terminating application

[satheshbabur]

Sir,
Please tell me as to how I can terminate an application that was started from vb using the Shell function. How do I acquire the handle to the started application so that it can be terminated.

Please help me as I need this technique to be implemented.

Bye and Regards
Sathesh

Try this (does not work for Win NT/2k):

Private Declare Function ProcessFirst Lib "kernel32" _
Alias "Process32First" (ByVal hSnapshot As Long, uProcess As _
PROCESSENTRY32) As Long
 
Private Declare Function ProcessNext Lib "kernel32" _
Alias "Process32Next" (ByVal hSnapshot As Long, uProcess As _
PROCESSENTRY32) As Long
 
Private Declare Function CreateToolhelpSnapshot Lib "kernel32" _
Alias "CreateToolhelp32Snapshot" (ByVal lFlags As Long, _
lProcessID As Long) As Long
 
Private Declare Function CloseHandle Lib "kernel32" (ByVal _
hObject As Long) As Long
 
Private Declare Function OpenProcess Lib "kernel32" (ByVal _
dwDesiredAccess As Long, ByVal bInheritHandle As Long, _
ByVal dwProcessId As Long) As Long
 
Private Declare Function TerminateProcess Lib "kernel32" (ByVal _
hProcess As Long, ByVal uExitCode As Long) As Long
 
Private Const MAX_PATH = 260
 
Private 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 * MAX_PATH
End Type
 
 
 
Private Function KillApp(myName As String) As Boolean
    Const PROCESS_ALL_ACCESS = 0
    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
    On Local Error GoTo Finish
    appCount = 0
    
    Const TH32CS_SNAPPROCESS As Long = 2&
    
    uProcess.dwSize = Len(uProcess)
    hSnapshot = CreateToolhelpSnapshot(TH32CS_SNAPPROCESS, 0&)
    rProcessFound = ProcessFirst(hSnapshot, uProcess)
    
    Do While rProcessFound
        i = InStr(1, uProcess.szexeFile, Chr(0))
        szExename = LCase$(Left$(uProcess.szexeFile, i - 1))
        If Right$(szExename, Len(myName)) = LCase$(myName) Then
            KillApp = True
            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
 
    Call CloseHandle(hSnapshot)
Finish:
End Function

Since you shelled the program by it's exe file path, you can close it the same way.
