CBitmap和HBITMAP的区别及相互转换方法

CBitmap bmp;
bmp.LoadBitmap(IDB_BITMAP1);
HBITMAP hbm = (HBITMAP)bmp;
CBitmap bmp1;
bmp1.Attach(hbm);

HBITMAP = CBitmap.m_hObject
CBitmap* = CBitmap.FromHandle(HBITMAP)

//已知HBITMAP hbit;
CBitmap cb;
cb.FromHandle(hbit);

//已知CBitmap cb;
HBITMAP hbit=(HBITMAP)cb;

CBitmap bmp;
HBITMAP hBmp;
相互转换：
hBmp=(HBITMAP)bmp.GetSafeHandle();
bmp.Attach(hBmp);
