1. 设计一个窗体应用程序，模拟写字板应用程序的基本功能。具体功能要求如下： （1）“文件”菜单中有“新建”、“打开”、“保存”、“退出”子菜单。 （2）“编辑”菜单中有“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”子菜单。 （3）工具菜单中有“颜色”、“字体”、“状态栏”功能。 （4）帮助菜单中有“关于”菜单功能。 （5）实现“编辑”菜单中、“工具”栏目中“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”的功能。 （6）实现文件的新建、打开、保存功能。（利用RichTextBox控件） （7）文件菜单添加打开文本文件、保存文本文件菜单项，实现文件的打开、保存功能。（利用文件读写类） 提示： （ 1 ）添加菜单栏、工具栏、 RichTextBox 控件。 （ 2 ）在打开对话框中要想只显示文本文档，可以在通用对话框 Filter 属性中设置 *.txt 类别。 richTextBox 的 LoadFile 、 SaveFile 方法中要指定文件流为 RichTextBoxStreamType.PlainText （ 3 ）点击菜单和工具栏相关按钮都实现同一个功能，所以会调用同一个方法。设计一系列公有方法实现相关功能。建议完成一个方法，就运行测试一个方法，问题解决后再编写下一个方法，避免出现太多错误。 1 using System; 2 using System

I usually end up adding a method named EvChanged to indicate a .Net event Changed. What is the right way to show that a type publishes a specific event? 回答1: 回答2: I find onEventName() the easiest naming scheme for event callbacks, but how to indicate which events an object can broadcast I've not found any solution.

百度查“android源码分析工具”时发现有一篇知乎文章： 巨人的肩膀 AOSP项目官方: https://source.android.com/source/index.html 这个一定要先读. 项目介绍, 代码下载, 环境搭建, 刷机方法, Eclipse配置都在这里. 这是一切的基础. Android官方Training: https://developer.android.com/training/index.html 这个其实是给App开发者看的. 但是里面也有不少关于系统机制的介绍, 值得细读. 老罗的Android之旅: http://blog.csdn.net/luoshengyang 此老罗非彼老罗. 罗升阳老师的博客非常有营养, 基本可以作为指引你开始阅读AOSP源码的教程. 你可以按照博客的时间顺序一篇篇挑需要的看.但这个系列的博客有些问题: 早期的博客是基于旧版本的Android; 大量的代码流程追踪. 读文章时你一定要清楚你在看的东西在整个系统处于什么样的位置. Innost的专栏: http://blog.csdn.net/innost 邓凡平老师也是为Android大牛, 博客同样很有营养. 但是不像罗升阳老师的那么系统. 更多的是一些技术点的深入探讨. Android Issues: http://code.google.com/p/android

As in title , I try to develop as few schemes for hte 3d graphics enigne -- ogre3d ; problem is the big picture scheme the class Ogre::Root requires quite many arrows descending from it. The model of joining boxes with relational arrows is they can only go in / out by specific points around the border ( called "joints" or something ) . Now, however I wouldn't try there are always 4 + 4 + 3 + 3 joints displaced at four sides , suppose I need to place seven arrows on one side, how do I do that ? EDIT: Here is what I mean, the "flies" or "crosses" to which one can bind the arrows are limited in
