Insert any binary file in C# assembly and extract it at runtime

by rahul 4/3/2010 1:03:40 PM

Problem> There is a binary file (I’ll use an Excel file) that you want to embed in any C# assembly. Later on, at runtime, you want to extract the file from the EXE and continue working on it. In this post, I will share the code and describe how you can do that. You can use the same technique for any other kind of binary file as well. Solution> First up, the reason why you may choose to embed a resource directly into your EXE is to ensure that no one tampers your file on which your code is... [More]

Timepass... Fix the code...

by rahul 1/27/2009 12:22:07 PM

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 2:07:00 PM

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 6 (Asynchronous Callback - Way 3)

By now, I have shown the following usages of delegates... 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() In this part, we will take a look at how you could use polling to figure out if the Asynchronous call is complete. So,... [More]

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

by rahul 1/22/2009 11:40:21 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 11:37:32 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 8:09:14 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]

A C# Argument Parser for a Windows Console Application

by praveen 1/11/2009 4:13:56 PM

There are a multitude of Argument Parsers available online. So why am I writing my own? Well to be frank… I did a search and couldn’t find anything that would be either “easy” to implement. I know that this is not much, but hope other programmers might find this useful if they are as lazy as I am and looking for a quick solution :-) I was actually looking for a parser which would return something like a Hashtable which i can loop through and load the values into properties of some sort. So here... [More]

How To Configure and Use the Logging Application Block

by praveen 1/5/2009 8:58:05 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]

Explaining Delegates in C# - Part 2 (Events)

by rahul 12/17/2008 10:51:39 AM

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]
