编译提示错误：:\练习\dd\debug\msado15.tlh(407) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
f:\练习\dd\stdafx.h(32) : fatal error C1070: mismatched #if/#endif pair in file 'f:\练习\dd\stdafx.h'
Error executing cl.exe.

dd.exe - 1 error(s), 1 warning(s)
请问该怎么解决？？
还是不行，加了错误更多了

Answer 1

1）warning C4146: unary minus operator applied to unsigned type, result still unsigned
这个警告可以忽略，不影响。
2）fatal error C1070: mismatched #if/#endif pair in file 'f:\练习\dd\stdafx.h'
这是因为你缺少了一个endif。
在：
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h> // MFC support for Windows Common Controls
之后价格#endif。
即：
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h> // MFC support for Windows Common Controls
#endif

补充：错误更多，并不是说刚才那个改错了，而是其他地方的错误吧。
