学生学籍管理系统的设计与实现

private void btnLeftAll_Click(object sender, EventArgs e) {

this.BindingContext[ds, \ btnLeftAll.Enabled = false; btnLeft.Enabled = false; btnRight.Enabled = true; btnRightAll.Enabled = true; }

private void btnLeft_Click(object sender, EventArgs e) {

if (this.BindingContext[ds, \ {

this.BindingContext[ds, \

if (this.BindingContext[ds, \ {

btnLeftAll.Enabled = false; btnLeft.Enabled = false; }

btnRight.Enabled = true; btnRightAll.Enabled = true; } }

private void btnRight_Click(object sender, EventArgs e) {

if (this.BindingContext[ds, \< this.BindingContext[ds, \

{

this.BindingContext[ds, \

if (this.BindingContext[ds, \== this.BindingContext[ds, \

{

btnRight.Enabled = false; btnRightAll.Enabled = false; }

btnLeft.Enabled = true; btnLeftAll.Enabled = true;

} }

private void btnRightAll_Click(object sender, EventArgs e) {

this.BindingContext[ds, \this.BindingContext[ds, \

btnLeft.Enabled = true; btnLeftAll.Enabled = true; btnRight.Enabled = false; btnRightAll.Enabled = false; }

private void btnDelete_Click(object sender, EventArgs e) {

=

//删除学生账户信息

int i= this.BindingContext[ds, \

string Num = ds.Tables[\ string sql = \from T_Student_user where Num='\+ Num + \

bool flag = dataOperate.execSQL(sql); if (flag) {

//删除T_Student表中的数据

sql = \ bool flag1 = dataOperate.execSQL(sql); if (flag1) {

MessageBox.Show(\删除成功!\ getInfo(); } else {

MessageBox.Show(\删除用户信息失败!\ return; } //int rowID = this.BindingContext[ds, \

//ds.Tables[\

21 / 55

//sdapt.Update(ds, \

//this.BindingContext[ds, \ //btnLeft.Enabled = false; //btnLeftAll.Enabled = false; //btnRight.Enabled = true; //btnRightAll.Enabled = true; } else {

MessageBox.Show(\删除用户账户失败!\ return; } }

private void btnClose_Click(object sender, EventArgs e) {

this.Close(); }

private void cbDepartment_SelectedIndexChanged(object sender, EventArgs e)

{

string sql = \mr.majorName from T_Major as mr,T_Department as dt where dt.departmentName='\+ cbDepartment.Text + \and mr.departmentID=dt.departmentID\

ds1 = dataOperate.getDataSet(sql, \ cbMajor.DataSource = ds1.Tables[0];

cbMajor.DisplayMember = \ }

private void cbMajor_SelectedIndexChanged(object sender, EventArgs e)

{

string sql = \mr where mr.majorName='\

ds1 = dataOperate.getDataSet(sql, \ cbClass.DataSource = ds1.Tables[0]; cbClass.DisplayMember = \ }

private void cbClass_SelectedIndexChanged(object sender, EventArgs e)

{

getInfo(); }

public void getInfo() {

con = dataOperate.createConnection(); con.Open();

string sql = \学号',st.Name as '姓名',st.Sex as '性别',st.Birthday as '出生',st.Address as '籍贯' from T_Student as st,T_Class as cs where cs.className='\

sdapt = new SqlDataAdapter(sql, con); ds = new DataSet();

sdapt.Fill(ds, \

dataGridView1.DataSource = ds;

dataGridView1.DataMember = \ dataGridView1.ReadOnly = true; } (五)

学生信息录入界面设计

其窗口界面如下图:

23 / 55

这里只能对学生进行添加,即身份只能选择Student。

实现代码如下:

private static string sql = \

public static string Num = \ public static string Name = \

private void cbShenFen_SelectedIndexChanged(object sender, EventArgs e)

{

Num = txtNum.Text;

Name = txtUserName.Text;

switch (cbShenFen.SelectedIndex) {

case 0: sql = \* from T_Administrator_user where Num='\

case 1: sql = \+ Num + \

case 2: sql = \+ Num + \

}

bool flag = dataOperate.seleSQL(sql); if (flag) {
