GetEnvironmentVariable('USER');         

that works ,but now my application will run with root priviliage so that function will return "root"  as the user name
is there any way i can list all the computer users "not only the current user" ?

What do you want to achieve?
Sounds like you don't know yourself ;-)

It's easy.

Take a look at the users unit in the users fpc package. It contains everything you need. GetUserList, and GetUserData combined with FpGetuid from baseunix sounds like what you want :)

That's ofcourse a very unix specific unit :)
