I wanted to create a mesh from the code...and to put my vertexBuffer,IndexBuffer inside in order to create the normals for the each vertex in my buffer.(using the computeNormals of the mesh) I don't know what's wrong here but i get an overflow error,..



        Dim auxMesh As Mesh = Nothing
        auxMesh = New Mesh(HeightMapCls.BmpWidth * HeightMapCls.BmpHeight / 3, HeightMapCls.BmpWidth * HeightMapCls.BmpHeight, MeshFlags.SystemMemory, MyVertexType.Format, device)

        auxMesh.VertexBuffer.SetData(HeightMapCls.verts, 0, 0)
        auxMesh.IndexBuffer.SetData(HeightMapCls.indexArray, 0, 0)

        auxMesh.ComputeNormals()

        VertexCls.vertexBuffer = auxMesh.VertexBuffer
        VertexCls.indexBuffer = auxMesh.IndexBuffer


        device.SetStreamSource(0, VertexCls.vertexBuffer, 0)
        device.Indices = VertexCls.indexBuffer

The...number of faces parameter should be: vertexNR/3 no?,..hmmm what could be?

You should probably take a look at the MeshFromOBJ sample that comes with the SDK. That sample shows how to initialize an ID3DXMesh object with data gathered from any source. The mesh specifically gathers the data from a Wavefront Object file (.obj) but all you need to look at is how they create and initialize the mesh once they have the data available.
