Hi Tim,
I am getting the error, even when my file is just 65 bytes. Its also evident
from the output (where I am capturing number of byte recieved). I have
posted my output in the previous posts.
Also, if I want to transfer large files (image files of size 100K or more),
than what should be the best approach. It will be very nice if you could
share some code snippet, explaining this.
Thanks,
Manu
