//全局变量,存放用户名和注册码.<br> PPass:integer;<br> <br> implementation<br> <br> {$R *.DFM}<br> <br> Procedure TForm1.CreateReg();//创建用户信息.<br> var Rego:TRegistry;<br> begin<br> Rego:=TRegistry.Create;<br> Rego.RootKey:=HKEY_USERS;<br> rego.OpenKey('.DEFAULT\Software\AngelSoft\Demo',True);//键名为AngelSoft\Demo,可自行修改.<br> Rego.WriteString('Name',PName);//写入用户名.<br> Rego.WriteInteger('Pass',PPass);//写入注册码.<br> Rego.Free;<br> ShowMessage('程序已经注册,谢谢!');<br> CheckReg; //刷新.<br> end;<br> <br> Procedure TForm1.CheckReg();//检查程序是否在注册表中注册.<br> var Rego:TRegistry;<br> begin<br> Rego:=TRegistry.Create;<br> Rego.RootKey:=HKEY_USERS;<br> IF Rego.OpenKey('.DEFAULT\Software\AngelSoft\Demo',False) then<br> begin<br> Form1.Caption:='软件已经注册';<br> Button1.Enabled:=false;<br> Label1.Caption:=rego.ReadString('Name');//读用户名.<br> Label2.Caption:=IntToStr(Rego.ReadInteger('Pass')); //读注册码.<br> rego.Free;<br> end<br> else Form1.Caption:='软件未注册,请注册';<br> end;<br> <br> Function TForm1.Check():Boolean;//检查注册码是否正确.<br> var<br> Temp:pchar;<br> Name:string;<br> c:char;<br> i,Long,Pass:integer;<br> begin<br> Pass:=0;<br> Name:=edit1.Text;<br> long:=length(Name);<br> <br> for i:=1 to Long do<br> begin<br> temp:=pchar(copy(Name,i,1));<br> c:=temp^;<br> Pass:=Pass+ord(c); //将用户名每个字符转换为ASCII码后相加.<br> end;<br> if StrToInt(Edit2.Text)=pass then<br> begin<br> Result:=True;<br> PName:=Name;<br> PPass:=Pass;<br> end<br> else Result:=False;<br> end;<br> <br> procedure TForm1.Button1Click(Sender: TObject);<br> begin<br> if Check then CreateReg<br> else ShowMessage('注册码不正确,无法注册');<br> end;<br> <br> procedure TForm1.FormCreate(Sender: TObject);<br> begin<br> CheckReg;<br> end;<br> <br> end.<br> <br> <br> <注册器><br> <br> 在DELPHI下新建一工程,放置Edit1,Edit2,Button1组件.具体代码如下:<br> <br> unit Unit1;<br> <br> interface<br> <br> uses<br> Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,<br> StdCtrls;<br> <br> type<br> TForm1 = class(TForm)<br> Button1: TButton;<br> Edit1: TEdit;<br> Edit2: TEdit;<br> procedure Button1Click(Sender: TObject);<br> private<br> { Private declarations }<br> public<br> { Public declarations }<br> end;<br> <br> var<br> Form1: TForm1;<br> <br> implementation<br> <br> {$R *.DFM}<br> <br> procedure TForm1.Button1Click(Sender: TObject);<br> var<br> Temp:pchar;<br> Name:string;<br> c:char;<br> i,Long,Pass:integer;<br> begin<br> Pass:=0;<br> Name:=edit1.Text;<br> long:=length(Name);<br> <br> for i:=1 to Long do<br> begin<br> temp:=pchar(copy(Name,i,1));<br> c:=temp^;<br> Pass:=Pass+ord(c);<br> end;<br> edit2.text:=IntToStr(pass);<br> end;<br> <br> end.<br> <br> 从<注册器>中取得注册码,便可在<注册例程>中进行注册.原理是使用ORD函数取得用户名每单个字符的ASCII码值,并进行相加得到注册码.<br> 当然,这十分容易并破解,你可以用XOR进行异或操作,或者倒取反值...具体的要看你怎么实现了.总之,本文章只抛砖引玉罢了. </td> </tr></tbody></table></center></div><hr align="center" SIZE="1" width="700"><p align="center" class="ourfont"><span><span><font color="#000000"> <a style="color: rgb(0,0,0);
