Question on KeysDown ()

[penopia]

The Livecode Dictionary says "The keysDown function returns empty if no keys are being pressed." But keysDown() function always returns "255" even I don't press any key. Anyone can explain this to me ? Thanks

Hi,

Which version of LiveCode do you use? Check your keyboard. Do you have any devices connected to USB, bluetooth or serial port for instance, which might cause this?

If I execute the syntax

Code: Select all

put the keysDown

in the message box, I get 65293, which is as expected, because that's the number of the return key.

Kind regards,

Mark

Hi.

Try this in a button:

Code: Select all

on mouseUp
   put random(99)
   wait 25
   put keysDown()
end mouseUp

You should always get a number, and then empty.

I can't duplicated the problem in this computer, itls going well.
I'm going to check again my home computer again.
I checked all the number returned form keysDown function.
Where the number "255" comes from ?? ....

Thanks again.
