当你辛辛苦苦用DELPHI做好了一个你认为十分不错的程序,你是否想把它发布出去成为共享软件呢 做为一个共享软件,注册码肯定是少不了的,你可以通过判断程序是否注册来进行功能,时间或一些其它限制.现在就介绍一种简单的注册码制造方法.思路是这样的:程序运行时先检测注册表,如果找到注册项,则表明已经注册,如果没有找到注册项,则提示要求注册.
<注册例程>
在DELPHI下新建一工程,放置Edit1,Edit2,Label1,Label2,Button1组件.具体代码如下:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls,Registry;//在此加上Registry以便调用注册表.
type
TForm1 = class(Tform)
Button1: Tbutton;
Edit1: Tedit;
Edit2: Tedit;
Label1: Tlabel;
Label2: Tlabel;
procedure Button1Click(Sender: Tobject);
procedure FormCreate(Sender: Tobject);
private
Function Check():Boolean;
Procedure CheckReg();
Procedure CreateReg();
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
Pname:string; //全局变量,存放用户名和注册码.
Ppass:integer;
implementation
{$R *.DFM}
Procedure TForm1.CreateReg();//创建用户信息.
var Rego:Tregistry;
begin
Rego:=Tregistry.Create;
Rego.RootKey:=HKEY_USERS;
rego.OpenKey('.DEFAULTSoftwareAngelSoftDemo',True);//键名为AngelSoftDemo,可自行修改.
Rego.WriteString('Name',Pname);//写入用户名.
Rego.WriteInteger('Pass',Ppass);//写入注册码.
Rego.Free;
ShowMessage('程序已经注册,谢谢!');
CheckReg; //刷新.
end;
Procedure TForm1.CheckReg();//检查程序是否在注册表中注册.
var Rego:Tregistry;
begin
Rego:=Tregistry.Create;
Rego.RootKey:=HKEY_USERS;
IF Rego.OpenKey('.DEFAULTSoftwareAngelSoftDemo',False) then
begin
Form1.Caption:='软件已经注册';
Button1.Enabled:=false;
Label1.Caption:=rego.ReadString('Name');//读用户名.
Label2.Caption:=IntToStr(Rego.ReadInteger('Pass')); //读注册码.
rego.Free;
end
else Form1.Caption:='软件未注册,请注册';
end;
Function TForm1.Check():Boolean;//检查注册码是否正确.
var
Temp:pchar;
Name:string;
c:char;
I,Long,Pass:integer;
begin
Pass:=0;
Name:=edit1.Text;
long:=length(Name);
for I:=1 to Long do
begin
temp:=pchar(copy(Name,I,1));
c:=temp^;
Pass:=Pass+ord(c); //将用户名每个字符转换为ASCII码后相加.
end;
if StrToInt(Edit2.Text)=pass then
begin
Result:=True;
Pname:=Name;
Ppass:=Pass;
end
else Result:=False;
end;
procedure TForm1.Button1Click(Sender: Tobject);
begin
if Check then CreateReg
else ShowMessage('注册码不正确,无法注册');
end;
procedure TForm1.FormCreate(Sender: Tobject);
begin
CheckReg;
end;
end.
<注册器>
在DELPHI下新建一工程,放置Edit1,Edit2,Button1组件.具体代码如下:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls;
type
TForm1 = class(Tform)
Button1: Tbutton;
Edit1: Tedit;
Edit2: Tedit;
procedure Button1Click(Sender: Tobject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.Button1Click(Sender: Tobject);
var
Temp:pchar;
Name:string;
c:char;
I,Long,Pass:integer;
begin
Pass:=0;
Name:=edit1.Text;
long:=length(Name);
for I:=1 to Long do
begin
temp:=pchar(copy(Name,I,1));
c:=temp^;
Pass:=Pass+ord(c);
end;
edit2.text:=IntToStr(pass);
end;
end.
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.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.
