Was looking through the exports for DBProBasic3DDebug.dll and came across two entries that looked interesting:

bool __cdecl DBOConvertBlockToObject(unsigned long,unsigned long,struct sObject * *)

and...

bool __cdecl DBOConvertObjectToBlock(struct sObject *,unsigned long *,unsigned long *)

Anyone have an idea what these do and how they might be used? I was hoping to find some DBO/Memblock functions that weren't documented. Didn't find anything obvious, could this be related though?

On a side, but slightly related note... does anyone know of a good reference for the DBO format that might be a bit easier for a .NET programmer to grasp than C++ header files?

Design documents?!? What design documents??? I thought we were just going to wing it!!!

Yes, it takes a DBO data block and converts it to an object - you pass a pointer to the data, the size of the data, and a pointer to a pointer to sObject, and it will put an object pointer there for the object it created.

The DBOConvertObjectToBlock does the reverse.

To be honest, they aren't really any use for DLL writers, as although you can create a new sObject, it isn't given an ID number or included in the rendering.

No.

No.[/quote]

Ok. That is too bad, but I guess I will just have to bite the bullet and try to understand this then. Maybe after I do I can make a good reference for .Net programmers then. I think that more of the knowledge should be put into references and tutorials than has been done so far.

Where can I get the lastest C++ headers for the DBO format? The last ones I saw were the 5.9 version and I believe it has changed since then.

As I work on trying to understand these I will probably be on here with lots of questions. Hopefully the wonderful minds here will be willing to lend me assistance. No sarcasm intended.

If you download and install the GDK, the files are available there - I have no idea whether the file have changed since 5.9 or not.
