Bluetooth adapter not found scenario

(1/2) > >>

TheodorosGR:
I have the following scenario on my application.
Application is starting.The bluetooth adapter is not pluged(i think this is common from a lot users).Show an exception from Enum_Radios() (wcl demo).The exception says what to do(check your adapter....etc).Then if the user plugs the adaptor he will probably hit the refresh button (GetSelectedRadio()).But there i am getting an exception which i cant handle.
My question is if there is any way after the user plugs the adapter and calling GetSelectedRadio() to display the BT adapter without requiring restarting the application.
A little bit confusing question but i think you got the point.
Regards
Thiodor

Good day!

WCL Has no GetSelectedRadio function. What does that function do?

Of course, WCL can detect changes in hardware without restarting application.

TheodorosGR:
Here is the code.

--- Code: --- private wclBluetoothRadio GetSelectedRadio()
        {
            wclBluetoothRadio Result = null;

            if (lvRadios.SelectedItems.Count == 0)
            {
                Result = new wclBluetoothRadio();

                try
                {
                    Result.API = wclBluetoothDiscovery.StringToBluetoothAPI(lvRadios.Items[0].SubItems[1].Text);
                }
                catch (Exception )
                {
                    MessageBoxEx.Show(Resources.PlugAdaptorGR + ".Error code:201", headerMSG);

                }
             

                //MessageBox.Show("Select radio", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            }
            else
            {
                Result = new wclBluetoothRadio();

                try
                {
                    Result.API = wclBluetoothDiscovery.StringToBluetoothAPI(lvRadios.SelectedItems[0].SubItems[1].Text);
                }
                catch
                {
                    Result = null;
                    throw;
                }
            }

            return Result;
        }

When and how lvRadios items created and inserted in the liist view

TheodorosGR:
I think you need this:

--- Code: --- private void ShowRadio(wclBluetoothRadio Radio)
        {
           
            String Address = "";

            try
            {
                Address = Radio.Address;
            }
            catch (Exception e)
            {
                Address = e.Message;
            }

            ListViewItem Item = lvRadios.Items.Add(Address);
            Item.SubItems.Add(wclBluetoothDiscovery.BluetoothAPIToString(Radio.API));

            try
            {
               
                Item.SubItems.Add(Radio.Connectable.ToString());
            }
            catch (Exception e)
            {
                Item.SubItems.Add(e.Message);
            }

            try
            {
                Item.SubItems.Add(Radio.Discoverable.ToString());
            }
            catch (Exception e)
            {
                Item.SubItems.Add(e.Message);
            }

            try
            {
                Item.SubItems.Add(Radio.Name);
            }
            catch (Exception e)
            {
                Item.SubItems.Add(e.Message);
            }
        }

--- End code ---
