VB.NET怎样列出以及关闭当前所有进程用cmd中的taskkill结束程序
shell”cmd/c taskkill /f /im 你的进程名.exe“
vb.net如何获取当前进程的cpu和内存使用率？使用wmi
类“Win32_Processor”中LoadPercentage属性为当前的cpu使用率
示例代码： Private Sub Timer1_Timer()
Dim WMI服务 As Object
Dim 对象 As Object
Dim 子对象 As Object
Dim 电脑名 As String
Dim 刷新 As Long
刷新 = 0
电脑名 = "." '表示本地计算机
Set WMI服务 = GetObject("winmgmts://"电脑名"/root/cimv2")
Set 对象 = WMI服务.InstancesOf("Win32_Processor")
Me.CurrentX = 0
Me.CurrentY = 0
For Each 子对象 In 对象
If 刷新 = 0 Then
刷新 = 1
Me.Cls
End If
Me.Print 子对象.Name"["子对象.CurrentClockSpeed"Hz] 使用率:"_
子对象.LoadPercentage"%"
Next
End Sub
vb.net中如何设置进程的基本优先级下面的代码示例说明了更改线程优先级的结果 。创建两个线程，其中一个线程的优先级设置为 BelowNormal 。两个线程在 while 循环中都增加一个变量，并运行一段设定的时间 。
Option Explicit
Option Strict
Imports System
Imports System.Threading
Public Class Test
MTAThread _
Shared Sub Main()
Dim priorityTest As New PriorityTest()
Dim threadOne As Thread = _
New Thread(AddressOf priorityTest.ThreadMethod)
threadOne.Name = "ThreadOne"
Dim threadTwo As Thread = _
New Thread(AddressOf priorityTest.ThreadMethod)
threadTwo.Name = "ThreadTwo"
threadTwo.Priority = ThreadPriority.BelowNormal
threadOne.Start()
threadTwo.Start()
' Allow counting for 10 seconds.
Thread.Sleep(10000)
priorityTest.LoopSwitch = False
End Sub
End Class
Public Class PriorityTest
Dim loopSwitchValue As Boolean
Sub New()
loopSwitchValue = https://www.04ip.com/post/True
End Sub
WriteOnly Property LoopSwitch As Boolean
Set
loopSwitchValue = https://www.04ip.com/post/Value
End Set
End Property
Sub ThreadMethod()
Dim threadCount As Long = 0
While loopSwitchValue
threadCount += 1
End While
Console.WriteLine("{0} with {1,11} priority "_
"has a count = {2,13}", Thread.CurrentThread.Name, _
Thread.CurrentThread.Priority.ToString(), _
threadCount.ToString("N0"))
End Sub
End Class
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 =PivbTabsFilevbTabdFilevbTab1vbTabDelNvbTabcrvbTabcgvbTabcbvbTabIndexI
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操作文件进程总被占…经常遇到这样的问题，检查进程里都没有，但就是提示进程被占 。到底是文件打开后使用完要及时关闭 。
未关闭，这样再打开就显示处于被占用状态 。
vb.net 怎么结束进程好像不难吧？
我放进vb.net运行进程数了Button1的Click事件里 。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo Errmessages'在做系统操作时加排错标签是个好习惯
Dim TargetName As String = "ibmdict" '存储进程名为文本型vb.net运行进程数，注vb.net运行进程数：进程名不加扩展名
Dim TargetKill() As Process = Process.GetProcessesByName(TargetName) '从进程名获取进程
Dim TargetPath As String'存储进程路径为文本型
If TargetKill.Length1 Then'判断进程名的数量，如果同名进程数量在2个以上，用For循环关闭进程 。
For i = 0 To TargetKill.Length - 1
