C++ Problem, Finally!!
The <iostream.h> header, along with lots of other headers ending in .h have been deprecated. You should be including the header files that do not have a .h at the end of them when possible. The exception to this is OS-specific header files such as <windows.h>

Ok this must be wrong. Even when I just include iostream in the header file with no other code in the whole project I still get all the errors.
Does this mean that my iostream file is broken? I can't believe that it is so difficult to get a standard library to work!! Surely I can't have an error in my iostream? I doubt that I would have opened it up and changed anything...
Could somebody send me a 'working' version on iostream.h so that I can rule out this possibility.
Thanks in advance.

Does look like your include files are borked.
Taking a look at XIOSBASE on line 106, it doesn't seem to recognise "streamsize" as a typedef. "streamsize" is typedeffed "int" in IOSFWD. Try copying that file from your MSVC CD to the appropriate include directory. For that matter, try simply reinstalling MSVC.

Actually they can't be deprecated because they were never standard in the first place.

It's not an exception. Whatever the people supplying headers choose to use as an extension, you have to use. So some libraries will have .h, others .hpp, others .hxx, etc.
The C++ standard headers don't have an extension. They acknowledge the possibility that the header doesn't necessarily exist in a file.
make a small example program
#include <iostream>int main() { std::cout << "Hello, World!" << std::endl; return 0;}
For anyone unsure about how to use namespaces, have a read of Migrating to Namespaces. With the original article that it is based upon written in 1999, we should all have migrated by now. Right?
Great articles Pete, in those 9 years or so of C/C++, I've never worked with namespaces worrying about platform compliances, not before learning it is a compliance itself. Living and learning always...
