Wednesday, May 06 2009

Here are 10 of the pitfalls that litter the path to releasing your production ASP.NET applications, and what you can do to avoid them. O ne of the reasons ASP.NET is successful is that it lowers the bar for Web developers. You don’t need a Ph.D. in computer science to write ASP.NET code. Many of the ASP.NET people I encounter in my work are self-taught developers who wrote Microsoft Excel spreadsheets before they wrote C# or Visual Basic.Now they’re writing Web applications and, in general, they’re doing a commendable job. But with power comes responsibility, and even veteran ASP.NET developers...

An example of how we can make a request to a web page and retrieve the resulting HTML Summary: An example of how we can make a request to a web page and retrieve the resulting HTML There are a few situations where it would be useful to be able to retrieve the HTML from a web page via code. Fortunately, this is made relatively easy by the HttpWebRequest and httpWebResponse classes. Firstly, we need to decide which type of form the web page is using.

Multithreading in ASP.NET : Richard Bean

Sunday, May 03 2009

Explains how to use threads to enable multitasking in ASP.NET 2.0 applications. Performance and responsiveness are most the important key issues in the success of your web application. Do not relay heavly on your users to be patient. They typically quickly close unresponsive or frozen applications. Sometimes you need to perform a long time task, that uses intensive CPU operations. Sometimes you are acquiring a database and waiting for the results. Not to mention when you are performing an intensive I/O operations. As a result your, application will be dead with no response until this time consuming...

User Administration Tool (Part 3) : Bipin Joshi

Saturday, May 02 2009

In Part 2 of this series we covered user management features. This final part will deal with role management and profile management. The code gets a list of all the roles defined in the system by calling GetAllRoles() method of the Roles object. The returned roles are supplied as a parameter to a method called FillControlsWithRoles(). This method is discussed shortly and simply fills the CheckBoxList and DropDownList with the roles. The code then proceeds to retrieve a list of roles belonging to the user. This is done by calling GetRolesForUser() method of the Roles object. The for loop iterates...

Using Existing Stored Procedures for the Typed DataSet’s TableAdapters : Scott Mitchell

Thursday, April 30 2009

In this tutorial we learn how the same TableAdapter Wizard can work with existing stored procedures. We also learn how to manually add new stored procedures to our database. In the preceding tutorial we saw how the Typed DataSet’s TableAdapters could be configured to use stored procedures to access data rather than ad-hoc SQL statements. In particular, we examined how to have the TableAdapter wizard automatically create these stored procedures. When porting a legacy application to ASP.NET 2.0 or when building an ASP.NET 2.0 website around an existing data model, chances are that the database already...

ASP.NET Request Logging with Asynchronous Fire And Forget Pattern : Peter A Bromberg

Monday, April 27 2009

Shows how to perform high-speed ASP.NET Request logging to a database using the asynchronous Fire and Forget delegate wrapper patterns. In wiring up a recent article about Request Logging to feature a couple of tricks I've learned in my short happy career as a .NET programmer, I revisited the Fire And Forget pattern and decided to add this into my code to make it even faster. Fire And Forget using a "self completing delegate wrapper" is something I first came across on Mike Woodring's page, and I've written about it several times here. Jon Skeet also has an implementation, which I think is even...

For example, user name entered on login page getting displayed in welcome message on homepage. How do you generally post values/data from one page to another page in ASP.NET 1.x? There are different ways in which you can exchange the data in ASP.NET 1.x like Query strings, Server.Transfer method, Response.Redirect method and session variables. All these techniques have their own merits and demerits like browser imposed character...
