Hi, I'm Emanuele.  
I need some advice, before writing I browsed the forums, but I couldn't find a solution to my problem.

I want to write a tag when I press the enter key (not the windows keyboard) of the on-screen keyboard that appears in runtime, but I didn't find anything about it, I can only do it from the client event, but with the real keyboard that is not connected because the panel PC is only touch.

Can anyone help me?

Thanks

I don't quite understand what you're asking, but maybe this helps.

You can invoke the numeric keypad from a script:

> **[system.gui.showNumericKeypad | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-gui/system-gui-show-NumericKeypad)**
>
> Displays a modal on-screen numeric keypad, allowing for arbitrary numeric entry using the mouse, or a finger on a touchscreen monitor.

The function is _blocking_, meaning script execution will not continue until the user has either pressed 'Ok' or 'Cancel' on the keypad.  
So you can capture the return value in a variable, perform some validation on it, and then write it to a tag with `system.tag.writeBlocking`.

I want to write a tag when I press OK or Cancel on screen keypad, can I capture the Press event of the OK button?

example I want to write a string tag, if I press the OK button I write "OK", if I press Cancel I write "Cancel"

If it is possible, how can I do it?

Thanks

No, you can't add listeners or in any other way inspect what's happening while the keypad is open - it's modal, meaning all other event processing, including scripts, is paused.

The way the function works means that it will _always_ return a value. If the user chooses to cancel, the returned value will be the same as whatever the original value was. Depending on your process, you could invoke it with some definitely-not-correct value, such as 0, and check whether the return value was 0. That's as good as you can get **with the built in keypad and scripting function**.

If you want more customization, you would have to make your own popup window that acts as a keypad, and be in charge of opening it whenever appropriate.
