Problem with directory burning

Hello Members,

I am facing some problem while using Nero SDK 1.05 version with VC++.
I am taking reference from Nero Sample example “NeroFiddles”. But this example is writing one file at a time.
I want to write one Directory which is containing two or more files.
I have made NERO_ISO_ITEM of my Directory. I don’t know this part is right one or not. but when I am Burning the CD it is giving me message like
“Burning Aborted by user”. I am not knowing where i look for this.
Can any body face like this problem prev. or guess where exactly the mistake?
Can anybody help me out?

reply me asap.
Thanking you in advance.
