Can Vb.Net do this?

[jim]

I have a user that uses a built-in wireless ethernet card to connect to our
wireless router and surf the internet from behind our router and uses a
wireless Sprint card to connect to the internet when not in the office.

I need to be able to detect when he is connected from the office and when he
is connected via the Sprint card.

Monitoring the status of the Local Area Connection may not be the best
solution because he may use it to connect at hotspots outside the office and
I need to know specifically if he is connected at the office (AT&T/Bellsouth
DSL) or to another hotspot on the AT&T/Bellsouth DSL network.

Any ideas? Any sample code?

Thanks!

Yeah...I know.....this is a CSharp group....but I could use your help too.
I can convert the CSharp code ( I think) if you know of any that can help me
do this.

Thanks for you help!

if i understand you correctly ,,

You need to know if a person is connected from your office to the internet
or at another place

this is pretty simple , just check if a known location at your intranet is
availlable
( for instance by pinging )
:-) or am i thinking to simple

that wouldn't tell if you are connected to two different types of
connections... that would just tell you if you had an internet connection or
could reach a server ;) but that could work in this instance for him, never
know.. in our office though we have pinging disabled internally.. and
external pings also.. so in our case ping wouldnt work but this isnt us :)

That's a good idea. But, to keep from constantly pinging for the server, is
there a way to detect the disconnection and connection events of the Local
Area Network card?

I have to ask, who/what needs to know the manner of connection and why?

If the who is the corporate office and the why is to monitor behavior, there
are a number of ways of determining the connection, mostly they are
infrastructure solutions. If your router or switches support logging, you
can read the logs and determine the connection.

If the who is an applicatoin and the why is to alter behavior or options,
then you can enumerate over the installed NIC's and determine if they are
active. You can accomplish this with unmanaged API calls
(planet-source-code.com, mvps.org/vbnet), with
system.net(Netw orkInterface/Adapters), and from managed WMI . You can even
capture events when network configurations change.

Beyond that you can create a mixture of the two solutions. The query
portions (option 2) resides on the client as a service or some such and a
controller will live at the home office (Option 1/alternative - roll your
own monitor service.)

There are 2 users that have 2 profiles in outlook 2003. They need 2 profiles
because the office DSL only allows emails to be sent via Bellsouth mail
servers and when on the road, their Sprint mobile wireless only allows
emails to be sent via Sprint servers. (Both ISPs say that they have these
restrictions to help stem the flow of spam.)

Since you can't have 2 mail server entries in a single profile, you need 2
profiles.

This can be a pain in the arse...as there is no way (that I have found) to
keep the 2 profiles in sync on a single PC. And, the few Outlook PC-to-PC
profile syncing apps that I have found don't sync everything (folders as
well as contacts, messages, etc.).

I found a way to change the outgoing email server automatically, but I have
to reliably detect where they are and make system changes automatically if
they change where they connect to the internet.

If I can detect that the Local Area Network connection has "connected" , I
can then do the simple ping that is suggested here and make changes (or not)
depending on the ping's response. And, if I can detect the "connected"
event, I can avoid constant pinging and reserve system resources. (I just
hate wasting CPU cycles and such...)

If anyone knows of a better solution, I'm all ears.

You seem miffed that it took you as long as 6 hours to find a solution to
your 'problem'.

I recommend that you learn to be patient because you will encounter
'problems' that will take you days if not weeks to fimd a solution for.

Jim, maybe it would be a good idea to let us know what you did to
overcome your problem, afterall, we can all learn from each other and
maybe save someone else spending 6 (or more) hours later!

There's probably lots of ways to overcome your problem, but I for one
would be interested to read, even a brief description, of what you
decided on.
