Here's a sample that we used for cross-platform embeddeding of files.

JAD is an excellent option if you want readable Java code as a result. If you really want to dig into the internals of the `.class` file format though, you're going to want `javap`.

Stored procedures are better, in my view, because they can have an independent security configuration from the underlying tables.
This means you can allow specific operations without out allowing writes/reads to specific tables. It also limits the damage that people can do if they discover a SQL injection exploit. |

Not a full answer, but you **don't have to parse** your own XML. It will hurt performance and reliability.

To obtain data for given ISBN number you need to interact with some online service like [isbndb][1].
One of the best sources for bibliographic information is Amazon web service. It provides you with all bibliographic info + book cover.

Check out [ISBN DB API][1]. It's a simple REST-based web service. Haven't tried it myself, but a friend has had successful experiences with it.
It'll give you book title, author information, and depending on the book, number of other details you can use.

In our office, our CTO has categorically banned the use of the var keyword, for the same reasons that you have stated.

The Control.DesignMode property is probably what you're looking for. It tells you if the control's parent is open in the designer.

In addition to what was said, a lot of LISP goodness is based on guaranteed lack of side-effects and using built-in data structures. Both rarely hold in real world. ML is probably better functional base. |
You are allowed to make changes to the `*.aspx` file while it runs, and you can hit refresh on your web instance to see those changes immediately. However, you cannot make changes to the `*.cs/*.vb` or `*.designer.cs/*.designer.vb` files while the program runs. |

Bit shifts are usually very fast:
y = 0xFF3B * (int32_t) x >> 16;
This is probably better written as:
y = (0.997 * 0x10000) * (int32_t)x >> 16;
A good compiler will generate equivalent output.
If your integers are signed, the constants should be changed to 0x8000 and 15. |
