我是新手,软件的注册算法这一过程如何写? 有的软件通过简单的输入用户名,决定注册码;而又有的软件是通过机器码、EMAIL、用户名这三个条件决定注册码,那个机器码是怎么得出的?这一种算法是否会因为更换硬件(如CPU,换大容量硬盘)而引起用户必须重新取注册码的问题?能否给几个示范代码吧。 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 一般都是硬盘idunit Unit1;interfaceuses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls;type TForm1 = class(TForm) Label1: TLabel; Edit1: TEdit; Label2: TLabel; Edit2: TEdit; Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end;var Form1: TForm1;implementation{$R *.DFM}function encrypt(serial:string):string;var i:dword; len:dword; r:dword;begin r:=0; len:=length(serial); for i:=1 to len do begin r:=r+dword(serial[i]); r:=r*10; end; result:=inttostr(r);end;procedure TForm1.Button1Click(Sender: TObject);begin edit2.text:=encrypt(edit1.text);end;end. unit Unit1;interfaceuses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, registry;type TSrbIoControl = packed record HeaderLength : ULONG; Signature : Array[0..7] of Char; Timeout : ULONG; ControlCode : ULONG; ReturnCode : ULONG; Length : ULONG; end; SRB_IO_CONTROL = TSrbIoControl; PSrbIoControl = ^TSrbIoControl; TIDERegs = packed record bFeaturesReg : Byte; // Used for specifying SMART "commands". bSectorCountReg : Byte; // IDE sector count register bSectorNumberReg : Byte; // IDE sector number register bCylLowReg : Byte; // IDE low order cylinder value bCylHighReg : Byte; // IDE high order cylinder value bDriveHeadReg : Byte; // IDE drive/head register bCommandReg : Byte; // Actual IDE command. bReserved : Byte; // reserved.
