ComboBox on Toolbar

Does anyone knows how to create a ComboBox on a Toolbar.
Lets pretend I want to have a ComboBox with a predefined list of documents to open, on a SDI Toolbar aplication.... how can I implement this idea..... does anyone has a small tutorial that can help me out ??

Thanks.

Old version of Petzold had this example. I think it was 4th edition and if I
remember right, I have stumbled on source code of the Petzolds on the
Internet somewhere.

Did you try this?
