Set the redraw frequency at least to 1. Setting it to 0 would otherwise produce a "division by zero" error.
why?
I had a piece of code that used a ProgressBar and set the redraw frequency to a calculated value. In some cases this calculated value was 0 (or just smaller than 1, internally a cast to
intis made). In thesetProgressthe redraw frequency is used for a calculation of the period. There the error happens (and shows that redraw frequency should never be 0).Ticket
There is no ticket concerning this issue. I could do one, if you want.
