I am using one activex control to draw charts using ASP(not ASP.net) But I am getting the same message box "windows has blocked this software because it can't verify the publisher" . So I modified the Internet options-Security level- Enable Unassigned ACtive x Control. This is really a problem to everybody whomever this site is accessing. So I want to a user friendly chart which will not make any problem to the client user. Please provide ASP API/Tool to resolve the above mentioned issue. Waiting for your favourable feedback
