It depends on rowsource how quickly you could do it.
-You could check combo elements in a loop :

lnColNumber = < col number where your unique values are >
with thisform.blah.blah.myCombo
  for ix = 1 to .ListCount
    if .List(ix, lnColNumber) = lcMyCheckVAlue && exists
     * do whatever
     exit
    endif
  endfor
endwith

-You could use ascan() if rowsource is array.
-You could use select directly or scan..endscan, locate etc. if rowsource was a SQL or something like that.
