问ado导入
我在stdAfx.h中加入#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename("EOF","EndofFile")
就出现错误
Compiling...
StdAfx.cpp
g:\download\database\debug\msado15.tlh(403) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
d:\microsoft visual studio\vc98\mfc\include\afxv_w32.h(14) : fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>
Error executing cl.exe.
是什么原因?
