Convert String To Integer With Variable Decimal Sign?
Nov 22, 2011I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

View 4 RepliesC# - Globalized Custom Number Formatting - Variable Decimal Points?
May 5, 2011I'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?

View 2 RepliesTesting The Value Of An Integer Type In VB
Jun 2, 2010I have an int datatype in my SQL database table (NULLS allowed).
Three values of this int datatype are significant: NULL, 0 and > 0.
I create a variable with:
Dim IntType as Integer = Nothing
And then, using SQL Linq, transfer the value from the int datatype in the table into the variable.
If the int datatype is NULL, I leave IntType = Nothing.
Now, when I test the value of IntType:
If IntType Is Nothing Then
gives an error because cannot use Is with an integer variable.
So I tried:
If IsDbNull(IntType) Then
is never true, even when IntType is set to nothing.
In fact, if IntType is set to Nothing, whilst debugging, IntType = 0 !!!

Asp.net - Converting Decimal In A Label To An Integer?
Mar 28, 2011Currently using VS2008, VB.NET, SQL.
I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?
Conversion To Integer, Decimal, Double
Jun 9, 2011So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.

May 13, 2010I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur
IGroupe
IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.
