Visual C++ 6.0 is not working??

I have been messing about with some C++ for my mod, basic stuff, like the tutorial on the Valve SDK documentation where you change the speed of the rocket launcher.

Anyway, i am using Visual C++ version 6.0, but it doesnt seem to recognise Solution files, anyone know why. Apparently i need version 7.1, but i dont want to pay 100 quid for something that i feel should be updated rather than re-released.

Version 6.0 wont compile the DLL's and seems to think that the individual .cpp files are programs themselves rather than part of a larger file.

Does anyone know how i can solve this problem? or if any updates are available to make 6.0 compatable with Solution files?

Thanks

As I understand it (I've not tried any of this myself, yet), there's a
program which can convert the solution files into project files that
version 6 can understand. See the SDK programming faq at VERC for more
info.

You can also compile the sources using Visual Studio 2005 Express, which can be downloaded for free from MS.

Ok, ill have a look around, thanks.
