cannot open source file "stdafx.h"
提问by Jake
I have two include file headers
我有两个包含文件头
#include "stdafx.h"
#include "psapi.h"
However it gives a cannot open source file "stdafx.h" compile time error. I am using Visual Studios 2010. Is "stdafx.h" even necessary? I think so because the program cannot compile if i take it away.
但是它给出了一个无法打开源文件“stdafx.h”的编译时错误。我正在使用 Visual Studios 2010。甚至需要“stdafx.h”吗？我这么认为是因为如果我把它拿走，程序就无法编译。

Visual Studio uses it for "precompiled headers" feature. If you are not experienced with Visual Studio, I would recommend to keep the stdafx.h in the project.
Visual Studio 将其用于“预编译头”功能。如果您对 Visual Studio 没有经验，我建议您将 stdafx.h 保留在项目中。
And of course, if you #include it, you ought to have it.
当然，如果你 #include 它，你应该拥有它。

stdafx.h is used for precompiled headers. It is not necessary, but disabling the compiler feature can be a little tricky if you have never done it before. If you have it, then you must compile 'stdafx.cpp' before compiling anything else.
stdafx.h 用于预编译头文件。这不是必需的，但如果您以前从未这样做过，禁用编译器功能可能会有点棘手。如果你有它，那么你必须在编译其他任何东西之前编译'stdafx.cpp'。
