In this approach, we calculate non-factorizable and annihilation type contributions, in addition to the usual factorizable contributions. Our result is in agreement with the measured branching ratio of $B^0/\\bar B^0 \\to \\pi^\\pm\\rho^\\mp$, $B^\\pm \\to \\pi^\\pm\\rho^0$, $\\pi^\\pm \\omega$ by CLEO and BABAR collaboration.
