MFC中設置某個VIEW為當前視圖

    //MainFrame中獲取Doc，通過Doc遍歷視圖
    CCR17CADDoc *pDoc = (CCR17CADDoc *)GetActiveDocument();
    CCR17CADView *pCADView = NULL;
    if (pDoc != NULL)
    {
        POSITION posView = pDoc->GetFirstViewPosition(); 
        while(posView)
        {      
            CView *pView = (CView *)pDoc->GetNextView(posView);
            //如果是我們要找的視圖，設置為當前視圖，並跳出循環
            if(pView->IsKindOf(RUNTIME_CLASS(CCR17CADView)))   
            {
                pCADView = (CCR17CADView *)pView;
                SetActiveView(pCADView);
                break;      
            }
        } 
    }
