然后打开你的VB程序,点击文件--打开工程--选择你保存源程序的代码档搜的文件夹,选择工程文件(VBP\VBG文件) ,确定.
现在可以先按F5来试运行,没问题,点击文行肢历件饥宴---生成XXXXX.EXE --一路下去就OK啦!
得说明是什么型号的PLC啊，串口还是网口，VB6还是VB.NET？

VB源程序如下：
Option Base 1
Private Sub Command1_Click()
Dim A(5, 5) As Integer, B(5, 5) As Integer
For x = 1 To 弊雀5
For y = 1 To 5
A(x, y) = Int(10 + Rnd * 乱卜慧90) '随机产生两位数的整数
Print A(x, y) '输出
Next
Next
For x = 1 To 5
For y = 1 To 5
B(x, y) = A(y, x) '转置
Print B(x, y) '输出
Next
Next
End Sub
程序输出结果如下：
扩展资料：
VB：编写程序，实现如下规律的5*5矩阵哗答存入数组，并输出该数组
Private Sub Command1_Click()
Dim a(1 To 6, 1 To 6) As Integer
For i = 1 To 5
For j = 1 To 5
tmp = 99
If i <tmp Then
tmp = i
End If
If j <tmp Then
tmp = j
End If
If 6 - i <tmp Then
tmp = 6 - i
End If
If 6 - j <tmp Then
tmp = 6 - j
End If
a(i, j) = tmp
Next j
Next i
For i = 1 To 5
For j = 1 To 5
Picture1.Print Tab(j * 5)a(i, j)
Next j
Picture1.Print
Next i
End Sub
程序输出结果如下：
