录播教室预约系统(三)-DepTable表

DepTable表  主要作用 存放单位名称

如图：

模板下载地址 CodeSmith版本为v6.5

第一步：用CodeSmith模板生成DepTable表相关的存储过程

生成的存储过程如下：

/****** Object:  Stored Procedure [dbo].DepTable_Delete    Script Date: 2015年2月8日 ******/
if exists (select * from [dbo].sysobjects where id = object_id(N‘[dbo].[DepTable_Delete]‘) and OBJECTPROPERTY(id, N‘IsProcedure‘) = 1)
drop procedure [dbo].[DepTable_Delete]
GO

/****** Object:  Stored Procedure [dbo].DepTable_SelectOne    Script Date: 2015年2月8日 ******/

模板生成的DepTable表相关的基础存储过程

DepTable_Insert  插入数据
DepTable_Update  更新数据

DepTable_SelectPage  获取分页数据

DepTable_SelectAll   获取所有数据

DepTable_SelectOne  获取某个数据

DepTable_GetCount 获取数量

DepTable_Delete 删除某个数据

模板生成的数据层代码

主要方法如下：

GetPage  获取分页数据
GetAll  获取所有数据
GetCount 获取总数
GetOne 获取某个数据
Delete  删除
Update 更新

第三步：生成网络通讯程序中使用的实体类（使用protobuf.net进行序列化)

模板生成的实体类如下：

// Author:                    msdc
// Created:                    2015-2-8
// Last Modified:            2015-2-8
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using mojoportal.Data;

namespace mojoportal.Business
{
     [ProtoContract]
    public class DepTable
    {

#region Constructors

        public DepTable()
        {}

#endregion

#region Private Properties

        private int id = -1;
        private string department = string.Empty;

#endregion

#region Public Properties

        [ProtoMember(1)]
        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        [ProtoMember(2)]
        public string Department
        {
            get { return department; }
            set { department = value; }
        }

#endregion

    }

}

模板生成的实体类 用protobuf.net序列化

第四步：用模板生成操作类

模板生成的操作类代码

模板生成的是一个基本的操作，如果我们有另外的自定义的需求，那么需要逐层添加代码。

录播教室预约系统(八)-客户端部门管理员增加教室 管理员增加完成后,其他用户就可以看到多个教室了,如图: 我们看一下客户端增加教室的代码: 添加教室:             //声明一个教室实体类             ClassRoom classRoom = == = tcpConnection.SendReceiveObject<ResMessage>(, ,  (resMessage.Message == =  + 我们看一下服务器端的处理程序 构造函数中声明: //学校管理员添加

录播教室预约系统(九)-客户端部门管理员设定教室的预约规则

录播教室预约系统(九)-客户端部门管理员设定教室的预约规则 设置预约规则的客户端代码:              int stopHourInt = (int)stopHour.Value;            int stopMinuteInt = (int)stopMinute.Value;            //截止的时间             int stopTimeInt = stopHourInt * 100 + stopMinuteInt;            //提前的

录播教室预约系统(十)-客户端部门管理员重置本单位其他人员密码

录播教室预约系统(十)-客户端部门管理员重置本单位其他人员密码 客户端代码:  //发出的数据类型为int类型  ItemID为用户对应的ID             ResMessage resMessage = tcpConnnection.SendReceiveObject<ResMessage>("ReqResetPsw", "ResResetPsw", 5000, itemID);            if (resMessage.Messa

录播教室预约系统(六)-注册新用户

预约系统中,新用户可以自己注册,然后管理员开通. 注册界面如下: 客户端新用户注册代码:       button1_Click((txtUserID.Text.Trim ()==|| txtUserName.Text.Trim ()=== ==== = newTcpConnection.SendReceiveObject<ResMessage>(, ,  (resMessage.Message ==  + 服务器端的相关处理代码: 构造函数中声明:   //注册新用户            

录播教室预约系统(二)-服务器端与数据库的交互

每个表都对应这么多类,Data类库中的类还使用了很多存储过程,如果都需要我们手工书写,会很麻烦.所以我们采用了CodeSmith模板的方法. 需要注意的是,在我们的开发过程中,模板只生成基础操作相关的一部分代码,还是会有一部分需要我们手工添加上,即使这样,模板也帮助我们做了很多工作. 模板会生成  基础数据操作部分的: (1)存储过程 (2)Data层的相关的类 每个数据表对应一个 (3)Business层相关的类  每个数据表对应两个(实体类,操作类) www.cnblogs.com/netw
