Arduino button: as a hardware button for visual basic.

Hi guys! I'm new here. I know my problem is kinda simple, but I can't seem to find a way on how I can control an application from an Arduino with a button to Visual basic application.

I just want the hardware side to control a visual basic application through serial com.
Though in my case when I was searching, all I can see was controlling an Arduino board with Visual basic.

Help. :smiley:

P.S.

Have a Happy New Year... :smiley:
