C#公司员工管理系统实训报告.doc

网络协议编程设计C#实训课程项目报告公司管理系统，自己做的，除了数据库不能发其他源代码都有（实训设计）一、实训题目：公司员工管理系统二、实训意义：通过此次实训，让我们进一步了解c#应用程序开发的过程，同时也让我们对前面所学的知识付出实践，达到熟练掌握、综合性应用的目的。三、实训内容：1、项目分析：1)员工信息管理 2)员工考勤管理2、项目设计首先，我们必须建立一个登录系统和八个子系统。登录系统：用户在登陆后可以进行权限操作管理。员工信息管理系统：对员工信息进行查询、修改、添加、删除。员工考勤管理系统：对员工考勤信息进行查询、修改、添加、删除。使用SQL SERVER2005建立YGGL数据库，其中包括：用户表员工信息表员工考勤表四、项目的实现1、使用SQL2005创建YGGL数据库。2、分别在SQL2005的YGGL数据库下创建admin表、employee_info表、attendance表，其代表用户表、员工信息表、员工考勤表。1) 用户信息表：CREATE TABLE dbo.admin( name varchar(50) COLLATE Chinese_PRC_CI_AS NOT NULL, pwd varchar(50) COLLATE Chinese_PRC_CI_AS NOT NULL) ON PRIMARYGO2) 员工信息表CREATE TABLE dbo.employee_info( userid int NOT NULL, name char(10) COLLATE Chinese_PRC_CI_AS NOT NULL, sex char(10) COLLATE Chinese_PRC_CI_AS NOT NULL, workyear varchar(2) COLLATE Chinese_PRC_CI_AS NULL, phone varchar(50) COLLATE Chinese_PRC_CI_AS NULL, addr varchar(50) COLLATE Chinese_PRC_CI_AS NULL, CONSTRAINT PK_employee info PRIMARY KEY CLUSTERED ( userid ASC)WITH (IGNORE_DUP_KEY = OFF) ON PRIMARY) ON PRIMARYGO2) 员工考勤表CREATE TABLE dbo.attendance( userid int NOT NULL, leave int NULL, travel int NULL, absent int NULL, CONSTRAINT PK_attendance PRIMARY KEY CLUSTERED ( userid ASC)WITH (IGNORE_DUP_KEY = OFF) ON PRIMARY) ON PRIMARY3、使用C#进行窗口设计（源代码）1)登录系统：private void btnloginOK_Click_1(object sender, EventArgs e) SqlConnection dbConnection = new SqlConnection(server=.;database=YGGL;uid=sa;pwd=); SqlDataReader dataReader; string sqlString = SELECT name,pwd FROM admin; string loginPassWord = ; dbConnection.Open(); SqlCommand dbCommand = new SqlCommand(sqlString, dbConnection); dataReader = dbCommand.ExecuteReader(); try if (dataReader.HasRows) dataReader.Read(); LoginName = dataReadername.ToString(); loginPassWord = dataReaderpwd.ToString(); catch (Exception e1) MessageBox.Show(e1.Message, 登陆出错); dataReader.Close(); if (LoginName = textBox1.Text & loginPassWord = textBox2.Text) this.Hide(); Main frm1 = new Main(); frm1.ShowDialog(); else MessageBox.Show(请输入正确的用户名或者密码！, 登陆出错); LoginName = null; 2)员工信息查询系统：查询：private void btnDemand_Click(object sender, EventArgs e) conn = new SqlConnection(server=.;database=YGGL;uid=sa;pwd=); if (rdbid.Checked = true) sda = new SqlDataAdapter(select * from employee_info where userid=+textChecked.Text.Trim()+, conn); ds = new DataSet(); sda.Fill(ds,employee_info); if (rdbname.Checked = true) sda = new SqlDataAdapter(select * from employee_info where name= + textChecked.Text.Trim() + , conn); ds = new DataSet(); sda.Fill(ds, employee_info); else dataGridView1.DataSource = ds.Tables0; 3)员工考勤管理系统：查询：private void btnDemand1_Click(object sender, EventArgs e) conn = new SqlConnection(server=.;database=YGGL;uid=sa;pwd=); sda = new SqlDataAdapter(select * from attendance where userid= + textChecked1.Text.Trim() + , conn); ds = new DataSet(); sda.Fill(ds, attendance); dataGridView2.DataSource = ds.Tables0; 修改：private void btnDemand2_Click(object sender, EventArgs e) conn = new SqlConnection(server=.;database=YGGL;uid=sa;pwd=); sda = new SqlDataAdapter(update attendance set leave= + textleave.Text.Trim() + ,travel= + texttravel.Text.Trim() + , absent= + textabsent.Text.Trim() + where userid= + textChecked1.Text.Trim() + , conn); ds = new DataSet(); sda.Fill(ds, attendance); 4)新窗体：添加窗体：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Data.SqlClient;namespace WindowsApplication1 public partial class insert : Form public insert() InitializeComponent();
