else

halt;

{把当前进程变为一个系统服务，从而在任务列表中把程序隐藏起来}

procedure 1Click(Sender: TObject);

begin

;

end;

procedure 2Click(Sender: TObject);

begin

close;

end;

{退出时释放全局热键}

procedure ose(Sender: TObject; var Action: TCloseAction);

begin

UnRegisterHotKey(handle,id);

GlobalDeleteAtom(id);

end;

end.

或者用以下是工程文件,不显示运行窗口!

lize;

Form(TForm1,Form1);

inForm:=False; //不显示运行窗口

;
