You necessarily have to implement an owner-draw combo box.
In particular follow the following steps:
1) Derive your own class from MFC's CComboBox
2) Implement the virtual functions you need among DrawItem(), MeasureItem(), CompareItem() and DeleteItem(). They allow you to put your custom drawing code to accomplish extended appearances.
You may also want to store additional data for the multiple columns of your combo boxes; add some data members to your CComboBox derived class and refer to them in your owner drawing code.

I am sending a copy of this answer to the two E-Mail addresses you gave, too. Remember to grade this answer on Expert Exchange anyway!
