Adds Numbers Between 2 Inputed Numbers
Oct 26, 2009
I am very new to visual basic and was recently asked to teach a course without any formal training. I am writing a program that adds the numbers between 2 inputed numbers. I need to display the sum of the numbers between the inputed numbers and the expression used to create the sum.For example: If 10 and 15 were inputed the answer label would display the following 10+11+12+13+14+15=75..The code is properly generating the sum but I can not figure out how to display the expression used to generate the sum. [code]

I have to create program that adds the whole numbers from 1 to 1000 and displays the sum in the label. Create a variation of this program that allows the user to specify any starting whole number and any ending whole number (10,000 or lower) and then adds all the whole numbers in that range. Allow for the possibility that a user may start with a high number and end with a low number. Format the label so that commas are displayed and there are no decimal places showing. I need help with the codes.

I am wanting to allow a user to enter a number and depending on what number is entered, it will allow that many entries. For example, if 5 is entered, the user has to enter 5 numbers. Those 5 numbers will then be added together.I 6 is entered, 6 total numbers will be added.I was trying to do this with a for next loop but I wasn't getting anywhere.

I have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g. [43] [85] [93] [1] [0] [17]..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB

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.

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

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.

am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.

I am working on an assignment that will display the forst 10 fibonacci numbers in sequence. However when my results are displayed, the numbers are all stacked on top of each other like this: 011235813213455. I have tried to play with it but i can't seem to get my numbeers to space out or even maybe have a comma "," betweeen each number.[code]

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

I have an id called "AM01". I separated them by truncating the numbers out and increase it by 1 each time I want to add a new record. Therefore before I add the record, I would have to combine them back. I managed to truncate them and combine them back. However, the results turn out to be "AM2" instead of "AM02". So, is there a way where I could make the numbers as "02" instead of just "2"?

Basically, I want to divide two numbers together and they should be 2 random numbers from 1-12 (I have done that part) but, the answer should be a whole number (i.e. Integer, so no decimal points etc) So, I did the following:
' Initialize the random-number generator.
Randomize()
' Generate random value between 1 and 12.
Dim value5 As Integer = CInt(Int((12 * Rnd()) + 1))
[code]....
but the problem here is that the program crashes after only a few clicks on the button. So I guess the question is: How can I make the program generate two numbers (from 1-12) that when divided become a whole number?(Is there any code that may tell the random generator that I want the numbers to be even?-so all even numbers from 1-12?)

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 .

I am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
