Question

如果用VB获取某个进程的PID,要简单的!

例如获取lsass.exe的PID
写代码,不需要判断或者其他功能,最简单的获取lsass.exe的PID
有更简单的吗?可以简略解释一下吗?

Answer 1

新建个模块然后加入以下代码

Option Explicit
Private Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long
Public Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long, ByVal uExitCode As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Sub CloseHandle Lib "kernel32" (ByVal hPass As Long)
Private Const TH32CS_SNAPPROCESS = &H2&
Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * 260
End Type
Const PROCESS_TERMINATE = 1
Function GetPsPid(sProcess As String) As Long
Dim lSnapShot As Long
Dim lNextProcess As Long
Dim tPE As PROCESSENTRY32
lSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0&)
If lSnapShot <> -1 Then
tPE.dwSize = Len(tPE)
lNextProcess = Process32First(lSnapShot, tPE)
Do While lNextProcess
If LCase$(sProcess) = LCase$(Left(tPE.szExeFile, InStr(1, tPE.szExeFile, Chr(0)) - 1)) Then
Dim lProcess As Long
Dim lExitCode As Long
GetPsPid = tPE.th32ProcessID

CloseHandle lProcess
End If
lNextProcess = Process32Next(lSnapShot, tPE)
Loop
CloseHandle (lSnapShot)
End If
End Function

调用GetPsPid("进程名")

在form1窗体是加入按钮控件和编辑框控件然后计入代码运行输入进程名然后就可以

看到pid了。

Private Sub Command1_Click()
Print GetPsPid(Text1.Text)
End Sub
经过测试完全可用。。。。。就这样了

这个就算最简单的API函数的 声明了。模块部分都是一样的
