While looking through ri File, I found Windows::Security, and in there  
is a  
method named LookupAccountName. I searched through the mailing list  
archives and google, and didn’t see anything in there about it. The  
problem  
is that I may not understand what’s going on when I’m trying to do a  
search  
in ri. I got as specific as I could and ri says it can’t find anything,  
or  
that I need to be more specific…

C:\ruby\programs\>ri LookupAccountName  
Nothing known about LookupAccountName

C:\ruby\programs\>ri Windows::Security#LookupAccountName  
More than one method matched your request. You can refine  
your search by asking for information on one of:

```
 Windows::Security#LookupAccountName,
 Windows::Security#LookupAccountName

```

Anyway, what I was wondering was what this returned as I’m looking to  
create  
a script using it to search a user’s my document’s folder (for example).  
“c:\documents and settings#{username}” based on who is logged in.  
Alternately, you could let me know if there’s a better alternative, let  
me  
know.

Do you have two copies of the gem installed? ri doesn’t handle that  
at all ☹

Eric,

```
     This is because there are two versions of gems' windows-pr docs

```

in your system. The ri displays information from those docs. So pls hide  
(say, delete/move to aother place ) the doc of one version  
(e.g.windows-pr-0.5.3) and use the other one (e.g.  
windows-pr-0.5.1-mswin32). And you can get correct info from the command  
“ri --gems Windows::Security#LookupAccountName”. Generally the docs  
mentioned above are in “C:\Ruby1.8.5(ruby\_home)\lib\ruby\gems\1.8\doc”.  
Pls reply if still issues.
