AddressCollection

[Curt_C]

HI,

I want to use the FindListeners function to get a list of the devices that are attached to the gpib.

How do I use the AddressCollection object and an addresslist to find the primary and secondarry addresses of all the devices on the bus. 

Here's what I have so far.

public bool FindListeners()
        {

            try
            {

                m_board = new Board(m_boardnum);
                m_addresslist = new AddressCollection(); 
                
                m_addresslist = m_board.FindListeners();

                Trace.WriteLine("Number of Device found " + m_addresslist.Count);
                Trace.WriteLine("Devices " + m_addresslist.ToString());
                 
 
   
                return true;
            }
            catch (Exception ex)
            {
                Trace.WriteLine(ex.Message);
                return false;
            }

        }

How do I read the primary and secondary address values?

Thanks

Curt

Hi ,

I figured this one out myself.

if anyone is interested, here's how you do it.

Copy the contents of the AddressCollection to an Address array.

        public bool FindListeners()
        {

            try
            {

                m_board = new Board(m_boardnum);
                m_addresslist = new AddressCollection(); 
                
                m_addresslist = m_board.FindListeners();

                Address[] m_address = new Address[m_addresslist.Count ];
                
                Trace.WriteLine("Number of Device found " + m_addresslist.Count);
                Trace.WriteLine("Devices " + m_addresslist.ToString());

                 
                for (int i = 0; i < m_addresslist.Count; i++)
                {
                    m_addresslist.CopyTo(m_address, i);
                    Trace.WriteLine(i + m_address[i].PrimaryAddress.ToString());
                    Trace.WriteLine(i + m_address[i].SecondaryAddress.ToString());    
                }
   
                return true;
            }
            catch (Exception ex)
            {
                Trace.WriteLine(ex.Message);
                return false;
            }

        }
