Creating an ocx from a Usercontrol made with VB Net ????

Question

I developped a long time ago a program to manage photos. This program works fine but I would like to add more functions like rotation, modifications on that photos. It's quite impossible to migrate it to VB Net as it is using a lot of functionalities that are too complex for the migration wizard. Then I decided to modify only the usercontrol I made previously with VB 6, writing it with VB net, creating an ocx file and using it in my VB6 program. Is ther somebody who knows how I can do to create an ocx file from VB Net ???? Thanks a lot.
