.. still couldn't solve the problem.
to make the situation clearest.. i'm on form. i have a button here and when i press it i want to do thing i described above(executing a command/program, also being possible do execute piped/redirected commands).
my project(homework) is to make a nice interface(a frontend actually) for cdrecord and implement fuctions and interface like Nero Burning Rom. if you think that helping me to overcome executing something is doing my homework...
seems like my teacher will be glad to tell me that i will need to repeat this year for not passing at his subject
anyway. thank you for at least answering to my initial post and having patieence to read my text.
anyway.. seeems like i'm all on my own.
