In this way, you can only access member functions and variables through const_cast or lockingptr. The difference between the two methods is that the latter provides sequential methods for implementation, while the former is implemented by converting to volatile. Lockingptr is quite understandable. If you ne
I want to modify the Windows 7 default shortcut keys, such as canceling the operating system shortcut key "Ctr+z", "ctr+x", and so on. I found a lot of software on the Internet is not appropriate, are added shortcut keys. How can i solve this problem?
Most of the shortcut key settings for Windows 7 are stored in the "C:windowssystem32shell32.dll" file. This file cannot be directly modified, you can copy it
(simplified version heuristic evaluation ) .
In view of the complexity of the existing heuristic evaluation process and the high cost of implementation, the improvement and simplification are based on the features of maneuverability, simplicity, convenience and high flexibility. I have innovated a simplified heuristic evaluation method, which is suitable for projects with high degree of importance and urgency.
Based on who-how-what strategy, the heuristic evaluation of Minimalist edition is c

, this is the implementation of dynamic font first step.
In the above code, the "Ctr" two words refer to the font style defined by the. Main_2 class. Of course you can define different font styles in so that the pages are referenced according to different fonts. Like what:

To make the fonts move, we can take advantage of the events of our CSS or let JavaScript raise events.

have discussed the basic rules, we will study the first threat: SQL injection attacks.
◆ Prevent SQL injection attacks
In SQL injection attacks, you can manipulate the form or GET query string to add information to the database query. For example, assume there is a simple login database. Each record in this database has a username field and a password field. Create a logon form to allow users to log on.
