实现软件注册的方法

实现软件注册的方法

把刚才的那个方法封装到一个dll中，更方便：

RegDll.dpr：

library RegDLL;

{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }

所用到的md5.pas和我刚才写的那篇文章中的是一样的。

调用方法：

function GetCode():string 获取本机机器码
function GetMD5(MCode:string):string 获取MD5码

调用例子：

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Label1: TLabel;
Edit1: TEdit;
Label2: TLabel;
Edit2: TEdit;
Button1: TButton;
Button2: TButton;
procedure Edit1DblClick(Sender: TObject);
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.dfm}
function GetCode():string;stdcall;external 'RegDLL.dll';
function GetMD5(MCode:string):string;stdcall;external 'RegDLL.dll';

procedure TForm1.Edit1DblClick(Sender: TObject);
begin
Edit1.Text:=GetCode;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
Edit2.Text:=GetMD5(Edit1.Text);
end;

end.
