Using TerminateProcess/ExitProcess

Hi, everybody !
I can't use the API TerminateProcess(hprocess,uexitcode) if I don't know any process (hprocess or uexitcode) information. The only way that I got was the API GetCurrentProcess() but it returns the Handle of my application. Please, I want to do a program like task manager and I want to know the handle of other processes that is running at same time in Windows.
I can use ExitProcess either but I need the parameters too.
Resuming : I want to know how to use TerminateProcess or ExitProcess to kill any process(Program) that is running.

Thanks ! Obs:Answers to [email protected]

This is a purdy good example that seems to work great and is very useful.

Code:

---

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



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


Public 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


Usage

Call KillApp("C:\program.exe")
