主题：设计了个搜索按键，怎么使用会弹出一个这个错误呢？

搜索按键代码：

Dim txt As String = e.Form.Controls("TextBox13").Text
Dim tbl As Table = Tables("员工档案之办公室")
If txt = "" Then
    tbl.Filter = ""
Else
    txt = "'*" & txt & "*'"
    tbl.Filter = "序号 Like " & txt & " Or 员工姓名 Like " & txt & " Or 性别 Like " & txt & " Or 毕业学校 Like " & txt  & " Or 专业 Like "  & txt & " Or 持证情况 Like " & txt & " Or 联系方式 Like " & txt  & " Or 是否购买社保 Like " & txt & " Or 备注 Like " & txt  

End If

Dim t1 As WinForm.TextBox = e.Form.Controls("TextBox14")
 t1.Value = "本次查询表中共有" & tbl.Rows.count & "条记录"
