applying texture another problem directx c++

Question

ok i got everything working. the texture only applys for two sides only of the cube the other sides won't display the correct texture.
here is my code

Take a look at the texture coordinates for your triangles: the triangle (4, 0, 6) has texture coordinates (0, 0), (0, 0), (0, 1), which isn't going to look right! You may have to create additional vertices with merely different texture coordinates to achieve what you want.
