CAn u choose a way to do this?

I have some(not actually few) html files that contain forms.I have a task to accomplish in this.

The task is, i get a string (typed by user while filling the form) and need to do a database lookup (through ODBC) and apply some algorithm(right now it is a dll written in VC++) to convert the data to the required form. The data typed by the user should go through this stage before getting submitted to the server.

What I want now is, I am struggling to find the correct way of doing it. Can it be an ActiveX control in VC? Then I need to sign it before using. Can I create a ATL HTML Control? But can other part of html call the function of this control (as like ActiveX)? I need to learn more abt that 'window.external', i suppose. And what else can I do?


Thanx in advance,
Mahesh
