MFC捐款管理系统
程序的运行：
首先来看登录界面：
这个登录界面对应ManageSystemDlg类,在ManageSystemDlg.cpp中主要就是一个登录的逻辑代码，如果用户名和密码输入正确当前主窗口隐藏，子窗口弹出，子窗口SysytemDig就是程序的主界面类：
关键代码：
void CManageSystemDlg::OnBnClickedButtonLgn()
{
// TODO: Add your control notification handler code here
CString sun, spwd;
GetDlgItemText(IDC_EDIT_UNAME, sun);
GetDlgItemText(IDC_EDIT_PWD, spwd);
//登录的条件
BOOL isSuccess = !sun.CollateNoCase(_T("admin")) && !spwd.CollateNoCase(_T("123456"));
//isSuccess = true;
if (isSuccess){
//当前的主窗口隐藏 子窗口出现
ShowWindow(SW_HIDE);
//创建一个对话框
SystemDig dig;
//弹出来
dig.DoModal();
}else{
MessageBox(_T("用户名或密码不正确"),_T("登陆失败"));
}
}
接下来就是程序的主界面类：SystemDig
SystemDig.h代码：
#pragma once
#include "afxcmn.h"
// SystemDig dialog
class SystemDig : public CDialogEx
{
DECLARE_DYNAMIC(SystemDig)
public:
SystemDig(CWnd* pParent = NULL); // standard constructor
virtual ~SystemDig();
// Dialog Data
#ifdef AFX_DESIGN_TIME
enum {
IDD = IDD_DIALOG1 };
#endif
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
DECLARE_MESSAGE_MAP()
public:
afx_msg void OnClose();
virtual BOOL OnInitDialog();
// 这是显示捐款收据的列表
CListCtrl m_List;
afx_msg void OnBnClickedButton1();
afx_msg void OnBnClickedButtonReverse();
afx_msg void OnBnClickedButton3();
afx_msg void OnBnClickedButton4();
afx_msg void OnBnClickedButton5();
afx_msg void OnBnClickedButtonSave();
afx_msg void OnBnClickedButtonOpen();
afx_msg void OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult);
};
他的设计界面如下：
SystemDig.cpp：
// SystemDig.cpp : implementation file
//
#include "stdafx.h"
#include "ManageSystem.h"
#include "SystemDig.h"
#include "afxdialogex.h"
#include "PropertyDlg.h"
// SystemDig dialog
IMPLEMENT_DYNAMIC(SystemDig, CDialogEx)

{
}

{
}
void SystemDig::DoDataExchange(CDataExchange* pDX)
{

DDX_Control(pDX, IDC_LIST1, m_List);
}

END_MESSAGE_MAP()
// SystemDig message handlers
//窗口关闭时执行
void SystemDig::OnClose()
{

//创建行

}
//全选

}
}

}
//右击事件添加的事件处理
void SystemDig::OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult)

int i=pNMItemActivate->iItem;
PropertyDlg dig;
dig.DoModal();
m_List.SetItemText(i,0,dig.sType);
m_List.SetItemText(i,1,dig.sDate);
m_List.SetItemText(i,2,dig.sMoney);
}
这个其中有一个PropertyDlg类，他就是为了修改的，界面如下：
PropertyDlg.h:
#pragma once
// PropertyDlg dialog
class PropertyDlg : public CDialogEx
{
DECLARE_DYNAMIC(PropertyDlg)
public:
PropertyDlg(CWnd* pParent = NULL); // standard constructor
virtual ~PropertyDlg();
// Dialog Data
#ifdef AFX_DESIGN_TIME
enum {
IDD = IDD_DIALOG2 };
#endif
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
DECLARE_MESSAGE_MAP()
public:
//创建对象
CString sType;
CString sDate;
CString sMoney;
afx_msg void OnBnClickedButtonOk();
};
PropertyDlg.cpp:
// PropertyDlg.cpp : implementation file
//
#include "stdafx.h"
#include "ManageSystem.h"
#include "PropertyDlg.h"
#include "afxdialogex.h"
// PropertyDlg dialog
IMPLEMENT_DYNAMIC(PropertyDlg, CDialogEx)
PropertyDlg::PropertyDlg(CWnd* pParent /*=NULL*/)
: CDialogEx(IDD_DIALOG2, pParent)
{
}
PropertyDlg::~PropertyDlg()
{
}
void PropertyDlg::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);
}
BEGIN_MESSAGE_MAP(PropertyDlg, CDialogEx)
ON_BN_CLICKED(IDC_BUTTON_OK, &PropertyDlg::OnBnClickedButtonOk)
END_MESSAGE_MAP()
// PropertyDlg message handlers
//确定
void PropertyDlg::OnBnClickedButtonOk()
{
// TODO: Add your control notification handler code here
GetDlgItemText(IDC_EDIT_TYPE,sType);
GetDlgItemText(IDC_EDIT_DATE, sDate);
GetDlgItemText(IDC_EDIT_MONEY, sMoney);
EndDialog(0);
}
这个是一个比较简单的项目，但对于新手往往看不懂MFC框架的知识点，我推荐大家还是先去看看Windows api的知识，再来学习MFC就比较容易了，另外给大家推荐一本书作者好像叫孙鑫，书名叫VC++深入好像，我感觉这是本对初学者作用十分大的书，纯小白可能看不懂
