ActiveX, Safe 4 scripting & initialisation

Hi everybody, I want to put this control up onto a webpage, and I want to make sure it is safe for scripting and initialisation and then eventually get it certified. This will be my first time to do this...It is a control were a person can record their voice using a mic..
Can anybody who has gone through this process have a look and tell me,

1. Is this control safe for scripting and initialisation?
2. If not, how can I make it as safe as possible for a user to use?

thanks
