向 MFC 项目添加 #include 时的警告 C4995 <vector>

Warnings C4995 when adding #include <vector> to MFC project

我正在尝试将#include <vector>添加到我的MFC项目中。它编译了，但我收到了以下警告（只是其中的一些，实际列表要长得多）：

1>c:program files (x86)microsoft visual studio 9.0vcincludecstdio(49) : warning C4995: 'gets': name was marked as #pragma deprecated
1>c:program files (x86)microsoft visual studio 9.0vcincludecstdio(53) : warning C4995: 'sprintf': name was marked as #pragma deprecated
1>c:program files (x86)microsoft visual studio 9.0vcincludecstdio(56) : warning C4995: 'vsprintf': name was marked as #pragma deprecated
1>c:program files (x86)microsoft visual studio 9.0vcincludecstring(22) : warning C4995: 'strcat': name was marked as #pragma deprecated

1>c:program files (x86)microsoft visual studio 9.0vcincludecwchar(41) : warning C4995: 'wcscpy': name was marked as #pragma deprecated

我可以这样做让它静音：

#pragma warning(push)
#pragma warning(disable: 4995)
#include <vector>
#pragma warning(pop)

但我很好奇为什么图书馆会发出这些警告？如果有比抑制警告更好的方法来解决这个问题呢？

此警告表示已标记为过时的函数，将来的版本可能不再支持该函数。

因此，您可以有两种方法来处理它：第一种是使用方式，用pragma deprecated标记它，或者您可以使用它们的安全版本。

例如，Strcpy有一个名为StringCchCopy/StringCbCopy的相应函数，而get有get_s。你可以从MSDN中找到它们。

祝你好运。：）
