Dealing with objects in LOCKED layer

[Anonymous]

Hi

I am trying to assign objects (only in UNLOCKED layers) with a new layer.

So basically, the user will select all the objects in the drawing.

After selecting (ex. press enter after window selecting), only objects in UNLOCKED layers will have a new layer.

Following is the code I am using...

But I keep getting eOnLockedLayer exception.

How should I handle this issue?

   using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())

            {

                PromptSelectionOptions pSelOpts = new PromptSelectionOptions();

                pSelOpts.MessageForAdding = "Select all objects";

                PromptSelectionResult pSelRes = acDoc.Editor.GetSelection(pSelOpts);

                if (pSelRes.Status == PromptStatus.OK)

                {                    

                    SelectionSet acSSet = pSelRes.Value;

                    foreach (SelectedObject acSSObj in acSSet)

                    {

                        if (acSSObj != null)

                        {  

    // This line I am getting eOnLockedLayer exception

                            Entity acEnt = acTrans.GetObject(acSSObj.ObjectId, OpenMode.ForWrite) as Entity;

                            if (acEnt != null)

                            {

                                acEnt.Layer = "newLayer";

                                acEnt.ColorIndex = 20;                               

                            }

                        }

                    }

                }               

                acTrans.Commit();            

            }

Just stop them being selected

// Autodesk.AutoCAD.EditorInput.PromptSelectionOptions
public bool RejectObjectsOnLockedLayers

{ // < ..>

}

Hi,

...or check the full syntax for TransAction.GetObject:

Public Overridable Function GetObject(id As Autodesk.AutoCAD.DatabaseServices.ObjectId, mode As Autodesk.AutoCAD.DatabaseServices.OpenMode, openErased As Boolean, forceOpenOnLockedLayer As Boolean) As Autodesk.AutoCAD.DatabaseServices.DBObject
     Member von Autodesk.AutoCAD.DatabaseServices.Transaction

ForceOpenOnLockedLayer Parameter, 

That sure helped me. Thanks!
