VS 2008 Dividing Numbers - Result To Be Displayed On A Eight Decimal Number
Jul 30, 2009
I'm trying to do this division and the result to be displayed on a eight decimal number.
Dim r1 As Integer
Dim r2 As Double
r1 = Val(TextBox16.Text)
r2 = r1 / 60
TextBox18.Text = FormatNumber(r2, 8)
The value or R1 on this case is 273.4 but it varies according with the result obtained so I can not allocate a constant number to r1. The problem is the result that I am getting is 4,55000000 instead of 4.5566666

I have a stopwatch in my program. I start the stopwatch with the start button I created. When I stop it it gives the results of the time in a label that I have named labelTime. I have a Calculate button I have created. I also have a label I have named calcResult. I want to click the Calculate button and divide the stopwatch result (labelTime) by 60. I want the results of this calculation to be displayed in the label calcResult. I keep getting errors saying labelTime is a string value. I believe I will need my calcResult to be a Decimal.

correct syntax to format decimals. I want 2 decimal places even if the result is an even number i.e. I want 40 to show as 40.00 and 40.6666667 to show as 40.67.

I'm trying to limit the number of decimal values to 3 in numbers such as .3125 but I also have numbers such as .5 which I need to leave as is.
how can I determine if a number is 4 decimal places and cut off the last number.. I don't want to round up either.. .3125 should be .312 not .313 and .5 should stay at .5 and not .500.

start with a sign symbol (+ or -)
a fixed number of fraction digits
no decimal separator
right aligned
pre-padded with "0"'s

I was wondering how can I get the two numbers right of the decimal period? If I had 2.85874125639, I would want to get this: 2.86 since it was rounded...

In short let's say i have a form with a text box and a label. I am going to insert a number for example "1365" in the text box and then in the forms label it'll output "one thousand three hundred sixty five".

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

intLoginTime = txtLoginTime.Text
intLogoutTime = txtLogoutTime.Text

The problem is that the numbers seem to round after the decimal point, so if I entered a login-time of 8.15 and log-out 9.30, instead of showing 1.15 as the difference, it shows '1'. is there a way around this?

I am using the WebBrowser control with VB.Net (2010 Express) to get exchange rates from ft.com. (Note: I realise that there are simpler ways of getting exchange rates, but it is a learning exercise as much as anything else). I am navigating to a webpage, setting the values of a textbox and two listboxes, and then trying to get the resulting exchange rate which will be displayed as text. Trouble is, the result is not being displayed. I probably need to trigger an event to force the page to update, but I have tried this and it hasn't worked. [code] The 'onchange' event is intended to trigger an update, but it doesn't. I have tried a few variations without success (including "invokeMember"). So at the moment the amount and the to/from currencies are correctly set on the page, but the resulting rate is not shown.

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'm a police officer and trying to write a program which will print the officers name, start and end dates and select a random road from an array that he/she will be responsible for during the time period. Right now I only have 6 entered to try and get the hang of this. It has a drop down list of persons names, a start date picker and an end date picker. The program will then display the name, start and end date and select a random road from the array. [code]...

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"?

my application has a data table, one of the column set as decimal type to store number, data is read from a text file and store into the data table, then display in a datagridview, I found when that number is only 1 digit, that cell displays nothing (I think no number is being store in that cell), if I type a 1 digit number into that cell is fine. for example,
1.1 [ok]
12 [ok]
0.15 [ok]
4 [not display]
9 [not display]
-23.8 [ok]
so which data type I should use on this column, in order to display all this possible numbers

The end result is baffling me here are 2 examples when I debug
Mine: 640.1 * 49 = 31364.9
Debugger: 640.1 * 49 = 31360 ( not right needs to show the correct decimal )
Mine: .775 * 3 = 2.325
Debugger: .775 * 3 = 2.325 ( shows it perfectly???)

I've used a numericupdown to select a number and then save it to a .dat file
When i try to display the integer in a listbox, it appears as a random sequence of numbers.
for example, if i input 200 into the numbericupdown, when displayed in the listbox, it is shown as 538976366
Is it an error with the properties with either the numericupdown or the listbox? or do you need to see my code?
let me know if you need any more information or code

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.
