In my previous post, I spoke about a few very basic and simple reasons of using delegates - primarily callback. In this post, I'll talk about creating Events using delegates. I have tried to annotate the class with comments so that it is easy to comprehend. But IMHO, the best way to figure out what's going on is to copy/paste the following code and create breakpoint in the Main() class and hit F11 to step into the code. You will notice that Events are based on the Observer or Publish/Subscribe d... [More]

I hear a lot of confusion around Delegates in C#, and today I am going to give it shot of explaining the stuff with easy to understand examples. First things first... I will consciously try NOT to use any technical jargon to explain this concept. So here we go, without giving any technical explanation, let's start with a console application...// Declaration public delegate void VerySimpleDelegate(); class TestDelegate { public static void Foo() { Console.WriteLine("Foo wa...

Well... first of all, open ILDASM and drag/drop your EXE.   The application is called Attributes, and contains an annotated class, some annotated methods and fields. Notice the .custom instance void Attributes.xxxxxxxxx highlighted above. This tells you that the class is annotated. Now, how would you tell if Bar, Foo, and FooBar methods or AttributedVar, NonAttributedVar are annotated or not?

It all started last evening when I turned on my PC. I used to have a lot of partitions (Total 9) in my 2 160 GB HDD. Today when I started my PC, it showed me only 6 drives. The other HDD was present and Windows could recognize the HARD DISK. The problem was that although the Disk Management utility was showing the DISK 1 below as OFFLINE. The screenshot above shows when everything was working fine. When I saw the DISK 1 offline, I tried to bring it online but it threw an error message. I chec... [More]

In SharePoint, when you run the Post Setup configuration tool, you might have noticed that it works differently for Single server scenario vs. Farm scenario. How does the PSConfigUI decide the steps that needs to be taken? The answer is pretty simple, Registry Keys. The PSConfigUI reads the following keys in order to determine the correct mode in which it should run. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\WSS SETUPTYPE = {CLEAN_INSTALL | REPAIR | V2V_INPLAC... [More]
