Looking 4 different ways 2 develop mobile & desktop application on same code

[RABHARDWAJ]

We are planning to develop an application that is targeted for mobile and desktop platforms.
Can I use the same code base to develop application that are targeted for mobile and desktop platforms.
If I can't, how much of it can I re use to develop desktop and mobile apps with easy way?.

Or, how i can achieve it by adding it within a single running application with some kind of logic with differet views.

Is there could be some other RIA framework that can help with desktop and mobile application to achieve my goal, then please suggest that alternate also.
Would appreciate if anyone can share their experiences for doing similar efforts.

Loaded question. The answer is a mix of yes and no.

If you are talking using Ext JS and Sencha Touch then some things could be reused but the views will have to be different per as the UI for desktop is 99.9% of the time going to be completely different.

If you are going to use Ext JS but have different styles for mobile, that's pretty doable.
