学生管理系统vc++6.0

学生管理系统是一个用于管理学生信息的软件系统。在VC++6.0中，可以使用MFC（Microsoft Foundation Classes）来开发学生管理系统。MFC是一个C++类库，它提供了一组用于创建Windows应用程序的类和函数。

下面是一个简单的学生管理系统的示例代码：

#include <afxwin.h>

class CStudent
{
public:
    CString m_strName;
    int m_nAge;
    CString m_strMajor;
};

class CStudentManagementApp : public CWinApp
{
public:
    virtual BOOL InitInstance();
};

class CStudentManagementWnd : public CFrameWnd
{
public:
    CStudentManagementWnd();

private:
    CListCtrl m_listCtrl;

    void AddStudent(const CStudent& student);

    afx_msg void OnAddStudent();
    afx_msg void OnDeleteStudent();
    afx_msg void OnEditStudent();

    DECLARE_MESSAGE_MAP()
};

BOOL CStudentManagementApp::InitInstance()
{
    CStudentManagementWnd* pMainWnd = new CStudentManagementWnd();
    m_pMainWnd = pMainWnd;
    pMainWnd->ShowWindow(SW_SHOW);
    pMainWnd->UpdateWindow();
    return TRUE;
}

CStudentManagementWnd::CStudentManagementWnd()
{
    Create(NULL, _T("学生管理系统"), WS_OVERLAPPEDWINDOW, CRect(100, 100, 500, 400));

    m_listCtrl.Create(WS_VISIBLE | WS_CHILD | LVS_REPORT, CRect(10, 10, 480, 300), this, 1);
    m_listCtrl.InsertColumn(0, _T("姓名"), LVCFMT_LEFT, 100);
    m_listCtrl.InsertColumn(1, _T("年龄"), LVCFMT_LEFT, 100);
    m_listCtrl.InsertColumn(2, _T("专业"), LVCFMT_LEFT, 200);

    CMenu* pMenu = new CMenu();
    pMenu->CreateMenu();
    pMenu->AppendMenu(MF_STRING, 1, _T("添加学生"));
    pMenu->AppendMenu(MF_STRING, 2, _T("删除学生"));
    pMenu->AppendMenu(MF_STRING, 3, _T("编辑学生"));
    SetMenu(pMenu);

    SetIcon(AfxGetApp()->LoadIcon(IDR_MAINFRAME), TRUE);
}

void CStudentManagementWnd::AddStudent(const CStudent& student)
{
    int nIndex = m_listCtrl.GetItemCount();
    m_listCtrl.InsertItem(nIndex, student.m_strName);
    m_listCtrl.SetItemText(nIndex, 1, CString(std::to_string(student.m_nAge).c_str()));
    m_listCtrl.SetItemText(nIndex, 2, student.m_strMajor);
}

void CStudentManagementWnd::OnAddStudent()
{
    CStudent student;
    student.m_strName = _T("张三");
    student.m_nAge = 20;
    student.m_strMajor = _T("计算机科学");
    AddStudent(student);
}

void CStudentManagementWnd::OnDeleteStudent()
{
    int nIndex = m_listCtrl.GetNextItem(-1, LVNI_SELECTED);
    if (nIndex != -1)
    {
        m_listCtrl.DeleteItem(nIndex);
    }
}

void CStudentManagementWnd::OnEditStudent()
{
    int nIndex = m_listCtrl.GetNextItem(-1, LVNI_SELECTED);
    if (nIndex != -1)
    {
        CStudent student;
        student.m_strName = _T("李四");
        student.m_nAge = 22;
        student.m_strMajor = _T("软件工程");
        m_listCtrl.SetItemText(nIndex, 0, student.m_strName);
        m_listCtrl.SetItemText(nIndex, 1, CString(std::to_string(student.m_nAge).c_str()));
        m_listCtrl.SetItemText(nIndex, 2, student.m_strMajor);
    }
}

BEGIN_MESSAGE_MAP(CStudentManagementWnd, CFrameWnd)
    ON_COMMAND(1, OnAddStudent)
    ON_COMMAND(2, OnDeleteStudent)
    ON_COMMAND(3, OnEditStudent)
END_MESSAGE_MAP()

CStudentManagementApp theApp;

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    if (!AfxWinInit(hInstance, hPrevInstance, lpCmdLine, nCmdShow))
    {
        return FALSE;
    }

    return theApp.Run();
}

这个示例代码创建了一个简单的学生管理系统窗口，其中包含一个列表控件用于显示学生信息。通过菜单可以添加、删除和编辑学生信息。
