注册热键(20分)

我想注册一个"全局热键",当在任何窗口中按下"F9"就执行sndPlaySound(s,0)函数.怎么样注册这个热键呢.
用RegisterHotKey函数吗?该怎么写

设置全局快捷键

procedure FormCreate(Sender: TObject);

procedure hotykey(var msg:TMessage);
message WM_HOTKEY;
end;

var
Form1: TForm1;
id,id2:Integer;

implementation
{$R *.DFM}

procedure TForm1.hotykey(var msg:TMessage);
begin

if (msg.LParamLo=MOD_CONTROL) and (msg.LParamHi=81) then

begin

ShowMessage('Ctrl + Q ');
end;

if (msg.LParamLo=MOD_CONTROL) and (msg.LParamHi=82) then

begin

ShowMessage('Ctrl + R ');
end;

end;


procedure TForm1.FormCreate(Sender: TObject);
begin

id:=GlobalAddAtom('hotkey');
RegisterHotKey(handle,id,mod_control,81);

id2:=GlobalAddAtom('hotkey2');
RegisterHotKey(handle,id2,mod_control,82);
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin

UnRegisterHotKey(handle,id);
UnRegisterHotKey(handle,id2);
end;

大哥,我是说只注册热键只需按一个按钮"F9"我要的不是组合键。

这样可以的.试试.
unit Unit1globaladdatom;
interface
uses

Dialogs;
type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
private
{ Private declarations }
procedure HotKeyProc(Var msg:TWMHotKey);message WM_HotKey;
public
{ Public declarations }
end;

var
Form1: TForm1;
HotKey1:word;
implementation
{$R *.dfm}
procedure TForm1.FormCreate(Sender: TObject);
begin
HotKey1:=GlobalAddAtom('nnss');
RegisterHotKey(handle,HotKey1,0,VK_F9);
//热键是F9
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
UnRegisterHotKey(handle,HotKey1)
end;

procedure TForm1.HotKeyProc(var msg: TWMHotKey);
begin
showmessage('hi');
end;

end.
