If your personal project is similar to an existing open source project, you should consider contributing to that project instead. A couple of small contributions (bug fixes etc.) are
more valuable than a half finished project. |
I find there are lots of limitations to CSS that just seem to hint the specification designers don't make websites for a living.
Use HTML tables if you can't do it easy in CSS.
Having said that, some of the frameworks do help and it always nicer to do in CSS if you can manage it. |

While for most datetime operations I would normally convert to Unixtime and perform addition subtraction etc. on the Unixtime integer, you may want to look at the Zend framework Zend_Date class.

Old-school SQL DB access versus ORM (NHibernate, EF, et al). Who wins? |

You can almost do it like this:
static void TestException<E>(string message) where E : Exception, new()
{
var e = new E();
e.Message = message;
throw e;
}
However, that doesn't compile because Exception.Message is read only. It can only be assigned by passing it to the con... |

You can look at the [eval][1] function in PHP. It allows you to run arbitrary PHP code. It can be a huge security risk, though, and is best avoided.

You need to pass the RegexOptions.Singleline flag in to the regular expression, so that "." matches all characters, not just all characters except new lines (which is the default). |

The reason you can't extend Enums is because it would lead to problems with polymorphism.

Page.DataBind() kicks off a round of databind on all child controls. That'll cause Asp.Net to re-evaluate bind expressions on each control.
