MFC控件使用自己本地的字体文件

MFC作为一套古老的框架，加载使用本地字体流程也很复杂，网上的资料大多也都不能直接运行。在参考了一些github上现有代码和古代代码之后，实现了加载本地字体文件并显示在指定控件的功能。

首先要把字体文件加载到资源文件里，资源视图下右键-添加资源, 点击自定义，输入"OTF", "TTF"等需要加载的字体文件类型，记得要加双引号。

然后点击导入，将需要加载的字体文件导入到相应的资源里：

资源导入完成后开始加代码：

CFontHelper.h

#pragma once

#include

using namespace Gdiplus;

class CFontHelper

{

public:

CFontHelper();

~CFontHelper();

public:

大功告成，使用的时候只要这样：
