my code:

class ATL_NO_VTABLE CSysLog :
.....
{
public:
[export]
enum EnumLogLevel
{
LogNone = 0,
LogError = 1,
LogWarning = 2,
LogInfo = 3,
LogDebug = 4,
LogDebug1 = 5,
LogDebug2 = 6,
LogDebug3 = 7,
LogDebug4,
};
......

it takes errors likes: c1xx : error C3174: .... LINK : fatal error LNK1250: ... how to correct it?

Um,i see ,thank you

but there's no such file ... could you leave your email,and i send the project to you ?

any example?:(,i'm too stupid

i assumed like that ,but i don't know what to do . my step: 1. crete a new atl project, maybe it named TestA. 2. Add a class "A"; 3. IA Add methods like TestErr(IErrSupport *pErr); 4. compiling... .\TestA.idl(19) : error MIDL2025 : syntax error : expecting a type specification near "IErrSupport" .\TestA.idl(19) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation 5. add import "../ErrSupport/ErrSupport.idl"; to TestA.idl ,compiling... d:\errsupport\testa\testa_i.h(69) : fatal error C1083: Cannot open include file: 'ErrSupport.h': No such file or directory

:( first sorry for my poor english.. i have an "ATL simple object" interface like "IErrSupport" , and i want to use it as a parameter like: (ISomething) DoSomething(...,IErrSupport *pErr); ... (IOtherthing) DoOtherthing(...,IErrSupport *pErr); can anybody give me an example? thanks a lot.
