The Windows system is based on the event-driven mechanism. To put it bluntly, the entire system is implemented through message transmission. Hooks are very important system interfaces in Windows systems. They can be used to intercept and process messages sent to other applications to implement functions that are hard to implement in common applications. Hooks can monitor various event messages in the system or process, intercept messages sent to the target window, and handle them. In this way, w

The basic concept hook (hook) is a platform for Windows Messaging mechanisms where applications can set up a subroutine to monitor certain messages in a specified window, and the monitored windows can be created by other processes. When the message arrives, it is processed before the target window processes the function. The hook mechanism allows the application

From now on, we will introduce 15 types of all hook types. Since I am using C # Now, it is more accurate to translate all functions in the original text into "methods" and actually translate them into "functions. In the original text, "callback function" is translated as "callback function ". Each type of hook enables an application to monitor a different aspect of the system's message-handling mechanic

Basic ConceptsHook is a platform for message processing in windows. Applications can set sub-processes on the platform to monitor messages in a specified window, the monitored window can be created by other processes. When a message arrives, process it before the target window processing function. The hook mechanism allows applications to intercept and process window messages or specific events. A hook is a

Windows hook functions can be considered as one of the main features of windows. They allow you to capture events that occur in your own processes or other processes. With "hook-up", you can give Windows a callback function to process or filter events. This function is also called "hook function". When an event you are interested in occurs, windows will call this
