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!

Re: Can Vb.Net do this?

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!

RE: Can Vb.Net do this?

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

Re: Can Vb.Net do this?

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 :)

Re: Can Vb.Net do this?

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?

Re: Can Vb.Net do this?

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.)

Re: Can Vb.Net do this?

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.

Re: Request for help canceled.....

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.

There are 10 kinds of people - Those who understand Binary and those who
don't.

I spoke too soon.

I didn't take into account that the Sprint server requires a login to send
mail and the Bellsouth servers don't. That means that to handle the problem
from an Outlook point of view I would have to muck around with VSTO and
God-only-knows what else.

I have another idea that just might work though. I'll let you know.

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?

Well I don't know how to listen to the (dis)connect events, but you
can check whether the network connection is enabled or disabled by
looking at the verb name for the connection. While the article was
written to enabled/disable the network connection you could modify it
to just return whether the connection is enabled or not:

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 :)

I used a handler for the NetworkChange.N etworkAddressCh anged event, and it
seems to work just fine.

I guess that only works for English versions of Windows. If you want to
use that for a program that's going to be used in other countries just
checking if a certain text appears in the name will fail.

Unfortunately you're correct (it also fails if you rename a
connection) - but I don't know how else you could match a specific
connection.
