★3. Use session VariablesPresumably, this is definitely the most common usage. Its operations are similar to those of the application, which act on individual users. Therefore, excessive storage will result in the depletion of server memory resources.A. aspx C # codePrivate void button#click (Object sender, system. eventargs E){Session ["name"] = label. text;}

Security Description: user input on ASP. NET may include malicious client scripts. By default, this page verifies that user input does not include script or HTML elements.
If the verification control cannot parse the values in another control, they usually do not cause errors. Instead,
You can verify user input against the database to ensure that user input values are identifiable. To do this, you must write code in the customvalidator control to find data matching items in the database.
1. Add the customvalidator control to the page and set the following attributes:

This solution won't support an existing ASP application which stores a COM object in the Session object. In this case, a custom marshaler are needed to serialize/deserialize of the States in order to use the custom session object. In addition, this sol

Database Access Performance optimization Connection and shutdown of the databaseAccessing a database resource requires creating a connection, opening a connection, and closing the connection several operations. These processes need to exchange information with the database multiple times to pass authentication, which consumes server resources more often. Asp. NET provides connection pooling (Connection

The purpose of this article is to provide a feasible solution to integrate and manage existing ASP Program To ASP. NET. This application solves The solution tries its best to update the current session in the ASP Web server memory to ASP.
Now some. NET developers began to discard the asp.net built-in caching mechanism, instead using memcached--, a distributed memory caching system, originally developed by Danga Interactive for the LiveJournal site.
A fundamental problem with caching is how to handle obsolete data. When running on a separate Web server, you can easily clear a cache that has been confirmed to have been changed. Unfortunately, ASP

All tests are run on the same machine (Toshiba Tecra M5 with 4G RAM and 60G 7200-turn drives).
The Ubuntu 9 and Windows Server 2008 Standard editions are installed on separate (but identical) hard drives.
Linux uses Apache2,windows to use IIS 7 as its own Web server.

Comparing the two development tools alone makes no sense. Because the two have their own strengths in their own development fields, it is like comparing Java with. NET, each having its own advantages. The main purpose of this article is to compare ASP. NET and PHP, so that you can better understand the differences between the two, so that you can choose your own

Third, to connect flash to external data there are three ways to integrate Flash animation with external data: Flashvars,loadvars and new flashremoting technology. One of the easiest ways to do this is to pass the variables in the HTML part of the code by using Flashvars to deliver the external data from an. aspx page to a flash animation embedded in a Web page. These variable values set with Flashvars can be accessed at the root level of the Flash animat
