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.
Hook, for most programmers, the word is not unfamiliar. For Windows systems, message messages are passed through the entire system, which is simp
I recently studied how to use HOOK to intercept messages from other applications, so I wrote a HOOK program to HOOK up the most commonly used communication tool.MSNAlthough there is no practical significance, as a learning study, it can help us understand how to use HOOK to inject your own DLL into an existing program

How does PHP implement the hook mechanism? This paper mainly introduces how to implement hook mechanism in PHP, introduces the principle and realization process of hook mechanism in detail, has certain reference value, and is interested to understand. We hope to help you.

The behavior extension previously written to TP3.1 is tag (), and another argument is introduced in TP3.2-: hooks.
Let's take a look at the hooks in TP3.2:
One: File flow:
1:/index.php->require './thinkphp/thinkphp.php ';
2:/thinkphp/thinkphp.php-->require Core_path. EXT; Think\think::start ();
3:/thinkphp/library/think/think.class.php-–>app::run ();
4:/thinkphp/library/think/app.class.php. Here the basic flow is finished, (here do not say details);

Code review not only improves the quality, but also provides an excellent means of knowledge sharing and guidance.
Code review generally has two forms: Pre-commit-Review and post-commit-review.
Pre-commit-review refers to the Code submitted to the code library.BeforeCode review;
Post-commit-review refers to the Code submitted to the code library.AfterPerform code review.
Reviewboard is an open-source Web-based code review tool that supports subversion, CVS, git, and mercurial version contr
The SVN hook mechanism allows you to customize some operations based on SVN actions. Post-commithook is a user-defined operation performed after the user executes commit. For example, after the user commit, the user automatically calls the post-commit hook script group to send an email to the project team. The implementation process is to automatically call post-commithook after commit to send emails.
