ATL Currently, MFC and ATL represent two frameworks for different types of Windows-based development. MFC represents a simple and consistent method for creating an independent windows application. ATL provides a framework to implement the sample file code required to create a COM Client and a server. ATL is differ

When you use ATL technology to do projects, must have found a very troublesome string character set problem, the following list of common points and key records for future reference.ATL provides a number of string conversion functions, and if the compilation option makes the source and destination character types the same, then these classes do not perform any conversions, as described in the article on setting up system compilation items before Windo

called "garbage Collector", as the name implies is the garbage collector, then only the object called garbage can be recycled by GC. That is, the memory used by a reference type object needs to be reclaimed by GC and needs to be garbage first. So. NET how to determine a reference type object is garbage,. NET's judgment is simple, as long as the object or its contained sub-object is determined that no reference is valid, then the system considers it to be garbage.With these two basic concepts in

T His code creates is only one object, the StringBuffer , at location 0.In conclusion, StringBuffer concatenation is significantly faster than String concatenation. Obviously, StringBuffer s should is used in this type of operation when possible. If String the functionality of the class is desired, consider using a for concatenation and then StringBuffer performing one conver Sion to String .Reggie Hutcherson is a Sun technology e

implemented according to the callback function on each FD, only the active socket will actively invoke callback, so in the case of less active sockets, using Epoll does not have a performance problem with the linear descent of the preceding two. However, when all sockets are active, there may be performance issues. 3.

Java-to-business versus PHP-to-business comparison

to reduce space usage is to take the field names as short as possible, so that space is small, but this requires a tradeoff between legibility and space occupancy. I have suggested that the author put the field name index, each of the field names in one byte, so you don't have to worry about how long the field name takes. But the author's concern is not unreasonable, this index method needs to be a result of each query to replace the index value with the original value, and then send to the cli

For example, this lambda captures the Variablex:int x = 5; return y x + y;In order for this lambda declaration to is valid, the variables it captures must be "effectively final".

Row versus set processing, surprise!Craig shallahamer: 1. set Based processing will likely be much faster than row based processing. our experiment of processing 100 k rows showed row based processing was 3700 times slower than set based processing. not twice as slower or even 10 times slower... 3700 times slower! (The difference is 3700 times) 2. compared to set based processing, row based processing times degrade much quicker than set ba
