Checking for internet connectivity

[TWELVE]

Hello Fellows,

how can i check that an internet connection is present - primarily on the device - passively, beside any active approach that tests the connection by ping or udp/tcp connect...?

Depending on the settings, testing the connection may initiate to open a connection ( i.e. dial up), which i want to avoid especially on the device due to certain concerns like costs etc. ( the connection testing will consume some traffic over time = costs).

I'm sorry if that question has already been answered, my search was not successful.

regards,

TWELVE

Did you try agraham's SystemState library: http://www.b4x.com/forum/additional-libraries/3346-systemstate-library-wm-5-0-later.html

There are several relevant properties which may work (like ConnectionsNetworkAdapters).
This is the list of all properties: SystemState Properties (Microsoft.WindowsMobile.Status)

Hi Erel,

thanks for the hint, however i wanted to keep my programme compatible with WM2003 as long as possible...

Due to your efforts for the Android stuff i am wondering if you continue B4P...? A function in B4P that can detect the network connection state would be nice...

regards,

The SystemState API's are the way to do it. Unfortunately it is only supported by WM5 and above.
