How can I dynamically add selection values to my Combobox controls

Hi Experts,
I use about 10 Combobox controls in my VB.Net application. The controls names all begin with "cboResult".  I want to loop through all my Combobox controls whose name begins with "cboResult" and add "Yes", "No", and "N/A" as possible selection values (i.e. Items.Add("YES"), etc...).  How can I do this?

Thanks in advance,
