ASP.NET MVC is not all about Linq to SQL

calendar_today 21 February 2010 08:21

ADO.NET ASP.NET MVC

Pretty much every sample application that illustrates ASP.NET MVC uses Linq To SQL or the Entity Framework as the data access method. I've seen a number of questions posted to the forums at www.asp.net asking if there are any alternatives, and indeed there are. This article will look at using plain ADO.NET within a data access layer to provide dynamic content to a typical small CRUD application.

Using gacutil.exe and Reflection to generate the Exceptions Cheat Sheet

calendar_today 10 February 2010 07:28

C# Visual Studio General ASP.NET 3.5

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.

Cheat Sheet - .NET Framework Exceptions

C# General ASP.NET 3.5

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.

ASP.NET MVC

Have you ever noticed an unusually high number of requests in your web server log files for image files? It may well be that someone is linking to your images from their own site, and basically stealing your bandwidth. Here's how to implement a custom RouteHandler within an ASP.NET MVC application to prevent people leeching your images.

ASP.NET MVC Uploading and Downloading Files

calendar_today 21 December 2009 22:29

ASP.NET MVC

If you come to ASP.NET MVC from a purely ASP.NET Web Forms background, one of the first things you are likely to notice is that all those nice easy Server Controls have disappeared. One of those is the FileUpload, and its absence seems to cause a few problems. This article looks at how to upload files to the server in an MVC world, and how to get them back from the server to the user again.

Some one posted a comment to one of my articles the other day.  It appears that they had had little success in adapting some code I had posted in the article to their application. They included this phrase in their comment: "Please advice me, it is  urgent".

Storing Files and Images in Access with ASP.NET

calendar_today 06 December 2009 19:46

MS Access ASP.NET 3.5 ASP.NET Web Forms

Should you store files and images in the database or the filesystem in an ASP.NET application?  With SQL Server this is a dilemma, with both approaches having their pros and cons.  When it comes to Access, the decision is much easier to make.  Because an Access database is restricted to 2Gb, it makes more sense to store files in the file system.  However, sometimes, you may not have the choice. If you have to use the database, here's how.

Simple File Download Protection with ASP.NET

ASP.NET 3.5 ASP.NET Web Forms

When it comes to protecting files from unauthorised downloading, the vast majority of articles offer solutions that involve mapping common file types (.pdf, .txt, .doc etc) to ASP.NET within Internet Information Services.  However, often in a shared hosting environment, you don't have access to IIS and the hosting company will not agree to providing such mappings for you, so what do you do?

Book Review - Professional Enterprise .NET

ASP.NET 3.5 ASP.NET MVC Book Review

I reviewed an ASP.NET Architecture and Design book recently. It was OK. I felt it was a bit thin, and didn't cover topics beyond beginner level. Then I got sent a review copy of another book: Professional Enterprise .NET. Having read it, this is the book that the previous book should want to be when it grows up.

Book Review - ASP.NET 3.5 Application Architecture and Design

General ASP.NET 3.5 Book Review

Back in the day, when I began to get interested in ASP.NET application architecture and design, I spent hours hunting for a book that would explain all I needed to know.  I wanted one that focused on ASP.NET, with its special demands, rather than a general .NET development book.  I wanted a book that would explain what layers and tiers were, and how I should separate code out to make it more scalable and reusable.  I wanted a book that would explain how I could take my skills to the next level. I couldn't find one.  There was a big gap in the market.  Vivek Thakur has attempted to fill this gap, with this apty named title: ASP.NET 3.5 Application Architecture and Design.

LINQ ASP.NET MVC Entity Framework

As you delve more into ASP.NET MVC you start to come across a whole new way of doing things that Web Forms development didn't really expose you to. Inversion of Control (IoC) and Dependency Injection (DI) are two phrases that crop up a lot in the MVC space. So what are they all about? And should you care?

If you are developing a business application using ASP.NET MVC, and need to produce some kind of dashboard-style reporting, the Chart Controls from Microsoft are a good place to start.

SQL ADO.NET ASP.NET 3.5

I, and many other contributors to the forums at www.asp.net find examples of code posted on a daily basis that are vulnerable to SQL Injection attacks. We continue to exhort beginners (and some more experienced programmers) to code against them. This article examines just how serious a flaw vulnerable coding can be, and what you should do about it.

ASP.NET MVC - Battle of the Books

calendar_today 27 July 2009 13:25

General ASP.NET MVC Book Review

There's always a splurge of new books that come out around the RTM of any new ASP.NET related technology. Authors all over the place are burning the midnight oil, cursing the changes from one CTP to the next, through to Betas and hoping against hope that the Release Candidates and final RTMs aren't stuffed with "breaking changes" which inevitably mean total rewrites of whole sections or chapters in their draft. And then the race between the publishers is on, as each tries to get their offer to market before the others. Here, I look at three of the titles that were published around the time that ASP.NET MVC was launched, and give my judgement on how they fare in covering not only the core Framework but the key features that ASP.NET MVC is designed to offer:
