LinkPath property of the Ole2Frame class: throws an Exception.

[Anonymous]

Hi!

I'm writing an application that scans in dwg files if there is any OLE object like xls. I need to get the path of this file. To achieve it I use the LinkPath property of the Ole2Frame class, but this throws an Exception.

I post a part of my application code:

Transaction tr = doc.TransactionManager.StartTransaction();
using (tr)
{
BlockTableRecord btr = (BlockTableRecord)tr.GetObject(btrId,OpenMode.ForRead);
foreach (ObjectId entId in btr)
{
Entity ent = tr.GetObject(entId, OpenMode.ForRead) as Entity;
if (ent != null)
{
Ole2Frame ole = ent as Ole2Frame;
if (ole != null)
{
ed.WriteMessage(ole.LinkPath.ToString());
}
}
}
tr.Commit();
}
----

The Exception information are: address error: 0x79e832f3, thread 0x1570. Error code: 0xc0000005

Can someone help me??
Thanks!!

There's known bugs in the Ole2Frame.

In AutoCAD 2008, if you try to access one and the linked
object

or file is not present, it will terminate
AutoCAD.

IOW, the entire feature is unusable from
size=2>the API.
