符，您将收到此错误。

一种可能的解决方法可能是将列表值加载到命名范围并分配Formula1:="=YourRangeName"，但我尚未对此进行测试。
