In a project I'm working on, I've assigned each user a unique ID with the following code. [code] However, I want to replace the number at the end (RecordCount) with a randomly generated sequence of 4 numbers (no 2 can be the same).
View 3 RepliesBelow is a form which produces a graph, the idea is to produce 6 random numbers from a range (0,6) place the numbers in an array then use these numbers to produce columns on the graph, however at the moment it is using the numbers more than once, how can I get it to just use the values once only in the array.

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
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.
Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work
Beginning VB 2010, had a project that requires us to create a list box of 25 randomly generated 0s or 1s. Problem is when I put the loop in, it only repeats the same random number, not different one each loop. What am I doing wrong?This is the code I have so far...Code in Question:
'Declare new random object
Dim RandomGenerator As New Random

Write a function that will take one integer input parameter, create a sequence of numbers stored in an array from 0 to that number, and the numbers are a summation. For example, given 7
View 17 RepliesBasically, I'm not sure if I'm thinking along the correct lines when trying to break this down. The program is supposed to display the question "How much is _ x _?" with _ being a randomly generated number between 0-9 which I have in a label. The student inputs the answer and clicks the "Answer" button. If he gets it right, the label below outputs "Very Good!" and automatically puts a new question in the above label. If the student gets it incorrect, the output is "No, Please try again." and the student keeps trying until the question is answered correctly.
My method of thinking on this is that the random.object generator is input first so the question with the numbers are output in the first label. Then, under the Sub answer.button, enter the statements that will either check and refer to the above statements to get a new question or have the student try again until it's answered correctly. One of the other criteria for this is that I have to use a function for the calculation. Would the function statement, because it has to return a value, go before the answer.button code or after?
Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.

View 2 RepliesI 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 have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.
View 2 RepliesI am setting up a game for my final visual basic program in my computer programming class, and it is supposed to compare what you type into a textbox to a randomly generated password, and then return whether the last character you entered had a higher, lower or the exact same ascii value as the corresponding character in the randomly generated password. Well, in order to test it, I set up labels to compare the two characters... when you type in ALT + 125, the ascii value returns 125, as it should, and it says that the ascii value of the correct character is 142. I typed in ALT + 142, and the character's ascii value, according to what the label puts out, is 196... obviously its converting dec into hex or oct or something... but how do I fix it?I can also tell you that when I typed in 196 to see if it was reversed or something stupid like that, it printed that the ascii value was 49... what's up with that?!

I want to extract numbers from a sequence. Example: if the number is 1890928 i want to extract "1" or "89" or "909". I think it's something with left or center but i don't know how.
View 2 RepliesThen you have to take that same range and find the product of all odd numbers between said sequence. I figured out how to find the product but only if the lowest number is also an odd number. For example, if I put in the values 1 and 7 the product is 105 which is correct. But if I put in 2 and 5 the product somehow becomes 10, when it should be 15.I have to use the MOD function to distinguish between even and odd numbers, which I know how to do however it's still not working out correctly for some reason and I'm completely stuck.

How can I do it?
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....

What I'm doing is trying to generate a number 1 through 4 which was easy enough but next what i want to do is assign four variables with the four generated numbers which i do. My next problem is making sure each different variable gets a different number which is a nightmare for me. I tried doing a For loop to see if it would keep generating until it was a completely different number though it would be a 25% chance to get that possibility (actually less because the other three numbers can be the same at this point) i give it 1,000,000 and still 1/4 of the time the first number is the same as one of the other three.
