How to kill a process of a calling app

[jake]

Hello,

I have an application that calls another application. Depending on what
the user selects from application 2 I would like to kill application 1. How
can I accomplish this? Thanks in advance.

If you want to be notified about user interaction in the other application
(for example, clicking buttons), you will have to utilize a Win32 hook,
typically implemented in a standard Win32 DLL implemented in VC++ or Delphi.

For starting and closing a process, take a look at this code:

\\\
Imports System.Diagnost ics
..
..
..
Dim p As Process = Process.Start(. ..)
....
If...Then
p.CloseMainWind ow()
End If
....
///

The creation of the process is not close application one like the user wanted

Yes, the user can launch the second application using your code, but you
don't go as far as closing the first one.

Obviously, a way of going about it is to pass the Handle of the first
application to the second & using DestroyWindow to kill it off.

Another way to go about it is to get the process name of application one
from application two & then killing application one from that. So, all you
have to do is to GetProcessByNam e etc.

Crouchie1998,

Do you have a sample on how to do this or a link to get me started? I
would appreciate it. Thanks.

MSDN:

---
A thread cannot use 'DestroyWindow' to destroy a window created by a
different thread.
---

Instead, you can send a 'WM_CLOSE' to the window, the window will call
'DestroyWindow' itself.
