Creating Graphics On-the-Fly in ASP.NET

Creating graphic for use in your web page is a snap in .NET. In this example I will be using VB.NET to create a graphic file for use in a page. Since this graphic will be hosted in an Image server control you will have full access to placement, sizing and other properties.

Creating HttpHandlers and HttpModules

Http handlers are special applications that typically handle files with certain extension. For example when you request a file with extension .asp IIS routes it to ASP processor. But what if I want to handle files with my own extensions say .bipin? Http handlers allow us to do just that. Now, you might be thinking what is the use of a new file extension? Consider a case where you want to generate graphics on the fly. In such cases you will write an Http handler that will do your task. Note that Http handlers are typically called for the specific file extensions they are designed for. If you have worked with ISAPI extensions in past you will find this concept very familiar.

Developers can quickly create their own controls and extend the API as they want! In this article we will see how to create our own Windows Form User Control to help us create a new 'LabledTextBox' control.

Creating Your First C# Windows Application

Creating Your First Code Behind Page

C# appears to be the new language of choice around the development community, or at least the most talked about new language. Microsoft has introduced a language that will (hopefully) bring together both Visual Basic developers and Visual C++ developers alike. It is important to remember that this application is only to show you some of the most basic compenents in C#. Here we will design a form that will allow a user to populate a listbox with customer names they type above.

New to ASP.NET? Confused about 'code behind'? Don't have Visual Studio.NET yet? Read on for answers to your questions.. Like You, even I haven't got a copy of Visual Studio.NET Beta2, but then we read everywhere about ASP.NET's capabilities to separate the design and logic, is it possible without Visual Studio.NET? Yes, it is and I will show you how easy it is.

When building any application, be it a web application or a desktop application, handling errors gracefully is essential. Users don't want to see a stack dump or what line of code the application crashed at. This is why we provide custom error pages for users. This also gives us a method of tracking errors that users cause. This tutorial will give you an overview on how custom error handling is done. It will also provide you with some code which you can use to create your own custom error pages for your web applications.

Custom Errors in ASP.NET

.NET Xtreme

When a runtime or design-time error occurs in an application, ASP.Net shows a default error page that gives a brief description of the error along with the line number on which the error occurred. A developer would wish to view this default error page, during the testing of the application since the description helps him in rectifying the error. But he would never want a user trying to access his application, to view this error page. The user would be least bothered to know about the error. Instead of showing the default error page, it would be more sensible to show a customized error page that would let the user send notification of the error to the administrator.

Custom Permissions

C#Today

Any multi user system needs to have a concept of security to protect one users data from another. This security element could be anything from granting or denying a user access to a file, a network share, or certain entities in a database. These security mechanisms are controlled via the use of Permissions. Before the advent of .NET, using permissions in application code was hard, but now the framework allows a very open and extensible permission architecture. In this article, the third of the week's security-based articles, Kaushal Sanghavi explores the support that the .NET framework offers for working with permissions, and demonstrate how developers can design their own custom permissions to control access to protected data.

C#Today

In the previous articles in this series, we have discussed the security architectures and schemes available to developers in the .NET framework. Code access security and role based security are the two main types of security available to developers. In this article, Kaushal Sanghavi explores .NETs support for building a custom security scheme by implementing our own identity and principal classes that rely on user information stored in a database. In the previous article on Custom Security Permissions, we focused on Code Access Security, while in this article we focus on extending .NETs support for Role Based Security.
