The C# ActiveX should support 'ScriptCallbackObject' to bind the event to a javascript function like below: var clock = new ActiveXObject('Clocks.clock')

He used the 'extension' in a complex way due to the example he chose but if you make it simple, attaching the handle directly to the event itself, it also works.

If you don't do that the javascript can't bind to the event handler. The above project link from our friend Mr. The only way to make it work is by 'Extending' the event's handler functionality: OK, but if you are using C# (.NET 2.0) with inherited UserControl (ActiveX). This has to be a custom ActiveX control for what we're doing. What is the proper way to handle an event being sent from an ActiveX control? Right now we're only interested in getting this working in IE. but it results in the Javascript error 'GetControl is undefined.' We've tried variations on the following: var GetControl = document.getElementById('M圜ontrol') Specifically, if we put this into a plain HTML page it works fine, but if we put it into an ASPX page wrapped by the tag, we get a 'M圜ontrol is undefined' error. However, when inside a layout in which the control is buried, the Javascript cannot find the control. Historically we've been able to use the following IE-only syntax to accomplish this on different projects: function M圜ontrol::ReceiveMessage(msg) I have a custom ActiveX control that is raising an event ('ReceiveMessage' with a 'msg' parameter) that needs to be handled by Javascript in the web browser. This is somewhat of a follow-up to an answer here.

How do i get activex to work
