单应用程序获得文档类对象指针和获得视图类对象指针办法

获得View指针:

 POSITION pos = this->GetFirstViewPosition();

 CPointCloudMeasureView *pView = NULL;

 if(pos)

  pView = (CPointCloudMeasureView *)this->GetNextView(pos);

 else

  ASSERT(false);

获得view指针的关键在于GetFirstViewPosition函数和GetNextView函数;

获得Doc指针:

 CDocument* pDoc  = ((CFrameWnd*)AfxGetMainWnd())->GetActiveDocument(); 

 ASSERT_VALID(pDoc);

 if (!pDoc)

  return false;
