Where is the DOcs on how to find system varibles For User, Custom Property Tab

Hello All, I writing a Macro in VB within the Solidworks2013 Macro Editor, and have it sucessfully connecting to my database in MySQL.

I nned to find the references for the user in Solidworks PDM works 2013 and also where to get the varibles for the CUstm Properties tab interface

that I have for Part, assemblies and Drawings.

We use PDM works to login to Solidworks so I figure i should be able to get my user ID and drop it into my form. So any good reference doc show these varibles

would be handy. Thanks.
