Problem with Animation

Hi,
I have written a code to perform animation using Visual Studio 2008. It has got mountains, a road and a car. The car has to travel on the road. But when i execute the program a grey window slowly captures my screen. Due to large size i am skipping the default code.
The *view.cpp file is:

// AnimationCarView.cpp : implementation of the CAnimationCarView class
//



// CAnimationCarView

IMPLEMENT_DYNCREATE(CAnimationCarView, CView)

BEGIN_MESSAGE_MAP(CAnimationCarView, CView)
	// Standard printing commands
	ON_COMMAND(ID_FILE_PRINT, &CView::OnFilePrint)
	ON_COMMAND(ID_FILE_PRINT_DIRECT, &CView::OnFilePrint)
	ON_COMMAND(ID_FILE_PRINT_PREVIEW, &CView::OnFilePrintPreview)
	ON_WM_TIMER()
	ON_WM_ERASEBKGND()
	ON_WM_CREATE()
END_MESSAGE_MAP()

// CAnimationCarView construction/destruction

CAnimationCarView::CAnimationCarView()
{
	// TODO: add construction code here
    i=150,j=190,k=145,l=140,m=138,n=195,o=197,p=170,q=148,r=185;
	penGrey.CreatePen(PS_SOLID, 5, RGB(128,128,128));//GREY color
	penLGrey.CreatePen(PS_SOLID,5, RGB(220,220,220));//LGREY color
	penBlack.CreatePen(PS_SOLID, 5, RGB(0,0,0));
	pOldPen=NULL;
	brGrey.CreateSolidBrush(RGB(128, 128, 128));
	brLGrey.CreateSolidBrush(RGB(220,220,220));
	brBlack.CreateSolidBrush(RGB(0, 0, 0));
	pOldBrush=NULL;
	
}
