C_实验-记事本(带源码)

C_实验-记事本(带源码)

记事本实验报告一、实验目的创建一个Windows窗体应用程序，实现记事本的基本功能，具体包括新建文件、打开文件、保存文件、查找等功能。

该实验的目的是掌握：（一）窗体程序的开发（二）常用控件的使用（三）常用事件的处理（四）对话框的设计和使用（五）文件访问的基本方法二、实验内容（一）主窗口Form1图1 主窗口主窗口界面如图1所示，功能包括基本编辑操作、主菜单和其它快捷键功能。

1、编辑功能用文本框实现。

2、窗口标题与文件名相一致。

未打开文件时为“无标题”，打开文件(另存为)后为文件名。

3、支持菜单的热键和快捷键。

二者的区别是前者是激活菜单且显示出该菜单项时有效，后者在任何时候有效。

4、实现新建、打开、保存和查找功能。

5、支持F3（查找下一个）。

用C#语言实现记事本(代码)

用C#语言实现记事本(代码)

一记事本本章介绍如何使用Visual C# 2013设计一个Windows应用程序——记事本，通过本章的学习，可以进一步掌握MenuStrip（菜单）、ToolStrip（工具栏）、RichTextBox（高级文本框）和StatusStrip（状态栏控件）等控件的使用，以及如何使用CommonDialog（公共对话框）实现对文本的存取、格式设置等操作。

(说明：所有代码必须在英文状态下使用！)1.1 记事本简介记事本是一种常用的软件，在微软的Windows中，自带了一个记事本软件，Windows 7下的记事本软件如图1所示。

图1 Windows自带的记事本本章介绍的记事本，实现了Windows自带的记事本的部分功能外，并且还可以任意更改字体的字体类型、大小和颜色，并在状态栏中显示时间。

为了方便用户的操作，还在程序的窗体上放置了一个工具栏。

本章介绍的记事本程序具有文件的新建、打开、保存功能；文字的复制、粘贴、删除功能；字体类型、格式的设置功能；查看日期时间等功能，并且用户可以根据需要显示或者隐藏工具栏和状态栏。

接下来将详细的介绍记事本程序的设计与实现的步骤和方法。

1.2 记事本界面设计新建一个Windows窗体应用程序，并命名为“Notepad”。

本节介绍记事本程序的界面设计以及界面上各控件的属性设置。

1.打开VS2013 单击文件→新建→项目2.选择模版→Visual C# →windows→windows窗体应用程序在下面的名称写Notepad出现界面如图所示3 更改窗体名称单击窗体，→右下角属性→text 修改为“记事本”如图所示控件类型控件名称属性设置结果Form Form1 Name frmNotepadText 记事本StartPosition（起始位置）CenterScreen（中央屏幕）Size 600, 450 Anchor （抛锚，使固定）（1）界面设计新建好“Notepad”项目后，定位到记事本程序的窗体设计器窗口，然后依次在窗体上放置以下控件（各1个）：（1）M enuStrip（菜单控件）。

用C编写的记事本程序

用C编写的记事本程序

最近想好好研究C，于是便拿记事本这个小程序练练手。

自己从网上找了一个挺不错的，就从这个开始学习吧。

一：代码先建立一文件夹->方便管理与查看拿我来说，在d盘根目录下新建note文件夹1.新建一note.rc资源文件，代码如下。

#include "sample.h"A ICON MOVEABLE PURE LOADONCALL DISCARDABLE "sample.ico" //LOADONCALL 调入装入MAINMENU MENU{POPUP "文件(&F)"{MENUITEM "打开(&O)...", CM_FILE_OPENMENUITEM "另存为(&S)...", CM_FILE_SAVEASMENUITEM SEPARATORMENUITEM "关闭", CM_FILE_EXIT}POPUP "帮助(&H)"{MENUITEM "关于(&A)", CM_ABOUT}}2.新建sample.h,代码如下#define CM_FILE_SAVEAS 9072#define CM_FILE_EXIT 9071#define CM_FILE_OPEN 9070#define CM_ABOUT 90693.新建源程序note.c ,代码如下#include <windows.h>#include "sample.h"static char g_szClassName[] = "MyWindowClass";static HINSTANCE g_hInst = NULL;#define IDC_MAIN_TEXT 1001BOOL LoadFile(HWND hEdit, LPSTR pszFileName){HANDLE hFile;BOOL bSuccess = FALSE;hFile = CreateFile(pszFileName, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, 0);if(hFile != INVALID_HANDLE_VALUE){DWORD dwFileSize;dwFileSize = GetFileSize(hFile, NULL);if(dwFileSize != 0xFFFFFFFF){LPSTR pszFileText;pszFileText = (LPSTR)GlobalAlloc(GPTR, dwFileSize + 1);if(pszFileText != NULL){DWORD dwRead;if(ReadFile(hFile, pszFileText, dwFileSize, &dwRead, NULL)){pszFileText[dwFileSize] = 0;if(SetWindowText(hEdit, pszFileText))bSuccess = TRUE;}GlobalFree(pszFileText);}}CloseHandle(hFile);}return bSuccess;}BOOL SaveFile(HWND hEdit, LPSTR pszFileName){HANDLE hFile;BOOL bSuccess = FALSE;hFile = CreateFile(pszFileName, GENERIC_WRITE, 0, 0,CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);if(hFile != INVALID_HANDLE_VALUE){DWORD dwTextLength;dwTextLength = GetWindowTextLength(hEdit);if(dwTextLength > 0)LPSTR pszText;pszText = (LPSTR)GlobalAlloc(GPTR, dwTextLength + 1);if(pszText != NULL){if(GetWindowText(hEdit, pszText, dwTextLength + 1)){DWORD dwWritten;if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL))bSuccess = TRUE;}GlobalFree(pszText);}}CloseHandle(hFile);}return bSuccess;}BOOL DoFileOpenSave(HWND hwnd, BOOL bSave){OPENFILENAME ofn;char szFileName[MAX_PATH];ZeroMemory(&ofn, sizeof(ofn));szFileName[0] = 0;ofn.lStructSize = sizeof(ofn);ofn.hwndOwner = hwnd;ofn.lpstrFilter = "文本文件(*.txt)\0*.txt\0所有文件(*.*)\0*.*\0\0";ofn.lpstrFile = szFileName;ofn.nMaxFile = MAX_PATH;ofn.lpstrDefExt = "txt";if(bSave){ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT;if(GetSaveFileName(&ofn))if(!SaveFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName)){MessageBox(hwnd, "保存文件失败.", "错误信息",MB_OK | MB_ICONEXCLAMATION);return FALSE;}}}else{ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;if(GetOpenFileName(&ofn)){if(!LoadFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName)){MessageBox(hwnd, "打开文件失败.", "错误信息",MB_OK | MB_ICONEXCLAMATION);return FALSE;}}}return TRUE;}LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) {switch(Message){case WM_CREATE:CreateWindow("EDIT", "",WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL | ES_MULTILINE | ES_WANTRETURN,CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,hwnd, (HMENU)IDC_MAIN_TEXT, g_hInst, NULL);SendDlgItemMessage(hwnd, IDC_MAIN_TEXT, WM_SETFONT,(WPARAM)GetStockObject(DEFAULT_GUI_FONT), MAKELPARAM(TRUE, 0));break;case WM_SIZE:if(wParam != SIZE_MINIMIZED)MoveWindow(GetDlgItem(hwnd, IDC_MAIN_TEXT), 0, 0, LOWORD(lParam),HIWORD(lParam), TRUE);break;case WM_SETFOCUS:SetFocus(GetDlgItem(hwnd, IDC_MAIN_TEXT));break;case WM_COMMAND:switch(LOWORD(wParam)){case CM_FILE_OPEN:DoFileOpenSave(hwnd, FALSE);break;case CM_FILE_SAVEAS:DoFileOpenSave(hwnd, TRUE);break;case CM_FILE_EXIT:PostMessage(hwnd, WM_CLOSE, 0, 0);break;case CM_ABOUT:MessageBox (NULL, "一个Windows C 记事本程序" , "关于...", 0);}break;case WM_CLOSE:DestroyWindow(hwnd);break;case WM_DESTROY:PostQuitMessage(0);break;default:return DefWindowProc(hwnd, Message, wParam, lParam);}return 0;}int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow){WNDCLASSEX WndClass;HWND hwnd;MSG Msg;g_hInst = hInstance;WndClass.cbSize = sizeof(WNDCLASSEX);WndClass.style = 0;WndClass.lpfnWndProc = WndProc;WndClass.cbClsExtra = 0;WndClass.cbWndExtra = 0;WndClass.hInstance = g_hInst;WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION); WndClass.hCursor = LoadCursor(NULL, IDC_ARROW); WndClass.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); WndClass.lpszMenuName = "MAINMENU";WndClass.lpszClassName = g_szClassName;WndClass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);if(!RegisterClassEx(&WndClass)){MessageBox(0, "注册窗口失败", "错误信息",MB_ICONEXCLAMATION | MB_OK | MB_SYSTEMMODAL);return 0;}hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,g_szClassName,"一个记事本程序",WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, CW_USEDEFAULT, 800, 600,NULL, NULL, g_hInst, NULL);if(hwnd == NULL){MessageBox(0, "创建窗口失败", "错误信息",MB_ICONEXCLAMATION | MB_OK | MB_SYSTEMMODAL);return 0;}ShowWindow(hwnd, nCmdShow);UpdateWindow(hwnd);while(GetMessage(&Msg, NULL, 0, 0)){TranslateMessage(&Msg);DispatchMessage(&Msg);}return Msg.wParam;}二：编译，连接运行在编译之前需要一个sample.ico图标.打开运行，输入cmd,回车，进入dos命令行进入d:\note下1.用dir命令列一下当前目录包含文件。
