Excel VBA 如何实现改变单元格内容后自动更新到数据库？不知道代码哪里有问题，请指教
Private Sub Worksheet_Change(ByVal Target As Range)


Dim i, j As Integer
Dim k As Range
Dim a As Boolean
Dim CR As Range



i = Target.Row
j = Target.Column
If i >= 3 Then


For Each k In Target.Cells

a = IsNumeric(RTrim(k.Offset(0, -j).Value))
If a = False Then
Exit Sub
Else

Update_leads_feedback RTrim(k.Offset(0, -j).Value), Trim(k.Offset(-(i - 1), 0).Value), k.Value
End If
Next
End If
End Sub


Sub Update_leads_feedback(ByVal iLeadsID As Long, iColumnName As String, iComment As String)
Dim conn As New ADODB.Connection
Dim cmd As New ADODB.Command
conn.Open cnnstr()
cmd.ActiveConnection = conn
cmd.CommandText = "SP_Leads_ForSalse_FeedBack_Update"
cmd.CommandType = adcmdstoreproc
Dim owner As ADODB.Parameter
Dim LeadsID As ADODB.Parameter
Dim ColumnName As ADODB.Parameter
Dim Comment As ADODB.Parameter

owner = cmd.CreateParameter(, adVarChar, adParamInput, 255, login())
LeadsID = cmd.CreateParameter(, adInteger, adParamInput, 500, iLeadsID)
ColumnName = cmd.CreateParameter(, adVarChar, adParamInput, 255, iColumnName)
Comment = cmd.CreateParameter(, adVarChar, 255, iComment)

With cmd.Parameters
.Append owner
.Append LeadsID
.Append ColumnName
.Append Comment

End With
cmd.Execute
conn.Close
Set conn = Nothing
End Sub





[解决办法]
应该是 k.Offset(0, -j) 超出了有效单元格的范围吧！

[解决办法]
是　Cells(k.Cells.Row, 1).Value 的数值太大吧！ CInt() 溢出了。

CInt()函数 参数的值域是：-32768 ～ 32767

超出范围就溢出了。
