简要说明:直接通过DAO读、写Access文件 　　 直接利用DAO来创建、读写Access文件，总的说来，对比上篇<直接通过ODBC读、写Excel文件>来讲，要简单一些。在下面的示例中，我们将用到两种方法：SQL和DAO类涵数来混合实现它们，这样做的目地，我想可以使大家更加方便灵活的运用它们来完成你想要做的东西。在示例程序中默认指定创建数据库名为：Demo.mdb，内部表名为：DemoTable，写入两个字段：名字和年龄，采用和上一篇读写Excel类似的操作，你也可以根据自己需要来动态改变它们。 (Brief Description : DAO directly through reading, writing documents directly using Access to create DAO, Access document literacy, in general, compared to the previous chapter)

Simple Windows Services Describe Windows Service under Visual Studio Introduction As a matter of fact Microsoft Windows services, formerly known as NT services enable you to create long-running executable applications that run in its own Windows session, which then has the ability to start automatically when the computer boots and also can be manually paused, stopped or even restarted. This makes services ideal for use on a server or whenever you need long-running functionality that does not interfere with other users who are working on the same computer. You can also run services in the security context of a specific user account that is different from the logged-on user or the default computer account. Windows services don抰 have any interface to the user, so it can not be debugged like any regular application, but it抯 debugged as a process. .NET has a very nice tool that enables processes debugging while it抯 in the run status, by easily pressing Ctrl + Alt + P shortcut.
