Create a .bat with acad.exe, a PostGIS connection and load 3 tables

Hi,

First of all i am quite newbie in AutoCAD.

I want to create a .bat file or any executable file which runs "acad.exe", adds a PostGIS Connection, and loads 3 specific tables of the public schema in the postgis database.

I need this because i dont want the person that will be executing the file daily, be able to stablish the connection (he doesn't have to know the password for the connection to postgis) and doesn't have to be able to add any other table to the workspace apart from these 3 tables.

Regards,

Aitor
