国内外发展状况:交通检测系统是智能交通系统的重要环节,负责采集有关道路交通流量的各种参数。随着视频车辆检测技术的发展 ,人们已不满足于仅仅检测出车辆, 美国联邦公路局进一步利用此技术来提取交通参数,如交通流量,十字路口的车辆转向信息等。国内关于交通视频检测的研究滞后于国外,技术基础较弱,但也有不少公司做出了产品,如清华紫光的视频交通流量检测系统 VS3001,深圳神州交通系统有限公司开发的Video TraceTM,厦门恒深智能软件系统有限公司开发的Head Sun Smart Viewer-II 视频交通检测器等。当然这些产品的功能比较单一,与国外产品相比有一定差距。基于视频图像技术的方法具有直观、可监视范围广、可获取更多种类的交通参数以及费用较低等优点,因而可广泛应用于交叉道口和公路干线的交通监视系统中

1. 使用3个文本框和1个按钮设计一个加法计算器,在文本框中输入两个整数,单击“求和”按钮时,在第三个文本框中显示这两个数据的和。 2. 设计一个JFrame窗口,窗口中心添加一个文本区。另添加2个菜单(文件和帮助),每个菜单包含至少2个菜单项,当选择某个菜单项时,窗口中心的文本区显示相应信息。 3. 利用2的结果,在文件菜单中加入“编辑”菜单项用以打开一个已有的文本文件进行修改。
1 using three text boxes and a button design an addition calculator in the text box, enter the two integers, click the " Sum" button, in the third text box displays both data and. (2) design a JFrame window, the window center to add a text area. Another added two menus (File and Help), each menu contains at least two menu items, when you select a menu item, the window center text area displays the appropriate information. 3 Use the two results in the File menu to add the " Edit" menu item to open an existing text file to be modified.

这是配合笔者发表的系列技术文章《用户控件制作实例与详解(基础篇)》的实例制作。   这个按纽控件有20多种外观形状,标题文本有常规、立体、雕刻、浮雕四种选择,背景色可设置成渐变色或纯色,还可以加载真彩图片。   其中比较特殊的是星形和十字形,例如十字形按纽,你可以在四端再加上四个圆形(用图片框和API函数制作而成),连同控件本身中间的那个圆,就有五个圆形按纽,适于用在播放器上,堪比windows 7按钮。
This series of technical articles published by the author with the instance of the instance of the user control production Xiangjie (The Basics) " production. This button controls 20 different looks in shape, the title text with four options of conventional, three-dimensional, sculpture, relief, and background color can be set into a gradient or solid color, you can also load the true color picture. Special star and cross, for example, the cross-shaped button, you can quadripole plus four round (made with a picture frame and API functions), together with the control itself the middle of that circle, five circular button, suitable for use on the player, comparable to windows 7 button.

Interrupt trigger for 2500, every time the button AN produce a signal interruption. A 8259 issued to the interrupt request signal. If the interrupt source-level signals do not meet requirements on the 7th was interrupted to show that "Err."

[按钮控件] NETTransactions

NET的事务控制 在分布式应用程序中,不可避免地会经常使用到事务控制。事务有一个开头和一个结尾,它们指定了事务的边界,事务在其边界之内可以跨越进程和计算机。事务边界内的所有资源都参与同一个事务。要维护事务边界内资源间的一致性,事务必须具备 ACID 属性,即原子性、一致性、隔离性和持续性。 本地事务和分布式事务 -------------------- 本地事务是其范围为单个可识别事务的数据资源的事务(例如,Microsoft SQL Server 数据库或 MSMQ 消息队列)。例如,当单个数据库系统拥有事务中涉及的所有数据时,就可以遵循 ACID 规则。在 SQL Server 的情况下,由内部事务管理器来实现事务的提交和回滚操作。
NET Services in distributed control applications, will inevitably be used to control affairs. Services have a beginning and an end, they have designated border affairs, in its affairs within the borders across process and computers. Services within the borders of all resources involved with a transaction. Services to protect the resources within the borders of consistency, the Panel must possess ACID properties, that is, atomicity, consistency, isolation and sustainability. Local Affairs and the Distributed Transaction-------------------- domestic affairs of its range of single- Services could be the identification of resources data services (for example, Microsoft SQL Server database or MSMQ Message Queue).
