YUI 2.4.0 Finally Released!

Posted by on December 4, 2007 1 comment

Yesterday was released the latest version of Yahoo Javascript library – YahooUI. It’s available for download and full documentation is also online at their site.

What is new:

– Selector Utility: The YUI Selector Utility implements much of the CSS Selector syntax as defined by the W3C, including the proposed CSS3 Selector extensions.

– Charts Control: The Charts Control draws data from the same DataSource Utility that underpins the YUI DataTable Control, making it possible to do combined chart/table visualizations. The Charts Control accepts CSS style information, allowing you to skin the chart itself without touching the underlying .swf file.

– Get Utility: Get provides an interface for dynamically adding script nodes and CSS link nodes to the page.

– Profiler: Profiler allows you to target specific code for profiling and to retrieve profiling data programmatically while your application is running — in any A-Grade browser.

– JSON Utility

– Button:

– Calendar: Satyen Desai has added built-in year navigation to the YUI Calendar Control.

– Drag & Drop: If your implementation requires simple drag-to-reposition functionality, this configuration option suppresses the complex targeting and interaction logic that is the most computationally intensive aspect of drag and drop; in those cases, you’ll see significant performance boosts.

– Rich Text Editor: Dav continues to push the YUI Rich Text Editor in both size and performance. With 2.4.0, you can better control the dependency list, allowing you to shave more than 50% off the overall k-weight of the widget (vs. its 2.3.1 profile) if you don’t need some of the glossier UI elements.

Two interesting posts!

I have severe lack of time so thats the reason to blog about the following posts in one short notice. Few weeks ago I came across Matt Berseth’s blog and made me quite good impression. He blogs frequently and providing quality posts. His last two I liked a lot.

The first one was about how to create image reflections. He describes three practices:

– Browser Specific Client Side Solution
– Cross Browser Client Side Solution
– Cross Browser Server Side Solution

Which one we choose is a matter of what we really want – rendering time or support for all browsers.

Then he wrote about my favourtite IDE – Visual Studio 2008. Matt described how we can use the new ListVew control plus adding DataPager control and extend it with SliderExtender Control from AjaxControlToolkit.

This post is provided with demo and source code for download. Thanks Matt!

Converting SQL to LINQ

Posted by on December 3, 2007 3 comments

This is a series of posts regarding the new language improvements in VB 9. Bill Horst has written the second on which I came across here. As we all know VB LINQ statements enable SQL-like syntax for queries in the VB language. LINQ syntax doesn’t match SQL syntax exactly, so if you are already working with SQL or familiar with SQL queries, you may find yourself wanting to convert an existing SQL query to LINQ.

And here is an example with FROM clause:

A SQL SELECT statement always begins with a SELECT Clause, followed by a FROM Clause. A VB query expression always begins with a From Clause or Aggregate Clause (Aggregate will be discussed later). A basic SQL FROM clause specifies a table over which to query, and similarly, a LINQ From Clause specifies an object over which to query (CustomerTable). This object could represent “In-Memory” data, a SQL data table, or XML information. My examples use the “In-Memory” case, since it allows the simplest code. In addition to this data object, the VB From clause always includes an identifier for the current “row” (Contact), which basically functions as an alias.

SQL

SELECT Contact.CustomerID, Contact.Phone
FROM CustomerTable Contact

LINQ

From Contact In CustomerTable
Select Contact.CustomerID, Contact.Phone

Here is the whole post by Bill Horst.

In it training, the order of courses matters a lot. Doing 70-290 after 70-270 makes more sense rather than the vice versa. This holds true for 70-291 as well. A 642-901 should be attempted after 642 series, not something as basic as 70-297.
