User Name via 1. API, 2. Enviornment, 3. WScript.Network
 

All,

I have reviewed the several ways of retrieving a User Name from various
postings here. I have listed 3 below. Are the results of each is coming
from different places? Can someone tell me from where each is pulling the
UserName info?

I am currently assuming that the API & WScript are coming from the same
place since I rec'd the same answer (until someone tells me otherwise). Are
there pros/cons of using the WScript vs. API function?

Thank your for any assistance.

I would assume that they all get the answer from the same place, just use
different (more accessible) methods of extracting it. They should all return
the same value, they do on my box(es).

Bob - thanks for responding.

On my system, the API & WScript return the same answer.
The Environ returns nothing.
I checked "Set" in Dos and sure enough, there is not a UserName variable.

Thx

I have heard a couple of different ideas on environ vs API. One is that
Environ was not uspported by Windows 98 / ME. The other is that the API
returns the network login, while environ returns the windows login (which
although not normally differnent can be). I am not too sure if or what is
true. I always just use environ.
