ActiveX control property exchange

[DanAmos]

I've written an ActiveX control in ATL and wish to set its properties from Internet Explorer. I can already do this using javascript as follows:

document.controlname.property=value;

I want to do it without Javascript in the object declaration:

<object ....>
<PARAM NAME=&quot;property&quot; VALUE=&quot;value&quot;>
</object>

I can get it to work with controls created using MFC - the DoPropertyExchange method seems to look after this. Unfortunately I can't get it working in ATL, and ATL doesn't seem to support DoPropertyExchange.

Does anyone know how to do it in ATL?

Thanks
Dan
