Source: csdn Author: xstringI don't know what you started to understand hook, I have read Jeffrey Richter's "Windows Advanced Programming Guide" (the new Chinese version is translated as "Windows core programming"). In this book, the author introduces three methods to inject code into other processes, one of which is the global message hook. I first learned about global hooks from this book.We should all kn

Detailed descriptions of hook methods in Ruby This article mainly introduces the detailed explanation of the hook method in Ruby.

-- Hooks are an important part of the message processing mechanism in windows.

"relative position" rather than "absolute position" (how can the two convert in directinput, I didn't try it out). I still had to use: getcursorpos in Win32; second, I could only judge that the mouse was "clicked" and the mouse was not recognized as "lifted, I simulated a "lift" Event 2 ms after the click delay, but this is not the real behavior of the user in the operation;③ Continue with the low-level mouse HOOK: wh_mouse_ll is used, and the corres

After two weeks of hard work, ssdt Hook was finally successful. Here, I would like to thank a great god in the forum. Thank you very much. What is his ID, after adding his friends, I remember the words Lenin under his name. It's a very interesting name. If you want to add a name, you can read my post. There are still a lot of top-level figures in the forum. We cannot use the level to measure a person's knowledge level, just as I saw a post about eager

Tip: If you want to set a system-level Hook, the hook function must be in the DLL. Setwindowshookex (idhook: integer; {hook type} lpfn: tfnhookproc; {function pointer} hmod: hinst; {module (exe, DLL) handle containing hook functions; generally hinstance; for the current thread, it can be 0} dwthreadid: DWORD {

C ++ system hook application implementation steps Recently, I learned c ++ Hook Functions and got a lot of help from my friends. Especially bdmh, daniel is very grateful.I deeply feel that on the way to learning c ++, I have many confidants. I am not fighting alone.Combined with custom message ing, This is a summary of learning.Step 1: Create a win32 dynamic link library (an empty project DLL) and name it H

GoalThe thing to do, is when the file is submitted to SVN, you can re-read the server to all the content of the commit file, and according to some rules to verify the legitimacy of the file, if the validation fails, the submission is terminated, and the SVN client displays an error message.Preparatory work1, install SVN server, this example uses COLLABNETSUBVERSION-SERVER-1.6.3-3.WIN32, the installation using the default repository directory, that is, c:/svn_repository. 2, create an SVN reposito

How much is your direction worth? Looking at the current "it market" from the data of pull-hook netPrefacehave been said to analyze the data on the hook network to learn the crawler, the process of learning reptiles is very interesting, wrote a lot of gadgets also encountered a lot of problems, the learning process recorded in the blog, but also accidentally made a point of click. (Seems a little off-topic,

When writing a hook, I put the hook uninstallation function in dll_prcess_detach. What then happens? Is to open an applicationProgramThe hook can be executed normally. However, after the program is closed, the hook (Global hook) has no effect on any other program. Obviously

What's the hook, what's his role? You know that almost all of the PHP video lectures, including books, there is no mention of the concept of hooks, but found that the actual project is often used, so sometimes feel that the practice of teaching the disconnection has been the biggest fault of the Chinese, useless talk and surging water, continuous, and the use of no mention. After complaining to face the grim reality, then the question came, in the end

Before the hook or a bit of interest, write down the previous design pattern, look at the hook, in fact, you can look at the comparison.Hooks are very relevant to the observer pattern or strategy pattern in my previous article, and should be interlinked.Application scenario: The text---of the TP behavior Framework, such as route detection is a behavior, static caching is a behavior, user rights detection is

First look at the x86 under the hook.1. The principle is to find the address you want to hook.2. Save the original data for this address. (This saves at least 5 bytes of data because a call instruction is 5 bytes3. Change this address to call 0Xxxxx (5 bytes) that corresponds to opcode for E9 0Xxxxx after four bytes for a function address4. Fill the 0XXXXX formula for its own function address-current addres

in a report project, data calculation methods for some reports change frequently. For example, the real wages of an enterprise employee are calculated by the performance score, the algorithm changes frequently, and the old algorithm needs to be replaced with the new algorithm without altering the other code. If the computation is implemented in Java, it is possible to implement dynamic hook-up calculation module, but there are some problems such as la

This beginning, I began to explain the whole process of my interface development, step-by-step explanation of the development of the interface process, this article is mainly about hook programming, hook all the forms.

The concept of "hook" is not really familiar with, recently saw a PHP framework used in this mechanism to extend the project, so probably to understand the next.The basic idea of hook plug-in mechanism:In the project code, you think that you want to extend (temporarily not extend) place a hook function, and so on need to extend the time, the need to implement the

Although there are not many hook functions, their parameters are complex. You should start with the parameters before proceeding. Unhookwindowshookex only needs the hook handle returned by setwindowshookex as the parameter, which is simple; Let's take a look at the setwindowshookex statement: Setwindowshookex (idhook: integer; {hook type} lpfn: tfnhookpro
