If you open up MS Word in Office 97, and you have the drawing menu bar up, select "LineStyle" and then "More Lines", and a tabbed dialog comes up, titled "Format Autoshape", and in the "Colors and Lines" tab, note how the combo boxes show bitmaps (or colors) inside instead of text.
Also note when you click the drop down arrow, how the menu appears, with bitmaps, and mouse over highlight. I need to implement something very similar to this. Anyone know how they did it ? There doesn't seem to be any members of the CComboBox class that directly allow you to do the same thing.
