typecasting -1 value

[RyanEK]

Hello,

I have come across something peculiar. When typecasting -1 in a combobox (or any other component for that matter), and then try to retrieve the value back
ie.

integer(ComboBox1.items.objects[ComboBox1.itemindex]);

... I get an EStringListError. However it works with any other -ve value.

Does anyone know how to overcome this problem?

thanks

Could you elaborate on what you're trying to do and why?

Isnt this because the '-1' value as applied to this and other componets is used as a flag to indicate that no strings (or objects) are present. and so cannot be evaluated as such.
in effect you are trying to use an invalid index.
