David,

The If statement is serving two purposes. It is issuing and checking the
call to the API in one statement. If GeteUserName is not successful, it
returns a 0, which will resolve to false in that statement. If it is
successful, it retunes 1, and the following statement strips off the
null
terminator which is a common need when working with APIs.

To get more details about APIs, I suggest checking out www.allapi.net,
and/or getting Dan Appleman's guide to the Win32 API.

Bob,

Cool trick & works great! However, I'm confused as to
what the if statement is doing? When does it do the Left$
and when doesn't it? Is there information about the
various librarys/Controls such as advapi32.dll?

David
