Scroll locks can generate scroll locks based on the lock hints specified in the SELECT statement defined in the cursor. The scroll lock is fetched on each line during extraction and is persisted to the next fetch or the cursor is closed, whichever occurs first. The next time the fetch is fetched, the server acquires a scroll lock for the row in the new fetch

The next time the fetch is fetched, the server acquires a scroll lock for the row in the new fetch and releases the scroll lock from the last fetch of the rows. The scroll LOCK is independent of the transaction lock and can be persisted after a commit or rollback operation. If the option to close the cursor at commit is off, the commit statement d

I want to unlock it? You cannot modify the computer's operating system (Windows XP). Because the control is in the CDMA card, you must try to modify the system on the CDMA card through Windows XP, in order to achieve the purpose of unlocking. 2. Some people may ask, what is perfect unlocking? What is not perfect for unlocking now? A perfect unlock is a real unlock. If your iPhone is unlocked perfectly, your iPhone does not need any baseband firmware

This project is a more interesting project source code, can give other items to lock, the principle of the program is a "watchdog" service regularly monitor top-level activity, if the activity corresponding to the package name is locked before the application, then a page will require the input unlock password.
The effect is as follows:

The game engine is one of the most successful applications of finite state machines, because well-designed state machines can be used to replace part of artificial intelligence.AlgorithmTherefore, each role or device in the game may be embedded with a state machine. Consider a simple object such as the gate in RPG games. It has four states: open, closed, locked, and unlocked, as shown in 1.
