Delphi基础教程：Ctrl+Space无法关闭/打开输入法怎么办
xp有一个bug，就是在语言设置更改输入法的默认关闭/打开输入法的热键CTRL+SPACE后，无法设置恢复到原来的状态，就是说你必须在CTRL+SHIFT+SPACE和ALT+SHIFT+SPACE中选择一个新的热键来替换原来的CTRL+SPACE，这给人们带来了很多不便。用delphi可以快速解决此问题，本人在XP SP2上试验通过。。方法是先在语言设置里，去掉启用按键顺序。然后编译运行下面的程序，点btn1那个按钮就OK了。!
以下是代码片段：
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.
