c# - Send virtual mouse clicks that are ignored by GetAsyncKeyState()? -

i've been experimenting , searching day, , can't life figure out how this.

as title reads, want able send mouse clicks ignored getasynckeystate().

basically i'm doing:

//while physically holding left mouse button... while (getasynckeystate(0x01) != 0) { //left mouse button virtually downwards (obviously downwards first loop) mouse_event(2, 0, 0, 0, 0); thread.sleep(100); //left mouse button virtually mouse_event(4, 0, 0, 0, 0); }

now, while-loop stops because virtually lift button, i'm asking alternative mouse_event/getasynckeystate (or parameter don't know about), can manipulate key states without affecting actual state.

for example, i've been able in autohotkey using send {lbutton up} , getkeystate("lbutton", "p").

any ideas?

msllhookstruct contains llmhf_injected , llmhf_lower_il_injected flags. maybe should take @ it.

the code below empty form timer, configured "on" , phone call "timerontick" every seconds.

when click, output "497, 361, 0" when timer click output "497, 361, 1"
