vc如何实现快捷菜单的源码，有兴趣的朋友可以看下(vc how to source the shortcut menu, interested friends may have a look)

题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)

最近做了一个类似Windows画图板的小程序，拿来和大家分享一下。功能和界面全部模仿于Windows自带的画图板，界面如截图。功能主要有： 手绘线、简单图形、文字输入、图块拖放、重复撤销、画面缩放、打开保存图片文件，另外为了直接从数据库或者XML中存取图片，另外还提供了从Base64编码存取图片的接口，其他还实现了和画图板同样效果的工具箱及颜料盒。(Recently to do a similar drawing board a small Windows program, use and share with you. Features and interfaces in Windows, bringing all to imitate the drawing board, such as interface screenshot. The main features include: hand-painted lines, simple graphics, text input, drag and drop block, duplicate revoked, screen zoom, open the Save picture files, the other in order to directly from the database or XML access picture also provides a survival from the Base64 encoding Photos from the interface, the other also drawing board and achieve the same effect toolbox and paint boxes.)
