There is no need to allocate and write into your own buffer then copy
the content, you can directly write into the vertex buffer.

A more important issue: MSDN says "The ID3DXLine interface implements
line drawing using textured triangles", which is probably true (as far
as I know there is otherwise no support in D3D9 to
antialiased/stippled/wide lines, which are instead supported by
ID3DXLine). So, drawing with D3DPT_LINESTRIP primitives in general is
probably not the right way...
