ComboBox to Show what it's introduced

Hi,

I'm struggling with a ComboBox.

i've managed to introduce several items by default. But he problem comes when I want to introduce a new one and display it as it's being typed.

So Ideally I'd like to show by default one of the Inputs introduced automatically. But also allow to introduce a new item.

I've used the event of the ComboBox KeyPress and it partially works.

I'd appreciate any hint of who had done similar stuff?

Regards

macro attached.
