I couldn't find any use of the SlidingBuffer since i don't understand what it basically does.

 So if anyone could explain, nor better post a sample application i would be glad. By the way there is absolutely no documentation on it ( check yourself here : http://www.opennetcf.com/library/sdf/html/0a1b6572-6c05-9a6b-47ae-db287fa883d5.htm )

Thanks you for any tips :)

It does exactly what the name suggests: it's an sliding (i.e. unbounded) buffer. You write to the buffer using the Append method and read from it using the Read method. There's nothing more to it.
