Unable to use extension in Visual Studio project

I am trying to use the EditBox extension in Visual Studio, but its giving me compilation and linker errors. I have opened the visual studio solution in cocos2dx folder and have add a new project to the solution. And I am referencing all the libcocos2dx, libbox2d and libextension in “Common Properties” / “Frameworks and references” . Still its giving me errors. Has anyone faced this issue? Am I doing something the wrong way?

i will try use editbox but have the same error, if you found something I would greatly appreciate it. sorry for my poor english skills.
