Hi

First sorry for my english, i dont learn at all yet

Im using an byte array

byte[] receiveBuffer = new byte[BUFFER_SIZE];

BUFFER_SIZE<-- this is constant
But receiveBuffer is inside of a loop waiting to catch the next information, but if I catch a long quantity of information it is noerase when i catch a minor quantity of it.
So for this is that i must clean the "receiveBuffer " array

I hope that someone help me, i really need this, or if some knows an alternative it will be helpful

Thanks a lot =)
