VC++制作窗口内的浮动菜单和工具栏实例，像标准的窗口菜单和工具栏类似，只不过通过处理后，菜单和工具栏可以从主窗体中分享，浮动在屏幕的任意位置，可关闭浮动菜单和工具栏，像Office软件中，类似的菜单工具条随处可见，按住菜单头部的竖条即可把菜单从主窗口中分离。(Variation within the vc++ to make the window menu and toolbar example, as a standard window menus and toolbars are similar, only after processing, menus, and toolbars can share, from the main form of floating on any position of the screen, can be closed floating menus and toolbars, like Office software, similar to the menu bar can be seen everywhere, hold down the menu bar of the head to the menu from the main window. )

古今中外，许多人致力于圆周率的研究与计算。为了计算出圆周率的越来越好的近似值，一代代的数学家为这个神秘的数贡献了无数的时间与心血。十九世纪前，圆周率的计算进展相当缓慢，十九世纪后，计算圆周率的世界纪录频频创新。整个十九世纪，可以说是圆周率的手工计算量最大的世纪。-ancient times, many people committed to the ratio of the circumference research and calculation. In order to calculate the ratio of the circumference increasingly good approximation, the generations of mathematicians for the mysterious few of the numerous contributions of time and effort. Before the 19th century, the ratio of the circumference calculated Progress has been very slow and 19th centuries, we have calculated the ratio of the circumference of World Records frequently innovation. Throughout the 19th century, it is the ratio of circumference to the manual calculation of the largest in the century.
