Description: Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded and installed the ADOCE SDK from Microsoft, you are ready to use it in your Windows CE Database applications. The sample that I have provided is a *very* simple one illustrating how to instantiate the proper COM objects, and the basics of how to interface with them (in a very simple example) Platform: |

Description: ASP.NET与数据库编程
1.在本实例中，使用的是SQL Server 2000的数据库而这里只给了对应的Access数据库，如果你想在你的机器上在运行程序需要在SQL Server下重新建立一样的数据库，或者使用前面介绍的导入导出工具将.mdb数据库转化为SQLServer数据库。
确保你的机器上的服务名，和程序中的代码要统一。
2.将library文件夹复制到C:\\Inetpub\\wwwroot\\目录下(一般情况是这样），即可运行程序
3.运行ASP.NET程序先要保证您的机器上正确的建立了一个站点，然后将这里的程序考入站点目录下即可。首页为WebForm1.aspx
-ASP.NET programming with a database. In this example, the use of the SQL Server 2000 database here only to the corresponding Access database, if you want your machines running the program in SQL Server under the re-establishment of the same database, or use the above-described I. income derived tools. mdb database into a SQL Server database. Make sure your machine from the services, and procedures necessary to unify the code. 2. Library folder will be copied to C : \\ Inetpub \\ wwwroot \\ directory (this is the general), can run programs 3. Running ASP.NET procedures must ensure that your machine correct establishment of a site and then went to the procedures here directory site can be . Home for the WebForm1.aspx Platform: |

Description: 程序说明：
Form1.cs是应用聚类算法DBSCAN (Density-Based Spatical Clustering of Application with Noise)的示例，可以通过两个参数EPS和MinPts调节聚类。
DBSCAN.cs是实现文件，聚类算法的进一步信息请参考“数据挖掘”或者相关书籍
聚类示例数据来自于sxdb.mdb，一个Access数据库。
已知问题及进一步改进建议：
问题：dbscan.cs行64，SortedList不支持重复键，因此若两个数据点距离相同则无法加入集合
解决：采用人为减小一个微小量，使数据点距离不同且不影响聚类结果
上一解决方案的问题：减小double.Epsilon微小量无助于使SortedList认为两点距离以及不同
解决：采用一个指数增长的微小量，连续重试直至SortedList认为距离已经不同
进一步改进建议：可能通过double的强制转型为内存中的byte类型（假设double型转为8个byte）
然后最后一个byte减去0x01可比较漂亮的解决问题，但是……呵呵，C#中我不会这个操作
也可以自己实现一个SortedList，支持重复键，当然，这，好像是微软应该做的工作了 ^_^

Description: 下面以Access数据库为例说明，用C#的DataSet类访问数据库的一些操作方法。操作涉及的主要C#类有：DataSet：对应数据库表的一个集合，实际上是数据库表在内存中的一个缓存DataTable：对应数据库表，是数据库表行的集合DataRow：对应数据库表行
OleDbConnection：建立数据库连接OleDbDataAdapter：由数据库生成DataSet,并负责DataSet与数据库的同步OleDbCommandBuilder：生成更新数据库所需的指令DataSet、DataTable、DataRow用于数据在缓存中的操作，这上面的操作只有更新到数据库中，修改结果才会被永久保存。OleDbConnection 是用OLEDB方法连接数据库所必需的。-The following Access database, for example, methods of operation to access the database with C# DataSet class. Operation involves the main C#
Class: DataSet: corresponds to a collection of database tables, is actually a database table in memory, a cache a DataTable:
The corresponding database table, database table rows collection of a DataRow: the corresponding database table row
The OleDbConnection: to establish a database connection the OleDbDataAdapter: generate a DataSet from the database, and is responsible for the DataSet
The OleDbCommandBuilder of database synchronization: generate the instructions required to update the database a DataSet, DataTable, a DataRow
For the operation of the data in the cache, the above operation only updates to the database, modify the results will be permanently saved.
