权限管理系统之软件注册模块

转自：http://www.VEVb.com/jara/

软件注册是商业软件必不可少的模块，在整个程序中启到举足轻重的作用。

系统启动时首先会检测程序是否注册，如果程序没有注册可以使用30次，试用次数完成后将弹出注册界面。程序每次登陆都会将程序使用次数写入到注册表中，程序注册是也会将注册码已加密的方式写入到注册表中。

   public static void RegMetod(bool isDownLoad)        {            try            {                SoftReg softReg = new SoftReg();                //判断软件是否注册                RegistryKey retkey = Registry.CurrentUser.OpenSubKey("SOFTWARE", true).CreateSubKey(Encrypt.EncryptDES("mySoftWare", Const.EncryptKey)).CreateSubKey(Encrypt.EncryptDES("Register.INI", Const.EncryptKey));                foreach (string strRNum in retkey.GetSubKeyNames())                {                    if (Encrypt.DecryptDES(strRNum, Const.EncryptKey) == softReg.GetRNum())                    {                        run(isDownLoad, "正式版", "");                        return;                    }                }                Int32 tLong;                try                {                    tLong = (Int32)Registry.GetValue("HKEY_LOCAL_MACHINE//SOFTWARE//" + Encrypt.EncryptDES("mySoftWare", Const.EncryptKey), "UseTimes", 0);                }                catch                {                    Registry.SetValue("HKEY_LOCAL_MACHINE//SOFTWARE//" + Encrypt.EncryptDES("mySoftWare", Const.EncryptKey), "UseTimes", 0, RegistryValueKind.DWord);                }                tLong = (Int32)Registry.GetValue("HKEY_LOCAL_MACHINE//SOFTWARE//" + Encrypt.EncryptDES("mySoftWare", Const.EncryptKey), "UseTimes", 0);                if (tLong < 30)                {                    int tTimes = tLong + 1;                    Registry.SetValue("HKEY_LOCAL_MACHINE//SOFTWARE//" + Encrypt.EncryptDES("mySoftWare", Const.EncryptKey), "UseTimes", tTimes);                    int xint = 30 - tTimes;                    //试用版不提供更新服务                    run(true, "试用版", xint.ToString());                }                else                {                    DialogResult result = Comm.MessageBox.YesNo("试用次数已到!您是否需要注册?");                    if (result == DialogResult.Yes)                    {                        RegisterForm registerForm = new RegisterForm();                        registerForm.ShowDialog();                    }                    else                    {                        application.Exit();                    }                }            }            catch (Exception e)            {                Log.Error("程序注册出错!");                throw new Exception("程序注册出错:" + e.Message);            }        }

注册界面：

        #region * 注册        PRivate void btnReg_Click(object sender, EventArgs e)        {            if (string.IsNullOrEmpty(this.txtLicence.Text))            {                Client.Win.Comm.MessageBox.Info("注册码不能为空!");                return;            }            try            {                if (txtLicence.Text == softReg.GetRNum())                {                    Client.Win.Comm.MessageBox.Info("注册成功！重启软件后生效！");                    RegistryKey retkey = Registry.CurrentUser.OpenSubKey("Software", true).CreateSubKey(Encrypt.EncryptDES("mySoftWare", Const.EncryptKey)).CreateSubKey(Encrypt.EncryptDES("Register.INI", Const.EncryptKey)).CreateSubKey(Encrypt.EncryptDES(txtLicence.Text, Const.EncryptKey));                    retkey.SetValue(Encrypt.EncryptDES("UserName",Const.EncryptKey),Encrypt.EncryptDES( "Rsoft",Const.EncryptKey));                    this.Close();                }                else                {                    Client.Win.Comm.MessageBox.Warn("注册码错误！");                    txtLicence.SelectAll();                }            }            catch (Exception ex)            {                throw new Exception(ex.Message);            }        }        #endregion

生成机器码（由MAC地址和硬盘券盘号截取前面20位）：

     ///<summary>        /// 生成机器码        ///</summary>        ///<returns></returns>        public string GetMNum()        {            string strNum = Computer.Instance().MacAddress + Computer.Instance().VolumeSerialNumber; // GetCpu() + GetDiskVolumeSerialNumber();            string strMNum = string.Empty;            if (strNum.Length > 20)            {                strMNum = strNum.Substring(0, 20);    //截取前20位作为机器码            }            else            {                strMNum = strNum;            }            return strMNum;        }
