I'm new to IdeaBlade so bare with me if this seems basic. I'm developing an application that I want to provide Offline functionality. I want to be able to detect if the database is available BEFORE showing my login. If it's not available I want to load the offline data, otherwise I want to continue on using the connected database.

Several other options -

  • The .NET class NetworkInterface GetIsNetworkAvailable() method can tell you if any network connection is available.
  • The IdeaBlade.Util.HttpFns.PingServer() method can be used to test if the server is available.  This method has also been tweaked a bit for the 3.5.0 release coming next week to better identify availability conditions.

A Login is required before calling CheckDataSourceKey as a security precaution.  I guess it could be argued either way as to whether this is wise, but that's the way it works now.
