Show column user in grid

Hi, I need to show a field called USER in a grid. In that field I need to load the user that creates the register. How can do that using the login username?

Thanks.

Look at the document library application example. It uses the user id of the person saving a document to become the owner of the document
in the form_tb_documents application. There is a global variable [usr_login] that you can use if you implemented the SC security module. [ATTACH=CONFIG]n71343[/ATTACH]
