Best way to tell if web service is running? 1

[ookete]

Hello,

I am making my very first Pocket PC application (VB.NET), and I am using a web service to write data from the device to a database on the server. There will be times the Pocket PC will be unable to talk to the web service, and in that case I would like to store data locally until the service becomes available again.

What is the best way to check if the service is accessible from the Pocket PC app? I appreciate any advice! Thank you.

i havent done much pocket pc programming, but i do have an idea,

there is a HttpWebRequest class that can be used to access any page on the web (like a crawler).

you could maybe use this and try to contact the asmx file, if the system is able to connect then it will return back a found status or it will return back a 200 status(if i am correct)...

Known is handfull, Unknown is worldfull

Or you could simply ping the server

Have a look at the System.Net and System.Net.Sockets classes

And for the benefit of the poster, here's a MSDN article showing how to do it:
