[URGENT] about ActiveX control

I write my ActiveX to run on WebBrowser.
I have several topics to ask everybody.

1. To pass PARAM from HTML to ActiveX is PARAM tag right? and when I want to read PARAM value use ReadPropoties() method right?
2. When I pass PARAM from HTML to ActiveX, I use PARAM tag in <OBJECT></OBJECT> It warns me "An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?" and then I clicked YES. Oh God. My ActiveX can't run and have no anything show in webbrowser. When I remove PARAM tag it can.
Can someone help me please?
Thank you.
