when use .net usercontrol in vb6, .net usercontrol compiled com. expose events of usercontrol, need pack events exposed interface, applied interfacetypeattribute , apply interface control class. following sample. 

code snippet

[interfacetype(cominterfacetype.interfaceisidispatch)]

    public interface imycontrolcomevents

    {

        [dispid(0x60020000)]

        void myevent();

    }

 

[comsourceinterfaces(typeof(imycontrolcomevents))]

    public partial class mycontrol  : usercontrol

    {

         .........

     }

 

likewise, there visual basic example in following link shows managed server event source , com client event sink. managed server declares buttonevents event sink interface , connects interface button class. unmanaged client creates instance of button class , implements event sink interface.

please read article , try sample code: how to: raise events handled com sink
