Hi, As far as i Know the ActiveX control that you have bought from your customer is a liscensed ActiveX control, means that you can't use this control in your applications. Only those persons who have .lic file of this control can use the control in their applications. since you might not have .lic file so you can only see this control in your customer's built application and you can't built an application, making use of the control. I guess this answers you Muhammad Azam
