VS 2010 Add Multiple Numbers?
Nov 28, 2010
I am trying to write a console application that adds and undetermined amount of numbers together and then averages them and does some other calculations with them, but I cannot for the life of me figure out how to add many numbers together. I am doing this in a console application and using input boxes and message boxes to Receive and display the data. So the question is, How do I add many numbers together (an undetermined amount, maybe 5 numbers maybe 25 numbers) and then add them.

How do I add, for example, all the numbers in the textbox (they are separated by spaces)? I tried a couple of methods but no luck so far. So for example, this is what the user will input in the textbox:

I have a problem whereby I have 10 text boxes and I don't like to use the same code for each and every text box that allows users to input only numbers, which could be very long and messy coding.
Is there any shortcut that I can set all (not just one) text boxes to allowing user to input only numbers?

I'm designing a program to display 6 random numbers using labels. I know I'll need an array to accomplish this. I am trying to put the integers into the array and displaying them on 6 different labels

I know how to limit a single text box to numbers only but can I use the same sub for all my text boxes or do I have to have a sub for each whith the same code? I think I just need the proper syntax. Below is what I have that works for one on my text boxes:
Private Sub txtPitchRiseTC_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtPitchRiseTC.KeyPress
' allow only numbers and the Backspace key

Im just trying to get a simple multi line label box counting numbers using vbCrLf.
Dim startNumber As Integer
For startNumber = 1 To 4
lblCount.text = "Number = " & startNumber & vbCrLf
Next startNumber
I just want something to display like this in a multi line label, not a textbox:
Number = 1
Number = 2
Number = 3
Number = 4
But... I keep getting something like:
Number = 4
I already turned auto size off and expanded the label.

I have attached the form in initial state. What you don't see in the initial state is 10 hidden labels. I want the loop(which I am calling as a function??) to compute the numbers and display in the labels. Example, if I input 1 for the first term, 3 for the second term and 4 for the total terms, the first 4 labels should become visible and have in them one solution each:
1 - 1
2 - 3
3 - 4
4 - 7
Am I way off with what I want to do? Cannot use arrays, must be a loop.This is the compute button:
Private Sub BtnComp_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles BtnComp.Click
Try

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

Only now, I'm facing this kind of problem, i have a application that until now worked with two different cultures ENG and PT, i always knew this, and i manage to solve all problems related to parsing the numbers, but now i have to change the code, and "protect" the code to handle with others cultures. So i need tips/best way to handle different cultures, and different database culture settings.I think that i shouldn't limit the user, by setting the decimal, the grouping digit, the date time format, etc. . The application should accept the numbers in the user current culture. But this path forces me to putting everywhere the parse/tryparse method.

i need a simple way to get a random number from 2 numbers. This means that for example if my 2 numbers are 3 and 7, i don't need a random number between 3 and 7 that would be like 3,4,5,6,7 but only a random that is either 3 or 7. Meaning not all the numbers between x and y, but either x or y.

I have this
[Code]...
All that is happening above is two players are being compared by scores and a winner is then decided. The calculation works fine and places the winner in the correct spot (txtWinner1.Text) as long as the numbers are positive. So if txtU1D.Text has 13 and txtU2D.Text has 14...txtU2 is the winner. Works with no problems. However, if txtU1 has -1 and txtU2 has -2...it says txtU2 is the winner. The negative scores are common in the game being played so the situation often happens, but may be one player only. It seems to work if one is positive and one is negative, but if both are negative it thinks the higher negative number is the winner for some reason. So it will give the win to someone who has -9 over someone who is -4.

I am making a calculator that accepts large number (represented as strings) and performs basic math functions on them. So far I have Add and Multiply figured out.
Here is addition
Private Function Add(ByVal Number1 As String, ByVal Number2 As String) As String
Dim num1, num2, r, total As New Integer
Dim sum As String = ""
[Code].....
I saw something like this in the code bank but the examples there were from VB6(?) and were hugely inefficient (compared his Add and Multiply examples to mine, his having way more code and loops.)

I have an application in which a streamwriter is used to save values to a file. It all works fine, except I'm curious as to why the values in the file would be rounded. They are rounded with enough accuracy that it doesn't really matter to the app, but I'd like to know why this is happening. My line of code that writes the line is.

I figured there would be some simple way to set up some textboxes to allow ONLY numbers or ONLY characters, however I haven't found an easy way yet.
Is there a simple trick to setting something like this up? And if so, how would I do it?

I've created a program that allows a user to input numbers and then outputs the highest and lowest number when the user is done (the user indicates this by using a sentinel value of -99). My only problem is that it keeps putting out the numbers reversed (largest as smallest and vice versa).
The code is below.
Module Module1
Sub Main()
'Declare Variables
Dim number, smallestNumber, largestNumber As Integer
'Get numbers from user
[Code] .....
Is it a no-no to have a module within a module like I do there? So far there is no mention of such in the book but I can't find an example of it happening yet either? The instructor wants modules to perform the input and return of information and the only way I could figure out it doing both of those things (rather than using the main module for user input) was to call the module that figures hi/lo within the module that asks for the numbers. I'm really unsure on this part.

I'm new to the forums and VB programming in general, so I only have a very basic understanding of VB commands, but I still have a good grasp on logic and the like.

In the code window near the line numbers which are set to show, a vertical band of green exists with a short band of yellow which seems to be near the part where I am entering code.
What is the significance and usefuleness of this?

So I have an assignment dealing with arrays for school but first I will start it off with the simple question as to where I am stuck now. I was wondering what the simplest way is to declare all the numbers in an array without going down the list one by one ( ArrayA(1) = 1, ArrayA(2) = 3 and so on.) I was wondering if the simplest way to do this is just by putting: ArrayA = ArrayA += 1 or what the simplest way to do this is.
