    Code:
    char Buffer[256];
    ifstream File;
    File.open("MyFile.txt", ios::in);
    
    if(!File.fail())
    {
       while(!File.eof())
       {
          File >> Buffer;
          cout << Buffer << " ";
       }
       File.close();
    }

    Replace File >> Buffer; with
    File.getline(Buffer, 255, EOF);

    getline() reads a line from the file (with a max of 255 chars) of course .

    What you have to be careful about is actually using >> to read/inpout since it reads only to the character return not skipping it while getline() reads the entire line and skips past the character return.

    But that's what it's suppose to do (read the manual pages). I'm just saying the geline function in VC++ 6.0 is not working like descibed in the manual pages because it has a bug!
