Call javascript where and what? You loaded DLL using object tag, now what is the link of javascript on click button to this DLL object?

function doSomething() {alert("doSomething called"); }

above is the javascript funtion which i want to call through a button which resides on the UserControl (DLL) embedded on IE

There is no need for a custom control, just use [button].OnClientClick.

the link which is provided uses web controls which am not using.
in my case there is HTML page which has HTML object TAG used to
embed controls as DLL on browser.

Why would you use a windows forms control on a web page?
This doesn't make sense, It seems like you are trying to recreate the wheel if the only reason you have created this 'ActiveX' control (which for the record isn't really an ActiveX control is to call JavaScript when the button is clicked, so to reinterate; use Windows controls in Windows apps and use Web controls for Web apps unless there is a very very good reason to not.

I can achieve my task through ActiveX controls which can call Javascript function but they are built on VB6. I wanted to achive my task using C# (.NET 2.0). If i use web controls as u said then i must have aspx page to render that controls. I have an HTML page which renders a DLL using an OBJECT tag.
