How can I determine CD Serial Number before I burnt it

[qawsed]

yes, that's works, I tested. But, that CD is not be copy-protected.
I'm using 2 different mode for copy-protect.
and only CDRWIN allows to use 2 mode in the multisession CD.
in other burners(EasyCDCreator,Nero etc.) don't allow that.
after I use CDCreator, WINCDR didn't allow to add new data in changed mode to CD.

Do you know an other good way for protected CD?
May be I change method. Because I'm new in protected CD.
I'm always writing programs in Visual Basic.

thanks your help.
