Doubts about ActiveX

[davinia1]

Hi,
please, if anyone could give me any response.

1. How could I set <PARAM NAME=name_of_a_property VALUE... with ActiveX Control Pad?

2. I have to read a file .txt from a URL to save information in memory. Do I need sockets(winsock or WinInet?)?

3. ActiveX Control Pad adds <PARAM NAME="_Version" (and _ExtentX, _Extent_Y and StockProps). What is the meaning of that?

4. I can't download (or see) an ActiveX control from a server I've installed in my computer (although I can see it if I have it registered), why? I've seet the security level to low with Tools-Internet Options-Security.

Please, it's really important. About all number 2.
I would be very very .... very grateful :_(

Thanks in advance.
Davinia.
