‘贰’ 谁有java实现的学生信息管理系统源码
可以试试看啊

‘叁’ 求C++图书信息管理系统设计源代码
你在这发 别人是不可能给你敲出来的
其实这种系统 网上的源码太多了 你可以网络一下 然后自己修改一下 也锻炼了自己的能力了
网络文库的：http://wenku..com/view/88a74f0d844769eae009ed73.html
http://wenku..com/view/d59d8484b9d528ea81c779d3.html

‘陆’ 学生信息管理系统最简单源代码。
方法一：
1、创建一个c语言项目。然后右键头文件，创建一个Stu的头文件。
‘柒’ 分地区查询系统源码
都快毕业了还不自己好好想想啊！
‘捌’ 求一个用java写的学生成绩管理信息系统的源代码，要求有界面，能实现
以下方法实现了用户界面登陆
import java.awt.*;
import java.awt.event.*;

Button b1=new Button("登陆");//创建登陆按钮
Button b2=new Button("取消");//创建取消按钮
public DengLuJieMian()
{
this.setTitle("学生信息管理系统");//设置窗口标题
this.setLayout(null);//设置窗口布局管理器
username.setBounds(50,40,60,20);//设置姓名标签的初始位置
this.add(username);// 将姓名标签组件添加到容器

‘拾’ 微信成绩查询系统源码
现在学校最常用的查询系统生成工具是易查分,用易查分不仅可以生成成绩查询系统,还可以生成信息收集系统;各种类型的查询系统和信息收集系统在易查分基本都可以满足,在易查分生成的查询系统,还可以最大程度的自定义,实现用户的常规需求!
