MFC中设置某个VIEW为当前视图

    //MainFrame中获取Doc，通过Doc遍历视图
    CCR17CADDoc *pDoc = (CCR17CADDoc *)GetActiveDocument();
    CCR17CADView *pCADView = NULL;
    if (pDoc != NULL)
    {
        POSITION posView = pDoc->GetFirstViewPosition(); 
        while(posView)
        {      
            CView *pView = (CView *)pDoc->GetNextView(posView);
            //如果是我们要找的视图，设置为当前视图，并跳出循环
            if(pView->IsKindOf(RUNTIME_CLASS(CCR17CADView)))   
            {
                pCADView = (CCR17CADView *)pView;
                SetActiveView(pCADView);
                break;      
            }
        } 
    }
