I just tried #include <fstream>
Im using MFC too so it is one of my older projects when I didnt use pure Win32.
It still has errors with my ifstream and ofstream data types..
I have a few other errors with my project as well i havent metioned.. such as
WriteHuge for CFile is not a member?
This is giving me problems at:
and
at:
however the majority of the problems subside in the ofstream and ifstream routines?
coder requires 0xf00d before continue().

could someone show an example of using ifstream and ofstream in vc++ 7 just somthing small? I tried typing in using namespace std; in the header no luck?
ok after putting the using namespace std;
in the stdafx header.. it kinda works but now it says using
ifstream in;
in.get(ch) no work?
nor does
filebuf::sh_read
and
ios::nocreate

well for some code here... sorry if its not my best work .. its rather old but I wanted to convert it to work with VC++ 7 so
errors in ifstream with get i have this:
errors in ifstream with get i have this:
