https://forums.autodesk.com/t5/autocad-forum/access-2013-dataabase-compatibility/m-p/5620407#M330845 <P>I'd recommend doing managed dotNET using C# or VB over VBA.&nbsp; It gives you access to some highly useful methods to connect to data sources such as a SQL Server database.&nbsp; Note I deliberately say "data source", as the methods used can be easily used to&nbsp;black-box the interface so you can connect to XML, Access, SQL Server, or other data sources without rewriting everything.&nbsp; With minor effort you can also set up LISP functions to call the same procedures (within reason - there are a few limitations inherent to&nbsp;LISP).</P> <P>&nbsp;</P> <P>The documentation doesn't expand a lot on details of building custom connections to databases, since that is handled by the customization method chosen and has little to do with AutoCAD or associated vertical products.&nbsp; For example the System.Data.SQL namespace is under the jurisdiction of Microsoft, and provides dedicated means to work with SQL Server.&nbsp; How you use that will be the same regardless if you are using vanilla AutoCAD, Civil3D, or a stand-alone application.</P> Mon, 04 May 2015 19:47:36 GMT dgorsman 2015-05-04T19:47:36Z
