what to implement for the "open with" option?

[Binayak]

Hi, I have written a SDI application which opens a XML document from the file->open menu and works on it. Now, I want to right click on any xml file and go to the option "open with" and select my SDI application from the list, and the application would show data from the xml file the way it works for the file->open menu. How can do that? Please advise.
