A high statistics sample of photo-produced charm from the FOCUS(E831) experiment at Fermilab has been used to search for direct CP violation in the decays D+->K_S pi+ and D+ ->K_S K+. We have measured the following asymmetry parameters relative to D+->K-pi+pi+: A_CP(K_S pi+) = (-1.6 +/- 1.5 +/- 0.9)%, A_CP(K_S K+) = (+6.9 +/- 6.0 +/- 1.5)% and A_CP(K_S K+) = (+7.1 +/- 6.1 +/- 1.2)% relative to D+->K_S pi+. The first errors quoted are statistical and the second are systematic. We also measure the relative branching ratios: Gamma(D+->bar{K0}pi+)/Gamma(D+->K-pi+pi+) = (30.60 +/- 0.46 +/- 0.32)%, Gamma(D+->bar{K0}K+)/Gamma(D+->K-pi+pi+) = (6.04 +/- 0.35 +/- 0.30)% and Gamma(D+->bar{K0}K+)/Gamma(D+->bar{K0}pi+) = (19.96 +/- 1.19 +/- 0.96)%.
