I have stores some numbers as strings and also some non-numbers as strings in an array. How do I find and store the numbers in one array and non numbers in another array?
View 9 RepliesI am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

I'm looking for a way to take seven 2 digit numbers & combine them into one number to store in a database.The numbers represent hours for each day of the week & I only have one field to store them in. Then I need to be able to take the stored number & decode it back into the original seven numbers. Anyone have any clever ideas how I can do this?
View 6 RepliesRight 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.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:

Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click
Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")

Am new to programming and i would like your help to this question. [b][color="Red"]Write a declaration statement of an array of integers to store 15 numbers. Initialise the first 5 values.

What number appears more than any other number?This is very important to me, ...I need to find the MODE, of those group of numbers, ...the way that I did it before, I would make 10 TextBoxes, and have another text box to enter the number, and when the number gets entered it would increment the value of which ever textbox the number was in the main textbox, so if I entered a 1 into the main textbox, then the zero in textbox (1), would be incremented to 1, and if another 1 was enered and the button was clicked, the 1 in the Textbox for 1, would be incremented to 2, because 1 has a popularity of 2 now and has apeared 2 times..
Here's some code, to show what I've come up with by myself.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ONE.Text = ONE.Text + 1
End If

I have a group of 3 numbers:

I need to find consecutive numbers in an array and return a string which tells the range and numbers that don't form a range.I found some of the already asked questions but none of them is in VB.Net:Add to array consecutive numbersIf the array of numbers looks like {11,12,67,68,69,70,92,97} then returned string should be of the form 11,12, 67 through 70, 92 and 97.

Just asking if anybody could explain it better, maybe in more detail?

Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed.

I think the best way forward is pass a parameter to the function findnumber.
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.

Example:This is in a label.
Dim number as Integer

Then in the button do

View 3 RepliesIs it possible to store two related numbers in a list and then check them if the are exist in the list?ere is an example of what I did to achieve the above:
Dim CounterConnections, FromN, ToN As Integer
Dim ConnectionsList As New List(Of Integer)
Dim Myrandom As New Random
[code]....
The above code generate two random numbers and store the in a list. I am adding the two numbers to be one so that I can check if they exist in the list.e.g. if the FromN = 7 and ToN = 11 then the list will consist of :
711 and 117
a list to store 11 7 and 7 11 which is capable to be checked later if some some numbers are exists.

i'm trying to get my course done for this class. My question is find the even numbers from 6 through 16. The thing is i'm working with events. How should i do this? i did a lot of research and i did find some code that might work but i'm not sure how it works and understand it. I'm by no means advanced with vb.net i'm just trying to finish this course. What i did find was that i have to use MOD? I'm not even really sure how i can use that with an event? Any code would be awesome to getting me on the road to finish this assignment.
I took this code out of a program that had to find even numbers and it works great but the only downfall is that it starts from 1 and then whatever number you want it to stop at. I only need 6 through 16 .
