Create an ActiveX dll in VB6, have one class which contains one public method which returns a temperature value. Inside that method cut/paste your vb code from your form, but modify it so the method returns a string instead of populating a form element. 2. Compile your dll, copy it to your webserver and register it (regsvr32.dll). 3. Create a simple asp page that creates your object, calls your getTemp method or whatever you want to call it, and does a response.write of whatever the method returns. 4. Once you are comfortable doing this, create a new method that changes alarm points. This method would be invoked thru a form on a web page. Hope this helps.
