Web Application Toolkit: Mobile Web Applications [Web Application Toolkit: Mobile Web Applications]

Jonathan Carter — Thu, 24 Sep 2009 18:04:00 GMT

This Web Application Toolkit is designed to demonstrate how to extend an existing ASP.NET MVC Web application to provide access from mobile devices. To enable mobile access, the Web application should have views targeting each of the mobile devices to be supported.

We use the MVC pattern to create several views targeting different kind of browsers reusing the same business logic. For this implementation, we use the ASP.NET MVC framework which provides an alternative to the ASP.NET Web Forms pattern for creating MVC-based Web applications. The ASP.NET MVC framework is a lightweight, highly testable presentation framework that is integrated with existing ASP.NET features, such as master pages and membership-based authentication.

For extending the Web application to use mobile specific views, this sample provides a reusable component called MobileCapableViewEngine that enables the Web application to show the appropriate view depending on the device's browser that is performing the request.

Web Application Toolkit: Template-Driven Emails [Web Application Toolkit: Template-Driven Emails]

Jonathan Carter — Thu, 24 Sep 2009 18:03:00 GMT

This Web Application Toolkit is designed to demonstrate how to generate and send dynamic, template-based emails from a web application. There are many common scenarios where notification emails need to be sent to end users. Examples of these common scenarios may involve notifying a user of their newly created account, sending a new password in respond to a forgotten password request, or emailing an alert under specific business circumstances, such as the creation of a order. Typically the E-mails sent from a Web application scenario are formatted as HTML, include CSS stylesheets, and images and need to be generated dynamically with custom or user-specific data.

This Web Application Toolkit provides a reusable component named TemplateDrivenEmail that can be used to easily generate and send dynamic, HTML-formatted emails based on templates that you can easily create and customize. The TemplateDrivenEmail component is a .NET Class Library that can easily be included in your solution and used with an ASP.NET Web Application, a background application such as a Windows Service, or any other type of .NET application. The email templates are based on a standard XML technology know as Extensible Stylesheet Language. This Web Application Toolkit also includes an example that shows how to use the TemplateDrivenEmail component.

Web Application Toolkit: REST Services [Web Application Toolkit: REST Services]

Jonathan Carter — Thu, 24 Sep 2009 18:02:00 GMT

This Web Application Toolkit shows how to easily add REST service interfaces for an existing Web application. The Web Application Toolkit includes a sample of REST services based on a fictitious online auction site. It exposes an API using REST services built with the Windows Communication Foundation that can consumed by client applications. Two sample client applications are included, one using simple ASP.NET pages to consume the REST service and show a list of ending auctions, and a second Web application using AJAX to asynchronously invoke the REST service to show a list of most viewed auctions. The Web Application Toolkit also includes a custom project template for Visual Studio to make it easier to build new REST Services.

In this episode of 10-4, we introduce a new feature coming along with Visual Studio 2010 and the .NET Framework 4.0: sentient DSLs. If you've become intrigued with all the hype around leveraging domain-specific languages, but you're concerned about the added complexity that comes with having to learn a bunch of different grammars, then sentient DSLs are for you. Write the code that you think makes sense, and allow the application to create itself. Coding should be fun, and most importantly, it should be easy.

Jonathan Carter — Thu, 05 Mar 2009 04:30:00 GMT

In this episode of 10-4, we introduce another new feature of ASP.NET WebForms 4.0: Routing. The ASP.NET Routing engine was added in the .NET Framework 3.5 SP1 release and is heavily leveraged by both ASP.NET MVC and ASP.NET Dynamic Data to provide bi-directional routing functionality. With the release of ASP.NET WebForms 4.0, you can take full advantage of the common route engine that allows you to customize the URLs that your application exposes. In addition, new expression builders allow you to generate dynamic URLs that are based on your route definitions, alleviating you from having to hard code static links.

Database design/performance question [Database design/performance question]

Jonathan Carter — Fri, 23 Mar 2007 03:10:00 GMT

I have a group of about 6 datatables that collectively CAN contain millions of records (it is based on the user). Users have the ability to create a personal version of the data contained in the 6 tables so that they can modify/add/delete/whatever they want to the data to perform "what-if" scenarios and not affect the live data. The design originally placed a column in all 6 tables called VersionID that was part of the respective primary keys, allowing each record in all 6 tables to be replicated with a modified version identifier. So when a user created a new version, it would copy all data in each table, apply a new VersionID value to the data and re-insert it into each table.

This solution seems to be pretty crappy in terms of performance/design.

1) The tables get cluttered with tons of data that is user created.
2) The tables record counts get blown out of whack if excessive versions are made, which in turns kills performance.
3) In order to use these tables with any sort of effeciency, an index needed to be put on the VersionID column to allow for selecting of records by it, but adding that index affected the other non-version related operations on each table.
4) Other issues...

My question is: what would be a better approach to this solution? Would it be better to create a copy of each of the tables for each version? So that the data would be seperated and data operations would perform better since each version would be isolated. Plus when the version is deleted later, I could easily perform DROP TABLEs on each copy which would be basically instant and wouldn't jack the index of the live tables with deleting millions of records.

Any input is appreciated.

SessionPageStatePersister [SessionPageStatePersister]

Jonathan Carter — Thu, 22 Mar 2007 22:40:40 GMT

Has anyone developed a decent sized application that used the SessionPageStatePersister as opposed to the default HiddenFieldPageStatePersister? If you had a web app that was getting hit pretty severely, I wonder what would produce better performance results.

Thanks in advance for any thoughts.

Table/Stored Procedure naming conventions [Table/Stored Procedure naming conventions]

Jonathan Carter — Sun, 11 Mar 2007 18:01:19 GMT

In line with w3bbo's thread on form control naming conventions, I'm curious as to what conventions you all follow when it comes to naming your database tables and stored procedures.

1) Do you name your tables singluar or plural?
2) Do you prefix your table names with anything?
3) Do you name your stored procedures based on the table they are associated with or by the domain they reside in?
4) What do you prefix your stored procedures with?
5) ect.

I've seen just about everything done, and am interested to see what some of the bigger brains of Channel9 have been doing.

Observation from the two latest ASP.NET AJAX videos [Observation from the two latest ASP.NET AJAX videos]

Jonathan Carter — Fri, 23 Feb 2007 04:54:41 GMT

I was watching the latest videos posted on ASP.NET's website (just for kicks) and I noticed that the guy giving the examples is terribly inconsistent in his coding style. Sometimes he uses hungarian notation, other times he doesn't. Some places he uses single quotes, and double quotes in others. He camel cases some of his function names and Pascal cases others, ect...

Not that I really care, but you would think a seasoned developer would have established a preference for doing such trivial things.
