Issue with Active X Component

I have created an active x component using wizard in Visual studio 2010. I am consuming the OCX control in a .net desktop application. Now the problem is that. I have modified a particular function exposed from the control after using the control some days in the .net application. i have changed the number of parameters in the function by directly editing that from code file. the

Code:

---

dispinterface _DXXX        {
                properties:
                methods:
                        [id(1)] // Here

DISP_FUNCTION_ID( FnName, .. //Here

---

And implementation and declaration of the function. The issue now is that the changes are not reflecting in the .NET code side. What to do for that

Re-import type library?

Sorry it was my fault, i was using the wizard and forget to remove the old imported assembly reference before adding the new ocx control to the application. Thanks for remembering about the import option Igor :-)
