In this article, we study the vertices DDV and D^*DV with the light-cone QCD sum rules. The strong coupling constants gDDV and fD^*DV play an important role in understanding the final-state re-scattering effects in the hadronic B decays. They are related to the basic parameters β and λ respectively in the heavy quark effective Lagrangian, our numerical values are smaller than the existing estimations.
