Help with options for GuiCtrlCreateCombo

[pacman1176]

When you create a combo with items, you have the ability to scroll through them. Also, if you type in the GUI combo, your text writes over the given values. Is there any way to disable the user from typing in the values, but rather when typing say 'a', it scrolls down to the next value starting with 'a', sort of locking the combo?
