Cdbl & International Settings

[michele]

Hi, I have a problem with two function: IsNumber() and CDbl() because when I
invoke it they throw an exception.
The problem I think is International Settings, because
NumberDecimalSeparator and NumberDecimalGroup have the same value "."
I can't change this setting on computer by default so what I want to know if
I can change this settings only for my application.

I've used System.Globalization but CDbl use the settings in contro pannel.

Thanks in advice

Hello michelle,

Use system.globalization.cultureinfo.currentculture.nu mberformat.numberdecimalseparator and numbergroupseparator to indicate the separators you want.
Instead of CDbl, use Double.Parse, which uses current thread culture information.

Regards.

Thank you, in fact I've used it and I thought that all was ok but I
discovered that I used I PrintDocument that involved "International
Settings" and I've the applicationt runs ok but I can't print because I
don't know how to set enviroment to PrintDocument.

I don't understand the problem. The PrintPage event runs on the same thread on which you call PrintDocument.Print, so it uses the same environment.

Ok, maybe I missunderstand how to program so can you explain more, it it is
possible.
I've tried to use
System.Globalization.Cultureinfo.Currentculture.Nu mberformat.NumberDecimalSeparator
= ","
but this property is red-only..

Thanks

Yes, michele, the CultureInfo returned by System.Globalization.Cultureinfo.Currentculture is read only. You must replace it. Look at this sample:

Sub Main()

Dim s as String = System.Globalization.CultureInfo.CurrentCulture.Na me

Dim ci As New System.Globalization.CultureInfo(s, True)

System.Threading.Thread.CurrentThread.CurrentCultu re = ci

ci.NumberFormat.NumberDecimalSeparator = ","

Debug.WriteLine(Double.Parse("3,14") * 10)

ci.NumberFormat.NumberDecimalSeparator = "·"

'Debug.WriteLine(Double.Parse("3,14") * 10) 'Error: "," is not part of a number.

Debug.WriteLine(Double.Parse("3·14") * 10)

End Sub

Regards.

Thanks, I write my code with you suggestion and now I thinks that it works
fine but tomorrow I test my application and then I'll tell you if all run.
Thank you again, sincerly Michele
