One primary need I have for late static binding is for a set of static instance-creation methods.

[Google Charts](http://code.google.com/apis/chart/) is an excellent choice if you don't want to use Flash. It's pretty easy to use on its own, but for Rails, it's even easier with the [gchartrb](http://badpopcorn.com/blog/2008/09/08/rails-google-charts-gchartrb/) gem. An example:

I've used both wxWidgets and QT professionally. Both are certainly capable of meeting your goals. Which one is easiest is hard to say.

How to use stored procedures within a DTS data transformation task? |

I have a DTS package with a data transformation task (data pump). I’d like to source the data with the results of a stored procedure that takes parameters, but DTS won’t preview the result set and can’t define the columns in the data transformation task.

In C++, there are three *distinct* character types:
- `char`
- `signed char`
- `unsigned char`
If you are using character types for *text*, use the unqualified `char`:
- it is the type of character literals like `'a'` or `'0'`.
- it is the type that makes up C strings like `"abcde"`

UTF-8 works well for most small character sets (except the ones allocated on high code pages), and UTF-16 is great for two-byte character sets.

For any given language, your bytes-per-character rates are fairly constant, because most languages are allocated to contiguous code pages. The big exception is accented Latin characters, which are allocated higher in the code space than the unaccented forms. I don't have hard numbers for these.

Options:
1. Use a SocketAppender to send all logs to 1 server directly. (This could serverly hamper performance and add a single point of failure.)
2. Use scripts to aggregate the data. I use scp, ssh, and authentication keys to allow my scripts to get data from all servers without any login prompts.

One use of the Java "interface" is to allow strongly-typed mixins in Java. You mix the proper superclass, plus any additional methods implemented to support the interface.
Python has multiple inheritance, so it doesn't really need the interface contrivance to allow methods from multiple superclasses.

How should I write code with unique sections for differnt versions of .NET |

My source code needs to support both .NET version 1.1 and 2.0 ... how do I test for the different versions & what is the best way to deal with this situation.

As others have said, just set the Identity option. |
I would be asking the question of WHY you have to maintain two code bases, I would pick one and go with it if there is any chance of it.
Trying to keep two code bases in sync with the number of changes, and types of changes would be very complex, and a build process to build for either version would be very complex. |

It's printing just "Array" because when you say
echo "$_GET[$field]";
PHP can't know that you mean `$_GET` element `$field`, it sees it as you wanting to print variable `$_GET`. So, it tries to print it, and of course it's an Array, so that's what you get. Generally, when you want to echo an array element, y... |
You can use:

A **little** more elegant, perhaps. |

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

You could make the Location smarter over time using Regexes if you want. |
