Kill all processes with a certain name - vbscript

I have an HTA that runs a backup routine. For the backup I'm using the SyncToy command line executable, which in some instances does not properly cease.
Beacuse of this, I'm trying to kill any process with the name SyncToyCmd.exe. I make use of the window_onBeforeUnload event and call the KillSyncToy() sub from there.
The function is correctly detecting instances of the SyncToyCmd.exe, however when trying to kill the process I'm receiving an error -
Error: The system cannot find the file specified.
I'm guessing that I'm doing something wrong here and any assistance would be welcome.
Sub KillSyncToy()
Dim WMIService : Set WMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\.\root\cimv2")
Dim ProcessList : Set ProcessList = WMIService.ExecQuery("SELECT * FROM Win32_Process WHERE Name = 'SyncToyCmd.exe'")
Dim Process
For Each Process in ProcessList
'** Note that 'Shell' is a global instace of the 'WScript.Shell' object, so
'there is no need to declare it here *'
Shell.Exec "PSKill " & Process.ProcessId
Next
Set WMIService = Nothing
Set ProcessList = Nothing
End Sub

The error message means that Exec can't find pskill.exe, so the executable most likely isn't located in the %PATH% or the current working directory. You could mitigate that by specifying the full path to the executable.
However, the objects returned from querying Win32_Process have a Terminate method. I'd recommend using that instead of shelling out:
For Each Process in ProcessList
Process.Terminate
Next

How to run loop check vbs for particular running process? Or missing process?

I am running the following VBScript (check.vbs):
Set service = GetObject ("winmgmts:")
For Each Process In Service.InstancesOf("Win32_Process")
If Process.Name = "cmd.exe" Then
WScript.Echo "cmd running"
WScript.Quit
End If
Next
CreateObject("WScript.Shell").Run("C:\system\file.bat")
This script will check whether cmd.exe is running or not. If it is running, this script will display a message "cmd running". If it is not running, this script will open a batch file C:\system\file.bat.
But what I actually need is: when I run this script check.vbs it needs to keep on checking until it finds that cmd.exe is not running.
Only if it found cmd.exe is not running it needs to run file.bat - after repeated checking in background (like any loop program).
In simple words, when opening check.vbs the script need to continously check that cmd.exe is running or not, once it found it's not running, it need to open file.bat.
Still not sure if I understand the question correctly, but assuming that you actually want a monitor that watches and re-spawns a particular process you could do something like this:
Set wmi = GetObject ("winmgmts://./root/civm2")
Sub CheckProcess(name, script)
For Each p In wmi.ExecQuery("SELECT * FROM Win32_Process")
If p.Name = name Then Exit Sub
Next
CreateObject("WScript.Shell").Run script
End Sub
Do
CheckProcess "cmd.exe", "C:\system\file.bat"
WScript.Sleep 100
Loop

Restart a vbs script if it crashes

I'm trying to make a vb script that will restart another vb script if it crashes.
I have searched, and searched but all I get is how to restart a program and since a vb script is a background process it doesn't work when you search in Win32_Process.
Here is my code
set Service = GetObject ("winmgmts:")
set Shell = WScript.CreateObject("WScript.Shell")
sEXEName = "Test_To_Block.vbs"
while true
bRunning = false
for each Process in Service.InstancesOf ("Win32_Process")
if Process.Name = sEXEName then
bRunning=true
msgbox("I am active")
End If
next
if bRunning=False then
msgbox("I am not active.")
Shell.Run sEXEName
end if
WScript.Sleep(100)
wend
The problem is that it never see's the file running and just opens hundreds of "Test_To_Stop.vbs"'s which resolves in me having to restart the computer.
In my opinion what should be changed is where the code is looking for.
for each Process in Service.InstancesOf ("Win32_Process")
Instead of looking in "Win32_Process" you need to look in wherever background process' run.
I am new to coding so sorry if this is a simple question.
Thank you in advance.

The below code restarts itself via WshShell.Exec() method and trace state of the running script via .Status property of returned object:
If Not WScript.Arguments.Named.Exists("task") Then
Do
With CreateObject("WScript.Shell").Exec("""" & WScript.FullName & """ """ & WScript.ScriptFullName & """ ""/task""")
Do While .Status = 0
WScript.Sleep 1
Loop
End With
Loop
End If
MsgBox "This script will be restarted immediately after termination"
Another way is to use .Run() method with third parameter set to True to wait until launched process terminated:
If Not WScript.Arguments.Named.Exists("task") Then
Do
CreateObject("WScript.Shell").Run """" & WScript.FullName & """ """ & WScript.ScriptFullName & """ ""/task""", 1, True
Loop
End If
MsgBox "This script will be restarted immediately after termination"
Or even simplier:
If Not WScript.Arguments.Named.Exists("task") Then
Do
CreateObject("WScript.Shell").Run """" & WScript.ScriptFullName & """ ""/task""", 1, True
Loop
End If
MsgBox "This script will be restarted immediately after termination"
Probably because the name of the running process is 'wscript.exe' and not 'Test_To_Block.vbs'. You may be able to use the hack mentioned on this page to change the name of the process:
If you're running the scripts locally and running some regular scripts, one
common hack is just to copy and rename wscript.exe to a particular name,
such as "MyScript1.exe". Then run the script with a shortcut as
"...\MyScript1.exe MyScript1.vbs". Then the process will show up as
MyScript1.exe.
Then you can use sEXEName = "MyScript1.exe"
Note: instead of using Shell.run sExeName use Shell.run "Test_To_Block.vbs"

SELECT ProcessId unexpected behaviour inside HTA

First of all, thanks for reading.
I have a HTA to centralize some repetitive task.
Login into several servers via ssh and send multiple commands is one of them.
This code is working like a charm inside a vbs file
Option Explicit
Dim Shell, WMI, wql, process
Set Shell = CreateObject("WScript.Shell")
Set WMI = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
wql = "SELECT ProcessId FROM Win32_Process WHERE Name = 'putty.exe'"
dim cmd : cmd=InputBox("Enter command")
For Each process In WMI.ExecQuery(wql)
Shell.AppActivate process.ProcessId
Shell.SendKeys cmd & " {ENTER}"
Next
But this equivalent, inside a HTA only sends the command to one or two windows.
sub sendToPuttyWindow(cmd)
Dim Shell, WMI, wql, process
Set Shell = CreateObject("WScript.Shell")
Set WMI = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
wql = "SELECT ProcessId FROM Win32_Process WHERE Name = 'putty.exe'"
For Each process In WMI.ExecQuery(wql)
Shell.AppActivate process.ProcessId
Shell.SendKeys cmd & " {ENTER}"
Next
end sub
Currently I'm calling the vbs file from the hta, but I would like to maintain the HTA file as independent as possible.
Could you please help me?
Do not use SendKeys for automating PuTTY. It sends all emulated keystrokes to the current foreground window, whatever that may be. If you need to run several commands in a row: use plink from the PuTTY suite. It was built for this exact purpose.
plink -ssh -batch -m file user#host

mstsc Remote Desktop questions

currently, to improve some inefficiencies on a daily process, I am trying to write a c# Winform app that will combine a mix of user-input with VBscripts that will expedite a previously all user-input process of looking at an excel file and moving files from VSS to certain folders of certain servers.
I was hoping to get some questions answered, pointed in the right way:
Using command line or other workaround instead of manually,
1) Is it possible to log into a 2003 remote desktop with a Smartcard/pin?
2) Is it possible to run a file/start a process on the remote desktop from a command on your machine?
Thanks for the help and time
I have only experience with the second question.
You can do this with remote scripting or with utilities like SysInternals PsExec http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx
here a vbscript that remotely starts a ipconfig command and redirects it to a textfile
Note that you can't start interactive processes like this, they would start but not show up
Dim sComputer 'computer name
Dim sCmdLine 'command line of the process
Dim sCurDir 'working directory of the process
Dim oProcess 'object representing the Win32_Process class
Dim oMethod 'object representing the Create method
sComputer = "." 'this is the local computer, use a pcname or ip-adress to do it remote
sCmdLine = "cmd /c ipconfig.exe > c:\ipconfig.txt"
Set oProcess = GetObject("winmgmts://" & sComputer & "/root/cimv2:Win32_Process")
Set oMethod = oProcess.Methods_("Create")
Set oInPar = oMethod.inParameters.SpawnInstance_()
oInPar.CommandLine = sCmdLine
oInPar.CurrentDirectory = sCurDir
Set oOutPar = oProcess.ExecMethod_("Create", oInPar)
If oOutPar.ReturnValue = 0 Then
WScript.Echo "Create process method completed successfully"
WScript.Echo "New Process ID is " & oOutPar.ProcessId
Else
WScript.Echo "Create process method failed"
End If

How to softly end a process using VBS

I like to end a process using VBScript.
Unfortunally I only found examples in which the authors are describing how to do it killing the process.
I like to ask for closing. So objProcess.Terminate() won't help.
I'm using Windows XP SP3 with admin rights.
Any Ideas?
Thank you!
You could try the CloseMainWindow and the Close methods on the process as described on MSDN, like:
Sub KillingMeSoftly(processName)
'partly copied from http://www.activexperts.com/activmonitor/windowsmanagement/adminscripts/processes/
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colProcessList = objWMIService.ExecQuery _
("Select * from Win32_Process Where Name = '" & processName & "'")
For Each objProcess in colProcessList
objProcess.CloseMainWindow
objProcess.Close
Next
End Sub
this was a bad answer
UPDATE
While searching for an answer, I just discovered that starting a script with the //T:nn option triggers the Terminate event on objects:
class Foo
sub class_terminate
msgbox "Gracefull termination"
' Put your own termination code here.
end sub
end class
dim bar
set bar = new Foo
do
loop ' makes the script run forever
Save this as c:\endless.vbs
Running this script will never trigger the termination event because it will hang in the endless loop, but if you start the script with a timeout it will; Start the script from the command prompt:
C:\>wscript endless.vbs //T:5
You'll see that after 5 seconds a messagebox with "Gracefull termination" appears.
This is usefull when you want to quit a script after a certain amount of time and run a cleanup if it was not ended by itself. I do not know if this covers the solution you are searching for.
So, finally I found a solution for my problem, but is not solved using VBS.
There is a program written to send a CTRL-BREAK to any process called "SendSignal". I had tried this before, but all my process was responding had been an error-message and it kept running.
I changed this program sending CTRL+C. After this I was able to shut my Javaw process gently.
Thanks to all, for your help!
