I am building an ordering system/POS for a friend’s business.
I’m trying to use a continuous form for the main screen.
I’m having issues with the calculation of the totals in a timely manner. In the attached, I can calculate the totals, but only using a timer event. When the timer kicks off, I get the “Calculating…” message in the status bar. Annoying. Also, if I make the timer fire too often, the screen flashes. Too slow, and my totals aren’t always accurate. Is there a better way?
