thank you Olli , but i have talked with One of the Developper of PANDA
Av , about this , so he replayed me that it can be possible to dump a file then do a search on that saved dumped file with the Function POS .he even sent me an exemple for that and i saw how does it work .
so dumping a File is a solution but not enough especially when dealing with big Files ( tht'a what he advised me ).
when i said There is no such thing as a "hex value". i mean i can convert some Hex into s string then search for this string in the file .
thank you
