.NET 操作必须使用一个可更新的查询
Private Sub cmdupdate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdupdate.Click
Dim updatesql As String
updatesql = "update authors set au_id= ' " & txtid.Text & " ',au_fname= ' " & txtfirstname.Text & " ',au_lname= ' " & txtlastname.Text & " ',phone= ' " & txtphone.Text & " ',address= ' " & txtaddress.Text & " ',city= ' " & txtcity.Text & " ',state= ' " & txtstate.Text & " ',zip= ' " & txtzip.Text & " ',contract= ' " & Int(chkcontract.Checked) & " 'where au_id= ' " & lstauthor.SelectedItem.Value & " ' "
Dim con As New OleDbConnection(connectionstring)
Dim cmd As New OleDbCommand(updatesql, con)
Try
con.Open()
Dim updated As Integer
updated = cmd.ExecuteNonQuery
lblstatus.Text = updated.ToString() & "records updated. "
Catch err As Exception
lblstatus.Text = "error updating author. "
lblstatus.Text &= err.Message
Finally
If (Not con Is Nothing) Then
con.Close()
End If
End Try
End Sub

[解决办法]
检查用户权限, aspnet(iis5) network service(iis6)的写入权限另检查文件是不是只读
