Please help me to see why global hooks are not easy to use? ? ? ? ? ? ? ? ? ?

It seems that you have not yet understood the definition of global hooks. Global hooks must be made into dlls so that the process can be injected.

Is it a DLL?

Yes, dll

不大不小虾米

I don’t understand. Sorry, the food is dead...
