    debugger crashes and just points to Application.Run(new Form1()); where is my error

    Hello when i run the program it crashes at Application.Run(new Form1()); with this error

    System.ArgumentOutOfRangeException was unhandled

    how can i know where my error is... it looks like a string error but which one ?

    oh nevermind it says it "\comm.cs:line 132"

    ... always when i ask the question just by writing it up I find the answer ...

    oh well i asked the question midas well do something in it ... this is the function at error

            public string loadNextRXPacket()
                // get index of next '11' 
                int i = -1;// rxBuffer.IndexOf(Dw.RXHeader);
                // if we found the packet and the buffer contains a whole packet
                if (i != -1)// && rxBuffer.Length >= (i+Dw.RX_PacketSZ))
                {            // stuff from that index till rxPacketSZ into current packet
                    currentRXPacket = rxBuffer.Substring(i, Dw.RX_PacketSZ);
                    rxBuffer = rxBuffer.Remove(i, Dw.RX_PacketSZ); // erase packet from buffer
                }else { return null; }
                return currentRXPacket;
                //return null;

    edit :::
    well i found that a lot of my problems were coming from the code not being rebuilt correctly. I was clicking the play button thinking the code was being rebuilt and it was not. When I clicked build->rebuild my changes took effect. I was really confused because the function that was causing the error was not even being called anywhere.
