每一个参加排列的数据对应二叉树的一个结点，且任一结点如果有左（右）子树，则左（右）子树各结点的数据必须小（大）于该结点的数据。中序遍历排序二叉树即得排序结果。-Order to participate in each of the data corresponding to a binary tree node, and any one node if there is left (right) subtree, then the left (right) subtree of the data node must be small (large) in the node data. Order traversal of binary tree that is the result of a sort.

重写了微软提供SQLHelper(共用的数据库调用接口） 1把SqlHelper的connectionString做成一个全局量，统一设置数据库连接字符串 2增加了返回特定表名的DataSet的各接口。 可在项目的config文件设置数据库连接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] 当然可以把数据库连接方法修改后直接用。-rewritten Microsoft SQLHelper (shared database Call Interface) a SqlHelper the connectionString caused an overall volume, uniform database connections increased by two strings to the specific name of the table in the DataSet interface. In the config files set database connection string private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings [ "ConnectionString"] lt; !-- Application specific settings-- gt; Lt; AppSettingsgt; Lt; Add key

一个二叉树的三叉链表运用实例，求出叶子的结点并输出从根结点到该叶子结点的路径!-a binary tree using the trigeminal Chain example, the leaves are obtained and the output node from the Root of leaf nodes in the path!

录入数据是开发数据库管理软件最基本的工作,录入数据有多种方法,本方法通过药品库入库登记来说明利用表格录入数据的方法.单击登记按纽,选择"供应商"全称,经手人,结算方式"等信息,在表格中输入入库药品的信息,在药品编号列选择药品编号后回车,将自动填入该药品的基本信息,用户在最后一列回车后自动添加新的记录.-development of the database is the most basic management software, a data input methods, the method for warehousing drugs through registration forms to illustrate the use of data input methods. Click registration button, select the "supplier" designation, handling, clearing way "information, etc. input forms in the arsenal of drugs, the drugs listed No. No. choice after the transport drugs, will automatically fill in the basic information of drug users in the final after a carriage return automatically add new records.
