Rounding Whole Numbers (Integers)
Mar 17, 2010
I'm a college student, working on a small project, and I'm having some trouble understanding the Round command on VB. The project is very simple and straight forward, just a simple Bail Bonds program to calculate the bail plus a 10% fee. However, i want to integrate a kind of "promotion", where for every $1000 of the bail cost, $5 would be deducted. I know the formula for this, which is reasonable simple, i just need to know how to round the Bail variable to the nearest 1000 so i can do this calculation.

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

I haven't used VBA in a very very long time. So, go easy on me. I'm trying to do an IF THEN ELSE function where whatever the pVal cell says, Excel will input the correct currency value in the next cell. I have the cell format in the Excel workbook set to currency with 2 decimal places. However, when I add the UDF, it rounds up! I basically copied and pasted this code from an online website, but theirs did not have any decimals. I've tried calcvalue = Format("48.95","Currency") but it still rounds. I'm sure I'm leaving out something simple. Here's my function formula so far.

I have a series of text boxes with numbers. They are an array called txtBF(0 to 16). I am trying to take the value that is to be displayed in the text box and make it have only one decimal place. I have tried using this code below but I keep getting an error message Run Time Error 13: Type Mismatch.
txtBF(11).text = Round(txtBF(11).text, 1)
and I have also tried this
txtBF(11).text = Math.Round(txtBF(11).text, 1)

i know this may soiund a bit of a n00bish question or 1 that pops out every now and then, but i am havin trouble trying to round off nubers.basically i ahev this label where a value i s inputted by the system after it goes thruogh user inputting so:1)user inputs somehting (* by somethingh)2) user input (* by something )etc etc.val(label1.text) = the additon of all those user inputs---to make life easier lets ust say user input1 = user input 2 k sometimes the val of label1 becomes a decimal point like 3453453.666777 etc when this happens i just want to round up to 2 decimal places i have looked on msdn for help which gave me:

using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer
[code]....
I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.

Is there a correct way of doing this in vb.net? I want to read a file as a set of numbers such as long integers ,say the file contains the string "Hello World - Its a beautiful day blah blah blah" This would read as a set of long integers that are 4 bytes long
ie ascii (hex)
48 65 6C 6C 6F 20 57 6F
H e l l o W o
etc and that would also be an 4 byte word represented as a number 1819043144 thus stepping through the file 4 bytes at a time. Instead of reading and looking for certain words in the file I would look for certain numbers, thus eliminating read errors in certain file types. I coded this type of thing in vb6 before , this would be done with the 'get' method and a file pointer. I have managed to read it a byte at a time with this code but I am unsure where to go with it as the 'get' method isn't in vb.net

How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.

I have very basic question, I'm really not familiar with vb.net.
I have code like this: Dim minutes As Integer = (55 / 60)
I want this to return 0 to me, integer 0 (no decimals), but vb.net rounds this to 1.
Can someone hint me up how to accomplish this ?
edit. OK for those with same problem try dividing with (Yeah, it's not escape character in vb.net)

I need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.

What is the rounding method that VB.NET uses when a double is used in a for statement like this. It looks like 5.5 is rounded to 6 and 10.5 is rounded to 10. The output of the program is 6 7 8 9 10
Sub Main()
Dim A As Double
Dim B As Double
