Marty Hi, If I don't know that my (or any) windows 2k regional setting for the decimal symbol is the dot (".") and I want to do this: 1- Dim dblOutput As Double 2- Dim strInput As String 3- strInput = "123,8" 4- dblOutput = Convert.ToDouble(strInput) How can I avoid an error at line four ? And get it converted to double to have this output : 123.8 Thanks a lot! Marty Reply to this message...        Herfried K. Wagner [MVP] (VIP) * Marty <Click here to reveal e-mail address> scripsit: [Original message clipped] I suggest to store the values formatted in the invariant culture (this culture uses "." instead of ",") and then parse the number using this culture: \\\ Dim d As Double = 22.34234 Dim s As String = d.ToString(System.Globalization.CultureInfo.InvariantCulture) MsgBox(s) d = Double.Parse(s, System.Globalization.CultureInfo.InvariantCulture) MsgBox(d.ToString()) /// -- M S Herfried K.

Wagner [MVP] (VIP) * Marty <Click here to reveal e-mail address> scripsit: [Original message clipped] No. I was referring to values that are stored in a file, for example. If the user types in "12,123", on an en-US system 'Double.Parse' will return 12,123.0 whereas on an de-DE system it would return 12.123. -- M S Herfried K.
