#1 Burning Software

Hello,

I'm having some trouble getting the DiscAtOnceFromFile example to work in C# / .NET 2.0. It will burn an ISO image perfectly, however it doesn't work with audio.

I tried installing the HTTP://WWW.ROCKETDIVISION.COM/DOWNLOADS/WMFDIST.EXE, but the same thing happened.

I recompiled the C example in VS05 and it works for both ISO/audio. I'm thinking there's something wrong with a struct declaration or API call/declaration, specifically one of the following:

StarBurn_CdvdBurnerGrabber_DiscAtOnceRawPWFromFile
StarBurn_CdvdBurnerGrabber_DiscAtOncePQFromFile
DAO_DISC_LAYOUT
DAO_DISC_LAYOUT_ENTRY

But, I've been staring at those 4 declarations for two days now - maybe it's something else?

Hopefully one of you experts can help me out

C# project (works with ISO, not with audio): http://cdtag.com/daoff/DiscAtOnceFromFile_CS.zip
C project (works with ISO/audio): http://cdtag.com/daoff/DAO_C2.zip

C# log file (not working): http://cdtag.com/daoff/notworking_cs_example.zip
C log file (working): http://cdtag.com/daoff/working_c_example.zip

The log files start showing a difference around line 400.

Any help is appreciated. Thank you!!

Small update: I believe this has to do with how 'CHAR m__CHAR__TrackName[ MAX_PATH ];' is marshalled in DAO_DISC_LAYOUT_ENTRY. I noticed that if I passed a normal 'String' to StarBurn_IsAudioFileSupported it would come back EN_UNSUPPORTED_AUDIO, but when I changed the parameter type to a StringBuilder it worked! Unfortunately you cannot have a StringBuilder in a struct that goes to an API call. So, I'm thinking something along the lines of:

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public String TrackName;

but of course this didn't work, or I'd just post that it's resolved Maybe an IntPtr?

Any help is appreciated. Thank you!!

Hi!

This was a problem of COM appartments with .NET. We already fixed it, please drop a mail to [email protected], we'll send you the updated DLL before the official release.

Woops, my apologies. I misread your reply the first time. I changed the struct to match the definition in the new StarBurn.h (401 elements in FULL_TOC_ENTRY_RAW__Unsorted) and it works perfectly. Thank you!
