vb.net线程注入 net 线程注入
在vb.net中,多线程如何使用
Sub Main() Dim thr As New Thread(AddressOf 循环) thr.Start("a") End Sub Sub 循环(a() As String) '这里随你干什么循环也行 For Each i As String In a MsgBox(i) Next End Sub

VB.net 如何设计多线程运行
Sub Main()
Dim thr As Thread
For Pi As Integer=0 To 4 //启用5线程
MulParams =Pi vbTab sFile vbTab dFile vbTab 1 vbTab DelN vbTab cr vbTab cg vbTab cb vbTab IndexI
GlobalParamas(pi)=MulParams .Split(vbTab)
thr=New Thread(AddressOf MyMulThreadCaller)
thr.Start() //启动多线程进程
Application.DoEvents
Next
End Sub
vb.NET中如何捕获html页面的动作
你这已经算是外挂的范畴了,用findwindow查找浏览器窗口,然后再浏览器窗口内部再查找那个alert窗口,查到时就给它sendmessage让它确定,这样就达到你想要的效果 了,这是最简单的做法,一个定时 器查不多就搞定了,想做复杂的,就用线程注入,难度 不是一般的大。。
VB.NET 简单多线程
多线程一般是不推荐用的,因为线程之间如果有共享资源的话会引起竞争,需要加锁处理;而且线程间没有时序关系,所以你在调试中可能会出现异步处理结束顺序与开始处理顺序不一致的情况(我在调试中已经发现该问题)。
针对你提出的这个问题,采用了多线程处理,利用的是BackgroundWorker也就是异步处理控件进行了处理。
代码已经经过调试通过。欢迎交流,如有问题,留下QQ或其他联系方式。
代码如下,并附程序截图。
‘---------------------------------------------------
Imports System.ComponentModel '导入异步控件命名空间
Public Class Form1
Private howmany As Integer = 10
Private AnalysisNumber(0 To howmany - 1) As BackgroundWorker
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Items.Clear()
creatNewBackgroundWorker()
addHandle()
startWork()
End Sub
Private Sub creatNewBackgroundWorker()
For i As Integer = 0 To AnalysisNumber.Length - 1
AnalysisNumber(i) = New BackgroundWorker
Next
End Sub
Private Sub addHandle()
For i As Integer = 0 To AnalysisNumber.Length - 1
AddHandler AnalysisNumber(i).DoWork, AddressOf AnalysisNumber_DoWork
AddHandler AnalysisNumber(i).RunWorkerCompleted, AddressOf AnalysisNumber_RunWorkerCompleted
Next
End Sub
Private Sub startWork()
For i As Integer = 0 To 9
Dim temp(0 To 9) As Integer
For j As Integer = 1 To 10
temp(j - 1) = 10 * i + j
Next
AnalysisNumber(i).RunWorkerAsync(temp)
Next
End Sub
Private Sub AnalysisNumber_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs)
Dim data As Integer()
data = CType(e.Argument, Integer())
Dim temp As Integer
For i As Integer = 0 To data.Length - 1
temp = data(i)
data(i) = temp * temp
Next
e.Result = data
End Sub
Private Sub AnalysisNumber_RunWorkerCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs)
Dim data As Integer()
data = CType(e.Result, Integer())
For i As Integer = 0 To data.Length - 1
ListBox1.Items.Add(data(i))
Next
End Sub
End Class
vb.net 多线程操作
将循环放入到另一个线程中
ThreadStart ts = new ThreadStart(delegate() {
//do something
});
Thread t = new Thread(ts);
t.Start();
//going do something
VB.NET 的 后台线程(主线程)如何让它所属的主线程执行一个方法或事件(可以再附加分)
其实最简单的方法是设置一个全局的变量,然后加一个timer,不停显示最新的变量值
