Re: Steganography MFC program problem...
Thanks for the reply.
That is fixed and working now. I have another final problem ...
Well i can compile the program but when i press my Hide button on
UI ...it gives me error saying "encrypted_message.steg NOT FOUND."...
well what could be the problem in this case...the code snippet is same
which i posted in my last post ..and ya ill also copy my OnHide button
code and commenting exactly where i am getting error...
Also if you ll see right at the bottom of my last code snippet there
are 2 while loops (i.e. while(message_encrypt_file)) well cursor is
jumping out from this loop. It is not getting this file....
i am bit lost here now....well exactly what m trying to do here
is ...i am trying to hide message within text file using password.
First i encrypt the message and then i place it in a text file to hide
it...
could you pls let me knw if you think of any problem here.
Thanks a lot
