Closing an app from another app

[Gazzza]

Hi

What I need to do is close a named application through code from another application. There are three apps 1,2 and 3
1 is running 2 is checking that it running and 3 may or may not be running. If 2 detects that 1 is no longer running it needs to shut down 3. I'm using FindWindow to check if 3 is running or not and now I just need to close it. Can anyone help me out. I'm a newbie, so if I need to use an API call could you also tell me a bit about the parameters it will need to be passed.

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Const WM_CLOSE = &H10

Private Sub CloseWindow(hWnd as long)
Call SendMessage(hWnd, WM_CLOSE, 0&, ByVal 0&)
End Sub

Hi,

All you have to do is call the CloseWindow function and specify the hWnd from the window you want to close. The hWnd of the window you are looking for is the returned value of the FindWindow function.

Thats all
