    How To: Strongly typed values for your TextBoxes

    Very often you need to parse/convert TextBox Text property value to some other type however I’ve never seen any universal approach for this so far… and I’m offering you one :) using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI.WebControls; public static class TextBoxExtensions { public static T Value<T>(this TextBox textBox) { return (!String.IsNullOrEmpty(textBox.Text))? ChangeType<T>(textBox.Text) : default(T); } public static T ChangeType<T>(object value) { return (T)Convert.ChangeType(value, Nullable.GetUnderlyingType(typeof(T)) ?? typeof(T)); } } It's simple, isn't it? :)...

    How do I pause execution in JavaScript?

    The current article is taken from javascript.faqts Contributors: ha mo, Daniel LaLiberte, Brent Boyer, Martin Honnen, mercury rising,   There is no true wait, sleep, or similar function in either the core JavaScript language or in client side JavaScript. Client side JavaScript however provides     setTimeout('js code here', delayInMilliseconds) which allows you to schedule execution of piece of script and setInterval('js code here', intervalInMilliseconds) which allows you to periodically execute a piece of script. So if you wanted (pseudo code) statement1;  wait (someDelay);  statement2;  you would stuff the code into functions: function statement1 () {      // your code here  }  function statement2 () {      // your code here  }    and call statement1();  setTimeout('statement2()', someDelay);      If you wanted (pseudo...
