Hi

I have added some Ajax technology to my site. The left bar is having quite a few panels so I decided to make those panel Collapsible. Having worked with ATLAS before I knew how easy it would be to do this work.

All I had to do was add the CollapsiblePanelExtender to these panels. This extender targets any ASP.NET Panel control. The panel is also post-back aware so in case of post back the panel remembers it state

One of the most important things needed to track and improve Application performance is Statistics. Statistics related to database work is of great importance to the developers. Since they need to track how many times the application is calling the database and how much time each query is taking and which query can be improved to increase the performance of the Application. We can use the sqlConnection object to retrieve the statistics related to database work.

One of the new cool features of ASP.Net 2.0 is the Health Monitoring system. This is a very basic requirement for any Application. This provider has a comprehensive set of configuration attributes that you can use to customize the way it works.

ASP.NET version 2.0 health monitoring supports many standard events that you can use to monitor the health of your application. Examples of security related events that are automatically generated include logon failures and successes when using the ASP.NET membership system, attempts to tamper with or reuse forms authentication tickets, and infrastructure events such as disk access failures. You can also tap the event related to application start and Application end.

When we are logging the website we also want to log the user IP address.

The below given code gives you the IP address of the User Accessing the site.

HttpContext.Current.Request.UserHostAddress;
or
HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

To get the IP address of the machine and not the proxy use the following code

HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

Hi

Now the users can change the look and feel of the site as per their choice in my site. You can change the radio button on the left and accordingly the full theme (images, skin, and css) will change. This can be done very easily in asp.net 2.0.

After my friend (Thanks to Farghana) created a new theme for the site it required less than 10 line of code to change the theme on the fly.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Mail;

File upload has some big problem in asp.net 2.0 If you try to upload some file of more than 4 mb you will get and error. This is the default file size limit of dot net. This is defined in Machine.config. You can overwrite this in web.config. Like this

<System.Web>
<httpRuntime maxRequestLength="10000" />
</System.Web>

Have you tried to delete a directory programmatically in ASP.Net 2.0? Don’t try it; it can cause great problems to your site especially if you are using in-proc session. You will lose the entire session variable after deleting the directory and there is no way of getting those session variable back. This system is a change from asp.net 1.X.

I came to know about this the hard way. I was working on a project were project submission was a process of 6 pages (All in one page using the MultiView control). In the last stem I was supposed to delete the entire directory which was created during the process. Strangely I was loosing all the session values when the directories were deleted.
