[Lazarus] Handling Firebird connection

[Richard Mace]

Hi all,

I have the following code that I use to connect to a Firebird database,
which works fine, however, if the Firebird server becomes unavailable,
fIBConnection.Connected always returns true. What's the best way of
checking to make sure that the Firebird server is still available before I
attempt to connect to the database?

Thanks in advance

Richard

  fOnline := True;
  try
    if fIBConnection.Connected then
      Exit;

        with fIBConnection do
          begin
            HostName     := 'hostname';
            DatabaseName := 'location';
            UserName     := 'username';
            Password     := 'password';
          end;
      end;

    fIBConnection.Transaction  := fSQLTransaction;

    with fSQLQuery do
      begin
        DataBase := fIBConnection;
        Transaction := fSQLTransaction;
      end;

    //Finally switch on connection
    fSQLTransaction.DataBase := fIBConnection;
    fIBConnection.Connected := True;
  except
    fOnline := False;
  end;
