数组内容如下：32 43 76 58 28 12 98 57 31 42 53 64 75 86 97 13 24 35 46 57 68 79 80 59 37
程序运行后，单击窗体，将数据输入二维数组Mat中，在窗体上按5行5列的矩阵形式显示出来，然后计算矩阵第三行各项的和，并在窗体上显示出来
。（因为是考查课，所以没怎么听，简单也不会做，急用，邮到475433452邮箱中，先谢谢啦！！！）

能帮我编一下（ Open App.Path & "\" & "datain.txt" For Input As #1）这个文件吗？？（数据32 43 76 58 28 12 98 57 31 42 53 64 75 86 97 13 24 35 46 57 68 79 80 59 37）

Private Sub Command1_Click()
save Label3
Dim max As Integer
    Dim i As Integer, j As Integer
    max = a(1, 1)
    For i = 1 To 4
        For j = 1 To 4
            If a(i, j) > max Then
                max = a(i, j)
            End If
        Next
    Next
    Label3.Caption = max

End Sub

Private Sub Command2_Click()
save Label4
Dim sum As Integer
    Dim i As Integer
    For i = 1 To 4
        sum = sum + a(i, i)
    Next
    Label4.Caption = sum

End Sub

Private Sub Form_Load()
Open App.Path & "\in5.txt" For Input As #1
    For i = 1 To 4
        For j = 1 To 4
            Input #1, a(i, j)
        Next j
    Next i
    Close #1

End Sub
vb不能运行成功，求帮助！！！！
