Connection Manager and Network Timeouts

Hello there,

I'm trying to create a persistent connection application on Windows Mobile
6. I intend for this application to use mobile radios (GPRS) to communicate
with remote servers using Connection Manager for long periods of time (days).
However, there appears to be a problem with my connection manager code.

It appears to me that we are either getting killed by the network, or the
device is timing out the session. I can't figure out which.

Is there a particular set of calls to Connection Manager that need to be
made to
a) make a persistent connection that last days? (should I use always_on?)
b) register to be notified if a connection is terminated either by Windows
Mobile or the network?
c) What is the event that I should be capturing to re-establish a killed
connection manager handle?

Right now we are attempting "Get Connection Status" before making network
calls, but it doesn't seem to be working quite right.

Any help appreciated!

Connection Manager gives you the ability to pass a window handle (see the
MSDN documentation) so it will inform your window when the connection status
changes. Depending on what the status is you can then request a reconnection
or "work offline" if a connection is not possible.
