In order to improve the refresh efficiency of tree control, local refresh technique is used.The. aspx code is as follows:Onselectednodechanged= "tv_china_selectednodechanged" expanddepth= "0" >Id= "ScriptManager1" runat= "Server" >Text:Value:Valuepath: Observe the change of time within two controls to see the effect of local refresh.The. Aspx.cs code is as follows:Using system;using system.collections.generic;using system.linq;using system.web;using System.Web.UI;using System.web.ui.webcontrols;
This article is a paper note for reference [1].convolutional Neural Network has a good performance in all tasks of supervised learning, but it is less in unsupervised learning field.

Establish a connection
1)
Define a connection object and instantiate it through new
2)
Assign values to the connection string commmandstring
3)
Call the open method of the connection to establish a connection.
4)
When no connection is used, call the close method to close the connection.

By default, a row of data is locked each time. The atomic operation is performed when the row data is written. However, the row data can be locked and then read and write at the same time.
We can also lock Multiple rows of data at a time, but this operation requires us to actually specify it.
Conceptual Model
Conceptually, a table consists of multiple data rows, and columns in each data row do not necessarily
When using ASP to manipulate the database, many people use the recordset, but I feel better with the SQL statement, so I wrote this article, I hope it will help you.

Therefore, to conserve server resources, the connection should be shut down as much as possible to free up resources for the connection, and the technique of shutting down the recordset without closing the recordset is called a disconnected recordset, which itself is called a disconnected recordset.
Here's an example of how this technique is used (Northwind.mdb is a database from Microsoft Access97, file Adovbs.inc can be C:\Program Files\Common Files\ System\ado found below):
