Hi
I am developing a C#.Net windows application for my project.
In that project I have an IDE to work on. The application is similar to
Adobe Photoshop.

My requirement is as follows.
1) I must be able to save my work in a file with custom file extention
(similar to *.PSD in photoshop)
2) After I save my work, if I double click on that file, my work should be
opened with my application automatically and I need to be able to work on
that as usual.
(similar to *.psd file, if we open that file, the file will be opened in
photoshop automatically)

How to do this functionality programatically?
(when we double click the file, my application has to be opened and file
must be opened in that application.)
Please help me out from this situation and guide me in right direction ASAP.

Thanks in advance
