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.
