What's the fastest way to randomly generate numbers, either randomly or simulating random? I don't really need a true random number generator, it would be acceptable to simulate random. I tried other random simulation methods but none were faster than this. Here's the fastest way I have now:
[Code]...
I am making an application that randomly generates numbers. I then have to find out if those numbers are even or odd. Then place them in the corresponding array ( EvenNumbers() or OddNumbers() ). Then display the random numbers array then the even and odd numbers array. I am up to the point where I have the generated numbers and can tell if they are even or odd, but can't get them into an array. I am trying to do it like this....

View 2 RepliesAn assignment in my computing class is to find if any numbers from a set of 5 add up to 15, if they do award a point. I cannot figure out how to find if multiple specific numbers can be made from adding up a random set of 5 numbers. Are they any algorithms specific to this? Also it has to be written in visual basic.

dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
I have to make a card game called SNAP. The point of the game is that two players will flip their card and if they match then one of them have to call out snap. The first one to call out snap gets the card.
I'm having trouble on getting the cards to generate randomly but match every now and then.
how to do this certain section of it. I want it to take a group of first names and randomly pair one with a last name randomly selected from a separate group. something like this:
Group 1-BobJoeBrianJillJorge
Group 2-SandersRientzLopezGumpStaudmann then output something like "Brian Staudmann" or "Jorge Gump"
Except I want a significantly larger selection of first and last names in each group. Would it be best to save them in an array? A String? Parse from textfiles?
You see three buttons which all contains a one digit number (1, 2 and 3) at the start of running a program. There is one other button stating "Randomize" and when you hit this randomize button all the three buttons that were first containing 1, 2 and 3 are now shuffled in a random order like 2, 3 and 1. In fact, when clicking the randomise button the figures will stay between 1 and 3.I was hoping to sort this out with the following code but it didn't actually work at all:
Dim a, b, c, d, x As Integer
a = Button1.Text
b = Button2.Text

Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.

How long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -
loop
stopwatch stop
display elapsed time
