Learning GoalsThe second chapter is to learn character and string processing, in order to better understand the content of this chapter, I added additional auxiliary content: storage mode (big-endian storage and small-end storage), character encoding scheme (see it). The following are the learning objectives of this chapter:1. Big-endian storage and small-end sto

write:SetHandleInformation(hObj,HANDLE_FLAG_INHERIT,0);The 3.HANDLE_FLAG_PROTECT_FROM_CLOSE flag is to tell the system not to allow the kernel object handle to be closed:SetHandleInformation(hObj,HANDLE_FLAG_PROTECT_FROM_CLOSE,HANDLE_FLAG_PROTECT_FROM_CLOSE);//如果在这个函数之后调用CloseHandle关闭这个句柄就会报错4. If you need to tell the system to allow the kernel object handle to be closed, we can write:SetHandleInformation(hObj,HANDLE_FLAG_PROTECT_FROM_CLOSE,0);//这时候在这个函数调用之后调用CloseHandle函数关闭内核对象句柄不会报错，成功关闭

The 8th chapter is very admire the writing standard person, you must use 5 years for the measurement standard eye to see the question. It takes 5 years to get the things you really want to be useful. This is the case with WebDAV, which is quite comprehensive in Mac, but incomplete in Windows. It also said that 37Signals, a small team focused on AJAX Web applicati

This chapter relates to the source code, and the previous chapter learned git download two sets of source code, a set is the Android source code, all download will nearly 4GB size, its gold content imaginable. The other is The core Linux kernel source code, hundreds of MB after decompression . First we learn to download, compile, and test the Android source code. 1. Configure the Android Source code Downlo

the outside, so the inner table needs a proper index. 5. Associated query optimizerbut inside looks are often not what we can decide,and the MySQL Optimizer will work, and the optimizer will create a depth-first tree, with different combinations to get the least expensive execution plan. However, when the associated table n is too large, the number of stars in the execution plan tree rises exponentially andn exceeds optimizer_search_depth Instead of

Typical users can include: Name, age, income, the proportion and importance of the users on the market, the typical use of the software , the use of the Software/service environment, Life /work status, knowledge level and ability, user motivation, user preferences. 2, the main steps of the function-driven design are:(1) Construction of the overall model (Develop an Overall models);(2) Construction function list (build a Feature list);(3) Development plan (plan by Feature);(4) F

The eighth chapter avoids "empty comparison"Before we deal with the incoming parameters, we definitely need to verify if we want to, that is to say, in most cases, we need to compare the type.The author first gives a code that doesn't seem to feel right: var Controller = { function(items) { ifnull { // bad notation Items.foreach () (function() { // perform

Alloc and new use summary 1. New is seldom used in real-world development, generally creating objects we see all [[ClassName alloc] init] But it doesn't mean you won't be exposed to new, and you'll see [ClassName new] in some code,There is also the possibility of being asked this question when you go to an interview. 2. So, what's the difference between them? We look at the source:-------------------------------------------
