Display Sharepoint User Name in Textbox

[kelvin2088]

My access tables are stored in sharepoint. (as lists) And currently I'm using desktop version access 2010 as User Interface.

I coded the database the way that everytime user open it, it prompt the user to input sharepoint login and password.

Problem: How could I display logged in sharepoint user name in a text box of navigation page for further use? (such as setting filters and stuff).

Thanks!!!
