This article provides a fully functional code for protecting websites from unwanted visitors. The code is developed in ASP (Active Server Pages) and VBScript (Visual Basic Scripting). The aim of developing code in ASP and VBScript is because both languages are cross-browser compliant and give a more secured way to protect website content. The code runs on both session cookies (hidden cookies) and textual cookies (not the JavaScript ones). The session cookie gives more security to web content and... |

Web-based Active Directory Login implements central sign-on system for web-based applications. It was developed to eliminate maintenance of user passwords in database, whether encrypted or not. A user running application from desktop enjoys liberty to access resources and/or services on the network which he has permission to do from Windows. On the other hand, web-based applications run in a security context entirely different from that of a desktop application. Same user while running applicati... |

Although we all appreciate the need for security, there are times when you would like to avoid the need to login to a web page to view a public or corporate Mailbox/Calendar/Tasklist via Collaborative Data Objects (CDO). This code allows a user to assume the identity of an existing user, and avoids the NT challenge response prompt. It could also be used anywhere that it is desirable to allow for access to a resource accessible via NT authentication. This approach in effect simulates the provisio... |

In this article, Scott demonstrates how to log ASP.NET application shutdown events.
Someone on a listserv recently asked whether there was a way to figure out why and when ASP.NET restarts application domains. Specifically, he was looking for the exact cause of what was triggering them on his application in a production shared hosted environment (was it a web.config file change, a global.asax change, an app_code directory change, a directory delete change, max-num-compilations reached quota,... |

Some may not agree but there are some ways that JavaScript and ASP.NET just click. If done correctly these two languages work extremely well together. One way that I have found that works extremely well for me is a login verification system using some JavaScript on the client and ASP.NET as the connection into our database to verify the information entered. Below is the script and explanation of how these two languages can sometimes work well hand in hand.... |

This is a simple demonstration of managing user account information on a server using ASP.NET. I decided that this might be a good way to get my feet wet in the whole ASP.NET environment, and the trials that I went through to get this far, might be of interest (and amusement!) to everyone else.
I am very much indebted to the numerous people on CP, who have helped answer some of my very basic questions. You all know who you are, and I thank you very much for your help.... |

I´m thrilled by how the Model-View-Presenter Pattern (MVP) is helping me on the "Get-Filters on Wizard, Show-Result" type of report I´m doing on work right now. So after grasping a little bit more of how MVP works, and believe me, it can get quite tricky, I decided to write about it.
I´ll illustrate the MVP pattern through a really simple sample, but one that could be used in lots of applications: A login UI. I´ll build the UI in the following steps:
-The Unit test for the UI (Yeah you rea... |

Under Windows 2000 (or NT) the Event Log is about the most important source of information for the administrator because all events that occurred are logged there - from success to catastrophical failure. And as it is so important, what would be more obvious than to make it accessible via the web?
The Event Viewer should be familiar to nearly everyone (see picture). In this article I will demonstrate how the list of entries can be emulated very elegantly using ASP.NET and the .NET Framework S... |

In this article I will be introducing a new way to catch Page-Level exceptions by introducing the HandleError Method. I will demonstrate what the firing order of the two are (try..catch..finally and Hand... |

Log4Net is a great logging library that is multi-platform (Java, PHP, C++, plSQL, etc). It has many conveniences but the ones that caught my attention are:
* The ability to change the logging destination with a configuration change at runtime, and for multiple logging destinations.
* The well behaved fact that errors in the logging library/configuration never bubble to the application.
* The extensibility by design of Log4net.... |

I will use the database named "Wintergreen," which we created in the first part of this series. Towards the end of this article, you will also learn how to apply Web Services for performing database operations. Typically, a site validates its users with their username and password. Some sites require you to feed in an e-mail address, which you gave at the time of registration.... |
