If I understand you question correctly, you want to express Oracle user defined types in WCF services? This will really depend on the protocol to be used.

const correctness is still const correctness regardless of whether you use the STL or not. I believe what you are looking for is to make registeredNames a "const char **" so that the assignment to registeredNames[i] (which is a const char *) works.

Depends on the compiler, but with gcc (for example, since that's the one you referred to), some of the standard (both C and POSIX) functions have builtin "compiler intrinsics".

A general way to find out the answer to this question is to load the page you want to delegate to (http://technorati.com/people/technorati/USERNAME in this case), look at the source, and find the server tag used there.
If there are openid2 tags, you should copy those as well.

If you are not expecting that input, reject it.
You should always validate your inputs, and certainly discard anything outside of the expected range. If you already know that your URL's honestly won't be beyond a certain length then rejecting it before it gets to the application seems wise. |
Cliff Click has dome some major research on lock free data structures by utilizing finite state machines and also posted a lot of implementations for Java. You can find his papers, slides and implementations at his blog: http://blogs.azulsystems.com/cliff/ |
I'd say no. It's just false security. Just program well and check your requests for bad stuff. It should be enough.
Also, it's not future proof. |
Yes. If it's too long and you're sure then reject it as soon as possible. If you can, reject it before it reaches your application (for example IISLockdown will do this).
Remember to account for character encoding though. |
Better than checking length, I think you should check content. You never know how you're going to use your URL schema in the future, but you can always sanitize your inputs. To put a very complex thing very simply: Don't trust user-supplied data. Don't put it directly into DB queries, don't eval() it, don't take anythi... |

I really would choose C# instead of C++. For Windows client apps, it can't be beat. For C/C++ dude like you, the syntax learning curve will be short. The difficulty will be learning the .NET framework, but that's the cost you'll have to incur one way or the other.

It should be just fine. It supports C# 3.0 now. I usually try to stick with targeting 2.0 though and it is very stable.
