delphi怎样弄全局热键

我做好一个工具 我想按Num7启动 Num8停止 应该怎样写 我很菜 说具体点

Answer 1

private
aatom:atom;
c:atom;
procedure hotkey(var msg:tmessage);message wm_hotkey; //定义全局热键消息事件
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

a,b:integer;
implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
aatom:=globaladdatom('hotkey');
c:=globaladdatom('hotkey1'); //全局热键ID
RegisterHotKey(handle,aatom,MOD_ALT,vk_f12); //注册全局热键
RegisterHotKey(handle,c,MOD_ALT,vk_f11);
end;
procedure TForm1.hotkey(var msg:tmessage); //热键响应事件

begin
if (msg.LParamHi=VK_F12) and (msg.LParamLo=MOD_ALT) then //全局热键 ALT+F12
begin
a:=a+1;
a:=a mod 2;
if a=1 then
checkbox1.Checked:=true
else
checkbox1.Checked:=false
end;
if (msg.LParamHi=VK_F11) and (msg.LParamLo=MOD_ALT) then
b:=b+1;
b:=b mod 2;
if b=1 then
checkbox2.Checked:=true
else
checkbox2.Checked:=false

end;

procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
globalDeleteatom(aatom);
globalDeleteatom(c);
end;

以前写的 改下就行了
