File:Indian Rupee symbol.svgIn July 2010, Indian Cabinet selected a new Symbol for the Indian Rupee which looks like as the snapshot shown at the left side. In this post, I will describe you how to integrate the same symbol in Silverlight application.


As the Unicode is not present for that till now, hence we need to use some font to write the letter using that. Fordian Technologies has the font and you can download it from their official Blog. The latest version of the font is available here: Rupee Font Version 2.0.


Let us have a quick tutorial on it to create a Silverlight application with the new Rupee Symbol of India in it.

Before starting with the next part of the discussion, let me ask you some questions. Are you a Silverlight developer? If “Yes”, how many times you create a Silverlight Out-of-Browser application? For that, how many times you create an UI and write code to instruct the user to install the application as OOB application. I think the answer will be “Many Times”.

To solve this, we will create a Custom UI Wrapper (like the above snapshot) which will have all the codes necessary to guide the user. Once this is done, we don’t have to write the same installation code again and again over the applications. Read through the description and don’t forget to leave your comments and suggestions.

imageMicrosoft has released Silverlight for the Symbian OS, which will allow your Silverlight applications to run in some selected Nokia handsets. Earlier, Silverlight was only available for web on desktop for Windows, Mac operating system. Later Moonlight came out, which is the linux version of Silverlight. Then Microsoft released Silverlight for Windows Phone 7 and this is the time for Symbian platform targeting mobile devices such as Nokia N97, N97 Mini XpressMusic etc.

You all know that, Silverlight 4 has the feature to talk with COM APIs. In my earlier posts I already mentioned various Interoperability functionalities of Silverlight. You can see some articles in my Blog. In this article, I will show you how Silverlight can read your local files, folders and drives. At the end of this Article you will be able to open any file/folder/drive and read their attributes.

Here I will demonstrate by creating a small application like Windows Explorer and reading all your drives and their contents in the screen like below screenshot:

You will be able to open the drive and browse through it’s contents (subfolders and files). Interesting? So, read it out and learn Silverlight 4 a bit more. Don’t forget to leave your comments at the end.

imageHave you ever heard of Text to Speech engine? “Yes” I think. Yes, it is not a new thing in the Computer World. It was available since Windows 98 (as much as I can recall) but it is completely new in Silverlight. You can now use the Silverlight application to give an API call to the SAPI Engine which will convert the text to voice. Sounds Good? This is achievable using the COM APIs only.

 

Here I will describe you how to use COM API to give a TTS call to the SAPI Engine. After reading this topic here, you will be able to write your own code to develop your own application having the Text to Speech functionality in Silverlight 4.

Have you ever tried Trimming your Text in Silverlight 2 or Silverlight 3? If yes, just recall the lines of code you wrote for trimming your text content and showing an Ellipsis (i.e. “…” three dots) at the end of the text. If you didn’t try it earlier, then just imagine what you have to do and how you will do. Also imagine the no. of lines you have to write. Confused smile

In this post, I will show you how I can implement this feature the easy way. Stop!!! I will not write here a huge code nor I will use any library to do that. Microsoft has added this functionality in Silverlight 4. You just have to set the Enum value to the TextBlock property. Surprised smile Wao!!!

So, how to do that? Let us try it.

Recently I was interested to work with the Physics Helper for Silverlight. I saw couple of demos on net which uses the Physics library for Silverlight to create good animations with Friction logic. Yeah, friction. You can drop a ball on a surface which will bounce over that surface. I found it very interesting and thought to create a Simple Demo for it.

Here I will demonstrate you creating a Sample Application using Expression Blend. You don’t have to write a Single line of Code using Visual Studio. Surprised smile Is it? Yes, lets start doing that.

Microsoft released Windows 7 last year which has lots of functionalities including a nice UI. Among those features one of the most user friendly feature is Pin/Unpin application to Taskbar. You can develop WPF or Windows Forms applications in which you can implement this feature. But do you know that this is also possible in Silverlight? Yes, Silverlight 4 has the power to talk with any other application using the COM API. You can read one of my earlier article [Silverlight 4: Interoperability with Excel using the COM Object].

Silverlight 4: Interoperability with Windows 7 Taskbar using COM

 

In this Article I will show you how we can talk with the Windows 7 Taskbar. Read the complete Article and provide your feedbacks or suggestions.

image Microsoft launched their Expression Studio 4 today (7 June 2010), as expected. It includes Sketch Flow, Expression Encoder, Expression Web and Expression Design. This release comes with the Upgrade version. If you already have the licensed copy of Expression Studio 3, it will auto update to Expression 4 and you need no new license.

You can download it from Microsoft Expression Studio site.

Please note that, if you are developing in Silverlight for Windows Phone 7 and want to use Expression Blend, don’t install this version of Expression Studio. Continue working with the Expression Blend 4 Beta and the Windows Phone 7 CTP Tools for developers. Once the Windows Phone SDK releases, there will be service pack for Expression Studio.

Sometimes we write the following code while working with EventHandler and that may create some problems. I will discuss this later on. Let us see the code:


                private void RaiseOperationComplete(EventArgs e)
                {
                    if(OperationComplete != null)
                    {
                        OperationComplete(this, e);
                    }
                }



In the above case, suppose two thread subscribed to the same OperationComplete handler and one unsubscribed the event. In such scenario the OperationComplete event will become null and for the next thread due to the event is null it will not execute. This happens mainly in multithreaded applications but you can't guarantee for single threaded application too.

So what to do? How can we make sure that our application will not come into such situation and work properly?
