You can use FindWindow() API and then CloseWindow() api:

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

Declare Function CloseWindow Lib "user32" Alias "CloseWindow" (ByVal hwnd As Long) As Long

To use FindWindow you need to know the window class name.  If you don't know what the class name is you can use GetNextWindow() and GetWindowText() to check the open windows until you find the one you need.  Once you get the hWnd of the window, simply use

Call CloseWindow(hWnd) to terminate that application.

If the window has a caption you can use SendMessage API. Here is a basic example of killing Notepad opened with a blank document.Just paste this onto a form with a command button:

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 Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Const WM_CLOSE = &H10


Private Sub Command1_Click()
Dim Hnd As Long
' Find the window by its caption
Hnd = FindWindow(vbNullString, "Untitled - Notepad")
If Hnd = 0 Then Exit Sub
' send close message to window
SendMessage Hnd, WM_CLOSE, 0&, 0&
End Sub
