使用Windows自带的记事本编写简单代码

使用Windows自带的记事本编写简单代码在如今数字化的时代，编程不再是专业程序员的专属技能，普通人也可以通过简单的工具和基础的知识来体验编程的乐趣。

Windows 自带的记事本就是这样一个容易上手的工具，它虽然看似简单，但却能帮助我们编写一些简单的代码。

首先，让我们来了解一下记事本。

记事本是 Windows 操作系统中一个基本的文本编辑工具，它没有复杂的功能和花哨的界面，只有纯粹的文字编辑区域。

但这恰恰为我们编写代码提供了一个干净、简洁的环境。

当我们决定使用记事本编写代码时，第一步就是打开它。

在Windows 系统中，您可以通过点击“开始”菜单，然后在搜索框中输入“记事本”来找到并打开它。

或者，您也可以按下快捷键“Windows ＋R”，在弹出的“运行”对话框中输入“notepad”并回车。

接下来，让我们从一个简单的 HTML 代码开始入手。

HTML（超文本标记语言）是用于创建网页的基础语言。

以下是一个简单的 HTML代码示例，用于创建一个包含标题和段落的网页：｀｀｀html＜！DOCTYPE html>＜html>＜head>＜title>我的第一个网页<／title>＜／head>＜body>＜h1>这是一个标题<／h1>＜p>这是一个段落。

＜／p>＜／body>＜／html>｀｀｀在记事本中输入上述代码后，点击“文件”菜单，选择“另存为”。

在“文件名”框中，输入“my_first_webpagehtml”（注意，一定要加上“html”扩展名，否则浏览器无法正确识别它为 HTML 文件），然后选择保存类型为“所有文件”，最后选择一个您想要保存的位置，点击“保存”。

保存完成后，找到您保存的文件，双击它，它应该会在您的默认浏览器中打开，显示出您刚刚编写的网页内容，包含一个标题和一个段落。

除了 HTML，我们还可以使用记事本编写 Python 代码。

记事本的程序设计及代码示例

记事本的程序设计及代码示例记事本是一种常见的应用程序，用于记录和编辑文本内容。

在本文中，我们将探讨记事本的程序设计，并给出一个基于Python语言的代码示例。

一、程序设计思路在设计记事本程序时，我们需要考虑以下几个方面：1. 用户界面设计：记事本的用户界面应简洁直观，方便用户输入和编辑文本内容。

可以采用菜单栏、工具栏和文本区域等组件，让用户可以进行打开、保存、复制、粘贴、查找替换等操作。

2. 功能设计：记事本应具备基本的文本编辑功能，如插入、删除、复制、粘贴和撤销等。

此外，还可以添加其他高级功能，如自动保存、自动换行、字体调整以及批量替换等。

3. 文件操作：记事本需要支持文件的打开和保存功能。

用户可以通过打开功能选择要编辑的文本文件，保存功能可以将编辑的内容保存为文件。

同时，还可以支持文件拖拽和快捷键操作。

二、代码示例下面是一个基于Python语言的记事本代码示例：```pythonimport tkinter as tkfrom tkinter import filedialogwindow = ()window.title("记事本")# 创建文本区域text_area = tk.Text(window)text_area.pack()# 打开文件函数def open_file():file_path = filedialog.askopenfilename() if file_path:with open(file_path, 'r') as file:text_area.delete(1.0, tk.END)text_area.insert(tk.END, file.read()) # 保存文件函数def save_file():file_path = filedialog.asksaveasfilename() if file_path:with open(file_path, 'w') as file:file.write(text_area.get(1.0, tk.END))menu_bar = tk.Menu(window)window.config(menu=menu_bar)# 添加文件菜单file_menu = tk.Menu(menu_bar, tearoff=False)menu_bar.add_cascade(label="文件", menu=file_menu)file_menu.add_command(label="打开", command=open_file)file_menu.add_command(label="保存", command=save_file)file_menu.add_separator()file_menu.add_command(label="退出", command=window.quit)# 运行主窗口window.mainloop()```以上代码使用Python的tkinter库创建了一个简易的记事本应用程序。

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。

记事本程序源代码汇总

记事本程序源代码汇总下面是一个简单的记事本程序的源代码：```#include <iostream>#include <fstream>#include <string>using namespace std;void showMencout << "**********************" << endl; cout << " 记事本程序 " << endl; cout << "**********************" << endl; cout << "请选择以下操作：" << endl;cout << "1. 新建记事本文件" << endl;cout << "2. 打开已有记事本文件" << endl; cout << "3. 查看记事本文件内容" << endl; cout << "4. 添加文本到记事本文件" << endl; cout << "5. 退出程序" << endl;cout << "**********************" << endl; void createFilstring filename;cout << "请输入新建记事本文件的文件名：";cin >> filename;//在当前目录创建一个新文件ofstream outFile(filename);outFile.close(;cout << "成功创建记事本文件：" << filename << endl; void openFilstring filename;cout << "请输入要打开的记事本文件的文件名：";cin >> filename;//尝试打开已存在的文件ifstream inFile(filename);if (!inFile)cout << "无法打开文件：" << filename << endl;} elsestring content;getline(inFile, content, '\0');cout << "记事本文件内容：" << endl;cout << content << endl;inFile.close(;}void viewFilstring filename;cout << "请输入要查看的记事本文件的文件名："; cin >> filename;//尝试打开已存在的文件ifstream inFile(filename);if (!inFile)cout << "无法打开文件：" << filename << endl; } elsestring line;cout << "记事本文件内容：" << endl;while (getline(inFile, line))cout << line << endl;}inFile.close(;}void appendToFilstring filename;cout << "请输入要添加文本的记事本文件的文件名：";cin >> filename;//尝试打开已存在的文件ofstream outFile(filename, ios::app);if (!outFile)cout << "无法打开文件：" << filename << endl;} elsestring content;cout << "请输入要添加的文本内容（以#结束）：" << endl; while (true)getline(cin, content);if (content == "#")break;}outFile << content << endl;}outFile.close(;cout << "成功添加文本到记事本文件：" << filename << endl; }int maiint choice;doshowMenu(;cout << "请输入您的选择：";cin >> choice;switch (choice)case 1:createFile(;break;case 2:openFile(;break;case 3:viewFile(;break;case 4:appendToFile(;break;case 5:cout << "感谢使用记事本程序，再见！" << endl;break;default:cout << "无效的选择，请重新输入！" << endl;}} while (choice != 5);return 0;```这个记事本程序通过命令行界面提供了以下操作：1.新建记事本文件：用户输入一个文件名后，在当前目录下创建一个新文件作为记事本。
