I moved some modules to a library, built an .mde, and made a reference in Tools - References. When the database is open, the library also opens, and I see a library.ldb file. I was thinking that there would be a way to make it readonly and therefore faster, since there is nothing but code in the library file and no need for record locking. It is just a code library. There is no wizard or builder. Am I even doing it the right way?
