{CTRLDOWN} and {CTRLUP}

[PoojaKrishna]

Hi friends,

I'm attaching three scripts here.

Test.exe -> Calls CTRLDOWN.exe and CTRLUP.exe

#RequireAdmin
run("CTRLDOWN.exe")
sleep(500)
run("CTRLUP.exe")

CTRLDOWN.exe -> Sends a {CtrlDOWN} to press CTRL key

#RequireAdmin
Send('{CTRLDOWN}')

CTRLUP.exe -> Sends a {CtrlUP} to release CTRL key

#RequireAdmin
Send('{CTRLUP}')

Test.exe calls two exes to press and release the CTRL keys. Key press is working fine but the release does not work. If I call the CTRLDOWN.exe and CTRLUP.exe, manually one by another or the commands in a single program, it is working fine. Can any one explain what is wrong when I call them from a program?

Thank you so much for being helpful always :-)

@PoojaKrishna
Why don't you use them together, instead of creating three scripts which could be converted in one?

[PoojaKrishna]

My program is a command based one and the parent process writes the commands into the STDIN stream of the child process. On the previous version, the child was closed after executing all the commands but due to some changes in the new version, the child process is closed after executing each command.

I can convert the program into a single one but still was curious to know, what made it not working.

Thank you for your reply @FrancescoDiMuro

Hmmm i've used some console scripts and the child window never closed after a command.

As for the program not working, maybe it's related to the sticky keys, try to make the key up send 2 or 3 times the key up and see if it helps.

Hi PoojaKrishna ,

You know already that in order to disable the effect the pressing of ctrl is needed  when coming  from another user 

so it only makes sense to have the same happening  inside the CTRLUP.au3  script where you must CTRLDOWN again before sending CTRLUP  when coming from another thread

a single thread  cant just CTRLUP if it doesn't recall a CTRLDOWN   

 the script is considered a user by its own , so, if you cant fake a  CTRLUP with your keyboard it wont make much sense to try it with a script  ..

Thank you for your reply but it does not help.

@Deye, Yes, it makes sense. Thank you for explaining.

@Deye is true ... look :

 

Test.exe -> Calls CTRLDOWN.exe and CTRLUP.exe

#RequireAdmin
run("CTRLDOWN.exe")
sleep(500)
run("CTRLUP.exe")

CTRLDOWN.exe -> Sends a {CtrlDOWN} to press CTRL key

#RequireAdmin
Send('{CTRLDOWN}')

CTRLUP.exe -> Sends a {CtrlUP} to release CTRL key

#RequireAdmin
Send('{CTRLDOWN}')
Send('{CTRLUP}')

That should work

Wow!!! It worked as expected. Thank you so much for your help.

Yes, even @Deye explained the reason, I couldn't work out the solution.

To explain with an other way; When a script is starting. If you dont send a CTRLDOWN Autoit will consider there is no reason to CTRLUP. Easy .
