Hello, I'm writing a simple console application using Visual Studio 2008 pro. I need to connect to an Access database, so i decided to use MFC libraries. I included afxdb.h, but when i compile my application, i get the following errors: d:\programmi\microsoft visual studio 9.0\vc\atlmfc\include\afxdb.h(318) : error C2248: 'CObject::CObject': unable to access to private member declared in class 'CObject' d:\programmi\microsoft visual studio 9.0\vc\atlmfc\include\afxdb.h(957) : error C2248: 'CObject::CObject': unable to access to private member declared in class 'CObject' I found on google something about problems with afxdb.h using Unicode. I checked all my project configuration and i removed the only reference to Unicode that i found, precisely i set the character set to "undefined". I hope someone can give me an hint.. thank you in advice
