create com dll with c# and raise vb event

I need to create a dll with c# that is com visible so that I can use it in a web page  using the <object> tag.  This dll will also have to raise events in vbscript, so that the web page can get the event (the web page is old asp).  

I can write the dll, but how do I get it to raise a vbscript event?

more specifically, if you look at the post by kossovsky, you'll see a good example on how to build the DLL, register it, then call it from an asp page:

Set Base64 = CreateObject("ComComponent.Base64")
Result = Base64.Encode("some string to encode")

yes, but it doesn't show how to raise an event.  I need to be able to respond to events from my web page with a vbscript function.

I guess I should rephrase my response:  I need the web page, via vbscript, to respond to events raised from my com object.  Hope that makes more sense.

Web pages doesn't work that way. All events come from the browser. If there is no request to the server to return a page, there is no code running in your web application.

What specifically is it that you are trying to accomplish that you though creating events from the server side would solve?

I'm going to repeat GreenGhost's comment another way with some differences.

A web server can run events in many web server languages as can a copy of a page with JavaScript in the browser.  However, the server events only fire when the browser requests the page.

Remember, a web browser requests a web page using the URL in the address window.  The web server receives the URL request and then fires server code and logic to then transmit the page back to the browser.  As the page is being rendered on the browser JavaScript can begin to execute as the page is loading based on how it is inserted in the page.  Once the full response has been sent to the browser from the server, they disconnect from each other.

The server cannot push events back to the browser.  The browser using JavaScript timers can poll the server without refreshing the entire page, however, the web server only responds to requests from the browser.
