hello every body
i m a new participent in this forum .
i m working in a very difficult projet for my company
i have to creat a dircetshow filter (in c++) that can send video over network
from a pda with windows mobile (5 or 6) to a pc
so i have written a custom render filter
this is the code any comment?

tell me what are yours opinions
and how can i creat my interface IDSNetSender
((i m using vs 2005))
i m a new participent in this forum .
