Tools like [doxygen][1] (used with the graphviz options) can generate dependency graphs for include files... I don't know if they'd provide enough overview for what you're trying to do, but it could be worth trying.

When you state "back up source code", I hope you include in your meaning the backing up of your version control system too.

If you use the runtime solution scaryjeff posted (I've done that a lot), be sure to force two garbage collections first if you want fairly accurate/consistent results, otherwise it's going to be all over the place. |

I'm guessing that watching the database for changes would be the best way to do it. That way, you could post any changes you saw happen in the FogBugz database through other Biztalk adapters.

One of the way I do it is by creating a 'Global' class with the constant values and do a static import in the classes that need access to the constant. |
The way I do it is simply:

This way at the end of the program I'm left with AddRefs() without maching Releases. No need to match pairs, |
Two things to consider are:

How to get parametrized Class instance |
|java|generics| |
Since generics were introduced, Class is parametrized, so that List.class produces Class<List>. This is clear.
What I am not able to figure out is how to get a instance of Class of type which is parametrized itself, i.e. Class<List<String>>. Like in this snippet:

If you are looking for a book, [O'Reilly][1] has a few [XML book][2]s. Since I had picked up XML on the job, I just went with [XML in a Nutshell][3] for use as a reference.

I think that FF autofills fields based on the "name" attribute of the field so that if the password box has the name="password" and the change password box has the same it will fill in the same password in both places.

It's always best to keep acquisition/release of any resource as balanced as possible.

It's always best to keep acquisition/release of any resource as balanced as possible.

I'm not sure I understand what you mean here. Do you want to know if the object is of **any generic type** or do you want to test if it is a **specific generic type**? Or do you just want to know if is enumerable?
