If you could buy that exact program today (which you can't), it'd cost about $100?

The source code to a $100 program usually costs anywhere from 1000-10000 man hours! (How much do you make in 1000 hours -or- 6 months salary ?)

Would you give it to me for free? This is a forum, where people come for help, and help others.

As far as your post...

Creating a music player is easy. Controlling it is easy. Use Windows Media Player, and get the SDK from Microsoft.

Doing Flash is totally different. WMP doesn't do Flash, so you'd have to invent something. Then, nobody execpt Adobe knows how to do Flash, and they don't give it away (afik)

Probably over the head of any person on this forum...
