ListBox Extension Method for Get and Set Selected Values

Mon, 11 Aug 2008 10:28:28 GMT

ASP.Net ListBox control allows two types of selection mode: single and multiple. Working in single selection mode is similar to working with DropDown list control. Use ListBox.SelectedValue to get the value that was selected by a user. In order to set a selection SelectedIndex property can be used or Selected property of a particular item should be set to true.

BlogEngine Flaws

Tue, 29 Jul 2008 14:01:10 GMT

Recently I've been having problems as the site has gotten more popular I've had comments and even posts disappearing randomly, sometimes re-appearing you might have experienced this yourself either on my site or in your own so after divulging into the code to see what was happening found something I thought was shocking. When you add a comment, or Rating, Approving and Remove Comments this is what BlogEngine DbBlogProvider actually does...

Web developers. You suck.

Tue, 15 Jul 2008 17:46:05 GMT

Well, JavaScript developers, specifically. In order to aid in development of my own websites, I enabled JavaScript debugging in Internet Explorer a few weeks back. To my horror, I have quickly experienced what seems to be complete disregard for serving syntactically correct JavaScript on the open internet. No, I'm not just talking about a few niche websites, run by amateur programmers. I am talking about industry-leading nerd-friendly powerhouse websites that should know better.

Get Checked Repeater Items Extension Method

Tue, 17 Jun 2008 08:46:12 GMT

Imagine you have a list of some items and checkboxes next to each item providing the ability for a user to make multiple choices and submit a result in one go. Weather you are implementing a news groups subscription, user survey or online products catalogue - the code behind is the same: we bind some object list to a data control like Repeater, add a checkbox to every item, set checkbox value to item ID.

enum to friendly string extension method

Tue, 03 Jun 2008 17:01:02 GMT

We use enums quite extensively in our application as they are a great for representing integral values in a strongly typed way using symbolic names. The enum names are not very friendly to the user and I recently read a some good articles which tried to solve this problem. However, I think i've found a better solution to this problem using extension methods.

SCOPE_IDENTITY() return the id from the database on insert

Fri, 23 May 2008 16:16:03 GMT

As a .NET programmer most of my time is spent coding in C# and I try to avoid writing SQL where possible. Recently I had to write an insert stored procedure and needed to return the ID of the row I was inserting. While writing my usual bad SQL I came across a fascinating function I've never used before, SCOPE_IDENTITY().

A recreation of Python collection slicing in .NET using extension methods.

Why can't you have handlers with multiple paths in web.config

Tue, 06 May 2008 16:34:04 GMT

I have created IIS7 asset handler for my application which deals with images and stylesheets by serving them from a CMS database. For some reason the new IIS7 handlers section doesn't allow multiple paths for a handler, so you have to map each path like so...

A C# Operator I would like to see.

Wed, 30 Apr 2008 14:46:03 GMT

You could argue there are too many operators in C# as it is; however, I feel having an acute knowledge of the available operators is like knowing CTRL + B will bold the selected text in most word processing software. To put it simply, it hurts no-one, whilst providing shortcuts to advanced users...

Implementing Generic Caching

Tue, 29 Apr 2008 08:46:02 GMT

I develop for a large, high-availability website, with hundreds of thousands of daily users. As such, we need to cache a lot of data in our web-server memory (which is cheap) to save numerous hits to our main database cluster (which is very expensive). I would imagine the desire to improve performance by saving on database hits is common across many web applications - and caching frequently used data is often seen as one of the best ways to solve this problem.

Being a "nice" programmer

Fri, 25 Apr 2008 04:16:02 GMT

Being a C# developer by trade, I naturally spend a lot of my working life programming computers. Whilst I by no-means profess to be a "guru" of any kind, I do notice that there is one aspect of software development that is often neglected from discussion, and most programmers will hopefully agree with me as I explain.

How to Expose Your Collections Safely

Thu, 10 Apr 2008 13:16:05 GMT

We use collections all the time. Many times we have to expose them to users of our classes. How to expose collection safely so no one can change them outside your class?
