I am trying to create my render target view but I get this error from direct X

 A RenderTargetView cannot be created from a NULL Resource

To my knowledge it seems that I must fill the rendertarget pointer with data before passing it. But I am having trouble figure out how. Below is my declaration and implementation

declaration

#pragma once
#include "stdafx.h"
#include "resource.h"
#include "d3d10.h"
#include "d3dx10.h"
#include "dinput.h"


#define MAX_LOADSTRING 100

class RenderEngine {
protected:

    RECT m_screenRect;

    //direct3d Members
    ID3D10Device *m_pDevice; // The IDirect3DDevice10
    // interface
    ID3D10Texture2D *m_pBackBuffer; // Pointer to the back buffer
    ID3D10RenderTargetView *m_pRenderTargetView; // Pointer to render target view
    IDXGISwapChain *m_pSwapChain; // Pointer to the swap chain
    RECT m_rcScreenRect; // The dimensions of the screen

    ID3DX10Font *m_pFont; // The font used for rendering text
    // Sprites used to hold font characters
    ID3DX10Sprite *m_pFontSprite;

    ATOM RegisterEngineClass();
    void Present();

    TCHAR m_szWindowClass[MAX_LOADSTRING];          // the main window class name

    void DrawTextString(int x, int y, D3DXCOLOR color, const TCHAR *strOutput);

    int Run();

    RenderEngine()
    {
        m_screenRect.right = 800;
        m_screenRect.bottom = 600;
    }

};

my implementation
