Windows Mobile Wifi Networking After Wake Up From Sleep

Question

I am developing a windows mobile application in c# that makes calls to a web service on a separate thread to the UI. This thread runs every few minutes triggered by a timer.

My problem is that if the hand held device goes to sleep, when it wakes up the OS seems to unload the networking and then restart the networking a second or so later.

The result of this more often than not is my application crashes.

Has anyone experienced a similar scenario?

Has anybody had to code around this problem?

Any help or comments would be gratefully received.

Thanks

It sounds like you should add some exception handling on your thread.

Surround your networking code with a try catch block and retry the operation later:

try {
    // your code 
}
catch (Exception ex)
{
    // add some logging
}
