Windows.h已包含 [英] Windows.h already included

问题描述

大家好，

我正在写Win32 dll.我包括了一个可以访问数据库操作的类.我在头文件中包含了afxdb.h，并在CDatabase的头文件中声明了一个变量.

当我编译时，它给我一个 windows.h已经包含的错误. MFC应用程序不得#include< windows.h> ;;
当我尝试将其包含在.cpp文件中(在stdafx.h下面)时，它也相同，并且编译时没有错误.

Hey All,

I am writing a Win32 dll. I included a class that can access database operations. I included afxdb.h in the headerfile and declared a variable in the header file for CDatabase.

When I compile, it gives me a error that windows.h already included. MFC apps must not #include <windows.h>;
Same when I try to include it in the .cpp file (below stdafx.h) it compiles without error.

Can any one help me around this please?
