مساعدة في قريد فيو

انا استخدم الكود التالي

وشغال معي في البرنامج

 For Each Row As GridViewRow In GridView2.Rows
            'If DateDiff("h", Row.Cells(5).Text, Row.Cells(6).Text) < "24" Then

            Row.Cells(7).Text = DateDiff("n", Row.Cells(5).Text, Row.Cells(6).Text) & " min"
        Next
        For Each Row As GridViewRow In GridView2.Rows
            If Row.Cells(7).Text = "196 min" Then 'And Row.Cells(9).Text = "false" Then
                Row.BackColor = Drawing.Color.Maroon
                Row.ForeColor = Drawing.Color.White
                Dim con As New OleDbConnection("Provider=MSDAORA.1;Password=eee;User ID=emp;Data Source=expora;Persist Security Info=True")

                Dim cmd As New OleDbCommand("UPDATE emp_req SET late ='yes' WHERE sno = " & Row.Cells(0).Text, con)
                Dim cmd1 As New OleDbCommand("UPDATE emp_req SET MAIL_SENT ='true' WHERE sno = " & Row.Cells(0).Text, con)

                ' Dim RecNo = (GridView2.Rows(Row.RowIndex).Cells(0).Text.ToString)
                'cmd.Parameters.AddWithValue("SNO", RecNo)

                Try
                    con.Open()
                    cmd.ExecuteNonQuery()
                    cmd1.ExecuteNonQuery()
                Finally
                    con.Close()
                End Try

end if
next

بس المشكلة لما نقلت المشروع في IIs

هذا الكود لم يعد يعمل لماذا

ارجووووووو المساعدة
