记事本项目功能完善和开发

查找界面的记忆功能 、使用F3快捷键自动向下查找功能 的开发

获取选择的文字

CFileDialog 构造函数详解

   LPCTSTR lpszFileName = NULL, //指定默认文件名。如果用户没有指定文件名，则将显示此默认文件名。
   DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
   //用于指定文件对话框的标志。可以使用位操作符 | 来组合多个标志

分页模式开发

MainDlg.h: 头文件

#pragma once
#include "CPage1.h"
#include "CPage2.h"
#include "CPage3.h"
class CMainDlg : public CDialogEx
{
// 构造
	CPage1 m_p1;

};

MainDlg.cpp: 实现文件
创建标签，将三个分页创建在这里面进行显示

BOOL CMainDlg::OnInitDialog()
{
	CDialogEx::OnInitDialog();
	
	m_tab.InsertItem(0, _T("基础信息"));
	m_tab.InsertItem(1, _T("联系信息"));
	m_tab.InsertItem(2, _T("其他信息"));
	
	m_p1.Create(IDD_PAGE1, &m_tab);//把三个分页创建在这里面 父子关系 Create 一个对象只能创建一次
	m_p2.Create(IDD_PAGE2, &m_tab);	
	m_p3.Create(IDD_PAGE3, &m_tab);
	
	m_p1.ShowWindow(SW_SHOW);	
	m_p2.ShowWindow(SW_SHOW);	
	m_p3.ShowWindow(SW_SHOW);
	
	CRect rect, rc;
	m_tab.GetClientRect(rect); //将分页窗口的位置向下平移了 要不然回覆盖掉原窗口
	m_tab.GetItemRect(0, rc);	
	rect.top = rc.bottom;
	m_p1.MoveWindow(rect);		
	m_p2.MoveWindow(rect);		
	m_p3.MoveWindow(rect);
	return TRUE;  // 除非将焦点设置到控件，否则返回 TRUE
}

当选择不同的标签时对不同的窗口进行隐藏或者显示

void CMainDlg::OnSelchangeTab(NMHDR* pNMHDR, LRESULT* pResult)
{
	*pResult = 0;
	int nIndex = m_tab.GetCurSel();
	int nCount = m_tab.GetItemCount();
	CWnd* ps[] = { &m_p1,&m_p2,&m_p3 };
	int i = -1;
	while (++i<nCount)
	{
		if (nIndex == i) 
			ps[i]->ShowWindow(SW_SHOW);
		else
			ps[i]->ShowWindow(SW_HIDE);

	}
}

实际效果：
