Did you know: How IIS 6.0 handles Custom Errors when aspnet_isapi.dll is mapped as a wildcard extension?

by vivek 3/23/2010 12:21:34 AM

Sometime back I came across a very good question on ServerFault and I thought of doing some research to understand how IIS handles Custom Errors setting when all requests are passed through aspnet_isapi.dll. Here is a brief background: Scenario 1: We have a Wildcard mapping configured for aspnet_isapi.dll with “Verify that file exists” unchecked. We also have Custom Errors configured for 404. We have configured it as a URL and the path is /404/. Remember the path 404 does not exists in ww... [More]

Programming “gotcha” when you code for Vista and beyond!

If you blog, and haven’t used any of my plug-ins for Windows Live Writer, may be you should. In this post though, the agenda is not to push you to install the plug-ins but tell you about my experience with Application.StartupPath and how problematic it could be!!! Well, it all started when I decided to write a few plug-ins for my favorite Windows Live Writer. The SDK was easily available, and I found that any new plug-in was required to be installed in the Plug-in folder inside WLW Installation... [More]

LINQ Performance - Part 1 - LINQ to Collection

by rahul 1/27/2009 7:18:23 AM

There are multiple benchmarking results already out there for LINQ. The reason why I am doing this again is the because I have heard multiple times that the latest version of LINQ contains a lot of improvements. My current configuration is... Windows Server 2008 Enterprise SP 1Visual Studio 2008 SP14GB RAM System.Core version 3.5.30729.1 In this post, I will take a look at the results ONLY from LINQ to Collection (An array of strings). You can play around with the code and post other findings (... [More]

Timepass... Fix the code...

by rahul 1/27/2009 5:10:07 AM

Create a C# Console application, and paste the following code in the Main method... for (int i = 0; i < 5; i++) { //Generating a Random number between 0 and 100000 int intRandomElement; Random r = new Random(); intRandomElement = r.Next(1, 100000); Console.WriteLine(intRandomElement); } If you run this code in debug mode, you should be able to get the output as expected. But if y... [More]

Explaining Delegates in C# - Part 7 (Asynchronous Callback - Way 4)

by rahul 1/25/2009 6:55:00 AM

This is the final part of the series that started with... Callback and Multicast delegates Events One more Event Asynchronous Callback - Way 1 - BeginInvoke > EndInvoke Asynchronous Callback - Way 2 - BeginInvoke > AsyncWaitHandle.WaitOne(x) > EndInvoke > AsynWaitHandle.Close() Asynchronous Callback - Way 3 - BeginInvoke > Poll for result's IsCompleted > EndInvoke In this scenario, if we go with the husband-wife-kiddo analogy, I will need to introduce another guy! No no... [More]

Explaining Delegates in C# - Part 5 (Asynchronous Callback - Way 2)

by rahul 1/22/2009 4:28:21 AM

In this part of making asynchronous programming with delegates, we will talk about a different way, which is a little better than Way 1. In the previous post, it was like a husband telling his wife... You know honey, I have a lot of work to do. Why don't you help me up by doing something that you can do pretty well . In the meantime, I will take care of some other stuff. As soon as I am done, I promise I will pick you up. Notice that, although it looks like a good way of getting the work done, i... [More]

Explaining Delegates in C# - Part 4 (Asynchronous Callback - Way 1)

by rahul 1/22/2009 4:25:32 AM

So far, I have discussed about Callback, Multicast delegates, Events using delegates, and yet another example of events using delegates. In this post, I will take this topic one step forward and show you an example of Asynchronous callbacks using delegates. Let's say a client calls a method that takes 40 minutes to complete, how do we communicate with the client? Option 1> Keep showing that busy Cursor for 40 minutes!!! Option 2> Keep updating the clie... [More]

Explaining Delegates in C# - Part 3 (Events again)

by rahul 1/20/2009 12:57:14 PM

I was thinking that the previous post on Events and Delegates was quite self-explanatory. A couple of days ago, I received an email which said that may be it is not that good as to explain what I want to achieve in life through that event. So, I thought why not write another post on Delegates and Events to make things clearer from a practical (or may be not so practical, "BUT" just another simple and practical example. There is no harm in trying, after all...) Here is the requirement... You have... [More]

How To Configure and Use the Logging Application Block

by praveen 1/5/2009 1:46:05 AM

I recently downloaded the Enterprise Library 4.1 released in October 2008. I guess the enterprise library has done a lot of improvements from the 3.x version to the current 4.x that's available and not just making it work with .NET Framework 3.5 and integration with WCF. I downloaded the library and as all bad developers do, immediately started looking into the Quick Start code sample and trying to figure out, how to get it quickly integrated with my application. Whatever happened to doing rese... [More]
