VC大作业报告(学生信息管理系统)

高级程序设计项目训练报告指导教师：黄欢时间 2012 年 7 月 27 日专业年级:姓名：学号： 报告分程序功能：1) 学生基本信息录入功能 2) 学生信息查询功能 3） 学生信息的删除学生信息包括：姓名、性别、学号、班级、出生年月、手机号码、已经获得学分等输入输出数据的说明：输入学生信息点击确定，在“学生信息查询”中输入姓名，就可以在“查询结果”中输出相应信息。报告内容一、 分析设计的是一个基于MFC对话框的C+应用程序，创建了一个主对话框，和一些必要的子对话框。在主对话框中添加列表控件用来显示学生的基本信息。主要用到了在MFC中运用编辑框的只是，还有插入位图。二、 操作运行后点击“学生信息录入”显示： 输入相关信息在确定。在选中信息点击删除，可进行删除操作。点击“学生信息查询”显示：输入名字，若有信息储存，则在查询结果中显示，若无信息储存则显示：主代码：/ zxyDlg.cpp : implementation file/#include stdafx.h#include zxy.h#include zxyDlg.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CZxyDlg dialogCZxyDlg:CZxyDlg(CWnd* pParent /*=NULL*/): CDialog(CZxyDlg:IDD, pParent)/AFX_DATA_INIT(CZxyDlg)/ NOTE: the ClassWizard will add member initialization here/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CZxyDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CZxyDlg)DDX_Control(pDX, IDC_BUTTON3, m_button_change);DDX_Control(pDX, IDC_BUTTON2, m_button_del);DDX_Control(pDX, IDC_BUTTON1, m_button_enter);DDX_Control(pDX, IDC_LIST4, m_list_ctrl);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CZxyDlg, CDialog)/AFX_MSG_MAP(CZxyDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(IDC_BUTTON1, OnButton1)ON_BN_CLICKED(IDC_BUTTON2, OnButton2)ON_BN_CLICKED(IDC_BUTTON3, OnButton3)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CZxyDlg message handlersBOOL CZxyDlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
