Close applications currently running

Is there a way to close "selected" applications that are currently running when doing an installation of software. I would like to have a predefined set of applications that I could shut down quick and easy (Like at the click of a mouse or run a script etc.).

If you have the title of the window in question you can do this

Ok place a command button on your form and a text box leave them with their default names.
Place htis code in the command button click statement.

Dim winHwnd As Long
                Dim RetVal As Long

                winHwnd = FindWindow(vbNullString, Text1.Text)

                Debug.Print winHwnd

                If winHwnd <> 0 Then
                  RetVal = PostMessage(winHwnd, WM_CLOSE, 0&, 0&)
                  If RetVal = 0 Then
                    MsgBox "Error posting message."
                  End If
                  MsgBox Text1.Text + " is not open."
                End If

Place this code in a module:

Option Explicit

    Declare Function FindWindow Lib "user32" Alias _
    "FindWindowA" (ByVal lpClassName As String, _
    ByVal lpWindowName As String) As Long

    Declare Function PostMessage Lib "user32" Alias _
    "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
    ByVal wParam As Long, lParam As Any) As Long

    Public Const WM_CLOSE = &H10

This will give you a little test project.

You will need to know the title of the window you want to close. Type it into the text box and the window with the selected title should close down.

I Hope this is kinda what you were looking for


call exerunning for each of the programs you want to close


call exerunning("notepad.exe")
call exerunning("vladogran.exe")

             Const NILL = 0&
          hProc = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
          ExeRunning = False
          If hProc = 0 Then
              Exit Function
          End If
          Proc.dwSize = Len(Proc)

          lRet = Process32First(hProc, Proc)
          Do While lRet
              Debug.Print Proc.th32ProcessID
              sClean = Left(Proc.szExeFile, InStr(Proc.szExeFile, Chr(0)) - 1)
              sDeighton = ""
              For andy = Len(sClean) To 1 Step -1
                If Mid(sClean, andy, 1) = "\" Then Exit For
                sDeighton = Mid(sClean, andy, 1) & sDeighton
              If UCase(sDeighton) = UCase(ExeFind) Then
                  ExeRunning = True
                  ProcFromprocid = OpenProcess(PROCESS_QUERY_INFORMATION Or _
                  PROCESS_VM_READ, 0, Proc.th32ProcessID)
                  Call GetExitCodeProcess(ProcFromprocid, lpExitCode)
                  Call TerminateProcess(ProcFromprocid, lpExitCode)
                  Exit Function
              End If
              lRet = Process32Next(hProc, Proc)

      End Function
This will list all proccesses running,you could then send a WM_CLOSE to request that the app closes.

Diegton i get this error with your code

Cant find DLL entry point  CreateToolhelp32Snapshot in Kernel32

are you sure that it is in kernal32?
Well first go out of the installing without affecting it by pressing 'Alt+F4'.
Then press 'Ctrl+Alt+Delete' (Delete NOT backspace!)
Choose which program to close then press enter. (only works with Win98 or Win95)

which vewrsion of Windows?  Works on my 95, but may be problems in NT
CreateToolhelp32Snapshot - I did some research

Only works in 95,98,2000

No NT - sorry.  
Okay Cheers....

Ever thought about moving your question into the newbies section or just the straight windows section, Either that or the give the points to your mate section.

>>>I would like to have a predefined set >>of applications that I                         >>could shut down

I would have thought you meant in code that is why you asked it in the VB section...didnt realise you just meant the user to do it.
