问题
I need a VBScript that will check if a process is in use by a specific user:
Agent clicks program icon --> batch file calls for progcheck.vbs -->
progcheck.vbs looks to see is "whatever.exe" is running under that user only -->
if program is running under that user then MsgBox "Program running" --> wscript.quit (this needs to terminate out of the batch file)
else --> return to batch file.
I have tried this with tasklist in a batch file and the script works, but takes forever to run for a domain user. Want to do this in vbscript anyway.
*** UPDATED SCRIPT WITH MODS 10/12 *****
OPTION EXPLICIT
DIM strComputer,strProcess, strUserName,wshShell
Set wshShell = WScript.CreateObject( "WScript.Shell" )
strUserName = wshShell.ExpandEnvironmentStrings( "%USERNAME%" )
strComputer = "." '
strProcess = "notepad.exe"
IF isProcessRunning(strComputer,strProcess,strUserName) THEN
If MsgBox ("Notepad needs to be closed.", 1) = 1 then
wscript.Quit(1)
End If
END IF
FUNCTION isProcessRunning(BYVAL strComputer,BYVAL strProcessName,BYVAL strUserName)
DIM objWMIService, strWMIQuery
strWMIQuery = "Select * from Win32_Process where name like '" & strProcessName & "' AND owner like '" &strUserName& "'"
SET objWMIService = GETOBJECT("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
IF objWMIService.ExecQuery(strWMIQuery).Count > 0 THEN
isProcessRunning = TRUE
ELSE
isProcessRunning = FALSE
END If
End Function
Let me know what you think and where I have it wrong. Thanks in advance.

UPDATED CODE v3: review comments for help
OPTION EXPLICIT
DIM strComputer, strProcess, strUserName, wshShell
Set wshShell = WScript.CreateObject( "WScript.Shell" )
strUserName = wshShell.ExpandEnvironmentStrings( "%USERNAME%" )
strComputer = "."
strProcess = "notepad.exe" 'change this to whatever you are trying to detect
IF isProcessRunning(strComputer, strProcess, strUserName) THEN
If MsgBox ("Notepad needs to be closed.", 1) = 1 then
wscript.Quit(1) 'you need to terminate the process if that's your intention before quitting
End If
Else
msgbox ("Process is not running") 'optional for debug, you can remove this
END IF
FUNCTION isProcessRunning(ByRef strComputer, ByRef strProcess, ByRef strUserName)
DIM objWMIService, strWMIQuery, objProcess, strOwner, Response
strWMIQuery = "SELECT * FROM Win32_Process WHERE NAME = '" & strProcess & "'"
SET objWMIService = GETOBJECT("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2").ExecQuery(strWMIQuery)
IF objWMIService.Count > 0 THEN
msgbox "We have at least ONE instance of Notepad"
For Each objProcess in objWMIService
Response = objProcess.GetOwner(strOwner)
If Response <> 0 Then
'we didn't get any owner information - maybe not permitted by current user to ask for it
Wscript.Echo "Could not get owner info for process [" & objProcess.Name & "]" & VBNewLine & "Error: " & Return
Else
Wscript.Echo "Process [" & objProcess.Name & "] is owned by [" & strOwner & "]" 'for debug you can remove it
if strUserName = strOwner Then
msgbox "we have the user who is running notepad"
isProcessRunning = TRUE
Else
'do nothing as you only want to detect the current user running it
isProcessRunning = FALSE
End If
End If
Next
ELSE
msgbox "We have NO instance of Notepad - Username is Irrelevant"
isProcessRunning = FALSE
END If
End Function
You can use the following function:
FUNCTION isProcessRunning(BYVAL strComputer,BYVAL strProcessName)
DIM objWMIService, strWMIQuery
strWMIQuery = "Select * from Win32_Process where name like '" & strProcessName & "'"
SET objWMIService = GETOBJECT("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
IF objWMIService.ExecQuery(strWMIQuery).Count > 0 THEN
isProcessRunning = TRUE
ELSE
isProcessRunning = FALSE
END IF
END FUNCTION
For local computer you would use "."
For the process name, you would use the executable "notepad.exe"
For the rest of the code, you could can use something simple:
OPTION EXPLICIT
DIM strComputer,strProcess
strComputer = "." ' local computer
strProcess = "notepad.exe" 'whatever is the executable
IF isProcessRunning(strComputer,strProcess) THEN
'do something
ELSE
'do something else or nothing
wscript.echo strProcess & " is NOT running on computer '" & strComputer & "'"
END IF
That should do it.
EXTRA
To show every process running, then just run:
Option Explicit
Dim objWMIService, objProcess, colProcess
Dim strComputer, strList
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set colProcess = objWMIService.ExecQuery _
("Select * from Win32_Process")
For Each objProcess in colProcess
strList = strList & vbCr & _
objProcess.Name
Next
WSCript.Echo strList
WScript.Quit
回答2:
in terminal server this function can be very slow, all the GetOwner calls are terrible in performance.
A very fast solution i created is to narrow the query using SessionID of the current user (assuming we want only current user's processes) So I added this code:
SessionID can be obtained this way:
Dim oExec, sOutput, iUserPos, iUserLen, iStatePos, SessionID
dim oShell, userName
Set oShell = CreateObject("Wscript.Shell")
userName = oShell.ExpandEnvironmentStrings("%USERNAME%")
Set oExec = oShell.Exec("query session %username%")
sOutput = LCase(oExec.StdOut.ReadAll)
iUserPos = InStr(sOutput, LCase(userName))
iStatePos = InStr(sOutput, "active")
iUserLen = Len(userName)
SessionID = CInt(Trim(Mid(sOutput, iUserPos+iUserLen, iStatePos-iUserPos-iUserLen)))
Changed the function from the previous post:
Function isProcessRunning(ByRef strComputer, ByRef strProcess, ByRef strUserName, byRef sessionID)
DIM objWMIService, strWMIQuery, objProcess, strOwner, Response
strWMIQuery = "SELECT * FROM Win32_Process WHERE SessionId = " & sessionID & " And NAME = '" & strProcess & "'"
SET objWMIService = GETOBJECT("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2").ExecQuery(strWMIQuery)
IF objWMIService.Count > 0 THEN
'msgbox "We have at least ONE instance of Notepad"
For Each objProcess in objWMIService
Response = objProcess.GetOwner(strOwner)
If Response = 0 Then
'Wscript.Echo "Process [" & objProcess.Name & "] is owned by [" & strOwner & "]" 'for debug you can remove it
if strUserName = strOwner Then
'msgbox "we have the user who is running notepad"
isProcessRunning = TRUE
Else
'do nothing as you only want to detect the current user running it
isProcessRunning = FALSE
End If
'else
'we didn't get any owner information - maybe not permitted by current user to ask for it
'Wscript.Echo "Could not get owner info for process [" & objProcess.Name & "]" & VBNewLine & "Error: " & Return
End If
Next
ELSE
'msgbox "We have NO instance of Notepad - Username is Irrelevant"
isProcessRunning = FALSE
END If
End Function
