i need to count and add all numbers that are divisible by 2,3 and 5 inclusively ( the answer is 30, 60, 90 sum is 180). I tried running a loop and a true false isnumber. what am i doing wrong? all i have is two textboxes and a button Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

In my order program, I need to determine if the quantity ordered is full boxes.For example - all of our parts/products have different box quantities, and when a customer orders a certain quantity, I want it to do nothing when I type in the quantity IF the order quantity is even boxes, If it is not even boxes, I want a pop up form with three radio buttons to come up. The three radio buttons will have the next higher even box quantity, the next lower box quantity, and to keep the current quantity and apply a broken box charge. I have this pop-up form done except for determining if the order quantity is an even number of boxes, and then determining the next higher and next lower.
Just to clarify - let's say a customer orders a part that has 60 pieces per box. If he orders 180 pieces, nothing happens and you can continue to put the order on. If he orders 200 pieces, a pop-up form with 3 selections - "keep current quantity and apply broken box charge", or "Change Quantity to 240", or "Change Quantity to 180" comes up.
designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

i have already calculated the avg of the values in the listbox, and now i have to count all the values thats less then avg (in a function), anyone that knows how to do that? help please. i looked at google to try and get a clue but could not find anything.
View 2 RepliesMy loop that needs to count and accumulate the numbers from a list box does not work. When I debug it reads the first line of the Do While loop then jumps to the code where it would average the numbers. Here is my code:
'calculate average
'get first item in list box
lstListBox.SelectedIndex = 0

I need to count a large amount numbers in short time.As a result the CPU jumps to 40-60% on 4-core PC.Which is extremely high.I have any idea that will lock up the thread for some time, but not actually slow or reduce the amount of files that are allowed to be counted per a giving time period.

I'm trying to check if when x is divisible by 5 then it makes y true.
basically: if x / 5 = "positive integer" then y = true.....
how do you check if a number is divisible by 5?
For example, how would I get the # "220" from the number "229". Or the number "300" from "309"? The only way I've found to do this is using string stuff, but I'm afraid of the overhead for strings?
View 15 RepliesI have run into a snag in my loop program. I was able to figure out the maxium sum and average of the sum. But am not able to figure out how to:
1) List the minimum value
2) List the sum of the numers divisible by 5.
These are the numbers.text displayed:

I was wondering what the fastest way is to check for divisibility in VB.NET.I tried the following two functions, but I feel as if there are more efficient techniques.
Function isDivisible(x As Integer, d As Integer) As Boolean
Return Math.floor(x / d) = x / d
End Function
Another one I came up with:
Function isDivisible(x As Integer, d As Integer) As Boolean
Dim v = x / d
Dim w As Integer = v
Return v = w
End Function

I'm converting some php code that tries to get a string to a length that is divisible by a certain number, say 10. To do so it appends "�" to the string to make up for the difference. In other words, it does something like:
dim difference as integer = 10 - (str.Length Mod 10)
for i as integer = 1 to difference
str += "�"
next
But the problem for me is that "�", which is the ascii code for the null character, is two strings and I don't believe that when VB loops over resultant string it will view that as one character. what could I append the string with to retain the expected behavior?
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.
I have added a column to a Datatable called CallsPerDay which is there to tell me how many telephone calls have been made on a particular day or days.Is there a datacolumn.expression which will allow me to Filter on the day, count the rows and then populate this added column with the result.
View 1 RepliesI have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?
this its a very silly problem i have with CheckBoxList control, i dont know if its just me or what but the whole idea of the control its just great but the implementation its very confusing.
im trying to eval something like this
if CheckBoxList.Items.Item(CheckBoxList.Items.Count-1).Checked=true then.....
or something like
CheckBoxList.CheckedItems.Item(CheckBoxList.Items.Count-1) = Checked then...
the problem its that i dont know how does the checkboxlist works but it just sucks that they had to make it so confuising....
i've handled lots and lots of collection controls and they all work in a similar and simple
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.
View 2 RepliesIm 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."

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.

View 1 RepliesI 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.
