C / C++ / MFC

Hi,
I need draw a border color to static Frame control, 
I have the code as below but it not work with my testing for static Frame and Window Dialog.
Please see the code and help me for this

void CTestDLLDlg::DrawFrameBorder(HWND hWnd,COLORREF refColor)
{
	RECT stRect;

	// Get the coordinates of the window on the screen
	::GetWindowRect(hWnd, &stRect);
	
	// Get a handle to the window's device context
	HDC hDC = ::GetWindowDC(hWnd);

	HPEN hPen;
	hPen = CreatePen(PS_INSIDEFRAME, 2* GetSystemMetrics(SM_CXBORDER), refColor);
	
	// Draw the rectangle around the window
	HPEN   hOldPen   = (HPEN)SelectObject(hDC, hPen);
	HBRUSH hOldBrush = (HBRUSH)SelectObject(hDC, GetStockObject(NULL_BRUSH));
	
	Rectangle(hDC, 0, 0, (stRect.right - stRect.left), (stRect.bottom - stRect.top));

	//Give the window its device context back, and destroy our pen
	::ReleaseDC(hWnd, hDC);

	SelectObject(hDC, hOldPen);
	SelectObject(hDC, hOldBrush);

	DeleteObject(hPen);
	DeleteObject(hDC);
}

At initialize function I called as bellow:

BOOL CTestDLLDlg::OnInitDialog()
{
 CWnd* pWnd = GetDlgItem (IDC_AVATAR1);

 DrawFrameBorder(pWnd->m_hWnd,RGB(255,0,0))//red
 //and for test more: DrawFrameBorder(this->m_hWnd,RGB(255,0,0))//red
 return true;
}
 But it seem to not draw the red border

Please help me
Thank in advance!
