For a 3x3 system of linear equations I guess it would be ok to roll out your own algorithms.

Are you just talking about the interface and storage, or the implementation of sending the emails as well?
Yes, a SQL table with FROM, TO, Subject, Body should work for storage and, heck, a textbox or even maybe a RichText box should work for editing.
Or is this a web interface?
For actually sending it, check ... |
From a high level, yes. :D The main thing is some place to store the templates. A database is a great option unless you're not already using one, then file systems work fine.
WSIWIG editors (such as fckeditor) work well and give you some good options regarding the features that you allow.

In access I never figured out how to properly use the OLE object data type without real performance problems (and structural too -- lots of compact and repair jobs).

If the Java way is the OO way, then yes, creating a class with public fields breaks the principles around information hiding which say that an object should manage its own internal state.

Just an idea: Mapping the hostname to 127.0.0.1 in the hosts ($WINDOWS$\system32\drivers\etc\) file may help. This way you should be able to pull up the local IIS site by typing the hostname as if it's a remote server |
Maybe I am not understanding the question, but what's wrong with just typing in the URL for the website? If it's the matter of domain name resolution, you can point to the right DNS or put it in [hosts][1] file.

In the markup after the image, insert something like `<div style="clear:left"/>`. A bit messy, but it's the easiest way I've found.
And while you're at it, put a bit of margin on that image so the text doesn't butt up against it. |

I'd say that the best way of solving this is to use Aspect-Oriented Programming (AOP). Mats Helander did a [write up on this on InfoQ][1]. The article is a bit messy, but it's possible to follow.

Structs are just like classes that live in the stack. I see no reason why they should be "unsafe". |
There are no consequences to a struct implementing an interface. For example the built-in system structs implement interfaces like `IComparable` and `IFormattable`. |
Does generated code need to be human readable? |
|language-agnostic|code-generation|readability| |
I'm working on a tool that will output an interface and a couple classes implementing that interface. My output isn't particularly complicated, so it's not going to be hard to make the output conform to our normal code formatting standards. But this got me thinking: how human-readable does auto-generated code need to... |

I guess a simple but probably non optimized algorithm is to

If my language of choice didn't offer of way to do this without thinking then I would initially consider two options as the easy way out:

Perhaps it's easier to see the problem with an example:
Animal dog = new Dog();
dog.SetLeg(new CatLeg());
Now that should compile if you're Dog compiled, but we probably don't want such a mutant.
A related issue is should Dog[] be an Animal[], or IList<Dog> an IList<Animal>? |
The important thing to remember is that you can use a derived type every place you use the base type (you can pass Dog to any method/property/field/variable that expects Animal)

I would highly recommend using something like jquery where this is trivial:
$("#someId").addClass("newClass);
so in your case:
$("p[height='30']").addClass("h30");
so this selects all paragraph tags where the height attribute is 30 and adds the class h30 to it. |
