How to Close Executable Programs with API Calls

I am calling executable program through shell API call with a VB6 Program . I can run any executable programs, but I do not know how to close them through API call. Do I have to have a different API call to close the applications?

Please see API call function.

Public Declare Function ShellExecute Lib "shell32.dll" Alias _
"ShellExecuteA" (ByVal hwnd As Long, ByVal lpszOp As _
String, ByVal lpszFile As String, ByVal lpszParams As String, _
ByVal lpszDir As String, ByVal FsShowCmd As Long) As Long


ShellExecLaunchFile = ShellExecute(Scr_hDC, "Open", strPathFile, "", strOpenInPath, SW_SHOWNORMAL)


Thanks,

This will terminate all instances of a running application. MyName should be the .EXE of the program.

VB Code:

Public Function KillAppByName(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
            KillAppByName = 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

Hi brenaaro,

I try to run KillAppByName but I got error like "user defined” type is not defined".

Is there any way that you can send me complete function calls?
