Make a existing control as an activex control

Question

I have made a biometric control in windows application(VS 2010, framework 4.0) which includes many complex type properties, methods and events. This control starts and stops the scanners and return results with images & templates. Also this control is using three dependency library (Class Library) which are not com component.

Now i want to convert biometric control as "ActiveX Control". I have taken references from many examples to convert a dll to com component but how can i handle the events.
can i have to convert dependency library as com component also or all references.
