Allowing End User to Select Only From Combobox

Hello, I am trying to prevent an end-user from typing in a combobox. I want them to only select from the options that are loaded in the combobox. I know this is possible in VB6.0, but i cannot for the life of me find how to do this in vb.net. Any help into this would be greatly appreciated. I'm not sure if its me being blind, or if there is a workaround required. Thank You Very Much. Wiggum
