冲刺阶段 day 6

项目进展：学生管理这部分已经进展的差不多了，调试了几遍,改了几个小Bug之后就没有什么问题了,基本完成，如若后续还有一些新的功能到时候再自行加入。明天开始教师部分。

存在问题：我觉得我们的项目还是比较课堂，比较中规中矩的，还需一些闪光点来加分，例如再加入一些功能。下次小组开会的时候再讨论一下。

实现的部分代码：

MainFrm

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace GengdanContactsMIS_WinForm

{

    public partial class MainFrm : Form

    {

        public MainFrm()

        {

            InitializeComponent();

        }

        private void 系部管理ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            DepartmentFrm f = new DepartmentFrm();

            f.ShowDialog();

        }

        private void 专业管理ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            MajorFrm m = new MajorFrm();

            m.ShowDialog();

        }

        private void btnCancel_Click(object sender, EventArgs e)

        {

            this.Close();

        }

        private void 班级管理ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            ClassFrm f = new ClassFrm();

            f.ShowDialog();

        }

        private void 学生管理ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            StudentFrm f = new StudentFrm();

            f.ShowDialog();

        }

        private void 教师管理ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            TeacherFrm f = new TeacherFrm();

            f.ShowDialog();

        }

    }

}

            BindStudent();

        }

        void BindClass()

        {

            string sql = "select ClassId ,ClassName from Class";

            DB db = new DB();

            DataSet ds = db.GetDataSet(sql, "Class");

            cbClass.DataSource = ds.Tables["Class"];

            cbClass.DisplayMember = "ClassName";

            cbClass.ValueMember = "ClassId";

        }

        void BindStudent()

        {

            string sql = "select SNo as 学号,SName as 姓名,Sex as 性别,ClassName as 班级,BirthDate as 出生年月日,Phone as 电话,Email as 邮箱,Adress as 地址 from Student,Class where Student.ClassId=Class.ClassId";

            DB db = new DB();

            DataSet ds = db.GetDataSet(sql,"Student");

            dataGridView1.DataSource = ds.Tables["Student"];

        }

        private void btnAdd_Click(object sender, EventArgs e)

        {

            string sql = "insert into Student(SNo,SName,Sex,ClassId,BirthDate,Phone,Email,Adress)values("

                 + txtSNo.Text + ",'" + txtSName.Text + "','" + txtSex.Text + "'," + cbClass.SelectedValue + ",'" + txtBirthDate.Text + "','" + txtPhone.Text + "','" + txtEmail.Text + "','" + txtAdress.Text + "')";

             DB db = new DB();

             if (db.ExecuteSQL(sql))

                 MessageBox.Show("学生增加成功");

             else

                 MessageBox.Show("学生增加失败，请检查学号是否已存在");

             BindStudent();

        }

        private void btnSearch_Click(object sender, EventArgs e)

        {

            string sql = "select SNo,SName,Sex,ClassName,BirthDate,Phone,Email,Adress from Class,Student where Class.ClassId=Student.ClassId and SName='" + txtSName.Text + "'";

            DB db = new DB();

            DataSet ds = db.GetDataSet(sql, "a");

            dataGridView1.DataSource = ds.Tables["a"];

        }

        private void btnCancel_Click(object sender, EventArgs e)

        {

            this.Close();

        }

    }

}
