MS Project 2013 - Automatically use a shared resources file

Hello,

i want to do these actions each time a .mpp is open:

1. Open a localy shared resources files
2. Force the opened projet to use this shared resources files 

I already have the point 1

    Set Mpp = New MSProject.Application

    Mpp.FileOpenEx Name:="C:\Ressources.mpp", ReadOnly:=True, openPool:=PjPoolOpen.pjPoolReadOnly

But i do not know how to make the opened file automatically use this shared resources files.

Is someone can help me ?

Thanks

Sébastien
