Private Function MyF(ByRef d() As Integer)
ReDim d(4, 13) As Integer
Dim i As Integer
Dim j As Integer
Dim n As Integer
Dim MyNum(4) As Integer
For i = 1 To 4
MyNum(i) = 0
Next i
Randomize
For i = 1 To 4
For j = 1 To 13
n = Int(Rnd * 4 + 1)
Do While MyNum(n) = 13
n = Int(Rnd * 4 + 1)
Loop
d(i, j) = n
MyNum(n) = MyNum(n) + 1
Next j
Next i
End Function
各们，请教怎么使用vb.net编写两个进程间消息
两个方法
1.
要接收的窗口先使用FindWindow这个api获得句柄
调用SetForegroundWindow使其获得焦点并选中
调用.net方法：SendKeys.Send方法发送
2.使用API的SendInput
使用vb.net编写一个函数，函数只有一个参数
首先在窗体上添加Button1，ListBox1，下面是完整代码
Public Class Form1
Public Sub BubbleSort(ByVal arr() As Integer) '冒泡法排序
Dim temp As Double
Dim i, j As Integer
For i = 0 To arr.GetUpperBound(0) - 1
For j = i + 1 To arr.GetUpperBound(0) - 1
If arr(i) arr(j) Then
temp = arr(j)
arr(j) = arr(i)
arr(i) = temp
End If
Next
Next
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click '调用
Dim arr() As Integer = {55, 22, 33, 11, 77, 88}
BubbleSort(arr) '调用排序过程
Me.ListBox1.Items.Clear()
For i = 0 To arr.GetUpperBound(0) - 1 '显示排序后结果
Me.ListBox1.Items.Add(arr(i).ToString)
Next
End Sub
End Class
vb.net中创建类
不熟悉VB,如有不妥的地方请包涵!
Public Class Stack
Dim aryData() As Integer
Sub New(ByVal Num As Integer)
Dim aryData(Num) As Integer
End Sub
Function Pop() As Integer
If (aryData.Length = 0) Then
Return 0
Else
Dim a As Integer
a = aryData(aryData.Length)
aryData(aryData.Length) = Convert.ToInt32(DBNull.Value)
Return a
End If
End Function
Sub Push(ByVal n As Integer)
For Each i As Integer In aryData
If (aryData(i) = Convert.ToInt32(DBNull.Value)) Then
aryData(i) = n
End
Else
Continue For
End If
Next
End Sub
Sub PrintStack()
For Each i As Integer In aryData
If (aryData(i) = Convert.ToInt32(DBNull.Value)) Then
End
Else
Print(aryData(i))
End If
Next
End Sub
End Class
VB.NET自定义函数
很简单，在end select前再多加一种情况case else return "XXXx",因为你只提供了0-9这10种情况
Public Function Zuhe(ByVal qa As String) As String
Select Case qa
Case "0"
Return "1"
Case "1"
Return "3"
Case "2"
Return "4"
Case "3"
Return "6"
Case "4"
Return "2"
Case "5"
Return "8"
Case "6"
Return "9"
Case "7"
Return "7"
Case "8"
Return "5"
Case "9"
Return "0"
Case else
Return "XXXX"
End Select
End Function
vb 怎么向窗体发送自定义消息
两个进程都是你自己编写的吗？如果是，那就比较简单，直接用DDE连接就可以了。
如果那个窗体不是你自己编的进程，那就只能用API函数了，比如用sendmessage，这需要学习WINDOWS编程，以便学习那个进程的控件可以接受哪些消息，还要受到那个进程是否用采WINDOWS标准控件的限制。
