Hi, Can anyone please enlighten me how on to load ALL the contents from a (file)stream object directly to a string object. I tried all sorts of way and the only one I found is the stream.read function but it outputs to an array rather than a string object (which defeats the purpose that I''m trying to avoid char arrays) Thanks.. 
    

istream if;
string  str;
char buf[128];
//..


if.get(buf, sizeof(buf));    // want to place the contents straight to str

If your file is a text file, you could try this:
    
ifstream file;
// ...

stringstream stream;
stream << file.rdbuf();
string str = stream.str();

However, if your file is a binary file, this won''t work. The only way (afaik) to get the contents of a binary file into a string is to use a char buffer, and convert that to a string.
