In these days all web2.0 apps make use of AJAX to save bandwidth, user time or to display data without refreshing the page. When you make an AJAX request the response could be plain text, Html or JSON, but if you want to make a cross-domain AJAX call you can’t because the browser security model dictates that XMLHttpRequest must have the same domain in order to communicate. This is where you need to use JSONP, this technique will make the AJAX call and after will inject the response in a script tag and will pass the data to a specified function.
Some JavaScript Libraries help you dealing with JSONP and in this article I will show you how to make cross-domain AJAX calls with MooTools and jQuery.

After spending some time in searching more info about how to […]
As we already discussed in a previous article we started to rewrite one of our custom ASP Controls in order to improve server and network load. During this process we transformed most of old JavaScript functions to jQuery. Please bear in mind that the objective was not to improve script performance and jQuery scripts may […]
In this article we will take a brief look at the Oracle SQL FIRST/LAST aggregate functions that allow you to select a value from the first or last row(s) of a sorted group, when the needed value is not the sort key. For example consider a table “PROJECT_COST” having the following structure and data:
The Visual Studio Code Snippets feature allows very simple, common, code blocks to be reused without requiring the same thing to be typed out repeatedly, or copied and hacked. The Code Snippets feature allows inserting code, wrapping existing code and replacement of key parts of the Snippet.
