properties can be changed dynamically, but once rewritten, the new function has nothing to do with you, not the same world, the past has been cut off If this is the new object at this point, then the new object's __proto__ is pointing to the new, and the old object is pointing not to the same prototype. It can also be seen that dynamic and rewriting are two unrelated things that cannot be confusedNote the effects of fn.prototype add (attributed to modifications) and overridesAdded: Fn.prototype

Rick Strahl starts his look at web forms and MVC for ASP. net by talking about its strengths. he claims that web forms have been proven to be a very stable and mature platform. even in high performance scenarios, it is rare to have major scalability issues. at the same time, it is really easy to get started. rick continues,

We can see the difference between the two types of functions in service scheduling: Win32 kernel API enters NTDLL through kernel32.dll/advapi32.dll. after the DLL is run, the int 0x2eis used to break the inner core, and the real function call is implemented in ntoskrnl.exe. Win32 user/gdi api directly enters the kernel through user32.dl
Fortunately, the user mode thread should still be safely executed in the system process you selected. If you call exitthread to exit the user code after completing the APC function, the system is likely to be stable.

more like a program than Loader. Then the kernel calls back the HAL OEMInit program. OEMInit is usually written in C. Its job is to initialize all OEM hardware. It mainly includes hooking interrupts, initializing timers, and testing memory.

The system makes some initial configurations for the integrated peripheral devices, and then places them as dumb until their drivers can be loaded. During startup, OEMInit usually draws some flashpoints on the
that dexposed can be used to execute the original function without changing, but some additional processing is performed before and after the original function is executed, such as changing input parameters and return values.
In example2, the original function to be executed can be replaced with a new execution function we need.
Based on the above two implementations, what application scenarios can we derive? Some people say that the specific implementation of the hook api depends on the user'
register for an internal notification from the keyboardnavigation class, used for controlling keyboard focus. an app that creates a large number of these elements can leak weakreference objects and the array space to hold them, even after the elements themselves have been reclaimed. An example: an app that creates a large number of short-lived listboxes will encounter the leak. this can happen in a nested scenario, where an outer ListBox displays a collection that undergoes a large number of a
