If you are using COM objects like Microsoft Excel or Microsoft PowerPoint, you may sometime notice that the COM instances are not releasing from the process list; even though you called Close(), Quit() on the application instance.

 

In case you faced the same issue, this post will guide you to find the Process ID (from the HWND) of that particular instance to take further action to release it.

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.

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 has the capability of accessing the COM object using the COM API. You can access any program installed in your PC using those APIs in Silverlight. You can open Notepad, Word, Excel or Outlook from Silverlight application.

 

Here I will demonstrate you the step-by-step tutorial on opening an Microsoft Excel book followed by data sharing between the Silverlight application and the Excel Sheet. Here we will use a DataGrid which will load some customer information. Then we will pass the data to the Excel Sheet and then we will modify the data in the external application (i.e. inside the Excel sheet). You will see that, the modified data will reflect automatically to the Silverlight Application.
