Greetings all,

First post here, please be gentle :)

I have searched around for an answer without success so I thought I
would post here to see if anyone may be able to point me in the right
direction.

I have a need to develop an app for my research project, that has the
ability to inspect and display the headder information from an IP
packet, recieved through the 802.11 wireless interface of a PDA device.

I have searched for managed code examples on how to obtain packets from
an Windows Mobile inbuilt library's but have not found anything...

I am also looking at the OpenNETCF.org framework for any leads on how
to achieve this..( & without sucess as well at present...)

If anyone has been down this path or has any advice I would appreaciate
it.

Still not clear. Where is this packet directed? To a socket on the device?
Why shouldn't the program that's receiving the data just do the right thing?

You may be able to achieve what you're trying to do with a layered service
provider, but you can't do that from managed code. I'm reluctant to go in
detail about this or any of the other possibilities until we understand what
the heck you are actually trying to do.

Hi Paul,

Many thanks for your reply.. The application can be thought of as a
modified wireless sniffer similar to netstumbler and many others.. and
in this case I need to capture a packet which is not necessarily
directed to my device. Bascially, I want to examine any packet 'sensed'
(for the lack of a better word) by the RF interface and view the header
info.

Your suggestion for a Layered Service Provider has given me some good
leads to follow up with, many thanks.. I found this article which looks
interesting..

I can see this is really the realm of many spyware apps, that capture
packets and divert them to alternative destinations. However, an
ability to capture a packet, embed information into a header and then
retransmit the packet to the original destination would also very
useful to my research topic.

Many thanks
