Using a ProgressBar control

  • Artikel

 Hiya all.

I recenlty made a cheezy test program to just roll dice.  I put a ProgressBar control to show give the end user an idea of how many rolls are left.

Well, I noticed that when I tried to do 10000 consecutive rolls, the program slows waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay down.  When I had this all setup as a console app, it screamed no matter how many times I tried to roll the die.  I'm guessing this perf hit is because of the UI in general, but is there anything I can do to speed this up?  Is this something that someone would use threading on to improve perf?

Thanks in advance to anyone who answers.  :)

    I would certainly use another thread. Have one thread handle the rolling of the dice and the other handle the UI.

    Be careful not to starve the UI thread. Read this for more information:

    If you really expect it to scream through a lot of rolls, only update a percentage of the rolls (every 10, or every 100)... It'll still show enough progress to be meaningful.

    Hard to say without seeing the code...
