ActiveX doesn't work with Visual Studio

Question

Hi I have created an ActiveX control in C#.net and using it in a html page.

HTML Code is :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
</head>
<body>
<OBJECT id="DemoActiveX" classid="clsid:14CBF038-4D43-457e-A5D2-CBED641218C5" codebase="DemoCSharpActiveXNew.cab">
</OBJECT>
<script type="text/javascript">
            var obj = document.DemoActiveX;
            alert(obj.AddToIEList());

</script>
</body>
</html>

When I run this html page from file system (e:\testpage.html) it installs the dll packaged in "DemoCSharpActiveXNew.cab" and calls the

obj.AddToIEList();

method , but when I run it from Visual Studio it installs the dll (packaged in "DemoCSharpActiveXNew.cab") but throws a java script error saying that:

Object doesn't support property or method

Why is this happening ? Any idea ?

Update: Now I updated the .inf file as per link given by @wakqasahmed, it goes like this:

When I run the web page with in local host it installs the activex control but same error

Object doesn't support property or method

is coming even after activex has been installed.

which browser version are you testing with? in both conditions. — wakqasahmed

It seems like your inf file is not correct.

opening file from file system is different from opening it through localhost
