Get handle of Object in AutoCAD 2015 from vb.net

问题

I have managed to link my Visual Studio to my AutoCAD 2015, but I am struggling to get a handle on a text object within my AutoCAD project from vb.

I was wondering if anyone had any suggestions or tips as to how I could get a handle on an AutoCAD object from my vb code.

Ultimately I want to be able to change the text of this object from my vb code.

Any help or suggestions are appreciated..

Thank You in adavance

I would suggest you start with My First Plugin tutorial then this AutoCAD .NET Training material (full list of training material here) that is presented at this video.

Here is a quick example on how list all AutoCAD entities on Model Space:

[CommandMethod("listAllOnModelSpace")]
public static void CmdListAllEntitiesOnModelSpace()
{
  Database db = Application.DocumentManager.MdiActiveDocument.Database;
  using (Transaction trans = db.TransactionManager.StartTransaction())
  {
    BlockTableRecord mSpace = trans.GetObject(SymbolUtilityServices.GetBlockModelSpaceId(db), OpenMode.ForRead) as BlockTableRecord;
    foreach(ObjectId entityId in mSpace)
    {
      Entity entity = trans.GetObject(entityId, OpenMode.ForRead) as Entity;
    }
    trans.Commit();
  }
}

Just had this in C#, but you may translate to VB.NET here.
