Getting "Note" field from extended data in Automap 2006

swagues — Tue, 12 Mar 2013 20:57:47 GMT

I've been trying to get the contents of the "notes" extended data property using autocad.net (C#), but I've run into a dead end. I've got the following code to get the DBObject:

DBDictionary extensionDictionary = transaction.GetObject(dbObject.ExtensionDictionary, OpenMode.ForRead) as DBDictionary;

DBObject note = transaction.GetObject(extensionDictionary.GetAt("AEC_TEXT_NOTE"), OpenMode.ForRead);

It's returning a non-null object, but I can't figure out what to cast it to so that I can get data out of it. I've looked online, and keep seeing Autodesk.Aec.DatabaseServices.TextNote referenced, but that's only for Autocad 2007 and later. Is there any way to access that data in Automap 2006?

Hi,

>> [...] extended data property [...]

Not sure if you mix something up, but "Extended-Entity-Data" (or EED) is not the same as "ExtensionDictionary".

To access EED's you can open a DBObject (at least for read) and there you find a property named "XData" (of type DatabaseServices.ResultBuffer).

No, the XData for the object being returned is null.

I've checked both the XData and the extension dictionaries for an entity that has something in the notes field and one that doesn't, and in the one that does I'm getting an entry in the extension dictionary under "AEC_TEXT_NOTE".

Hi,

can you then upload a drawing with one object having this data attached?

The purple square has a note (viewable under Properties->Extended Data).

Hi,

maybe I don't understand the question correct, but for me it's an DBDictionary not having to much info.

What the structure for this codes 280 and 281 means ... sorry I don't know that, I guess that is something architectural-specific.

If you want to get more info about this structure >>>this search<<< may help.

I can get the extension dictionary just fine- it's when I get the object contained in it using the "AEC_TEXT_NOTE" key that I wind up with a DBObject I can't do anything with.

I've done that exact search, but it just turns up references to Autodesk.Aec.DatabaseServices.TextNote, which isn't exposed in Automap 2006.

It is not in the API of AutoCAD Map3D any newer version too, so maybe you should post the question in the forum for AutoCAD & dotNET >>>here<<<.

Sorry that I'm no help now, - alfred -
