Ctrl+Space無法關閉/打開輸入法怎麼辦

　　xp有一個bug，就是在語言設置更改輸入法的默認關閉/打開輸入法的熱鍵CTRL+SPACE後，無法設置恢復到原來的狀態，就是說你必須在CTRL+SHIFT+SPACE和ALT+SHIFT+SPACE中選擇一個新的熱鍵來替換原來的CTRL+SPACE，這給人們帶來了很多不便。用delphi可以快速解決此問題，本人在XP SP2上試驗通過。。方法是先在語言設置裡，去掉啟用按鍵順序。然後編譯運行下面的程序，點btn1那個按鈕就OK了。!

以下是代碼片段：

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, StdCtrls,registry;

type

TForm1 = class(TForm)

btn1: TButton;

    procedure btn1Click(Sender: TObject);

private

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.btn1Click(Sender: TObject);

var

  reg :TRegistry;

  buffer :array[0..3] of Byte;

begin

//setLength(buffer,3);

  buffer[0]:= $02;

  buffer[1]:=$c0;

  buffer[2]:=$00;

  buffer[3]:=$00;

  reg:=TRegistry.Create;

  reg.RootKey:=HKEY_CURRENT_USER;

  if(reg.OpenKey('Control PanelInput MethodHot Keys0000010',false)) then

  begin

    reg.WriteBinaryData('Key Modifiers',buffer,4);

    showmessage('ok');

  end;

  reg.Free;

end;

end.
