If it's a programming language you want then I'd say something which is known for string processing power so that would mean perl.
However the task you require can be rather complicated since you need to 'know' the language, so you would require to follow the same steps the compiler does, being lexical and grammatic... |
Start with each include file, and ensure that each include file only includes what is necessary to compile itself. Any include files that are then missing for the C++ files, can be added to the C++ files themselves.

In building a few iterations of CMSs, some of the key things turned out to be:

Are you not using the [XmlSerializer][1]? It's pretty damn good and makes doing things like this real easy (I use it quite a lot!).

Without knowing the exact structure of your tables or what type of database you're using it's hard to answer. However if you're using MS SQL and if you have a true date/time field that has different times that the records were entered on the same date then something like this should work:

You should check out Reflection and the Activator class. They will allow you to create objects from strings. Granted, the object has to be in one of the assemblies that you have access to. |
Here are a couple of factors to consider:

Hibernate does/can use bytecode generation (CGLIB) so that it knows a field is dirty as soon as you call the setter (or even assign to the field afaict).

Since each User-Widget combination is unique, you should represent that in your table by making the combination unique. In other words, go with option 2. Otherwise you may have two entries with the same widget and user IDs but different user-widget IDs. |
You don't have to have a certificate on your server; it's up to the client whether they are willing to talk to an unauthenticated server.

Create work mandates that define the problem that needs solving. Your work is constrained by only needing to implement that which is necessary to solve the problem.

I have used it for convenience for a very small project. It did what I wanted and saved me a couple of days work.

Experience. Learn the patterns and real-world examples of their uses. Every time you have a design decision to make, think if a pattern you know would apply to it. Over time, you get better and you discover new ways to apply the patterns to a wider range of problems. |
Haskell has a relatively recent language-c project <http://www.sivity.net/projects/language.c> which allows the analysis of C code.
If you are familiar with Haskell, then it might be worth a look. Even if you are not, it might be interesting to have a go. |
Another great book I found was:
Refactoring to Patterns
By showing when, where and how you can alter existing code to patterns, it gave me a much better understanding of the concepts, and an ability to identify where they can be used. |

How did you learn when to use an if statement?
I liken it to that because its a larger construct that you need to know the ins and outs of before you can use it effectively. An if statement solves a class of problems needing branching. A bridge pattern solves a class of problems. I really don't view them any diff... |
As far as I can see, it'd only be useful from an organizational standpoint. I can't really conceive of any logical value in doing that. Perhaps someone will have a proper example. |

One reason for doing this is that the variables 'z' and 'zz' would not be available to code below the end of that inner block. When you do this in Java, the JVM pushes a stack frame for the inner code, and those values can live on the stack. When the code exits the block, the stack frame is popped and those values go a... |

For some reason the combination of swfobject.js and script.aculo.us Ajax.Autocompleter on the same page causes the latter to fail. Autocompleter doesn't make its Ajax request. A separate Ajax control on the same page that uses Ajax.Updater doesn't seem to have the same problem.

Exactly one return from any function. That way you can do deallocation there and never miss it.
It's too easy to make a mistake otherwise:

and so on is far better.

In general, if "something" is an action that "thing" naturally knows how to do, then you should use thing.doSomething(). That's good OO encapsulation, because otherwise DoSomethingToThing(thing) would have to access potential internal information of "thing".

You only have one primary key in either case. The second one is what's called a compound key. There's no good reason for introducing a new column. In practise, you will have to keep a unique index on all candidate keys. Adding a new column buys you nothing but maintenance overhead.
