How to deal with this type of flash warning

[MengQingKuan]

I develop a ocx for playing flash on web .Then I also place a swf that has encrypted on web,before it can be played it must retrive the need information form ocx for decoding.But when I play the swf on web,it will warning that Adobe Flash Player has disable this type of unsafe operation.So I can't play the swf normaly , I wonder if I should apply a digital signature from Adobe for my ocx if I intend to use my ocx on web.

A digital signature will not solve your problem. A networked SWF -cannot- access a local file system SWF. So the security sandbox error you're getting is legitimate.

Please read the Flash Player security articles on the Adobe Developer Connection:
