Routine Description:
This routine creates the optional component selection page using

Arguments:
OcManagerContext - supplies Optional Component Manager context,

DetailsPageControlsInfo - supplies information about the controls in the
template for the top-level/wizard page.
Return Value:
Handle to newly created property sheet page, or NULL if failure
(assume out of memory in this case).

the listbox for a specific level in the hierarchy.)
This includes handling the small icons and selection state icons.
The 0th element is selected.
Arguments:
OcPage - supplies OC page context structure.
List - supplies handle to list box control to be populated.
DesiredParent - supplies string id of subcomponent that is the parent
of the level we care about. -1 indicates the topmost level.
Return Value:
