I'm trying to bind a oracle stored procedure to a listbox using .net c# winform. Can someone tell me what I'm doing wrong?

My oracle SP is defined as:
    PROCEDURE client_find
            ( p_client_name IN client.name%TYPE
            , p_last_trade_date IN client.last_trade_date%TYPE
            , p_is_active IN client.is_active%TYPE
            , io_cursor IN OUT t_cursor)

OracleConnection Oraclecon = new OracleConnection("Password=;" + "User ID=;Data Source=;");
            Oraclecon.Open();
 
            OracleCommand myCMD = new OracleCommand();
            myCMD.Connection = Oraclecon;
            myCMD.CommandText = "client_select.client_find";
            myCMD.CommandType = CommandType.StoredProcedure;
            myCMD.Parameters.Add("p_client_name", OracleType.NVarChar).Value = null;
            myCMD.Parameters.Add("p_last_trade_date", OracleType.DateTime).Value = DateTime.Now.ToString("dd/MM/yyyy");
            myCMD.Parameters.Add("p_is_active", OracleType.Int16).Value = -1;
            myCMD.Parameters.Add(new OracleParameter("io_cursor", OracleType.Cursor)).Direction = ParameterDirection.Output;
        
            DataSet ds = new DataSet();
            OracleDataAdapter adapter = new OracleDataAdapter(myCMD);
            adapter.Fill(ds);
            
            this.lstActiveClients.DataSource = ds;
            this.lstActiveClients.DisplayMember = "name";
            this.lstActiveClients.ValueMember = "client_key";

I'm getting a wrong number or types of arguments to client_find when it executes the adapter.Fill(ds);

Ok, i had the name set to null... i fixed that, but now my listbox doesn't show any data from the SP.  It just shows one line that says System.Data.DataViewManagerListItemTypeDescriptor

You need to assign the datasource a datatable or object collection.
this.lstActiveClients.DataSource = ds.Table[0];
