利用网卡序列号设计软件注册程序(十八)

 

利用网卡序列号设计软件注册程序 ( 十八 )

本文讲述如何利用网卡序列号来设计软件的注册程序。

1.      创建一个对话框工程： NetMACRegDlg

2.      添加一个文本框用来显示获取的网卡地址。

3.      添加一个按钮生成序列号，代码如下：

       CString code ;

       CString regcode , tmp ;

       GetDlgItem ( IDC_MACADDR_EDIT )-> GetWindowText ( code );

       code . MakeLower ();

       CString seg1 , seg2 , seg3 ;

       int num ;

       seg1 = code . Mid (0,4);

       seg2 = code . Mid (5,4);

       seg3 = code . Mid (10,4);

       char * cpseg1 = new char [4];

       char * cpseg2 = new char [4];

       char * cpseg3 = new char [4];

       cpseg1 = seg1 . GetBuffer (0);

       cpseg2 = seg2 . GetBuffer (0);

       cpseg3 = seg3 . GetBuffer (0);

       char temp ;

       int i ;

       for ( i =0; i <4; i ++)

       {

              temp = cpseg1 [ i ];

              if ( temp >= 'a' && temp <= 'f' )

                     num = temp - 'a' +10;

              else

                     num = temp - '0' ;

              tmp . Format ( "%c" , base [ num *4+ i ]);

              regcode += tmp ;

       }

      

       for ( i =0; i <4; i ++)

       {

              temp = cpseg2 [ i ];

              if ( temp >= 'a' && temp <= 'f' )

                     num = temp - 'a' +10;

              else

                     num = temp - '0' ;

              tmp . Format ( "%c" , base [ num *4+ i ]);

              regcode += tmp ;

       }

      

       for ( i =0; i <4; i ++)

       {

              temp = cpseg3 [ i ];

              if ( temp >= 'a' && temp <= 'f' )

                     num = temp - 'a' +10;

              else

                     num = temp - '0' ;

              tmp . Format ( "%c" , base [ num *4+ i ]);

              regcode += tmp ;

       }

       regcode . MakeUpper ();

       GetDlgItem ( IDC_REGCODE_EDIT )-> SetWindowText ( regcode );

其中：

char base [64]={ 'd' , 'c' , 'a' , 'b' , 'h' , 'g' , 'e' , 'f' , 'l' , 'k' ,

'i' , 'j' , 'p' , 'o' , 'm' , 'n' , 't' , 's' , 'q' , 'r' ,

'x' , 'w' , 'u' , 'v' , 'b' , 'a' , 'y' , 'z' , 'f' , 'e' ,

'c' , 'd' , 'j' , 'i' , 'g' , 'h' , 'n' , 'm' , 'k' , 'l' ,

'r' , 'q' , 'o' , 'p' , 'v' , 'u' , 's' , 't' , 'z' , 'y' ,

'j' , 't' , 'o' , 'v' , 'w' , 'm' , 'q' , 'x' , 'p' , 'f' ,

'w' , 'x' , 'd' , 'c' };

用来实现简单的加密来计算序列号。

4.      OnInitDialog () 来获取网卡地址

       // 以下是获取 MAC 地址

       NCB ncb ;

       LANA_ENUM lenum ;

       ADAPTER_STATUS state ;

       UCHAR ucReturnCode ;

       ncb . ncb_command = NCBENUM ;

       ncb . ncb_buffer =( UCHAR *)& lenum ;

       ncb . ncb_length = sizeof ( lenum );

       ucReturnCode = Netbios (& ncb );

       if ( lenum . length >=0)

       {

              int num = lenum . lana [0];

              UCHAR buf [128];

              memset (& ncb ,0, sizeof ( ncb ));

              ncb . ncb_command = NCBRESET ;

              ncb . ncb_lana_num = num ;

              ucReturnCode = Netbios (& ncb );

              memset (& ncb ,0, sizeof ( ncb ));

              ncb . ncb_command = NCBASTAT ;

              ncb . ncb_lana_num = num ;

              ncb . ncb_buffer =( unsigned char *)& state ;

              ncb . ncb_length = sizeof ( state );

              strcpy ( ( char *) ncb . ncb_callname , "*" );

              ucReturnCode = Netbios (& ncb );

              CString strMac ;

              strMac . Format ( "%02X%02X-%02X%02X-%02X%02X/n" ,

                     state . adapter_address [0],

                     state . adapter_address [1],

                     state . adapter_address [2],

                     state . adapter_address [3],

                     state . adapter_address [4],

                     state . adapter_address [5]);

              GetDlgItem ( IDC_MACADDR_EDIT )-> EnableWindow ( FALSE );

              GetDlgItem ( IDC_MACADDR_EDIT )-> SetWindowText ( strMac );

 

       }

注意：要包含头文件： #include "nb30.h";link 中添加： netapi32.lib 。或者用下面的语句：

#pragma comment(lib, "netapi32.lib" )

完成。
