#1 Burning Software

I've been looking through the DiskAtOnceFromFile example and I have several questions. This may just be showing my ignorance but I need to ask them anyway.

Why do you do a SetSpeeds then a GetSpeeds?
Why do you do a GetTrackInformation before you write?
Why do you do a GetDiskInformation before you write?
What does the SetCDTextItem do?
How do I set the gap between tracks for an audioCD?

I'm not really following what you are doing with the long integers. It looks like the values are being passed through the callback. Where does the quadpart come into play? I can't seem to find a structure or anything with that attribute. Is that something native to C++ or something?

How do I translate that in VB? Can I use a double or something?

Hi,



To know the current speed.



To get information about free space on the disc



To know the status of the last session and the status of the disc.
Disc can be closed.



It sets CD-TEXT for audio CD. But, CD-TEXT supported only for
Disc-At-Once raw P-W mode. For other modes it will be ignored.
ps. CD-TEXT - it's a text information about audio tracks. It can be recognized by some players and grabbers. For example, by CDEx.



Anton will answer you.



LARGE_INTEGER - it's a 64-bits integer type.
quadpart - it's a 64-bits part of LARGE_INTEGER
lowpart - it's a low 32-bits of LARGE_INTEGER
hipart - it's a high 32 bits of LARGE_INTEGER

Bye.

So you use GetSpeeds to get the drive speed before writing but I didn't see where you did anything with the information. What do you do with it?

You didn't answer the the question about using large integer with VB.

In the disk layout entry structure you have TrackStartingLBA and TrackSizeinLB. How do I calculate those?

We are just informing the user about current / maximum speeds.



Please, define the following type:


And then convert Lasrge_Integer to Double:




You don't need them to initialize or calculate. Just copy only file name and that's all. See our samples. We don't initialize them at all.

Thank you for the information. I was thinking along those lines myself. At least I was on the right track.

BTW, are you writing commercial application or coding just for fun?

I'm currently writing a program for my church. One of the steps in the process is to burn an audio CD.

If the program works well at my church, I may market it to other churches but we'll have to wait and see about that.

I still need the question on the audio track gap answered.

We have looked at our current API of StarBurn SDK and discovered that there is no way to control the gap for audio track for SessionAtOnce mode.

We will provide such function in the one of the next builds of StarBurn.

Is there another way to burn a gapless audio disk? Can I do it whith TAO or DAO?

What kind of timeframe are you looking at for the update?

Hi,



Gapless audiodisk can be burned only in SAO or DAO mode. (not TAO).
But current version of StarBurn does not provide such interface for the users.



We are planning next release of StarBurn SDK in october.

Bye.

I'm assuming then that gapless audio tracks will be supported when you have the new release in October?

Yes, you are right.
