 Posted: Thu Apr 04, 2019 9:58 am Post subject: Check/Toggle hotkey script |
 |
|
32 Bit version (64 should be easy to done).
| Code: | | call _GetAsyncKeyState(VK) |
with a given virtual key, sets eax to 0 or 1 (where 1 is pressed);
| Code: | | call _ToggleHotkey(VK,VaribleADDR) |
with given virtualkey and some address to change state (0 to 1 or 1 to 0);
It saves last call status in _GetAsyncKeyStack
I use this for either applying actions when key is down (_GetAsyncKeyState),
or to apply everytime key state has changed.
Don't forget to backup registers and flags (pushfd pushad, popad popfd)
| Code: | globalalloc(_GetAsyncKeyStack,255) // hotkey toggle memory stack (Up and down states)

label(_ToggleHotkey)
