Issue with Send("{SHIFTDOWN}")

[PoojaKrishna]

Hi friends,

I'm trying to send SHIFTDOWN, to keep the Shift key pressed until I close the program or releases the key.

Send ( "{SHIFTDOWN}")
sleep(100)
$text = InputBox("Shift key down", "Shift key is down. Type something: ")
$ret = Msgbox(0,"", "Press and release shift key manually and select [Ok] to continue")
$text = InputBox("Shift key up", "Shift key is released manually, now type something: ")
Send ( "{SHIFTDOWN}")
sleep(100)
$text = InputBox("Shift key down Agin", "Shift key is pressed again, now type something: ")

In the above program sequence,

1. Send SHIFTDOWN from program, Works as we type in the text are in Capital letters

2. Manually presses and releases the SHIFT button. SHIFT key is released as when we type, text is in small letters only.

3. Again send SHIFTDOWN from program, but not working. When we type the letters are in small letters.

 

If we send a SHIFTUP  before  sending the SHIFTDOWN again, then it is working correctly and the text appears in capital letters only. Can any one explain why this happens?

Send ( "{SHIFTDOWN}")
sleep(100)
$text = InputBox("Shift key down", "Shift key is down. Type something: ")
$ret = Msgbox(0,"", "Press and release shift key and select [Ok] to continue")
$text = InputBox("Shift key up", "Shift key is released manually, now type something: ")
Send ( "{SHIFTUP}")
sleep(100)
Send ( "{SHIFTDOWN}")
sleep(100)
$text = InputBox("Shift key down", "Shift key is pressed, now type something: ")

 

Thank you.

It works as supposed to do:

{SHIFTDOWN}

Holds the SHIFT key down until {SHIFTUP} is sent

https://www.autoitscript.com/autoit3/docs/appendix/SendKeys.htm

So, look like that combination of manually and automated SHIFT key pressing wasn't considered.

Yes but still, why is it not working after a manual shift press and release?

Only want to see, if there is a better solution than I applied now. Now, in my code, to make {SHIFTDOWN} to work always, I am calling a {SHIFTUP} before it.

Thank you.

Look at controlsend. It is MUCH more stable. Right now if your window loses focus - your script will break.

[PoojaKrishna]

Thank you for your suggestion Bert but when I execute the script, I do not know the control. I'm trying to type in some previously saved  text and control keys to the active control on the active window.

Is there any issue in calling a {SHIFTUP} always before calling a {SHIFTDOWN}?

there might be issues because when you send SHIFTDOWN its leaks to what ever is open
make sure to send SHIFTUP especially before you exit the script otherwise it will continue to linger, manually needing to press shift to release its effect

have you tried to get the control ID using the AutoIt Info tool?

[PoojaKrishna]

Yes, but the controls are not readable.
