GMobileSync

A few people have mentioned to me that it's hard to tell if their credentials are wrong or if a network connection is not present when using GMobileSync. Version 1.1 does not check for network connectivity before trying to connect to Google Calendar. Version 1.2 does a quick check to make sure the device has a valid network connection before trying to synchronize. I found a reference showing how to do this in VB.NET on MSDN for Windows Mobile 2003. Since I'm targeting Mobile 5.0 users and using C#, I had to modify the code slightly.

using System; using System.Net; public static bool IsConnected { get { bool connected = false; try { IPHostEntry thisHost = Dns.GetHostEntry(Dns.GetHostName()); string localIpAddress = thisHost.AddressList[0].ToString(); connected = localIpAddress != System.Net.IPAddress.Parse("127.0.0.1").ToString(); } catch (Exception) { connected = false; } return connected; } }

Now, before any network activity, I check the IsConnected property. This will help with identifying error messages properly in GMobileSync.
