引入ado出现《windows.h》already包含了怎么办？
我新建一个工程多文档不包含数据库。下面导入#import "c:\Program Files\Common Files\System\ado\msado15.dll " no_namespace rename( "EOF ", "rsEOF ")但出现如下错误
warning C4146: unary minus operator applied to unsigned type, result still unsigned
fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>
我用基本对话框，单文档都是了还是一样
我把stdafx。h里面的include "windows.h "删除掉还是一样的
怎么回事啊？



[解决办法]
顺序换一下。。
