VertexBuffer->Lock and stl::vector

[aker_y3k]

I am trying to use IDirect3DVertexBuffer9::Lock and pass an stl::vector containing my vertex structure, as data, instead of a VERTEX3* data pointer.

Can someone help me, becuase it crashes. Here is my code:

    meshes.pVB->Lock(iNextVertexData,iDataSize,(void**)&meshes.pVertices,flags);
        memcpy((void*)&meshes.pVertices.back(),&ver,iDataSize);
    meshes.pVB->Unlock(); 

Ignore the iNextVertexData and iData variables, I would be grateful if you helped me for the Lock and 3rd parameter only. It crashes on memcpy, so I guess a proper lock isnt done.

Let me see your vector declaration.

I figured it out, thanks anyway. I used a temporary void* to store my vertices.
