我正在使用以下代码段来确定我的vbscript正在运行的进程ID:
On Error Resume Next
Dim iMyPID : iMyPID = GetObject("winmgmts:root\cimv2").Get("Win32_Process.Handle='" & CreateObject("WScript.Shell").Exec("mshta.exe").ProcessID & "'").ParentProcessId
If Err.Number <> 0 Then Call Handle_Error(Err.Description)
On Error Goto 0
在我的Windows 7(32位)计算机上,大约90%的时间工作,iMyPID
包含当前运行脚本的进程ID。但是,有10%的时间Handle_Error
被调用,并显示错误消息“ SWbemServicesEX:未找到”。
最近,运行Windows 7(64位)的其他人报告称Handle_Error
总是被调用,并显示错误消息“内存不足”。这似乎是一个疯狂的错误消息,只是为了找到你自己的进程ID!
有人可以推荐一种更好的方法吗?

mshta 会立即终止。也许通过使用WMI服务来实现父进程id为时已晚 所以,我会使用类似的东西来消除并发脚本进程。
Function CurrProcessId
Dim oShell, sCmd, oWMI, oChldPrcs, oCols, lOut
lOut = 0
Set oShell = CreateObject("WScript.Shell")
Set oWMI = GetObject(_
"winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
sCmd = "/K " & Left(CreateObject("Scriptlet.TypeLib").Guid, 38)
oShell.Run "%comspec% " & sCmd, 0
WScript.Sleep 100 'For healthier skin, get some sleep
Set oChldPrcs = oWMI.ExecQuery(_
"Select * From Win32_Process Where CommandLine Like '%" & sCmd & "'",,32)
For Each oCols In oChldPrcs
lOut = oCols.ParentProcessId 'get parent
oCols.Terminate 'process terminated
Exit For
Next
CurrProcessId = lOut
End Function
Dim ProcessId
ProcessId = CurrProcessId 'will remain valid indefinitely
WScript.Echo ProcessId

这是一个更好的代码片段:
' ***********************************************************************************************************
' lng_MyProcessID finds and returns my own process ID. This is excruciatingly difficult in VBScript. The
' method used here forks "cmd /c pause" with .Exec, and then uses the returned .Exec object's .ProcessID
' attribute to feed into WMI to get that process's Win32_Process descriptor object, and then uses THAT
' WMI Win32_Process descriptor object's .ParentProcessId attribute, which will be OUR Process ID, and finally
' we terminate the waiting cmd process. Execing cmd is what causes the brief cmd window to flash at start up,
' and I can' figure out out how to hide that window.
' returns: My own Process ID as a long int; zero if we can't get it.

我喜欢Kul-Tigin的想法(+1),而Asok Smith的想法(基于.Exec
)值得尊重(+1),如果隐藏.Exec
,它会更好处理。所以,为了满足我的好奇心,我也玩弄了这个,这就是我所做的。
ts1 = Timer : res1 = CurrProcessId : te1 = Timer - ts1
ts2 = Timer : res2 = ThisProcessId : te2 = Timer - ts2
WScript.Echo "CurrProcessId", res1, FormatNumber(te1, 6), _
vbCrLf & "ThisProcessId", res2, FormatNumber(te2, 6), _
vbCrLf & "CurrProcessId / ThisProcessId = " & te1 / te2
'> CurrProcessId 6946 0,437500
'> ThisProcessId 6946 0,015625
'> CurrProcessId / ThisProcessId = 28
Function ThisProcessId
ThisProcessId = 0
Dim sTFile, oPrc
With CreateObject("Scripting.FileSystemObject")
sTFile = .BuildPath(.GetSpecialFolder(2), "sleep.vbs")
With .OpenTextFile(sTFile, 2, True)
.Write "WScript.Sleep 1000"
End With
End With
With CreateObject("WScript.Shell").Exec("WScript " & sTFile)
For Each oPrc In GetObject("winmgmts:\\.\root\cimv2").ExecQuery(_

我刚刚发现这个线程部分解决了我的问题。 谢谢大家。
“代码无法确定哪个进程ID属于哪个脚本”:true,但由于这是脚本必须实现的第一个任务,因此可以保留生命周期最短的Pid。
Set com = CreateObject("Wscript.Shell")
Set objSWbemServices = GetObject ("WinMgmts:Root\Cimv2")
Set colProcess = objSWbemServices.ExecQuery ("Select * From Win32_Process")
dim toto, thisPid
thisPid=""
toto=200 ' just a high value like 200sec
For Each objProcess In colProcess
If InStr (objProcess.CommandLine, WScript.ScriptName) <> 0 Then
Ptime=((Cdbl(objProcess.UserModeTime)+Cdbl(objProcess.KernelModeTime))/10000000)
if toto > Ptime then
toto = Ptime
thisPid = objProcess.ProcessId
End If
End If
Next
If thisPid="" then
WScript.Echo "unable to get the PID"
Else
WScript.Echo "PID of this script : "&thisPid
End If
除非您更快地解雇脚本,每个人都可以检索他们的Pid,但一切都必须正常。

这是一个更好的,但在JScript(对不起,你把它翻译成VB ......)
var WshShell = WScript.CreateObject("WScript.Shell");
var objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2");
var childProcess =
WshShell.Exec
(
'"' + WshShell.Environment('PROCESS')('ComSpec') + '"'
+
" /C Echo \"Text lines\" && Set /p VarName="
);
childProcess.StdOut.ReadLine();
var current_pid =
objWMIService.ExecQuery
(
"Select * From Win32_Process Where ProcessId=" + childProcess.ProcessID
);
current_pid = (new Enumerator(current_pid)).item().ParentProcessId;
if (current_pid)
{
childProcess.StdIn.WriteLine("value"); // child process should now exit
WScript.Echo("Current PID: " + current_pid);
}
else
{
WScript.StdErr.WriteLine("Get current PID from WMI failed.");
WScript.Quit(7);

要检索VB脚本的自己的进程ID,您可以依赖Process对象的属性CreationDate。
启动VB脚本时,运行脚本的进程将拥有运行相同脚本的所有进程的最新CreationDate。
事实上,它将拥有所有正在运行的进程中最高的CreationDate。
因此,要获得PID,首先要做的是搜索具有最高CreationDate的进程。
'Searching for processes
Dim strScriptName
Dim WMI, wql
Dim objProcess
'
'My process
Dim datHighest
Dim lngMyProcessId
'Which script to look for ?
strScriptName = "WScript.exe"
'strScriptName = "Notepad.exe"
'Iniitialise
datHighest = Cdbl(0)
Set WMI = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
wql = "SELECT * FROM Win32_Process WHERE Name = '" & strScriptName & "'"
'
For Each objProcess In WMI.ExecQuery(wql)
'The next If is not necessary, it only restricts the search to all processes on the current VB Script
'If Instr(objProcess.CommandLine, WScript.ScriptName) <> 0 Then
If objProcess.CreationDate > datHighest Then
'Take the process with the highest CreationDate so far
' e.g. 20160406121130.510941+120 i.e. 2016-04-06 12h11m:30s and fraction
datHighest = objProcess.CreationDate
lngMyProcessId = objProcess.ProcessId
End If
'End If
Next
'Show The result
WScript.Echo "My process Id = " & lngMyProcessId

您可以使用Sleep
中的kernel32
而不是mshta
。
MsgBox GetProcId()
Function GetProcId()
With GetObject("winmgmts:\\.\root\CIMV2:Win32_Process.Handle='" & CreateObject("WScript.Shell").Exec("rundll32 kernel32,Sleep").ProcessId & "'")
GetProcId = .ParentProcessId
.Terminate
End With
End Function
代码取自here。
也基于这种方法there is父进程名称检测。

这不是我的答案,我在一些谷歌小组讨论论坛中发现了这一点......看看它是否对你有帮助。
Set objSWbemServices = GetObject ("WinMgmts:Root\Cimv2")
Set colProcess = objSWbemServices.ExecQuery ("Select * From Win32_Process")
For Each objProcess In colProcess
If InStr (objProcess.CommandLine, WScript.ScriptName) <> 0 Then
WScript.Echo objProcess.Name, objProcess.ProcessId, objProcess.CommandLine

获取当前的processID
In [31]: alphabets # List of alphabets in the string
Out[31]: ['A', 'G', 'A']
In [32]: digits # List of numbers in the string ( Including numbers more than one digit)
Out[32]: ['3', '3']
In [33]: list_of_strings = [alphabets[i]*int(digits[i]) for i in range(0, len(alphabets)-1)] # List of strings after repetition

Powershell可用于检索调用的VBScript进程ID。这种方法利用了exit
命令的可选参数,该参数指定程序的退出代码。而且,如果将WShell.Run
方法的可选第3个参数设置为True
,则在关闭PowerShell之后,它将返回退出代码(这是VBScript进程ID)。
Dim sCmd
Dim WShell
sCmd = _
"powershell -command exit " & _
"(gwmi Win32_Process -Filter " & _
"\""processid='$PID'\"").parentprocessid"
Set WShell = CreateObject("WScript.Shell")
MsgBox WShell.Run(sCmd, 0, True)
