programmers to directly operate on it.We use the CS register as an example. The same is true for other registers:In realIn mode, when we execute a command to load the CS register (JMP, call, RET, etc.), the relevant values will be loaded into the visible part of the CS register, however, the CPUSee the content in the section to set the invisible part. For example, Run "ljmp x1234, $ go"Then, the visible part of the CS register is 1234 h, and the invi

Introduction:
API Interception is not a new technology. Many commercial software use this technology. There are two methods to intercept Windows API functions. The first one is Mr. jeffrey Richter's module input section for modifying the EXE file. This method is safe, but complicated. In addition, some EXE files do not have a list of DLL input symbols, blocking may fail. The second method is the commonly used jmp xxx method. Although it is very old,
principle of word extraction.First, let me explain the hook problem. The hook is indeed used in the word overlord, and he uses two types of hooks, one of which is the Windows Standard hook. He uses setjavaswhook to install a callback function, which installs a mouse hook, it is used to respond to the mouse message in a timely manner and does not have much to do with word retrieval.Another type of Hook is API hook, which is the core technology of word retrieval. He wrote a
determined that the content of the hidden part is consistent with the content of the segment descriptor (see the format of the segment description ), however, the format may be different. But the format is not important for us to understand this, because it is impossible for programmers to directly operate on it.
We use the CS register as an example. The same is true for other registers:
In real mode, when we execute a command to load the CS register (JMP
function.2. About the jump statement in the assembler, why use jump, about the return value of the study (1), the return value of one, jump directly to the next instruction? (2), how is the return value handled when it is multiple?We write the following procedure:We see how it is implemented in debug as follows:As we can see, when the F function returns, after the function return (after putting the return value in Ax), the next sentence is jmp 020f.
In Pmtest4, we have seen how to transfer from a low privilege level to a highly privileged level for non-conformance code. But how do we move from a high-privileged level to a low-privileged level? At first we were in real mode, the ring 0, how we went from ring 0 to Ring3, which is not possible through call and jmp, and how we should do it. This article is mainly for you to answer these questions, showing the way to achieve this level of privilege tr
of the parameters are consistent with what was described earlier, what is called deep copy, and we look at an example:var result=$.extend (True, {}, {Name: "John", Location: {City: "Boston", County: "USA"}}, We can see that the nested SRC1 in the location:{city: "Boston"},SRC2 also nested the object location:{state: "MA"}, the first deep copy parameter is true, then the result of the merge is:Re
.
$. Extend ($. net, {hello: function () {alert ('hello') ;}}) This is to extend the hello Method to the expanded Jquery net namespace.
III. The extend method of Jquery also has an overload prototype:
Extend (boolean, dest, src1, src2, src3 ...)
The first parameter 'boolean' indicates whether to perform a deep copy. The other parameters are the same as described above. What is "Deep copy"? Let's look at an example:
Var result = $. extend (true, {}, {name: "John", location: {city: "
Do PHP inevitably touch js, I also like this, when using AJAX, I am more accustomed to using $.ajax ({}), this way, because of the strong general. Sometimes less use JS, after a period of time to use, some of the details are easy to obscure, this time, I forgot more parameters when the format of the data, so Baidu search, found:jquery手册描述:data sent to the server. is automatically converted to the request string format. The GET request will be appended to the URL. View the ProcessData option desc

var result=$.extend( true, {}, { name: "John", location: {city: "Boston",county:"USA"} }, { last: "Resig", location: {state: "MA",county:"China"} } );
We can see that the child Object location: {city: "Boston"} is embedded in src1, and the sub-Object location: {state: "MA"} is also nested

(prefix in a) {buildParams (prefix, a [prefix], traditional, add );}}
Now, I understand. If it is json data, we can concatenate strings using their name attribute and value Attribute in one loop.
For a common object, loop through the attributes of the object and splice the string.
Summary:
Therefore, in this article, three types of data can be imported into the ajax function of jquery.
1. Text: "uname = alice mobileept = 110 birthday ="
2. json object: {uanme: 'vic ', mobileIpt: '000000', bi

The Code is as follows:
