Hello,

How can I create an application/win-service in .NET that runs in the
background and detects automatically when the computer connects to the
internet?
I want to have a program that runs in the background (as service?) and when
the comuter connects to the internet, it will send the IP automatically to
an e-mail address.
Any idea?

Thanks,
Tom.

What are you, a newbie script kiddie? :)

System.Net.NetworkInformation.NetworkChange class,
NetworkAvailabilityChanged event can monitor this.

System.Net.Mail has classes for sending mail, assuming you've got an
SMTP server you can send it to.

But don't hurt anyone with this information!

It's OK friend, I'm not pretend to be the next internet spoiler... is just
that I suspect that one of my employees deals with business data, and
although I pay my best money to detective agencies, they are all helpless...
I want to prove them that it's much simplier than they think...
But thanks anyway!
;-)
 
Hi Tom,

You might find following KB useful:

#How to determine the connection state of your local system and how to
initiate or end an Internet connection by using Visual Basic .NET or Visual
Basic 2005
http://support.microsoft.com/kb/821770

You can periodically call InternetGetConnectedState() in your program to
determine current status.

For sending email part, you might also find following website useful:

Hope this helps.

So you want to create a backdoor program, imbed it into a picture (see
other thread) and then have that program report itself to an email
address giving you access to that backdoor program. And you expect us to
help you. If it's really one of your employees like you state in one of
the answers, then it should be a breeze to find his IP address on your
local network, just ask the sysop.
 
Hi Tom,
