VB6|Killing Processes

Well before i start, i already searched with no luck, no code seems to work.
i need an api that will kill a process when form unloads...i have tried numerous kinds so dont tell me to search, thanks in advance

What process do you need to kill? Another application not of your own, when your program ends?

Good example on Killing a Program Process:

:wave:

yeah i cant get that one to work, i tried it before.
im not killing my project, but another..
heres my module:

VB Code:

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

 Public Sub KillProcess(NameProcess As String)
Const PROCESS_ALL_ACCESS = 0
Const TH32CS_SNAPPROCESS As Long = 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

and in my form:

VB Code:

Private Sub Form_Load()
KillProcess (App.Path & "\text1.text")
End Sub

nothing happends at all : /

got it : )
