VB在显示大图片时候，自动为窗体添加滚动条功能，当在窗口中显示大图片的时候，自动在窗体右侧添加可拖动的滚动条。程序本身是很小的，不过供测试用的图片有1M多，所以源码包有些大哦。-VB big picture is displayed when the form is automatically added to the scroll bar function, when the big picture is displayed in the window of time, automatically added to drag the scroll bar on the right side of the form. Program itself is very small, but for testing purposes pictures have more than 1M, so some big oh source packages.
