问题
I'm a novice programmer and have developed a notepad replacement application for my own needs (with some more features). When I double click a .txt file (or a customizable extension such as .abc), I want the file to run in my application just like notepad. I read about File Association with programs but I didn't get much of it.
Can someone point me to how I would do this? Just give me a few ideas, I would really like to do this and have an option for my users to set the application as the default text editor. Help would be much appreciated.

If you are using click-once deployment (i.e. "publish" in VS for a windows exe), you can specify file associations there, and it will do everything for you. I can't guarantee that it'll take precedence over notepad, though. For that you might need a proper installer...
MSDN shows how

Have a look here: how to force that any file of a certain type will open with my program?
