Key lock

[liveCode]

Is there a code that causes them not to be able to press keys on the keyboard? (by pressing them the computer will not respond)

Hi.

You can trap "rawKeyDown" and "rawkeyUp".

That should prevent anything the user does.

Be careful where you put that, like a frontScript, or at least remember where.

Thanks for the answer
Can you give me an example of the code that causes them not to be able to press the windows start key?

[Klaus]

You can only prevent pressing keys on the keyboard INSIDE of your standalone!
We can NOT control anything outside your app, like the Windows key or whatever...

Is it possible to prevent the mouse from moving outside the stack boundaries?

No.

Yes. Here is a piece of the solution. It will prevent the cursor from moving past the right of the card window:

Code: Select all

on mouseMove x,y
   if item 1 of the mouseLoc > the right of this cd - 20 then set the screenmouseLoc to x - 20 & "," & y + the top of this stack
end mouseMove

You would need to include all four sides of the card window for a complete solution.

The handler I gave is not perfect. System and LC timing will not prevent a fast movement of the mouse from penetrating that border. It will prevent moderate motion, however. The arbitrary values of "20" in the handler just give LC some breathing space. If you reduce those values, you can set up closer to the border, but the ability to blast through increases.

Anyone know how to "Speed up" the reaction time for this handler?

Try it yourself:
Enter a word with less than 10 characters as a response and click "Submit"

Where did that come up?

Well, since you are a moderator I assumed you saw something I did not. Anyway, I do not see that in my thread. Did you delete it?

Craig

[Klaus]

OK, I will explain this very slowly...

I wanted to respond to the namely posting with just "no."
But the forum software does not allow words shorter than 10 characters, therefore that warning appeared
on top of the entry field as seen in my screenshot. So I simply added this error text to satisfy the forum software.

This has nothing to do with being a moderator or no, this will also happen to you in that case!
