Initial validation on dynamically added control

WPF validation system performs intial validatation of an object (I mean - all fields are validated when a databound item is changed, and results are displayed on the ui). But it doesn't work like this, when I add a control dynamically. In such case inital validation happens, but results aren't shown on the ui. Only after some properties ...

Easy way to test a URL for 404 in PHP?

I'm teaching myself some basic scraping and I've found that sometimes the URL's that I feed into my code return 404, which gums up all the rest of my code. So I need a test at the top of the code to check if the URL returns 404 or not. This would seem like a pretty straightfoward task, but Google's not giving me any answers. I worry I...

Does W3C validated CSS automatically mean cross-browser compatibility?

I've finally completed a working version of my first ever CSS-supported site (thanks to some very helpful suggestions on this forum) and have validated the CSS. Before I go out and find (buy?) another machine (I'm a Mac) to check IE on, is it remotely possible that the valid CSS is really truly valid on IE as well as Firefox, Safari tha...

In C# check that filename is *possibly* valid (not that it exists)

Is there a method in the System.IO namespace that checks the validity of a filename? Example: 'C:\foo\bar' would validate ':"~-*' would not a little trickier: 'X:\foo\bar' would validate is there is an X: drive on the system, but wouldn't otherwise. I suppose I could write such a method myself, but I'm more interested in a built-in on...

ASP.NET broken rendering of Validation client side code in Firefox

I'm using a bunch of different asp.net validation controls on a web form. Some of these have their Text property set to things like "* Error" or "You missed these fields".

Dynamic DateTimeRangeValidator using Enterprise Library 4.1?

I'm trying to add a range of - 365 days and + 365 days but it appears that using this attribute in EL 4.1 only accepts a special ISO formatted string ... thus I can't simply add a normal string to this validation routine. <DateTimeRangeValidator(DateTime.Now.AddDays(2), DateTime.Now.AddDays(4))> _ I wanted to do something similar to t...
