Transparent connection

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hello,

I have an application for mobile that needs periodical connection to the
central office.
I like to build a class that handles this connection using this sequence :
- if there is network, do nothing
- else if wifi is available, connect to wifi
- else if UMTS is available connect with UMTS
- else if GPRS is available connect with GPRS
- else if GSM is available connect with GSM
- else ..... any network type, this will be extensible

I wonder how to
- enumerate connections
- control connection/disconnection
- check status of one connection

Is there any guidelines to help me ?

Thanks,
Steve B.
