设计模式：
通过使用char数组来实现字符串隐藏；
具体请看示例代码：
==================================================
源码如下：复制内容到剪贴板代码:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Button2: TButton;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
var
t:array of char; //用数组来实现隐藏
begin
t:=Char(103);
t:=Char(111);
t:=Char(111);
t:=Char(100);
t:=Char(32);
t:=Char(106);
t:=Char(111);
t:=Char(98);
t:=Char(44);
t:=Char(32);
t:=Char(109);
t:=Char(97);
t:=Char(110);
t:=Char(33);
Showmessage(t); //英文的“good job, man!”
end;
procedure TForm1.Button2Click(Sender: TObject);
var
t:array of char; //用数组来实现隐藏
begin
t:=Char(185);
t:=Char(167);
t:=Char(207);
t:=Char(178);
t:=Char(196);
t:=Char(227);
t:=Char(163);
t:=Char(172);
t:=Char(215);
t:=Char(162);
t:=Char(178);
t:=Char(225);
t:=Char(179);
t:=Char(201);
t:=Char(185);
t:=Char(166);
t:=Char(193);
t:=Char(203);
t:=Char(163);
t:=Char(161);
Showmessage(t); //中文的“恭喜你，注册成功了！”
end;
end.有人会觉得这样写代码很累，没关系，这里有批量生成上面结果的代码，我正用之...
且上面代码均为其生成之...
edit1.text输入你的提示字符串，edit2.text输入为你预定义的变量名，默认为't'...
点击即可生成像上面的代码，保存在ByTeCrypt.txt，直接copy使用之...复制内容到剪贴板代码:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Edit1: TEdit;
Edit2: TEdit;
Label1: TLabel;
GroupBox1: TGroupBox;
Label2: TLabel;
Label3: TLabel;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
var
wFile:TextFile;
wFileName,s,t:String;
i:Integer;
begin
s:=Edit1.Text;
t:=Edit2.Text;
if length(s)=0 then
begin
showmessage('Please input your string');
exit;
end;
if length(t)=0 then
begin
showmessage('请输入变量名');
exit;
end;
t:=Edit2.Text;
wFileName:= 'ByTeCrypt.txt';
AssignFile(wFile, wFileName);
Rewrite(wFile);
Writeln(wFile,'var');
Writeln(wFile,''+t+':array of char;'); //生成定义t:array of char
Writeln(wFile,'begin');
for i:=1 to Length(s) do
begin
Writeln(wFile, ''+t+'['+IntToStr(i)+']:=Char('+IntToStr(Ord(s))+');'); //生成语句t[？]:=Char(？);
end;
Writeln(wFile,'Showmessage('+t+');');
Writeln(wFile,'end;');
CloseFile(wFile);
showmessage('执行完毕，请查看同目录下ByTeCrypt.txt文件!');
end;
end. 这方面值得参考一下，哈哈。
