1、简介

ActiveX 控件是允许网站提供视频和游戏等内容的小应用。浏览 Web 时，你也可以使用这些小应用与工具栏和股票代码等内容进行交互。但是，这些应用有时可能出现问题，或者向你提供不需要的内容。在某些情况下，这些应用可以用来从你的电脑收集信息、破坏电脑上的信息、在未获得你同意的情况下在你的电脑上安装软件或允许其他人远程控制你的电脑。

2、代码编写

打开VS2017，新建一个MFC ActiveX控件工程，如下图所示：

（1）FxActiveXMfcGLFont.idl，在里面定义接口和事件。

// FxActiveX_MfcGLFont.idl : ActiveX 控件项目的类型库源。

// 此文件将由 MIDL 编译器工具处理以
