DirectX: Drawing a cube from struct array

Question

I'm creating a game and was looking to draw a cube in window. I completed a working function that fills a VERTEX structure with an obj file's vertex content. However, passing the output structure into the buffer seems to output 1 to 2 visible vertices (under D3D_PRIMITIVE_TOPOLOGY_POINTLIST, for debugging purposes) while the entire structure is printable.

Since I'm passing in raw vertices, is there something else I need to know? (Using DX11)

(Triangles are drawn. Squares seem to draw a triangle.(Under D3D_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP))

EDIT:

objv= GetObjData(FilePath, 1);
VERTEX *Cup = new VERTEX[objv.size()];
Cup = CreateVertexDS(objv, 1.0f, 1.0f, 1.0f, 1.0f);
int Cupsize=objv.size();
ObjSz=Cupsize; //Debugging purposes, sets a global variable: # of array elements.

Vertice are brought in,

D3D11_BUFFER_DESC BufferDescription;
ZeroMemory(&BufferDescription, sizeof(BufferDescription));

BufferDescription.Usage                   =D3D11_USAGE_DYNAMIC;
BufferDescription.ByteWidth               =sizeof(VERTEX)*ObjSz; //# of element from obj file.
BufferDescription.BindFlags               =D3D11_BIND_VERTEX_BUFFER;
BufferDescription.CPUAccessFlags          =D3D11_CPU_ACCESS_WRITE;
BufferDescription.MiscFlags               =0;

D3D11_SUBRESOURCE_DATA SRData;
ZeroMemory(&SRData, sizeof(SRData));
SRData.pSysMem=⋓

    Compile_Monitor = Device->CreateBuffer(&BufferDescription, &SRData, &D3DBuffer);
    if(FAILED(Compile_Monitor))
{
   MessageBox(hWnd, L"CreateBuffer() failed. Check for: \n Possible Bad or NULL value in D3D11_BUFFER_DESC struct.", 
                    L"Program Error!", 
                    MB_OK);
   PostQuitMessage(0);
}
    D3D11_MAPPED_SUBRESOURCE MappedResource;
    Compile_Monitor = DeviceContext->Map(D3DBuffer, NULL, D3D11_MAP_WRITE_DISCARD, NULL, &MappedResource);
    if(FAILED(Compile_Monitor))
{
   MessageBox(hWnd, L"Map() failed.", 
                    L"Program Error!", 
                    MB_OK);
   PostQuitMessage(0);
}
    memcpy(MappedResource.pData, &Cup, sizeof(Cup));
    DeviceContext->Unmap(D3DBuffer, NULL);
}

Data is rendered:

void Render(){
float ColorBlue[] = {0.4f,0.4f,0.4f,1.0f};
DeviceContext->ClearRenderTargetView(RenderTargetView,ColorBlue);
    UINT stride=sizeof(VERTEX);
    UINT Offset=0;
    DeviceContext->IASetVertexBuffers(0,1,&D3DBuffer,&stride,&Offset);
    DeviceContext->IASetPrimitiveTopology(D3D_PRIMITIVE_TOPOLOGY_POINTLIST);    

DeviceContext->Draw(ObjSz,0);
Swapchain->Present(0,0);

}

If the problem is loading the obj file, check this out: http://rastertek.com/dx11tut08.html. This particular example loads the data from an obj file and outputs it as its own file format, but the ReadFileCounts and LoadDataStructures functions combined should do exactly what you're looking for. Just anything between fin.close(); and fout.close(); in LoadDataStructures.

If the problem is rendering the VERTEX structure, I'll need its code as well.
