namespace Demo1
{
    public class Class1
    {

        [CommandMethod("AddAppEvent")]
        public void AddAppEvent()
        {

        }

        [CommandMethod("RemoveAppEvent")]
        public void RemoveAppEvent()
        {
            Application.SystemVariableChanged -= new Autodesk.AutoCAD.ApplicationServices.SystemVariableChangedEventHandler(appSysVarChanged);
            Application.BeginDoubleClick -= new BeginDoubleClickEventHandler(beginDoubleClick);
        }

        public void appSysVarChanged(object senderObj,Autodesk.AutoCAD.ApplicationServices.SystemVariableChangedEventArgs sysVarChEvtArgs)
        {
            object oVal = Application.GetSystemVariable(sysVarChEvtArgs.Name);
            // Display a message box with the system variable name and the new value
            Application.ShowAlertDialog(sysVarChEvtArgs.Name + " was changed." + "\nNew value: " + oVal.ToString());
        }

        static void beginDoubleClick(object sender, BeginDoubleClickEventArgs e)
        {
            Document acDoc = Application.DocumentManager.MdiActiveDocument;

        }

        void currentDoc_CommandWillStart(object sender, CommandEventArgs e)
        {
            //Application.ShowAlertDialog(e.GlobalCommandName);
            Document acDoc = Application.DocumentManager.MdiActiveDocument;

            Application.ShowAlertDialog(strDWGName);
        }


    }
