How to run a command automatically when AutoCAD is launched

Hi, I'm trying to do a layer check before the user save the dwg file. If there is any layer not int the standard layer list, then the save operation is cancelled and a message box popped with the message saying "Non standard layer exists, please delete it before save the file!". Basically, I've achieved the target with register a DocumentLockModeChangedEventHandler as followings:

 public class BeforeSave
    {
        static List<string> LayerNameList = new List<string>()
        {
            "0","DOOR_FIRE", "DOOR_FIRE_TEXT", "WALL", "COLUMN","WALL_MASO","WALL-MOVE","DOTE","_Defpoints","_TK","_TQ","_Xref"};

        [CommandMethod("check")]
        public void LayerCheck()
        {
            AcadApp.DocumentManager.DocumentLockModeChanged += new DocumentLockModeChangedEventHandler(callBack_DocumentLockModeChanged);
        }

        private static void callBack_DocumentLockModeChanged(object sender, DocumentLockModeChangedEventArgs e)
        {
            if (e.GlobalCommandName == "QSAVE" || e.GlobalCommandName == "SAVEAS" || e.GlobalCommandName == "#QSAVE" || e.GlobalCommandName == "#SAVEAS")
            {
                Document acDoc = AcadApp.DocumentManager.MdiActiveDocument;
                Database acCurDb = acDoc.Database;

                using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
                {
                    LayerTable acLayerTbl = acTrans.GetObject(acCurDb.LayerTableId, OpenMode.ForRead) as LayerTable;
                    string a = string.Empty;
                    foreach (ObjectId acObjId in acLayerTbl)
                    {
                        LayerTableRecord acLyrTblRec = acTrans.GetObject(acObjId, OpenMode.ForRead) as LayerTableRecord;

                        string currentLayerName = acLyrTblRec.Name;

                        if (!LayerNameList.Contains(currentLayerName))
                        {
                            AcadApp.ShowAlertDialog( $"\"{currentLayerName}\" is not standard layer, please delete it before save the file!");
                            e.Veto();
                            return;
                        }
                    }

                }
            }
        }
    }

The script works fine. But the problem is that I should input "check" as a command so that the event works. I'm wondering if there is a way to execute the "check" command automatically when CAD is launched or the first drawing is opened or created.

Thanks a lot!

Hi,

see if you can load the dll through bundle mechanism, then you can make use of StartupCommand attribute as explained in blog https://adndevblog.typepad.com/autocad/2012/04/autoloader-the-startupcommand-parameter.html
