unable to retrieve lat/long?

[homer09001]

i copied the code form the example in the SDK for C# but im getting a value of 0 when pulling the longitude from FS?

the code:

double longHi = 0;
            double longLo = 0;
            double longitude = 0;
            // Get longitude
            result = fsuipc.FSUIPC_Read(0x056C, 4, ref token, ref dwResult);
            result = fsuipc.FSUIPC_Process(ref dwResult);
            result = fsuipc.FSUIPC_Get(ref token, ref dwResult);
            longHi = dwResult;

            result = fsuipc.FSUIPC_Read(0x0568, 4, ref token, ref dwResult);
            result = fsuipc.FSUIPC_Process(ref dwResult);
            result = fsuipc.FSUIPC_Get(ref token, ref dwResult);
            longLo = dwResult;

            if (longLo != 0)
            {
                longLo = longLo / (65536.0 * 65536.0);
            }
            if (longHi > 0)
            {
                longitude = longHi + longLo;
                input3.Text = Convert.ToString(Convert.ToInt32(longitude));
            }
            else
            {
                longitude = longHi - longLo;
                input3.Text = Convert.ToString(Convert.ToInt32(longitude));
            }
