[AccessD] Create a .lib library for use with Access

Sun Mar 26 10:47:08 CDT 2023

For many years with four customers I used a .mdb or .mde as a reference library file.  The systems ran just fine with no evidence of slowdown.

For me it was a big advantage to be able to change the library file once, then install the same file for four customers - which took about 10 minutes apiece.

 Really don't know, but I would suspect there is some additional overhead in dealing with two VBA projects and invoking the use of references rather than one using one and no references. 

 On the flip side though, you'd have one bigger VBA project rather than two smaller ones. Internally, that might make some difference.

Jim- any impact to performance?  If the VBA in db2 (db referencing db1’s
vbproject) were to run its own code instead, which would likely finish faster?

I guess I could do an experiment with some loops and UDFs but figured this might be something you know OTOH.
