一道程序题： 如何在MFC中的对话框按钮函数中获得CDocument指针从而对CDocument中数据进行操作

Answer 1

MSDN上的例子：
//To get the first view in the list of views:
POSITION pos = GetFirstViewPosition();
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);

主要是用什么API取指针！比如在Doc中取得View的指针
