Cetin,
Thanks for your reply and code examples. What really helped and solved my problem was the fact that the FileStream object has Length and Position properties that I can use.

Thank you for your help

Sincerely,
Einar

>Say you set buffer length as 1192 and actual data is 1193 bytes. It'd read the first 1192 bytes into buffer array. Then on next 'line' it'd only read 1 byte and rest of the buffer array elements would be the values left over previous read. Since using the return value intBytesRead you know how many array elements to check as part of actual data.
