[RESOLVED] close vb exe fron another vb exe

I have a vb exe on a flash drive that needs price lists and other files updated when plugged into the main pc. To reflect these new prices i need to close and reopen the exe on the flash drive. How ?
I know i can open using shell, but how do i close it?

I don't know if this will work with an exe on the flash drive but it works on my HD.

Code:

---

Option Explicit
Private Sub Command1_Click()
  Dim strAppTitle As String
'Call with
      strAppTitle = "Exact Title bar name of app. Don't include extension."
  CloseProgram (strAppTitle)
End Sub

---

Module Code:

Code:

---

Option Explicit

    Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
    Private Declare Function GetWindowText Lib "user32.dll" Alias "GetWindowTextA" _
    (ByVal hwnd As Long, ByVal lpString As String, ByVal nMaxCount As Long) As Long
    Private Declare Function EnumWindows Lib "user32.dll" _
    (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
         
    Private Target As String
    Private Const WM_CLOSE = &H10

    Private Function EnumCallback(ByVal app_hWnd As Long, ByVal param As Long) As Long
        Dim buf As String * 256
        Dim title As String
        Dim length As Long
        Dim hWndREC As Long
        length = GetWindowText(app_hWnd, buf, Len(buf))
        title = Left$(buf, length)
        If InStr(1, title, Target, 3) <> 0 Then
            PostMessage app_hWnd, WM_CLOSE, 0, 0
        End If
        EnumCallback = 1
    End Function

    Public Sub CloseProgram(app_name As String)
        Target = app_name
        EnumWindows AddressOf EnumCallback, 0
    End Sub

Search the Forums for "Terminate Process" and you will find alot of good code. Then its just Shell or ShellExecute to rerun your app.

Thanks
I should have stated The flash drive forms caption could be a customers name or a lot of things. I do know the name of Flash drive exe and path

What is this "CloseProgram " function? You forgot to include it :)

This example shows how to launch an exe and close it,

Thanks that works if the flash exe is opened from the desktop exe as it tracks the process id of the flash exe, but the flash exe is auto run when inserted

Right, so I guess you would need to enumerate the running files and find the exe you are interested in. Heres one way to do that I posted here, theres probably better/easier ways to get the same job done tho.

Thanks, That works for closing the desktop exe, but it will not allow me to set the path to the flash drive. Both exe have the same name

EEK! I sure did! Sorry about that. I forgot the Module code that includes the API functions:eek2:
I've edited that post and inserted the module.

i got this to work using GetCurrentProcessId Lib "kernel32" ()
The flash drive exe writes the id to a text file. The main program reads the id
and closes the window. Then reopens using shell
Thanks guys
