We present a  preliminary measurement of  the CP-violating parameters in
fully reconstructed B->D^(*)+-pi-+ and B->D^+-rho-+ decays in
approximately 232 million Y(4S)->BBbar decays collected with the
BaBar detector at the PEP-II asymmetric-energy B factory at SLAC.
From a  maximum likelihood fit to the time-dependent decay distributions we obtain for
the parameters related to the CP violation quantity sin(2beta+gamma):

a[Dpi]     = -0.013 +/- 0.022 (stat.) +/- 0.007 (syst.),
clep[Dpi]  = -0.043 +/- 0.042 (stat.) +/- 0.011 (syst.),
a[D*pi]    = -0.043 +/- 0.023 (stat.) +/- 0.010 (syst.),
clep[D*pi] =  0.047 +/- 0.042 (stat.) +/- 0.015 (syst.),
a[Drho]    = -0.024 +/- 0.031 (stat.) +/- 0.010 (syst.),
clep[Drho] = -0.098 +/- 0.055 (stat.) +/- 0.019 (syst.).
