I was generating empty XML templates when I ran into a bit of a challenge: I had to generate 30 "category" nodes that were, basically, dates, and also empty data values for each of those dates. The trick was that the dates had to be based on the day the Chart was accessed.Well, to be fair, it http://blog.diegocadenas.com/2009/07/range-and-linqtoxml.htmlnoreply@blogger.com (Diego Cadenas)0tag:blogger.com,1999:blog-881982293208471467.post-30347504146014020Mon, 13 Jul 2009 17:31:00 +00002009-07-13T12:51:58.082-05:00linqToXmlvb.netrssFeedlinqI needed to display some RSS feeds into a dashboard page in one of our websites. I figured I had to mess with XML, XPath, etc.. to browse the xml structure of the post. However, LinqToXml turned out to be the perfect tool for this task. I used Scottgu’s post as a reference, but did my own little twist at the end to avoid another “loop” First, pass the Rss feed Url into an Xdocument variable: http://blog.diegocadenas.com/2009/07/consuming-rss-feed-using-linqtoxml.htmlnoreply@blogger.com (Diego Cadenas)0tag:blogger.com,1999:blog-881982293208471467.post-2398204465001848090Sat, 19 Apr 2008 03:28:00 +00002008-04-18T22:30:06.521-05:00humorhttp://blog.diegocadenas.com/2008/04/chicken-chicken.htmlnoreply@blogger.com (Diego Cadenas)0tag:blogger.com,1999:blog-881982293208471467.post-2131915556541148751Tue, 08 Apr 2008 21:16:00 +00002008-04-10T08:51:34.505-05:00asp.netQuerystringI was browsing through the Page class in System.Web.UI assembly and I run into the "ClientQueryString" property.

The most common one is Server.HtmlEncode or System.Web.HttpContext.Current.Server.HtmlEncode.  The Server Object is an instance of the System.Web.HttpServerUtility Class and it is readily accessible through any .aspx page since they inherit from the Page object whichhttp://blog.diegocadenas.com/2008/03/serverhtmlencode-vs-httputilityhtmlenco.htmlnoreply@blogger.com (Diego Cadenas)0tag:blogger.com,1999:blog-881982293208471467.post-4836452748836033304Thu, 29 Mar 2007 16:39:00 +00002007-03-29T12:02:14.530-05:00videostechnologyI was visiting wollzelle's blog page and I came accross this REALLY cool video.

After googling a little, I found MSN's sample code for FTP using the new FTP classes in 2.0. Here is a link to the Microsoft Download Page.

The best examples out there are Google Maps and Google Suggest. Basically Ajax lets developers create interactive web user interfaces that are comparable to desktop interfaces.
