Run an ActiveX through Web

We have a webpage that works fine on the local computer as it uses a COM Object that is only available in the local computer.

the program generates HTML code:

<html>
  <head>
     <script type="text/javascript">
     <!--
       function ResizeControl(){Y = document.body.clientHeight;if (Y < 1) {Y = 1}X = document.body.clientWidth;if (X < 1) {X = 1}ActiveX.width = X;ActiveX.height = Y}
     -->
     </script>
     <style type="text/css">html, body { overflow:hidden; } </style>
  </head>
  <body OnResize="ResizeControl()" OnLoad="ResizeControl()" leftmargin="0" topmargin="0" rightmargin="0" bottommargin="0">
     <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14">
         <PARAM NAME="tabName" VALUE="Complaints">
     </object>
  </body>
</html>

and shows fine

My question is, How can we port this into a web environment? As the Delphi developer has no idea and I'm not a Delphi fellow.

I want to be able to use this "webpage" on a web address

http://INTRANET/mysite/thispage.html

Any idea, any though, any door to open is greatly appreciate :)

You should deploy the ActiveX control on your web server and provide the URL to the .cab file in the HTML page in the codebase attribute of the object element so users can download and install the ActiveX component through a standard dialog in Internet Explorer.

I see two options:

  1. Write ISAPI dll that internally calls COM object and returns the result. Use Apache for ISAPI host.
  2. Write standalone simple HTTP server. With Indy it can be done like a breeze. Do the same as with ISAPI. Just call COM and return the HTML.

This also ensures security because COM is not directly exposed to the internet. It is only accessible through the proxy.
