Setting Nav Freqeuncies

[mpetey3]

I am using the TransmitClientEvent and the NAV1_STBY_SET Event_ID. I am not getting an error when I make the function call but the radio frequencies do not change. I am guessing I am not doing a correct conversion to BCD Hz. What is the easiest way to do this in a .NET language.

Thanks

Just think of BCD as hex data, this way a frequency of 111.20 would be 0x11120.

The TransmitClientEvent line of code for this is:

simconnect.TransmitClientEvent(SimConnect.SIMCONNECT_OBJECT_ID_USER, EVENTS.KEY_NAV1_STBY_SET, 0x11120 , GROUP.ID_PRIORITY_STANDARD, SIMCONNECT_EVENT_FLAG.GROUPID_IS_PRIORITY);

To put this in context, below is the entire program I used to test this:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.FlightSimulator.SimConnect;
using System.Runtime.InteropServices;

namespace SetEvent
{
    public partial class Form1 : Form
    {
        const int WM_USER_SIMCONNECT = 0x0402;

        SimConnect simconnect = null;

        enum EVENTS
        {
            KEY_NAV1_STBY_SET,
        };

        enum GROUP
        {
            ID_PRIORITY_STANDARD = 1900000000,
        };

        public Form1()
        {
            InitializeComponent();
        }

        protected override void DefWndProc(ref Message m)
        {
            if (m.Msg == WM_USER_SIMCONNECT)
            {
                if (simconnect != null)
                {
                    simconnect.ReceiveMessage();
                }
            }
            else
            {
                base.DefWndProc(ref m);
            }
        }

        private void btnConnect_Click(object sender, EventArgs e)
        {
            simconnect = new SimConnect("SetEvent", this.Handle, WM_USER_SIMCONNECT, null, 0);
        }

        private void btnSetEvent_Click(object sender, EventArgs e)
        {

            simconnect.MapClientEventToSimEvent(EVENTS.KEY_NAV1_STBY_SET, "NAV1_STBY_SET");
            simconnect.TransmitClientEvent(SimConnect.SIMCONNECT_OBJECT_ID_USER, EVENTS.KEY_NAV1_STBY_SET, 0x11120 , GROUP.ID_PRIORITY_STANDARD, SIMCONNECT_EVENT_FLAG.GROUPID_IS_PRIORITY);
        }
    }
}
