Køre extern program og lukke vindue med knap

cmdbuffer: array[0..80] of Char;
cmdbuffer := 'c:\sti\program.exe';
WinExec(cmdbuffer, SW_Show);

Kald program inde fra Delphi program:

procedure ExecuteShellCommand(cmdline: string; hidden: Boolean);
const
  flags: array [Boolean] of Integer = (SW_SHOWNORMAL, SW_HIDE);
var
  cmdbuffer: array [0..MAX_PATH] of Char;
begin
  GetEnvironmentVariable('COMSPEC', cmdBUffer, SizeOf(cmdBuffer));
  StrCat(cmdbuffer, ' /C ');
  StrPCopy(StrEnd(cmdbuffer), cmdline);
  WinExec(cmdbuffer, flags[hidden]);
end;

Luk vinduet/programmet -knap:

procedure TForm1.Button1Click(Sender: TObject);
begin
  Close;
end;

Har brugt lidt fra begge. Der er garanteret en hel del der kan skæres væk, eller hvad?
