如何在 VS 2013 上运行旧的 mfc 程序？

Question

我想让这个程序在 VS 2013 上运行。放置以下内容无济于事：

#define _CRT_SECURE_NO_DEPRECATE
#define _CRT_SECURE_NO_WARNINGS
#define USE_STANDARD_FILE_FUNCTIONS

我仍然得到：

请记住，我是编程新手（大约 4 周前开始），因此请回答以下问题之一：是的，我是认真的。

有时确实需要在当前的 Visual Studio 版本上运行旧的 MBCS MFC 代码。在这种情况下，在http://msdn.microsoft.com/en-us/library/dn251007.aspx 下载 VS MBCS MFC 插件应该可以解决您的问题。
