It's *exactly* what I posted except that the object was derived
from TStringGrid and instead of using AllocateHWnd, I passed
the grid's Handle to OpenThemeData.

I haven't had a chance to test it yet but I'm of the opinion
that the HWND is a moot point as far as the theme drawing is
concerned because the drawing functions that I'm looking at
want an HDC and a RECT. I'm thinking that as long as I get it
opened, I can draw in the fashion as determined by the LPCWSTR
parameter.

I did initially but because I had problems, I reverted to what
*I* knew to be true. The win32 help was a bit fuzzy to me.

Not true. UxTheme.dll can be present and theming enabled but
you still need to check the Major version for ComCtl32 because
to do theming, a manifest file must still exist. If it does
not exist, ComCtl32 returns 5 as the major version number
instead of 6.
