如何控制外来应用程序的调用和关闭~？（请仔细浏览帖子内容）

Question

unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls;type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;
  StartupInfo:TStartupInfo;
  ProcessInfo:TProcessInformation;
implementation{$R *.DFM}function WinExecExW(cmd,workdir:pchar;visiable:integer):DWORD;
begin
 FillChar(StartupInfo,SizeOf(StartupInfo),#0);
 StartupInfo.cb:=SizeOf(StartupInfo);
 StartupInfo.dwFlags:=STARTF_USESHOWWINDOW;
 StartupInfo.wShowWindow:=visiable;
 if not CreateProcess(nil,cmd,nil,nil,false,Create_new_console or Normal_priority_class,nil,nil,StartupInfo,ProcessInfo) then
   result:=0
 else
   Result:=1;
end;procedure TForm1.FormCreate(Sender: TObject);
begin
  WinExecExW('g:\project1.exe','',1)
end;procedure TForm1.Button1Click(Sender: TObject);
begin  TerminateProcess(ProcessInfo.hProcess,0);
end;end.试过后就明白了
