Costas, This is a summary of what I've tried to do to terminate a shelled windows application: Here I start the program and get the window handle: x% = Shell(commandline$, 3) ShellWindowHWnd% = GetActiveWindow%() Here the user chooses Quit, and I try to kill the shelled program if it is still running: '—try three different methods to kill the window If IsWindow%(ShellWindowHWnd%) <> 0 Then x% = DestroyWindow(ShellWindowHWnd%) End If If IsWindow%(ShellWindowHWnd%) <> 0 Then x% = SendMessage(ShellWindowHWnd%, WM_SYSCOMMAND, SC_CLOSE, b) End If If IsWindow%(ShellWindowHWnd%) <> 0 Then n% = PostMessage(ShellWindowWHnd%, WM_SYSCOMMAND, SC_RESTORE, 0) x% = SetfocusAPI(ShellWindowHWnd%) SendKeys "%{F4}", TRUE End If The SendMessage with WM_SYSCOMMAND SC_CLOSE seems to actually close some programs, but causes others to hang the system. As far as I can tell, the other methods ether do nothing, or simply iconize the running program. Any further thoughts on this? best regards, Selden There are 3 Replies.
