Hello, I want to build a radio, where I can programe SPOT's(publicity) in certan parts of the day. For example I want to be able to programe a SPOT to pass on the radio: - one time in every X time for example(one spot passing every hour) - just passing one time a day in a exactly hour for example(pass at 8:30AM every day a morning SPOT saying good morning) Note: Every SPOT must also have a date in and date out, for example a SPOT can start to "exist and work" from 14/1/2016 until 5/2/2016. I think maybe is better to create a c# desktop aplication to manage the radio and SPOT's that will generate a XML with the info of all spot's and info of the radio(folder where are the music, folder where the SPOT's are, etc), and do a web app(it need to work's online and localhost) that reading that XML, will play the radio and the SPOT's configured.
