结合本科C++项目的MFC学习总结

个人财务管理软件设计中MFC控件的使用(List）

1.添加内容

//将添加的信息在列表中显示
	CString sName, sDate, sPlace, sSalary, sBonus, sAlimony;
	ifstream addfin("adduse.txt", ios::in);
	string a1, a2, a3, a4, a5, a6;
	while(addfin >> a1>> a2 >> a3 >> a4 >> a5 >> a6)
	{
   
   
	sName=a1.c_str();
	sDate = a2.c_str();
	sPlace = a3.c_str();
	sSalary = a4.c_str();
	sBonus = a5.c_str();
	sAlimony = a6.c_str();
	myList1.InsertItem(0, NULL);//插入一个行
	myList1.SetItemText(0, 0, sName);//填充数据
	myList1.SetItemText(0, 1, sDate);
	myList1.SetItemText(0, 2, sPlace);
	myList1.SetItemText(0, 3, sSalary);
	myList1.SetItemText(0, 4, sBonus);
	myList1.SetItemText(0, 5, sAlimony);
	}

2.删除内容

//判断列表框中是否有记录
	if (!myList1.GetItemCount())	{
   
   
		MessageBox(L"暂无记录", L"警告",  MB_OKCANCEL | MB_ICONEXCLAMATION);
		return;
	}
	//判断是否选中一项，若选中则删除
	POSITION ps;
	int index = 0;
	ps = myList1.GetFirstSelectedItemPosition();
	index = myList1.GetNextSelectedItem(ps);//标记行号
	if (-1 == index)
	{
   
   
		MessageBox(L"请选中一行数据", L"警告", MB_OKCANCEL | MB_ICONEXCLAMATION);
		return;
	}
	else
	{
   
   
		if (IDOK == MessageBox(L"确定删除？", L"提示", MB_OKCANCEL | MB_ICONQUESTION))
		{
   
   
			myList1.DeleteItem(index);
		}
	}

3.修改内容

// 删除再添加

4.查询内容

CString str, cbsel;
	int nIndex = myCombo.GetCurSel();
	myCombo.GetLBText(nIndex, str);
	GetDlgItemText(IDC_CBSEL, cbsel);
	UpdateData(TRUE);
	int i,flag = 0;
	if (str == "姓名")
	{
   
   
		for (i = 0; i<myList1.GetItemCount(); ++i)
		{
   
   
			if (cbsel == myList1.GetItemText(i, 0))
			{
   
   
				myList2.InsertItem(0, NULL);
				myList2.<
