Do you own the two applications ? Or do you want to kill a third party application from your own application ? ~RaGE();

HWND hWnd = ::FindWindowEx(NULL, NULL, NULL, "Calculator" ); if (!hWnd) { AfxMessageBox("Could not find \"Calculator\" window"); return; } else ::PostMessage(hWnd, WM_CLOSE, 0, 0);

If you can get a handle to the other app the SedMessage( .. WM_CLOSE .. ) or something like that should work fine. Please don't SHOUT at us. Neville Franks, Author of ED for Windows. Free Trial at www.getsoft.com

Then use a user defined message (search for this here on CP or in MSDN), and use SendMessage() or PostMessage() in the first application to send it to your second application. In your second application (the one which ought to be terminated), handle your message in the message map, and end your application calling DestroyWindow() or OnOK() if it is a MFC dialog. ~RaGE();

This is the easiest way in most cases. John
