How to kill process from LN

I found this approach as very good for my purposes. It works at least . I suppose that there are another couple even better approach, so if you know them share please.

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
'-------------------------------------------------------
Declare Function OpenProcess Lib "kernel32.dll" (Byval dwDesiredAccess As Long, Byval blnheritHandle As Long, Byval dwAppProcessId As Long) As Long
Declare Function ProcessFirst Lib "kernel32.dll" Alias "Process32First" (Byval hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function ProcessNext Lib "kernel32.dll" Alias "Process32Next" (Byval hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function CreateToolhelpSnapshot Lib "kernel32.dll" Alias "CreateToolhelp32Snapshot" (Byval lFlags As Long, lProcessID As Long) As Long
Declare Function TerminateProcess Lib "kernel32.dll" (Byval ApphProcess As Long, Byval uExitCode As Long) As Long
Declare Function CloseHandle Lib "kernel32.dll" (Byval hObject As Long) As Long


Public Sub KillProcess(NameProcess As String)
Const PROCESS_ALL_ACCESS = &H1F0FFF
Const TH32CS_SNAPPROCESS = 2&
Dim uProcess As PROCESSENTRY32
Dim RProcessFound As Long
Dim hSnapshot As Long
Dim SzExename As String
Dim ExitCode As Long
Dim MyProcess As Long
Dim AppKill As Boolean
Dim AppCount As Integer
Dim i As Integer
Dim WinDirEnv As String

If NameProcess <> "" Then
AppCount = 0

uProcess.dwSize = Len(uProcess)
hSnapshot = CreateToolhelpSnapshot(TH32CS_SNAPPROCESS, 0&)
RProcessFound = ProcessFirst(hSnapshot, uProcess)

Do
i = Instr(1, uProcess.szexeFile, Chr(0))
SzExename = Lcase$(Left$(uProcess.szexeFile, i - 1))
WinDirEnv = Environ("Windir") + "\"
WinDirEnv = Lcase$(WinDirEnv)

If Right$(SzExename, Len(NameProcess)) = Lcase$(NameProcess) Then
AppCount = AppCount + 1
MyProcess = OpenProcess(PROCESS_ALL_ACCESS, False, uProcess.th32ProcessID)
AppKill = TerminateProcess(MyProcess, ExitCode)
Call CloseHandle(MyProcess)
End If
RProcessFound = ProcessNext(hSnapshot, uProcess)
Loop While RProcessFound
Call CloseHandle(hSnapshot)
End If
End Sub

You can use the windows command TASKKILL and shell to that.

For example:

taskkill /F /FI "IMAGENAME eq notepad.exe"

will shut down all open applications of notepad.exe.
