VS编写的记事本源码

记事本源代码先上效果图。

这个记事本操作简便，功能强⼤，在记事本的基础上添加了将内容发送短信和发送邮件的功能。

这个应⽤也已经功过了微软的认证。

115⽹盘⾥⾯的是最新的。

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。
