Hi Supra,
I don't know how those Comboboxes look like, but I imagine they are ownerdrawn comboboxes.
You can quite easily create them yourself.
Set ComboBox.DrawMode to one of the OwnerDrawn ones.
Handle the DrawItem event and draw each item as you see fit (one event per item).
Set DropDownStyle to DropDownList to see the ownerdrawn item in the textbox.
