ActiveX Help

Alright, I am just curious as to what IS ActiveX? I understand that it is used with windows, and is event-driven. How do they operate? What interface is provided for ActiveX controls? How do you get data from them? How do you send data to them? Are they easy to use? What aspects give them the advantage over common controls that come with MSVC? How do I add them to a MSVC project as I do with VBasic? ================== My (soon-to-be) Cherished Cookie of Appreciation: -- MattB - for WinSock advice --
