主题：[求助]怎样改动代码使其能在第二个表格中按要求运行

老师好!下面代码已经能在“卷1答”表中运行，在“学生问题频度”表中得出正确结果。我将这些代码放到“卷2答”表的事件datacolchanged中，运行后想将“卷2答”表中得到的结果累积到“学生问题频度”表中。请您帮助我看看这些代码应如何改动才能满足我的要求。

代码和文件如下：

Dim kmdr As DataRow = DataTables("客观问题描述").find("试卷号= '" & DataTables("卷1答").Name.chars(1) & "'")
Dim zmdr As DataRow = DataTables("主观问题描述").find("试卷号= '" & DataTables("卷1答").Name.chars(1) & "'")
Dim kfdr As DataRow = DataTables("客观题答案").find("试卷号 = '" & DataTables("卷1答").Name.chars(1) & "'" )
Dim xswpdr As DataRow = DataTables("学生问题频度").find("学号 = '" & e.DataRow("学号") & "'")
Dim wtzj As String
For Each dr As DataRow In DataTables("卷1答").DataRows
    Dim t1 As String = e.DataRow("客观题1")
    Dim d1 As String = kfdr("客观题1")
    Dim t2 As String = e.DataRow("客观题2")
    Dim d2 As String = kfdr("客观题2")
    Dim t3 As String = e.DataRow("客观题3")
    Dim d3 As String = kfdr("客观题3")
    wtzj = Nothing
    xswpdr("知1") = 0
    xswpdr("知2") = 0
    xswpdr("知3") = 0
    xswpdr("知4") = 0
    If t1 > "" AndAlso t2 > "" AndAlso t3 > "" Then
        Dim ts() As String = {t1, t2, t3}
        Dim ds() As String = {d1, d2, d3}
        For i As Integer = 0 To ts.length-1
            For Each s As String In ts(i)
                If ds(i).Contains(s) = False Then
                    Select Case kmdr("题" & i + 1 & s.ToUpper() & "范")
                        Case "知1"
                            xswpdr("知1") = xswpdr("知1") + 1
                        Case "知2"
                            xswpdr("知2") = xswpdr("知2") +  1
                        Case "知3"
                            xswpdr("知3") = xswpdr("知3") +  1
                        Case "知4"
                            xswpdr("知4") = xswpdr("知4") +  1
                    End Select
                End If
            Next
        Next
        For i As Integer = 0 To ts.length-1
            For Each s As String In ds(i)
                If ts(i).Contains(s) = False Then
                    Select Case kmdr("题" & i + 1 & s.ToUpper() & "范")
                        Case "知1"
                            xswpdr("知1") = xswpdr("知1") + 1
                        Case "知2"
                            xswpdr("知2") = xswpdr("知2") +  1
                        Case "知3"
                            xswpdr("知3") = xswpdr("知3") +  1
                        Case "知4"
                            xswpdr("知4") = xswpdr("知4") +  1
                    End Select
                End If
            Next
        Next
    End If
    For i As Integer = 1 To 7
        If e.DataRow("主观题" & i ) = "f" Then
            Select Case zmdr("题" & i & "范")
                Case "知1"
                    xswpdr("知1") = xswpdr("知1") + 1
                Case "知2"
                    xswpdr("知2") = xswpdr("知2") +  1
                Case "知3"
                    xswpdr("知3") = xswpdr("知3") +  1
                Case "知4"
                    xswpdr("知4") = xswpdr("知4") +  1
            End Select
        End If
