Hi im reading a file and im using the read function from the 'ifstream' class has been depreciated, so I was wondering what I should be using instead? eg ifstream file("data.txt"); file.read(fileBuffer, fileLength);

file >> fileBuffer

or

FILE* fp;
fopen("myfile.txt", "rb");
fread(buffer, size, 1, fp);

ifstream::read hasn't been deprecated; that was a mistake on Microsoft's part - they were a bit overzealous in marking functions as "deprecated". It certainly won't be in the final version of VS 2005 (which is still in beta, remember, so there are bugs).

file >> fileBuffer

Just a pointer (no pun intended[wink]), but on its own, this is just a bit unsafe. If you use this you'll want to call ios_base::width before you do this, in order to avoid buffer overflow exploits.
