Error de linkado en vc++

[psino]

Tengo un problema y llevo varios dias comiendome la cabeza y no consigo salir de el, os explico:

Tengo una aplicacion compilada en VC++(no es MFC), quiero poder abrir y escribir cosas en un documento word. Para ello he creado un proyecto nuevo como "DLL de MFC".
En el .h de la clase donde voy a usar la funcion de la libreria le he añadido #include <stdafx.h> y #include <nombre_de_mi_dll.h> (en ese orden).
Al compilar me dan los siguientes errores:

//Y luego da un monton de warnings (si os hacen falta os los mando tambien)

ExHostAppServices y CFrameEditor son clases del proyecto donde no uso para nada la dll.

Estan los dos(proyecto y dll) en "depuracion multiproceso".

Muchas gracias por adelantado.

Y si alguien sabe otra forma de escribir en un documento word que no requiera crear una libreria aparte se lo agradeceria mucho.
