动态链接库连接数据库问题
我做了一个动态链接库想通过ADO调用数据库，当我把#import "c:\program files\common files\system\ado\msado15.dll " \
no_namespace \
rename ( "EOF ", "adoEOF ")加入到stdafx.h后编译出现错误：
e:\servicecomment\debug\msado15.tlh(171) : error C2011: 'LockTypeEnum ' : 'enum ' type redefinition
e:\servicecomment\debug\msado15.tlh(214) : error C2011: 'DataTypeEnum ' : 'enum ' type redefinition
e:\servicecomment\debug\msado15.tlh(258) : error C2011: 'FieldAttributeEnum ' : 'enum ' type redefinition
e:\servicecomment\debug\msado15.tlh(279) : error C2011: 'EditModeEnum ' : 'enum ' type redefinition
e:\servicecomment\debug\msado15.tlh(287) : error C2011: 'RecordStatusEnum ' : 'enum ' type redefinition
e:\servicecomment\debug\msado15.tlh(407) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
e:\servicecomment\debug\msado15.tlh(530) : error C2011: 'ParameterDirectionEnum ' : 'enum ' type redefinition
这是什么原因？
[解决办法]
#import "msado15.dll " no_namespace \
rename( "EOF ", "EndOfFile ") \
rename( "LockTypeEnum ", "newLockTypeEnum ") \
rename( "DataTypeEnum ", "newDataTypeEnum ") \
rename( "FieldAttributeEnum ", "newFieldAttributeEnum ") \
rename( "EditModeEnum ", "newEditModeEnum ") \
rename( "RecordStatusEnum ", "newRecordStatusEnum ") \
rename( "ParameterDirectionEnum ", "newParameterDirectionEnum ")
