Send it a WM_QUIT message or use TerminateProcess...

you use sendmessage or postmessage with the message WM_QUIT or WM_CLOSE (WM_CLOSE is better because it forces the window to close).,,,,

here is an example...


var
  h : HWND;
begin
  h := FindWindow(nil, 'Notepad - Untitled');
  if h <> 0 then begin
    SendMessage(h, WM_CLOSE, 0, 0);
    ShowMessage('Well, we just kill notepad :)');
  end else ShowMessage('There is no such a window at the moment');
end;

Hope this helps...

If you want the program to ask the user if he/she wants to save the currently opened file, you have to send a WM_CLOSE to the main window.
If you don't like this, send a WM_QUIT either to the main window or (and that is what I'm normally doing) to the main thread by using PostThreadMessage(tid,WM_QUIT,0,0);
You can use TerminateProcess, too. But that's quite ugly, because it does NOT perform a CLEAN program shutdown. (Read the documentation of TerminateProcess)

If you look at this question (hurry, it's still open in the moment)

http://www.experts-exchange.com/topics/comp/lang/delphi/Q.10117362

you'll find a solution for that for win95/98.

If you need it to run under NT4, too, and you have Delphi 4, you can download my "enumStuff" unit from my homepage "http://www.madshi.com" in the "sources" section. This unit gives you some handy functions to enumerate all running applications, but it runs only under Delphi 4.

Use this function. But you must give in the processID of the process you want to shut down. You get the processID from both the sources of the other question I mentioned or from the functions in my "enumStuff" unit.

procedure ShutUp_Process(processID: cardinal);
var c1 : cardinal;
begin
  c1:=OpenProcess(PROCESS_ALL_ACCESS,false,pid);
  if c1<>0 then
    try
      TerminateProcess(c1,0);
    finally CloseHandle(c1) end;
end;

you can use EnumWindows() to get all windows in a TStringList or Listbox or whatever..if you need an example let me know.... yeah Madshi is right.. TerminateProcess() is another way to shut down a process...

Madshi, you've given your procedure a nice name :))
