I have an MFC based dll that only exports some classes. I need to ask where
should i place this macro (AFX_MANAGE_STATE) in the class, do i really need
it?

You need this if your dll is a Regular DLL. If you have a MFC Extension
DLL, you should not use this Macro.

In a regular DLL this really has nothing to do with exporting but
rather with changing the state to the one used in the function. For
example, resources used in the function may want to refer to
application or for the dll itself. You will then change the state using
AFX_MANAGE_STATE. State also has relevance when you call methods like
AfxGetMainWnd. In a regular DLL, if your method wants to access main
frame window, you will need to use
AFX_MANAGE_STATE(AfxGetAppModuleState()).
