This is why I continue to use Windows 98 on some systems and Exit to DOS, where I can control all of these functions. However, it is getting more and more difficult to maintain those machines. What modern OS would you recommend?

Your 2003 sln file should still be in your directory. I think all you need to do is load that instead of the converted 2005 sln file (and delete it altogether if you don't want to eventually upgrade) and you should be go to go.

Thanks for your response. I'm trying to get all events in the program to be accurate down to the one millisecond scale.

I'm trying to write a very time sensitive program so I need to make sure that the entire application receives the highest of priorities and that no background tasks are running. I tried using 'SetThreadPriority(hWnd,31);', but other tasks, processes, applications, etc still seem to run and interfere with the timing of my program. Is it possible to make my program such that it is the only task that is running on the computer? Thanks in advance for any help.

I'm trying to access a variable (this->number) from a separate function in a different file. Is there an easy way to do this, like using a global variable or passing the value between functions as one would in C? When I try to access the variable with namespace::functionname::variable, I get the following error message: error C2597: illegal reference to non-static member 'namespace::functionname::variable'. Any help would be greatly appreciated!
