I've had a review copy of Jeffrey Richter's CLR via C#, Third Edition for some months, and it has taken until now to get round to publishing my thoughts on the book. It's not my fault. I blame the book. It made me forget why I was given a copy in the first place. Let me explain...

Here's something that comes up often in forums - How To Find Yesterday in SQL or C#. Piece of cake, if you know how, but tricky if you don't. And especially tricky to get the right value if you are not clear on the requirement.

Following on from the recent spate of extensions methods I've posted, here's another I use to convert URLs and email addresses into links within HTML. You may want to restrict users from submitting HTML tags via forms in your application, which means that URLs and email addresses that they submit appear as plain text unless they are subjected to some kind of processing.

A common question in the forums is how to highlight key words found in search results. Here's an extension method that does that, both for partial matches, or whole word matches.

Displaying the first n characters of a block of text on a page without chopping words off halfway through is a common requirement. There are a number of ways to achieve this, but here's an extension method that you might find useful.

The most recent addition to my Cheat Sheets features details of all the Exceptions that can be found in the most commonly used assemblies within ASP.NET development. Compiling this information was an interesting challenge. I could have simply copy-pasted from MSDN, but that would have been extremely tedious. Instead, I ended up with a blend of Linq to XML, Reflection, a dash of Regex and the Global Assembly Cache Tool - gacutil.exe. Here's the full story.

Here's a list of Exceptions that can be found in the assemblies which are most commonly used in ASP.NET development. Ideally, you should be as specific as possible when catching or throwing Exceptions. The more specific you are, the less work the CLR has to do in locating the appropriate catch block, and the more informative your error messages are, which should help speed up identifying the source of any problems.

Since my article on using parameters for Preventing SQL Injection In ASP.NET, I have had a few emails asking how to do the same with an IN clause expression. In this entry, I explore a couple of ways to do this.

Delegates in C# cause a fair amount of confusion, but with the introduction of LINQ to SQL and the profilic use of the Lambda Expression operator (=>) that it has foisted on an unprepared batch of beginners, an understanding of how these two items are related, together with Anonymous Methods becomes more important. Most definitions of Delegates that you find start off with comparing them to "function pointers in C or C++", which is great if you ever worked with those languages and understood them, but not helpful to new programmers. Here's my attempt at simplifying the various concepts.

I have now covered many of the basics involved in generating PDF files from ASP.NET using iTextSharp in the series of articles listed below. This article will look at additional ways to provide formatting to documents through the use of columns.

The previous iTextSharp article looked at bringing images into a PDF file and working with them. Sometimes, however, you may want to draw shapes and lines within the PDF and not rely on images. iTextSharp includes a lot of functionality that covers simple drawing to quite complex shapes. This article gets you started. Previous articles are listed below:

The seventh article in my iTextSharp series looks at working with images. This article builds on the previous six which are listed below.

Tables will probably be one of the most used elements in PDFs generated from ASP.NET applications to provide the structure for documents such as orders and invoices. This overview is not an exhaustive examination of tables, but provides an introduction to working with them through iTextSharp, and builds on the previous articles in this iTextSharp series:

Over the years, I have picked up and read many Beginners books that attempt to get someone started on the road to building web sites with ASP.NET. Nearly all of them assumed that their readers know more than they might. Some of them seem to assume that all readers are upgrading from one version of the .NET framework to another, while others assume that you already know about core web development technologies such as HTML, CSS, C# or VB etc. I well remember being frustrated with my first book, in that it didn't give me enough basic information to get started with web development, let alone web development with ASP.NET. Now, up steps Imar Spaanjaars, with his effort: Beginning ASP.NET 3.5 in C# and VB (Wiley/Wrox, ISBN: 978-0-470-18759-3).
