创建了位图应该怎么销毁

Question

BOOL CZLLKView::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
//  the CREATESTRUCT cs
bitmap1.LoadBitmap(IDB_BITMAP_FOREFACE);
bitmap2.LoadBitmap(IDB_BITMAP_FACE);

return CView::PreCreateWindow(cs);
}/////////////////////////////////////////////////////////////////////////////
// CZLLKView drawingvoid CZLLKView::OnDraw(CDC* pDC)
{
CZLLKDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here CRect rcBlock;
rcBlock.SetRect(0,0,660,640);
pDC->FillSolidRect(&rcBlock,RGB(0,0,250));
CDC dcMemory1,dcMemory2;
    dcMemory1.CreateCompatibleDC(pDC); 
    dcMemory1.SelectObject(&bitmap1);

   dcMemory2.CreateCompatibleDC(pDC);
    dcMemory2.SelectObject(&bitmap2);
就象这个,应该在哪Delete呢

Answer 1

MFC类的话不需要你delete，类析构时会自动处理的，当然可以手动delete: OnDraw最后可以dcMemory1.DeleteObject();dcMemory2.DeleteObject(); bitmap1,bitmap2可以在OnDestory或析构函数里DeleteObject()
