Create a C# class Library.

In a class file type the following:

public calculate()
{

}
public int add(int a, int b)
{
return a + b;
}

1) Open project properties and add a key file then tick the Regster for com interop option

) build the library.

2) Open the command prompt of ASP.NET.

3) type gacutil /i dllName

4) type regasm dllName

5) Then open the notepad

6) type the following:

<html>
<head>
<script type="text/javascript">
function fun()
{
var obj = new ActiveXObject("createActiveXcontrol.calculate");
//var obj = new ActiveXObject("createActiveXcontrol.dll");
alert(obj.add(6,5));
}
</script>
</head>
<body onload="javascript:fun()">
</body>
</html>
