Well it turns out that visual studio 2003 doesn't work on Vista, and is not going to be supported. It just wouldn't work and in the end I had to uninstall it, you forget how many hours it took to install.
Obviously I scanned have used a 2008 after all, is searching on the Web founder couple ways that might get it to work. Next stage was that she trying to use visual studio which is slightly less than intuitive. OK I could write a "Hello World" program, though in the existing projects turned out to be problematic. But after few days everything was hunky-dory.
For one thing when opening the project from an earlier version, don't try opening visual studio first, and then browsing to the project files from within the program it won't open them. On the other hand, opening of projects files from the Windows directory causes visual studio to convert it to the current version.
Another problem I had was something that was a registered bug in visual studio 2008, after spending the day trying to find a solution to that,, I went looking for another solution. I eventually found the Visual Studio 2005 Express Version download page hidden away on Microsoft's Web site.
Using 2005 learned more lot more about conversion programmes from other versions of Visual Studio, and about the aria operating system in particular. It looked like I'd found the solution.
The next step was to convert the neat program to visual studio 2005. Once again ran into problems, NEAT had numerous compilation errors in 2005, and not just undeclared variables. I converted the NEAT code to Visual Studio 2008, and I was able to compile at once I'd fixed at the undeclared variables. I returned to trying to convert the Aria code to 2008 and eventually had success.
Having eventually compile the code the next step was to get it to run on robots. After a number of attempts, we found a utility that allows 2008 code to run on the robots. In fact we were able to run both the 2005 and the 2008 code.
Success at last!
Next, actually writing my own code, the body of my project.
