C# - Globalized Custom Number Formatting - Variable Decimal Points?
May 5, 2011
I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?
I am using datatable.comput to calculate the avg of a data column. The data column's datatype = integer, so it returns a integer avg value as well. Can i make it to return double value?
I'm having a bit of an issue getting the number formatting of VB .NET 3.5 to work just right for me. I have to convert numbers to scientific notation, with 2 digits for the exponent and 6 digits after the decimal. I've been able to get this for numbers that have enough digits, but for other numbers, it truncates the number to use as few digits as possible. For example, I would like 0 to be converted to 0.000000e00, or 123.4 to be 1.234000e02.
In window textbox, I'd like to just allow 2 decimal points only. I could set text box only numeric but don't know how to limit 2 decimal points.[code]...
I am working on a program where specific strings are being read from a file and displayed in a listview. Some of the strings represent money values though the file has no decimal points. I would like to add a decimal point before the last 2 digits of prices, quantities, and freights when displayed in the listview (not add two decimal places but actually insert the decimal point into the string). I would like to be able to keep most of the code I already have though, and I have no clue how to accomplish this. Here is the code I am using to fill the listview:
VB2010 Public Class Form1 Dim dates1() As String[code].......
I've found plenty of examples of accepting numbers only in a text box, but the code won't allow decimal points. This is crucial because I'm dealing with US currency.
01.' Force numbers only in a text box 02.' place this in the 'Keypress' event of a text box 03.

How can I change the IF statement to accept the ascii code of decimal points? Then... how can I make sure the user doesn't enter 354.5.3535.5.0 as a number? Is there some sort of built in library in VB that has a pattern matching for US currency or do I have to write it myself?
Why my math keeps getting rounded to 0 decimal points by default?When I do this I get return value of 1
Private Sub Button4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim numb1 As Integer numb1 = 100 / 78 MsgBox(numb1) End Sub
How to get that value up to two decimal points (like 0.00)?
I have designed a unit converter that converts between different units. The value and unit to be converted from are entered in the first text box, for example "1 km" and the unit to be converted to is entered in the second text box. Then after pressing the calculate button, the new value will be displayed in the second text box as the output. By default the output will be specified to two decimal places. However, if the input has any number of decimal places, for example "1.045 km" the output should be displayed to the same decimal place, in this case 3.Displaying the output to two decimal places was easy enough to figure out, I just used:
FormatNumber(finalValue, 2) But I'm completely stuck on the other part however and I'm wondering if anyone here has any suggestions. I thought about doing something like this:
I have an app that deals with currency. For display purposes I use the nifty VB FormatCurrency function which will format based on the OS's region setting. So, if in France you might get 123,45 where in the US you would get 123.45. To perform calculation on these amounts I use CDec() to convert to decimal.
My problem is that when I convert the Decimal to a String using toString() it formats according to the currently set region. I need to be able to always convert the decimal into a String representation for the US, i.e. with decimal points. I thought I would be able to do something similar to this: .toString("#0.00")
I'm a noob, so please bear with me. I'm working with VB in Visual Studio 2008. I have an application that displays dollar amounts. With the application installed on my desktop all of the dollar values display with 2 decimal places. However, after moving the application to the server and executing from there, trailing zeroes after the decimal point are lost.
For example - 7.00 displays as 7 - 10.60 displays as 10.6 I'm guessing there's an options file somewhere that determines how these numbers are displaying but I have no idea what that file might be.
Can someone tell me how to get both digits following the decimal point to display all of the time?
I am generating excel from code.I am trying to customize the cells through .net code.and I also want to add the localization , so that after generating the excel when the user tries to enter the decimal it should take that locale number format.how to format decimals with thousand seperator en-US a number looks like 1,000.45 and Dutch-Belgium it becomes 1.000,45 I mentioned decimal in my code as worksheet.Range(Range).NumberFormat = "###,###.##" How to chnage this format for different locales.
I'm fairly certain I'm missing the obvious, but I'm trying to force a datagridview cell to format the contents of a cell to two decimal places when the value is changed e.g. the user enters 20 in a cell and it's formatted to 20.00 when the cell is moved away from.
I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value
Private Sub BankGrid_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Dim grid As DataGridView = DirectCast(sender, DataGridView)
I have a VB Application that is loading an Array with Numbers from the Sequel Server that have numbers 315054 no cents and leaving the .00 off even numbers. I need to write out the number to a textfile that has 14 zero's to the left removing the decimal point from the number.
The Number should format and be written out like this: 00000031505400 in the text file.
My coding does this as long as the even number has a decimal point .00 but if the number comes in as 315054 into my array my coding gives an Argument error with the coding below. SCreditTextBox1 = Microsoft.VisualBasic.Right("00000000000000" & Microsoft.VisualBasic.Left(_sData(Irow, 7), _sData(Irow, 7, ".") - 1) & _ Microsoft.VisualBasic.Right(_sData(Irow, 7), 2), 14) Is there a way to check for no decimal point and then place the number with no .00 as 00000031505400?
The accounting people are entering the numbers into the server this way incorrectly. The .00 is suppose to be entered with it, but not all even numbers are entered this way without .00, just a few, but I need to check the number to see if there are decimals and without decimals do something. Could my coding be re-written to account for not having the .00 and to format the number correctly to avoid the argument error?
I need for any number to format with: $3,000.00 would appear in server as 3000 or 3000.00 and should write out like this below: I need to check for decimals and without decimals and writeout the format like this below: 00000000300000.
