1.) System Speaker - how to make sound with it

2.) Midi Files - The file format (I can play them, want to make them)

3.) Plug – Ins - How to make a browser plug in

4.) possibly istream - How to use istream and ostream like they do when they make ifstream and ofstream.(For makking another stream thing) - (not as urgent as other Q's)


Thanks SPH :)

P.S. QUIKLY HURRY HURYY! :) :eek:

Sorry i was on the toilet at the time.........

1) in windows pass. In dos its done with an interrupt call
2)go to here for file format info.
3)pass but msdn is bound to have info on this.
4)you could inherit istream in a new class.Depends really on exactly what you want to do.
