Scroll en combobox y Listbox Excel
Podría ayudarme a hacer que un combobox que cargue con datos de columnas de excel son como 50 en lista me funcione el scrool del mouse ya que por ahora solo puedo desplazar la barra lateral lo cual no es muy practico.

¡Gracias! Dante. Funciona ala perfección en offfice 2010 con w7 de 32 bits. Pero cuanto copio este mismo código en office2013 64 bits en un ordenador w8 de 64 bits me sale error. Que tendría que cambiar para que funcione en ambos equipos.
