Determine if PC running XP View or Classic View

[cfpsoft]

I have a form consisting of a proprietary scheduler component and a label, situated in a way similar to:

+-------------------------------------------
| Scheduler |
| | |
+-------------------------------------------------
| label
+------------------------------------------------

My problem occurs when this form is maximised. The display is fine in classic view - however, if I switch to XP view, I lose a portion of the label, because of the increased height of the XP view toolbar.

Can anyone point me in the right direction to determine which view I am running in, or does anyone have a "fudge factor" that will work regardless of view?

Thanks in advance
