Visual Studio 2010, C++ question.

When building my program, the build takes time to do this

Could that be because the project I'm working on is kinda big (~170 code files excluding externals), or is there something I can do to improve that because my group mate, who has the same laptpo and everything doesn't seem to have this "problem" (It builds perfectly, it is just that it takes time to build it)

I need to be able to pull the state value into the URL with out using GET. Any clue on what syntax I should be using? - _ -; Been stuck on this for a while, right now it's giving me only the first array as AL=Alabama. I need it to be just the value (AL)... Reason I can't use method="get" is because of how the system we post into is set to HTTP POST and I can't change it.

Most computer engineering and computer science majors in big name universities teach a lot of unnecessary courses. You don't need to build an operating system or compiler or build gates or use gaussian distributions or draw circuit diagrams etc...

That's a scary and very incorrect proposition that most of the core classes of a computer science degree are unnecessary.

Again, a computer science major is not just about programming, but preparing you to apply computational skills to solve problems. To do this effectively, you need to understand not only how to program, but what affordances your underlying technology offers you as well as mathematical and computational techniques to tackle the domain-specific problems that you will encounter in your day-to-day job.

To add more:
It's also kinda scary how many students think its a waste of time to take classes that are educational on the hardware topics. Many don't realize the limitations of a software and its processing power requirement. If the computer lacks the computing power then all of a sudden that code you wrote is useless.

It's quite funny though to see pre-med students complaining about taking calculus. The math isn't important to them but utilizing the logistics and critical thinking component of the brain is important in solving medical problems (identifying health problems, performing the minimal amount of tests to effectively diagnose the patient etc...)

It's also interesting at how sadistic pointer typecasting in C is. Nobody should even learn OOP by implementing it in C.

In a C# .asmx web service I am calling an unmanaged c++ .dll. If two people call this web service simultaneously it will crash; it only works if one person is calling it at a time. So am I right to think that both calls to the .dll are running in the same thread and interfering with each other by trying to simultaneously access global variables. If I make all the variables just local variables in the function that is exposed in the dll should this remedy the problem?
