Direct3D font not showing up

I'm writing a simple game engine and the first thing I decided to do was to make it output text, but the problem is the text wont show up
Here is my code

Code:

//Initializing font and sprite object
hr = D3DX10CreateSprite(m_pD3DDevice, 512, &m_pSpriteObject);
	if(hr != S_OK)
		MessageBox(NULL, TEXT("Can't create the sprite object"), TEXT("ERROR!"), MB_OK);

if(FAILED(D3DX10CreateFont(m_pD3DDevice, 30, 0, FW_BOLD, 1, FALSE, DEFAULT_CHARSET, OUT_DEFAULT_PRECIS, DEFAULT_QUALITY,
		DEFAULT_PITCH | FF_DONTCARE, TEXT("Helvetica"), &m_pFont)))
		  return FALSE;

Code:

//Render function
void GameEngine::Render()
{
	m_pD3DDevice->ClearRenderTargetView(m_pRenderTargetView, D3DXCOLOR(0.0f, 0.0f, 0.0f, 0.0f));

	m_pSpriteObject->SetProjectionTransform(&m_mxProjection);

	GamePaint();

	m_pSwapChain->Present(0, 0);
}

Code:

//Game Paint Function
void GamePaint()
{
	g_pGame->DrawText(TEXT("This is a test"));
}

Code:

//Draw Text Function
void BimanEngine::DrawText(LPCWSTR szText)
{
	RECT rect;
	SetRectEmpty(&rect);
	//Get the size of rect
	HRESULT hr = m_pFont->DrawTextW(NULL, szText, -1, &rect, DT_CALCRECT | DT_LEFT, D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f));
	if(FAILED(hr))
		MessageBox(m_hWindow, TEXT("DrawText failed"), TEXT("Error"), MB_OK);
	//Display rect
	hr = m_pFont->DrawTextW(m_pSpriteObject, szText, -1, &rect, DT_LEFT, D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f));
	if(FAILED(hr))
		MessageBox(m_hWindow, TEXT("DrawText failed"), TEXT("Error"), MB_OK);
}

Thank you in advance
