Can i convert Desktop application to Windows application?

hi,

as Ramesh mentioned, you cannot convert directly Desktop app to web based, bcause in desk top app when we build, we will think platform as windows, so we will add so many dependend feature to it, like dlls, which will not support web app, so you can take only your business logic, data access layer, etc, which is commen, and you should design as web forms(ie, html support).
