E:\Visual_C__MFC擴展編程實例 例18
動態(tài)地抓取應用程序的屏幕圖像并將其打印。
上一個實例打印的是文檔的報表，而不是當前出現(xiàn)在屏幕上的內容。在本例中，將實現(xiàn)
屏幕抓取并打印其內容。M F C 為打印視提供了有限的支持， 但只要用M F C 在
C Vi e w : : O n D r a w ( )中所提供的設備環(huán)境，就可以繪制自己的視。在打印視的時候， M F C只需調
用具備打印機設備環(huán)境的O n D r a w ( )函數(shù)即可。但是，如果不繪制自己的視，例如，用一個或
者一個以上的控件窗口填充自己的視就不會打印任何東西。每個控件將使用自己的設備環(huán)境
將自己打印到屏幕，因此打印視的唯一途徑就是抓取屏幕(拷貝其內容到一個位圖對象)并將其
打印到打印機。由于該功能整個與位圖相關，因此將該功能封裝到了位圖類中。

Description:
There is a pile of n wooden sticks. The length and weight of each stick are known in advance. The sticks are to be processed by a woodworking machine in one by one fashion.
