Hello PCKOST,
Thank you for your inquiry regarding capturing keystrokes on a PDA. I assume that the up, down, and side keystrokes that you mentioned are arrow keys located on the virtual keyboard. The only event handled by LabVIEW 7.0 in the Event Structure (structures sub-pallet) is the Value Change event for the PDA. In this case the only possible solution would be to monitor a value change that is controlled by these keys. More events for PDA�s will be accessible in LabVIEW 7.1 however. By subscribing to the Standard Service Program (SSP) for LabVIEW you would receive periodic updates whenever they are available.
I hope this helps. Let me know if I can further assist you.
