Summary: hooks can monitor various event messages in a system or process. Intercepts messages destined for the target form and processes them. This allows us to install our own defined hooks in the system to monitor the occurrence of specific events in the system. Completion of specific functions, such as the interception of keyboard, mouse input. screen fetching words, log monitoring and so on. The following shows how to install an in-process

HOOK is a platform for message processing in Windows. Applications can set sub-programs to monitor certain messages or specific events (such as keyboard and mouse events) 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 applic

There are bugs in the original, because this is the code I converted from C #, where the original conversion was not fully compatible because of the different nature of the two languages. Of course, now I am fully capable of compatible with the characteristics of both languages, so rewrite this code, the original code in the event detection, as well as the original code in the KeyPress time can not detect input character casing bug elimination (thanks to Comrade Verywzm). Note: If this code wa

In order to monitor various event messages in the system in applications, indow's Message Processing Mechanism provides various callback functions. This hook function is similar to extending the interrupt driver. Multiple reverse functions can be attached to the hook to form a function chain. Messages generated by the system are first sent to various hook functio

Some time ago I have written a "use of the underlying keyboard hook screen any button", and put it on my blog. The title of this article has changed "shielding" to "intercept", which is obviously stronger than the previous version. For the DLL that was written previously, there's a less-than-ideal place where you can only mask. If you want to add some "little gestures" before masking, you can only modify DL
