[转贴] VBS获取自身PID

Find my own process ID in VBScript
http://stackoverflow.com/questio ... cess-id-in-vbscript

思路1:
1. 使用 WshShell.Exec 启动一个子进程,获取子进程PID,
2. 使用WIM搜索子进程ID对应的父PID

思路2:
1. 获取自身进程启动时间,作短暂延时处理
2. 使用WIM搜索进程时间,查找对应PID


实例1:
  1. On Error Resume Next
  2. Dim iMyPID : iMyPID = GetObject("winmgmts:root\cimv2").Get("Win32_Process.Handle='" & CreateObject("WScript.Shell").Exec("mshta.exe").ProcessID & "'").ParentProcessId
  3. If Err.Number <> 0 Then Call Handle_Error(Err.Description)
  4. On Error Goto 0
  5. Msgbox iMyPID
复制代码
实例2(有黑框):
  1.       ' ***********************************************************************************************************
  2.       ' lng_MyProcessID finds and returns my own process ID. This is excruciatingly difficult in VBScript. The
  3.       ' method used here forks "cmd /c pause" with .Exec, and then uses the returned .Exec object's .ProcessID
  4.       ' attribute to feed into WMI to get that process's Win32_Process descriptor object, and then uses THAT
  5.       ' WMI Win32_Process descriptor object's .ParentProcessId attribute, which will be OUR Process ID, and finally
  6.       ' we terminate the waiting cmd process. Execing cmd is what causes the brief cmd window to flash at start up,
  7.       ' and I can' figure out out how to hide that window.
  8.       ' returns: My own Process ID as a long int; zero if we can't get it.
  9.       ' ************************************************************************************************************
  10. Msgbox lng_MyProcessID
  11. Function lng_MyProcessID ()
  12. lng_MyProcessID = 0                     ' Initially assume failure
  13. Set objChildProcess = CreateObject("WScript.Shell").Exec ( """%ComSpec%"" /C pause" ) ' Fork a child process that just waits until its killed
  14. Set colPIDs= GetObject("winmgmts:").ExecQuery ( "Select * From Win32_Process Where ProcessId=" & objChildProcess.ProcessID,, 0 )
  15. For Each objPID In colPIDs                  ' There's exactly 1 item, but .ItemIndex(0) doesn't work in XP
  16. lng_MyProcessID = objPID.ParentProcessId          ' Return child's parent Process ID, which is MY process ID!
  17. Next
  18. Call objChildProcess.Terminate()                ' Terminate our temp child
  19. End Function ' lng_MyProcessID
