Window Caption size change?

Hi,
I have a regular application window (created with WTL) and I need to make its caption bar thicker (taller) than then standard size. How can I do this programmatically without custom drawing the non-client area myself (handling the WM_NCPAINT message)?
I need to this this only for my window's caption bar (the title bar) and changing the system setting to apply to the whole system is not an option.
Thanks,

You can't. Caption sizes are global.

You will either need to do NC painting, or you will need to create a captionless window, and do all the painting yourself, simulating a caption.

If you can limit yourself to Vista and the glass UI, you can extend the glass effect into the client area making it appear to have a larger caption (DwmExtendFrameIntoClientArea), but this will still need you to do NC painting

Thank you, OReubens.
