.Net - Bricscad: Entity identifier with persistence

Alberto Herrero

 Hi all! 
Using .Net Api:

I am devoloping a Bricscad Plug-in prototype for my company where:

-A operator selects a element through Bricscad

-A unique identifier of this element should be saved on a external database 

-A user will be directed from other apps (Documentum, .pdf, .Net clients, ...) to Bricscad, to a plane opened with Bricscad and to the correct element the operator previously selected

My question is:

Witch identifier should I use with persistence across Bricscad sessions? I have tried with ObjectId, BlockTableRecord... and other and they seem to change across BricsCad sessions. Only Handle seems to haver persistence, can I use that data?

Anyone could help me with info/links/... about those Id and their behaviour?

Cheers,

Albert

For anyone with this issue look at:

http://through-the-interface.typepad.com/through_the_interface/2007/02/getting_access_.html

From the comments on that WebPage:

"ObjectIds are per session, but get remapped on DWG load from the values stored in the file.

Handles are persistent across sessions."

And btw, to retrieve a objectId by its handle call to GetObject(false,"your handle from hex to long",0)
