Hi

How to obtain the name of a block ?

<CommandMethod("LISTBLOCK")> _

Public Sub ListBlock()

    Dim ed As Editor =
AcApp.Application.DocumentManager.MdiActiveDocument.Editor

    Dim db As Database =
HostApplicationServices.WorkingDatabase

    Dim trans As Transaction =
db.TransactionManager.StartTransaction()

Try

    Dim bt As BlockTable
= CType(trans.GetObject(db.BlockTableId, OpenMode.ForRead),
BlockTable)

    Dim btr As
BlockTableRecord = CType(trans.GetObject(bt(btr.ModelSpace), OpenMode.ForRead),
BlockTableRecord)

    Dim id As
ObjectId

    For Each id In
btr

       
Dim ent As Entity = CType(trans.GetObject(id, OpenMode.ForRead, False),
Entity)

        If
TypeOf ent Is BlockReference Then

       
    '?????

       
End If

    Next

Catch ex As Exception

   
ed.WriteMessage("Error ListBlock")

Finally

   
trans.Dispose()

    End Try

End Sub

Here's how I do it in C#,

foreach(ObjectId objId in
btr)
{
    DBObject dbObj =
t.GetObject(objId,OpenMode.ForRead);
    BlockReference blkRef
= dbObj as BlockReference;
    if
(blkRef!=null)
   
{
        BlockTableRecord blkDef =
(BlockTableRecord)t.GetObject(blkRef.BlockTableRecord,OpenMode.ForRead);
       
CommandLinePrompts.Message("\nGot a block named " +
blkDef.Name);
    }
}
