about managing Extentions in C#

utkarshd

Hi everybody,

I am a .net newbie, I am currently working on my personal college project on c#. I have decided to make such a notepad, which will be something more than the old plain notepad. The user could change the colour, font size of the text; he could add images; he can email the document; and he could make graphs, wordart,etc. I want it to save documents typed in it with a separate Extention, and the user could be able to open the saved file by just clicking it in Windows Explorer. How could I do that?

please tell me how to do that.

Thank you,

Utkarsh
