Programming | server | Web Java Socket API provides a very convenient object interface for network programming. This article uses a simple TCP Echo server as an example to demonstrate how to use Java to complete a network server. The TCP Echo server used by as an example works in the following ways: when a client connects to a server through TCP, the cli

IE web pages are a classic issue in IE programming. After the release of ie9 Beta, I received a lot of questions about this. Recently, I have re-structured the Code related to IE and windows so that ie9 can be perfectly compatible with the original GDI function when hardware acceleration is enabled. While the memory is still fresh, write a summary for your reference. Mainly include the following3Interfaces

, you can use the ASP. NET AJAX loopback. In the Ajax loopback, only JavaScript is used to return and refresh part of the page, which is easy to do with UpdatePanel.The UpdatePanel internally issues a ajaxpost request. Ajaxpost requests that a XMLHttpRequest object be used to send a request to the server. The server returns only the data for the update UI. After explaining the data, the JavaScript code modifies the HTML control inside the UpdatePanel and displays a new UI.Note: 1) You need a Scr

JS Code is often used in Web programming and has powerful functions. The following is the common JS Code in my work, which is summarized as follows: 1. Trigger the event staff to submit the form Example 1: 2. onchange and onclick event triggering Onchange is mostly used in trigger events in the drop-down list, with the focus on "change", that is, trigger events. Such as page Jump. Onclick emphasizes "clic
