通过COM获取microsoft help viewer2.0 的收藏列表

打开microsoft help viewer2.0，切换到favorites窗口。添加列表框，变量名为m_list1;在OnInitDialog里面添加： CListCtrl* lst1 = (CListCtrl*)GetDlgItem(IDC_LIST1);lst1->ModifyStyle( 0, LVS_REPORT );               // 报表模式  lst1->SetExtendedStyle(lst1->GetExtendedStyle() | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT| LVS_EX_CHECKBOXES);  lst1->InsertColumn(0,_T("Favorites List")); lst1->SetColumnWidth(0,600); 新建一个button，在button里面添加如下代码：HRESULT hRes;HWND MainHwnd;TCHAR tcMainHwnd[MAX_PATH] = {0};//新建一个文本输入框，用SPY++获取microsoft help viewer 2.0 的类名m_edit.GetWindowTextW(tcMainHwnd, MAX_PATH);//tcMainHwnd 为microsoft help viewer 2.0 的类名MainHwnd = ::FindWindow(tcMainHwnd, NULL);if(!MainHwnd){AfxMessageBox(L"DEBUG: Unable to find main IE window");return;}IAccessible *MainHwndAccess;if(AccessibleObjectFromWindow(MainHwnd, OBJID_WINDOW, IID_IAccessible, (void **)&MainHwndAccess) != S_OK){AfxMessageBox(L"DEBUG: Unable to get IAccessible interface");return;}long inMainHwndCount = 0;hRes = MainHwndAccess->get_accChildCount(&inMainHwndCount);if(!SUCCEEDED(hRes)){AfxMessageBox(L"DEBUG: Unable to get Objects count");return;}long outMainHwndCount = 0;VARIANT vMainHwnd[MAX_PATH];hRes = AccessibleChildren(MainHwndAccess, 0, inMainHwndCount, vMainHwnd, &outMainHwndCount);if(!SUCCEEDED(hRes)){AfxMessageBox(L"DEBUG: Unable to get objects");return;}for(int i = 0;
