MFC中picture控件显示图片

1.打开BMP图片

CBitmap* m_pBitmap = new CBitmap;
m_pBitmap->LoadBitmap(IDB_BITMAP1);2.第一种方式，用CDC显示
CDC *pDC = GetDlgItem(IDC_AAAA)->GetDC(); //IDC_XXXX是你的图片控件

CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
CBitmap *pOldbmp = dcMem.SelectObject(m_pBitmap); //m_bmp是你获得的CBitmap对象
pDC->BitBlt(0, 0, 100, 100, &dcMem, 0, 0, SRCCOPY); //bmWidth,bmHeight是你的CBitmap对象宽和高
dcMem.SelectObject(pOldbmp);3.第二种方式：用HDC显示
HDC dcMem;
dcMem = CreateCompatibleDC(hDCa);
SelectObject(dcMem, (HBITMAP)m_pBitmap->GetSafeHandle()); //m_bmp是你获得的CBitmap对象
BitBlt(hDCa,0, 0, 100, 100, dcMem, 0, 0, SRCCOPY); //bmWidth,bmHeight是你的CBitmap对象宽和高
dcMem.SelectObject(pOldbmp);
