iOS Question B4i and barcode scanner

[Daniel Katunar]

Hi,
Is there any way to capture a button on an external keyboard like B4A "activity_keypress" ?, I need this function to read a bar code scanner and process. I do not want to appear in a TextView or that the keyboard appears on the screen.
Thank you
Daniel

Does the soft keyboard appear when the barcode is connected and you set the focus to a text field?

You will need to use a hidden text field (set its Top property to -100).

Hi,

I'm curious as to why you need to use a separate barcode scanner...

For frequent scanning, using the camera as a barcode scanner is expensive in terms of battery consumption. External scanners (e.g. a sled) with an integrated 2D imager are typically faster at reading and will consume less power. Plus the external scanners are often programmable so you can limit the barcode types and edit the data.
