After working with .NET's HttpWebRequest/Response objects, I'd rather shoot myself than use this to crawl through web sites. I'm looking for an existing .NET library that can fetch URLs, and give you the ability to follow links, extract/fill in/submit forms on the page, etc. Perl's LWP and WWW::Mechanize modules do this very well, but ...
Yes, many web developers live and breathe HTML, but there are still tags and tricks that aren't used as often as they could be. What are some of your favorites? ...
I've seen a few sites that list related searches when you perform a search, namely they suggest other search queries you may be interested in.

Selenium Remote Control has a method of "get_html_source", which returns the source of the current page as a string. AFAIK, this method works in all cases in Firefox and Safari. But when it's invoked in Internet Explorer, it returns an incorrect source. Does anyone know if this is a bug with Selenium or Internet Explorer, and if there'...

I have an Access 2003 application that communicates with a Webservice to get articles from a central database. It runs fine in a full Access install but when I make runtime install with Package Wizard included in Access 2003 developer extensions, it fails with the error message "429 cannot create an object in the active-x component" The ...
Due to a lack of response to my original question, probably due to poor wording on my part. Since then, I have thought about my original question and decided to reword it, hopefully for the better! :) We create custom business software for our customers, and quite often they want attachments to be added to certain business entities. F...
We need to test a website in both IE6 and IE7. We've had bugs appear running on actual windows machines that aren't visible under vmware (?!), so we have an actual windows laptop to do this - but only one. Is it possible to install IE6 and IE7 side-by-side in such a way that they absolutely, positively, behave exactly like they would if ...

On one page, currently I have to hit Enter to go to the next page, but it's not on a submit button, it's captured manually. This is not picked up by the recorder. I know I can enter it manually myself after recording, but why isn't this part of it? ...
Wrong answer was autoselected by the stupid bounty system. I'm using front page extensions to interact with SharePoint Services 3.0 as described here. In most samples I have seen the client simply looks for particular English strings in the result and uses that to determine if an error has occurred. However, I am writing an application...
