Very Hard Frame/view/doc question!
-
:I want to Create a Frame/view/doc structure On a ActiveX Control,but It will be Found Memory leak! And I Found that the reasons is : CDocManager* CDocManager::pStaticDocManager; CPtrList* CDocManager::pStaticList; How Can I avoid Memroy leak? the Following is My Code : BOOL Create() { if( m_pFrameWnd ) { if( IsWindow(m_pFrameWnd->m_hWnd) ) return TRUE; } CSingleDocTemplate * pDocTemplate; pDocTemplate = new CSingleDocTemplate(IDR_MAPTYPE, RUNTIME_CLASS(CMapDoc), RUNTIME_CLASS(CMapFrame), RUNTIME_CLASS(CMapView)); CMapDoc * pDoc = new CMapDoc; CCreateContext Context; Context.m_pCurrentDoc = pDoc; Context.m_pNewDocTemplate = pDocTemplate; Context.m_pNewViewClass = RUNTIME_CLASS(CMapView); Context.m_pLastView = NULL; Context.m_pCurrentFrame = NULL; CMapFrame * pFrameWnd = new CMapFrame; m_pDoc = pDoc; m_pFrameWnd = pFrameWnd; m_pDocTemplate = pDocTemplate; CRect rcMap; GetClientRect(&rcMap); BOOL ret = m_pFrameWnd->Create(AfxRegisterWndClass(CS_DBLCLKS), NULL, WS_CHILD|WS_VISIBLE, rcMap,this,NULL,&Context); m_pFrameWnd->ShowWindow(SW_SHOW); return ret; }:(( ZHANGYIFEI

MFC only deletes the CDocManager class if it(MFC) created it. It looks like you are creating your own doc manager and therefore need to delete on exit.
I have not created CDocManager ,I don't want MFC create it too!but In fact ,MFC Create it,and leak happened! the reason is two CDocManager's static data member! ZHANGYIFEI
