I've setup a child window with a horizontal scroll bar, and am now trying to
make the scroll bar do something.  Unfortunately, what I get are not
WM_HSCROLL messages to the child window, but WM_SYSCOMMAND messages with
wParam set to SC_HSCROLL.  lParam appears to be the mouse coordinates.

This is, of course, not terribly useful, as the SB_* type information doesn't
seem to be present.  I checked everywhere I could think of in volume 1 of
the SDK reference, in the guide to programming, and in Petzold.  No joy.

Has anyone experience with scroll bars in child windows?  Is there a way to
do something useful with the resulting WM_SYSCOMMAND?

Thanks.
