If so do I at somepoint in time have to do a EM_SETFORMAT first ????

lParam
Pointer to a CHARFORMAT structure. If the selection formatting
is being retrieved, the structure receives the attributes of
the first character and the dwMask member specifies which
attributes are consistent throughout the entire selection.
