Thank you for your response. In other words, I can't even change colours of certain entries in the combo box?? This is because I thought that if its not possible to disable some entries, then I might change the colour to white so that it may not be visible to the user.. Would you or anyone have other suggestions of how to work around this problem??

Entries in a combo or a listbox are accessed as cbo.List(n) which retrieves the item string. The only property of these items is if they are selected or not. This property is accessed as cbo.Selected(n).
An 'Enabled' property does not exist. You have to deal with that by software.
