Eliminate Duplicate Random Numbers?
Nov 25, 2011So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called. Is there a way that the program can read the items in the list box and not generate (Randomly) the same value again to be displayed in the label.This is what i have:
Callnum = Int(75 * Rnd() + 1)
lstNumbersCalled.Items.Add(lblCallLetter.Text & " " & Callnum)

Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?
May 26, 2011I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

Nov 26, 2011I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything.

Nov 24, 2009I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.

Nov 26, 2011VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
