Excuse me, but how do you access a file (in my case excel) that is in the resources folder? I am using interop to access to all of my excel files, any ideas how to access them via the resources folder?

Code:
' what i have:
xlsWorkBook = xlsApp.Workbooks.Open("C:\inventario Programa Julio.xlsx")

'is this right?
xlsWorkBook = xlsApp.Workbooks.Open(Str(My.Resources.acceso))
