The User Information table is available in most systems. We also know that there will usually be a field similar to the registered IP and the last login IP to store the IP address of the user at the time of registration and the IP address of the last login.
Get such an address, in the Background display xxx.xxx.xxx.xxx address section, let people see very unnatural, simply do not know the specific geographical location.
Now we can simply implement this function.

Iterator interface:
So the container class that implements the collection interface has a iterator method to return an object that implements the iterator interface.
The iterator object is called an iterator to facilitate the traversal of elements within a container.
The iterator interface defines the following methods:

Jquery is undoubtedly one of the popular JS development libraries and plays a major role in web development, especially server component development. In addition, during interviews with some companies, I asked about JS
Just ask, have you used jquery? No, it seems that you are inferior. To put it bluntly, you can still learn excellent things, whether it is for the company or not during project creation.
We do not need to use this as a whole. It is worth studying.

The following describes how to create a user control with an event:
Standard web spaces have events for interaction, and user controls also exist.
To create a user control with an event, you only need three steps:
1. Define a public event Delegate, such as clickeventhandler
2. Define the method for triggering the event in the user control class, such as The onclick method.
3. Check whether the event is empty in the method that triggers the event. If not, write the event.Code.

Caching is a technology that stores very time-consuming data in memory and is an important feature of ASP.net. For example, you can cache data that is time-consuming and complex, and subsequent requests need not be fetched from the database and taken directly from the cache. By caching, you can greatly improve the performance of the program.
There are two main types of caching:
1. Output Caching
2. Data caching

In ASP. net1.1, it is very painful to keep the position of the scroll bar after callback, especially when there is a grid in the page and you want to edit a Specific Row. The page is reloaded and must be rolled down at the top of the page to keep the page unchanged. In asp2.0, you only need to simply add the maintainscrollpostiononpostback attribute to the page attribute:
