Simple API Program

I managed to get it working!

(Sort of...)

What I haven't figured out is how to subscribe to Slice, Panadapter, etc etc. In the following code snippet, I can see how to get radio and therefore _thisRadio. I don't know what to do to get slice (I didn't see anything like API.RadioAdded, except for slice info). The commented lines at the bottom are some of the things that I have tried based on a post from Eric. Anyone able to help? I included the source at the bottom of this post so that you can see the whole thing.

  public partial class frmMain : Form

  {

    private Radio _thisRadio;

    private Slice _thisSlice;

    public string NL = Environment.NewLine;

    public frmMain()

    {

      InitializeComponent();

      API.RadioAdded += API_RadioAdded;

      API.RadioRemoved += API_RadioRemoved;

      //API.ProgramName = "K1PGV's test Program";

      API.ProgramName = "KD0RC test Program";

      API.Init();

    }

    private void frmMain_Load(object sender, EventArgs e)

    {

      CheckForIllegalCrossThreadCalls = false;

    }

    private void API_RadioAdded(Radio radio)

    {

      _thisRadio = radio;

      modelTextBox.Text = radio.Model;

      serialTextBox.Text += radio.Serial.Substring(0, radio.Serial.Length - 4) + "****";

      radioIPAddress.Text += radio.IP;

      // The properties, such as Nickname and Callsign, can't be read

      // successfully until you've received a PropertyChanged event

      // for that property... this is done after connect.

      //

      radio.PropertyChanged += radio_PropertyChanged;

      _thisRadio.Connect();

      //_thisSlice = radio.TransmitSlice;

      //radio.SliceAdded += new Radio.SliceAddedEventHandler(radio_SliceAdded);

      //slice.PropertyChanged += new PropertyChangedEventHandler(slice_PropertyChanged);

    }

Hi Alan, Yep, that is what I did in C++ in my TeensyMaestro, and it works great. In this case, I am trying to use C# with FlexLib and am struggling with understanding both (I grew up on PL/I, Fortran and COBOL, so C constructs don't come easily).

Do you know how I would do the subscriptions in C# using FlexLib?

I think that if I can get the Slice event handler established and working, I will be all set, but maybe there is more to it than that... To that end, I don't understand how to define a slice variable that isn't always null.

OK, I finally got it... I found another GitHub example that I was able to get a (partial) understanding of, so now I can get slice info.

I am at the "get it to work now, understand why later" stage of C# and the FlexLib.

Being used to the API text commands, this is taking some getting used to... In any event, I think I am now able to experiment with what I have working at this point. The large textbox on the right is a debug window to make it easier to see radio data real-time, instead of going to the console window after the fact.

I can only imagine the rookie C# mistakes I am making at this point, but it is fun to see it up and running.

Hi Al, here is a link to the sampler:
