Importing Textpattern to WordPress 3.5 (January 31st, 2013)

I was looking to import an old site running Textpattern v4.2.0 to WordPress 3.5.1. I found this crappy plugin which never worked. So I had to find another easy way. RSS should work.

Figuring Out Connection Pool Errors (October 1st, 2012)

This is the error I had to go on. System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. It sounds pretty obvious that it is a database connection that was not being […]

jQuery Custom Events (January 18th, 2012)

We are used to javascript events such as a “click” being handled similar to the following: $(‘#id’).on(“click”, function() { alert(“Item clicked”); }); But less common is the use of custom events available with the .trigger() and .triggerHandler() jQuery functions. With this I could create an event such as “cory.says.hello”, if I so wished and then […]

HTML5 Placeholder in IE and Unsupported Browsers (December 9th, 2011)

The html5 placeholder attribute on an input tag is a really nice, however easily adding that feature to older IE versions and any other browsers that don’t support it renders it unusable in production.

WordPress Multiple Sidebars (October 13th, 2011)

Seems there are a lot of complicated ways to add multiple sidebars to a wordpress theme, so here is a simpler one. Add this to your functions.php file for the theme. add_action( ‘widgets_init’, ‘add_sidebars’ ); function add_sidebars() { register_sidebar( array( ‘id’ => ‘right’, ‘name’ => __( ‘right’ ), ‘description’ => __( ‘Right Sidebar’ ), ‘before_widget’ […]

WordPress 3+ allows for custom theme controlled menus. For this example I will be adding 3 but the same works for 2, 3 or any number of wordpress menus. In the functions.php file of the theme we first need to add support for menus. if (function_exists(‘add_theme_support’)) { add_theme_support(‘menus’); } The function_exists is only there for […]

Validation ($SCHEMA$): Element ‘html’ and ASP.NET 2010 (April 8th, 2010)

I finally got fed up with “Warning Validation ($SCHEMA$): Element ‘html’” enough today that I spent some time to figure out what was causing all the warnings on every html or even <asp> tag I had in my .aspx pages. Every time I would build my project I would get tons of warnings such as […]

jquery to solve the 100% height problem (January 12th, 2010)

Real short post today just a quick snippet of jQuery that solves the 100% height problem. Yes there are complete CSS solutions to this but it seems that at times they can be problematic, and at other times laziness can kick in. $(document).ready(function () { $(“#divID”).height($(document).height()); }); //And the slightly more fancy way. With a […]

Input Data to Display Newlines in ASP.NET (February 14th, 2009)

In asp.net input taken from a plain text box will not display newline characters (Hitting the enter key) when outputting to the browser. So for example you have a text box that users can input text into, they put a couple paragraphs in it and submit that data to the database. If you just strait […]

List Images (January 31st, 2009)

In CSS List Images are such a simple topic that I have seen overlooked over and over. There is not much to it at all. Just one line of css. Example ul { list-style-image:url(picName.jpg); } Done in one short line. This will simply make every un-ordered list have an image in place of the dot. […]

WordPress Paging Style (April 16th, 2008)

Recently Jens Törnell over at http://www.jenst.se/ wrote a plugin that “I made a paging navigation plugin for WordPress that will be an alternative to the “Next page” and “Previous page“.
