vs2010MFC想要在picture或static控件中显示jpg图片如何改写下面的代码？

//在屏幕上显示JPG图像
void CollectionDlg::DrawImage(int x, int y, CDC *pDC)
{

if (pPicture != NULL)
{
long nWidth,nHeight;

pPicture->get_Width( &nWidth );

pPicture->get_Height( &nHeight );

    //图片原大显示
    CSize sz(nWidth, nHeight );
    pDC->HIMETRICtoDP( &sz );
    pPicture->Render(pDC->m_hDC,x,y,sz.cx,sz.cy,0,nHeight,nWidth,-nHeight,NULL);            

    //////按窗口尺寸显示
    //      CRect rect;
    //      GetClientRect(&rect);
    //      pPicture->Render(pDC->m_hDC,x,y,rect.Width(),rect.Height(),0,nHeight,nWidth,-nHeight,NULL);
}

}
