Question

I have a progress bar with Minimum=0 and Maximum=1000.
Now I have long FileSize=1454545454 and long BytesSent (example). How to calculate progress bar position? I always lose precision or something :/

Edit:
Solved… I forgot to cast like: (decimal) BytesSent. You guys did same:P
Thx for answers. Debbuger always helps.

Answer 1

progressBar.Value = (int)(
    progressBar.Minimum + ((double)BytesSent / FileSize) *
                          (progressBar.Maximum - progressBar.Minimum));

Or:

progressBar.Minimum = 0;
progressBar.Maximum = FileSize;
progressBar.Value = BytesSent;
