add a socket to directly access the memcache interface function, in this way, the memcache extension class does not need to be installed in the PHP environment. This effectively avoids the misoperation of flush, and after the cache mechanism such as apc is added, socket access to the memcache interface is not much slower than expansion.In addition, the MyCache class has an additional function: When the memcache service fails, the MyCache class simply returns a null value without directly making

In the on event handler function action attached to the button, this refers to the timeline that contains the button. Example 1-1: Put a button on the stage. Define a variable var i:number=0 on the timeline, and enter the following statement on the button
On (Press) {
The result of the trace (this)//output will be _level0, which means that this is the reference to the root timeline
Trace (THIS.I)//output will be 0
Instance 1-2: Put an

In -Wl,--wrap,malloc the role of coming here again, so opened the "chicken eggs, eggs and chickens" in the death cycle, until--stack overflow.Therefore, in this function can use only the stack space or global space, if you must use heap space, also must be shown to use instead of __real_malloc new or malloc. Because of the inevitable use of dynamic memory space in map, hash, or discard it.What do we do? To avoid complications, I used the simplest but somewhat stupid method-arrays.struct memory
model. Volcano Personal Portal V3 main station, because the background picture size is too large, I used this mode, according to most people, the user experience is very good:
In short, the three models can be said to have advantages and disadvantages, how to choose or to be based on specific project decisions, of course, team and individual capacity is also an important factor. In general, programmers are likely to prefer flash mode; traditional web designers tend to prefer PS mode; the guys w
We recommend that you first download the original file and open it so that you can refer to the following descriptions.1. we need to use a button to drag the text, so we need to have a text mc (mc refers to video editing), write a text in the scene, select a text, press F8 to convert it into mc, mc is named as a public

This effect is very common, in fact, the implementation is relatively simple, mainly through the control of the MC x coordinates to achieve.Create a new MC, nam

Using for is an important means of optimizing as. If we want to 20 MC implementation in response to mouse click events, if not for the direct write then need dozens of or hundreds of lines, and for only a few lines to use.

113. Q: How does FLASH connect to the background? [Source code]A: Use the sendAndLoad () method of the LoadVars () object to send and receive data. 114. Q: How can I pause or play a sound?A: When running the stop () command, you can use the position attribute of the sound object to obtain the playback time (in milliseconds) of the current sound file, and then use start (time, loop) play the video at the current position. 115. Q: How do I define a two-dimensional array?A: The following defines a

tell me gotoAndPlay (1)
So the 1 inside is the parameter of this function of course, besides this parameter, do you know gotoAndPlay () other parameters?
You'll answer I have such as gotoAndPlay ("XX frame label") gotoAndPlay ("xx scene")
Because of these parameters, this function is the external interface we only know gotoAndPlay (10) The timeline jumps 10 frames to play
and gotoAndPlay () How it works inside, we don't need to know,
As long as we know what the interface is and what we can do w
For an object type, when declaring a property, the attribute's attribute is set to retain or copy, which is different from setting it to assign.The following is an example of the Student class and the MyClass (Class) class to illustrate why you want to set to retain or copy.Student class@interface** sex; -(ID) Initwithname: (NSString *) name *) sex; -(void) sayhi; @endNow declare a MyClass class with a property of type Student and now set it to assign.@class Student; @interface *

The principle of Memche Message Queuing is to make a fuss over the key to do a continuous number plus the prefix records after serialization of messages or logs. The content is then landed in a file or database through a timer program.
The use of PHP to implement Message Queuing, such as sending a large number of emails to send a time-consuming problem, you can take the queue.Lightweight queuing servers for easy implementation of queues are:Starling lightweight persistent servers that support t
Data caching
Here is the data cache refers to the database query cache, each visit to the page, will first detect the corresponding cache data exists, if not, connect the database, get the data, and the query results serialized after saving to the file, the same query results are obtained directly from the cached file.
The code is as follows
