ownerdrawn window caption bar with xp

Hi,

I developed an ownerdrawn caption bar, that has some extra buttons beside the standard max/min/restore/close controls. The standard controls are draw with

dc.DrawFrameControl(&rc, DFC_CAPTION, DFCS_CAPTIONRESTORE);

This works fine except with Windows XP (new look activated).

XP draws always the old controls. Any idea, how to draw the new looking controls?

Thanks,

Christian
