描述:
我在OCX中调用msado15.dll模块，在StdAfx.h中调用如下；
#import "bin\msado15.dll" no_namespace rename("EOF","adoEOF")
结果编译时系统报错如下：
d:\vc\myocx\debug\msado15.tlh(171) : error C2011: 'LockTypeEnum' : 'enum' type redefinition
d:\vc\myocx\debug\msado15.tlh(214) : error C2011: 'DataTypeEnum' : 'enum' type redefinition

Error executing cl.exe.
MyOCX.ocx - 6 error(s), 1 warning(s)
可是我在程序中并没有找到这些enum类型在其他地方有定义。不知道这是出了什么问题？急切请教高手们。
