CDocument::GetFirstViewPosition
virtual POSITION GetFirstViewPosition() const;
返回值：
返回POSITION值，它用于GetNextView成员函数的迭代。
说明：
调用该函数获得与文档相关的视图列表中的第一个视图。
示例：
// To get the first view in the list of views:
POSITION pos = GetFirstViewPositon ();
CView* pFirstView = GetNextView( pos );
// This example uses CDocument::GetFirstViewPosition
// and GetNextView to repaint each view.
void CMyDoc::OnRepaintAllViews()
{
POSITION pos = GetFirstViewPosition();
while (pos != NULL)
{
CView* pView = GetNextView(pos);
pView->UpdateWindow();
}
}
// An easier way to accomplish the same result is to call
// UpdateAllViews(NULL);
