javascript - ActiveX "Class doesn't support Automation" -

this first effort @ activex command (and experience, last). high level, when seek utilize method console error reads "class doesn't back upwards automation".

i created custom activex control, installed via msi, , attempting utilize in mvc application. interface defined as:

[comvisible(true)] [interfacetype(cominterfacetype.interfaceisdual)] [guid("7ec603c3-3fb9-4e8b-a5b8-4d5804511e15")] public interface iprinter

the concrete class:

[comvisible(true)] [classinterface(classinterfacetype.none)] [guid("1f668100-532a-4077-bede-1610af2cc6df")] [progid("axcontrols.printer")] [comdefaultinterface(typeof(iprinter))] public class printer: iprinter, iobjectsafety

iobjectsafety interface , implementation:

[comimport] [guid("34abf5fa-1991-4d53-81bf-7dc7e3efd8f6")] [interfacetype(cominterfacetype.interfaceisiunknown)] public interface iobjectsafety { [preservesig] int getinterfacesafetyoptions(ref guid riid, out int pdwsupportedoptions, out int pdwenabledoptions); [preservesig] int setinterfacesafetyoptions(ref guid riid, int dwoptionsetmask, int dwenabledoptions); } public int getinterfacesafetyoptions(ref guid riid, out int pdwsupportedoptions, out int pdwenabledoptions) { const objectsafetyoptions options = objectsafetyoptions.interfacesafe_for_untrusted_caller | objectsafetyoptions.interfacesafe_for_untrusted_data; pdwsupportedoptions = (int)options; pdwenabledoptions = (int)options; homecoming 0; } public int setinterfacesafetyoptions(ref guid riid, int dwoptionsetmask, int dwenabledoptions) { homecoming 0; } [flags] public enum objectsafetyoptions { interfacesafe_for_untrusted_caller = 0x00000001, interfacesafe_for_untrusted_data = 0x00000002, interface_uses_dispex = 0x00000004, interface_uses_security_manager = 0x00000008 };

and javascript:

var ax = new activexobject("axcontrols.printer"); ax.print(json.parse(data.obj), "nameofprinter");

the error occurs on sec js line. i'm using ie 11. stepping through code appears command loads properly. if alter arguments invalid, different message leads me believe right , not issue.

any help much appreciated.
