Branching fraction measurements using B-meson decays to K{sub S}{sup 0}{pi}{sup +}{pi}{sup -} are presented. These measurements were obtained by analyzing a data sample of 88.9x10{sup 6} {upsilon}(4S){yields}BB-bar decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B(B{sup 0}{yields}K{sup 0}{pi}{sup +}{pi}{sup -})=(43.7{+-}3.8{+-}3.4)x10{sup -6}, B(B{sup 0}{yields}K*{sup +}{pi}{sup -})=(12.9{+-}2.4{+-}1.4)x10{sup -6}, and B(B{sup 0}{yields}D{sup -}({yields}K{sub S}{sup 0}{pi}{sup -}){pi}{sup +})=(42.7{+-}2.1{+-}2.2)x10{sup -6}. The CP violating charge asymmetry A{sub K*{pi}} for the decay B{sup 0}{yields}K*{sup +}{pi}{sup -} was measured to be A{sub K*{pi}}=0.23{+-}0.18{sub -0.06}{sup +0.09}. For all these measurements the first error is statistical and the second is systematic.
