Visual Studio 无法识别我的网络摄像头激光测距仪代码的 MFC 库

我尝试直接从互联网复制源代码，但由于下面发现的错误，我无法构建/调试整个文件。

请帮忙

Question: 我去哪里”将项目属性更改为 Unicode"?

Answer :

对于 C++ 来说，

右键单击项目，然后选择属性（或 Alt-Enter ）属性页应该打开

Under 配置属性

General

[-]项目默认值

  **Character Set** : Use Multi-Byte Character Set

- 改成 -

  **Character Set** : Use Unicode Character Set

找到它就痛不欲生。
