DxfCode.ArbitraryHandle vs DxfCode.Handle

[kazfukuoka]

Hi Community,

For Xrecord, what is the difference between
DxfCode.ArbitraryHandle and DxfCode.Handle?

For storing a Handle, which type is right?

  var rb = new ResultBuffer(
    new TypedValue((int)DxfCode.ArbitraryHandle, id.Handle);
    new TypedValue((int)DxfCode.Handle, id.Handle);
  Xrecord xrec = new Xrecord();
  xrec.Data = rb;
  xdic.SetAt(APP, xrec);
  tr.AddNewlyCreatedDBObject(xrec, true);

Also for storing ObjectId, which type should I use?
DxfCode.HardPointerId or DxfCode.SoftPointerId?

I wouldn't recommend storing handles in Xrecords, but ArbitraryHandle is probably a handle that is never translated when the object containing the Xrecord is cloned (this is speculation as I've never seen docs that describe what it is exactly).

As far as what DxfCode you should use to store ObjectIds (which is the preferred way to store references to other objects), it depends on what objects are being referenced and the relationship they have with the object that owns the referencing Xrecord.

Feel free to elaborate.

Thank you for the explanation. 

There seems to be a lot of things I do not know about this topic.
Where can I study those things?

Probably not much has been written for .NET yet.
Need to dig into ObjectARX to find any info.

AcDbSoftPointerId

Sorry, I tried to reply to your previous post but I couldn't because of a problem with this discussion group software. Yes, the native ObjectARX docs are the most complete source of information on this.
