The forum will experience an outage sometime between February 10 at 7:00pm EST and February 12 at 11:59 EST for installation of security updates. The actual time and duration of the outage are unknown but attempts will be made to minimize the downtime. We apologize for any inconvenience.

It's being thrown as an exception by ULConnection.Synchronize() in a C# SQL Anywhere 12 UltraLite.Net Windows Mobile application.

Does it mean that the MobiLink client can't find the MobiLink server? Nothing is showing up in the MobiLink server -ot file.

Is there any way to get more diagnostic information about this exception?

If you are getting the error SQLE_MOBILINK_COMMUNICATIONS_ERROR code, a good step to start diagnosis would be to check the system specific error code, which should be returned with the exception.

@Tyson: OK, but how? Here on SQLA we REALLY LIKE actual code examples. BTW SQLE_MOBILINK_COMMUNICATIONS_ERROR does not appear anywhere in the Help, nor in a Google Search.

Based on an example from our documentation:


public void Sync()
  {
         try
         {
            _conn.Synchronize( this );
            _inSync = false;
         } 
         catch( ULException uEx ){
            if( uEx.NativeError == ULSQLCode.SQLE_MOBILINK_COMMUNICATIONS_ERROR )
            {
               MessageBox.Show(
                    "StreamErrorCode = " + 
                     _conn.SyncResult.StreamErrorCode.ToString() + 
                     "\r\n"
                  + "StreamErrorContext = " + 
                    _conn.SyncResult.StreamErrorContext + "\r\n"
                  + "StreamErrorID = " + 
                    _conn.SyncResult.StreamErrorID + "\r\n"
                  + "StreamErrorSystem = " + 
                    _conn.SyncResult.StreamErrorSystem + "\r\n"
                  );
            }
            else
            {
               MessageBox.Show(uEx.Message);
            }
         }
         catch(System.Exception ex )
         {
            MessageBox.Show(ex.Message);
         }
  }
