Buonasera Lestroso,

what exactly do you mean with "open and close a cd"?

To "open" a card you need to "go to cd xyz" and to "close" it you need to go to another card or close the stack. Is that what you are looking for? Of course this can be scripted.

Something like this?

Code: Select all

on rawKeyDown pKey
   --F1
   if pKey is "65470" then
   go to next card
   --or go to card "card name"
   else
      pass rawKeyDown
   end if
end rawKeyDown

I believe he means a 'cd/dvd player', not a cd(card). I could be wrong though.

I believe what you are going to wind up using is "shell" function, probably within an if/then or case/switch statement (since you'll have to issue different command line functions based on windows/mac), but maybe someone else has actually played with ejecting cds/dvds and will know better.

AHA!

OK, on the Mac you can use shell to open and close the CD try:

Code: Select all

...
## Open:
get shell("drutil tray eject")
...
## Close:
get shell("drutil tray close")
...

Tested and works!

Since this is still listed in the dictionary you could try this on Windows:

Code: Select all

...
## Open:
get MCISendString("set cdaudio door open")
...
## Close
get MCISendString("set cdaudio door closed")
...

No idea if and how it will work if you have more than one CD/DVD device attached to your machine.

For Windows you may find the answer in the link below in combination with using the 'get shell' or 'get MCISendString' commands in livecode as the great Klaus suggested .

Never tried it myself so you have to experiment
