Hi,
I'm creating an application for the Windows Mobile platform,
using .NET CF 2.0. This application uses UDP packets (they want it
this way) and if I use it with the device wireless network, it works
flawlessly. Now if I try using it with the GPRS connection (of course
I first disable the active WIFI connections) it simply doesn't work.
The only way I can get it working is by starting Internet Explorer so
that it triggers the GPRS connection. Every application can trigger it
but mine. I also tried to put a simple TCP connection to a host (Just
in case it's shy with UDP packs..) but doesn't work either... so I
really can't figure out what may be missing. Everything works just
fine if I start the GPRS connection with another application. But I
can't find the classes to do this is C#. Do you have any hints???

You have to contact the Connection Manager and ask it to make a connection, 
if there's no other connection you want to use.  I'm sure that, if you 
search the archives of this group,

OpenNETCF Smart Device Framework wraps the APIs that you need to call.
