this exception information because it threw up on their PC.

The date format was not recognised by the database. This is common when
using this type of date format without specifying a culture when
converting it.
Specify a Culture (or FormatInfo) when parsing the string, and don't
convert it back to a string before putting it in the table.

Terry,
Did you ever tried the method CDate from the extendened Net Library
Microsoft Visual Basic.
Almost all conversion functions have no relation anymore with VB6 but are
optimized Net ones.

'CDate' is a language feature, not a library feature.

Will this work?
dr.Item("Date") =Date.Parse(dt. Trim,System.Glo balization.Cult ureInfo.Current Culture.DateTim eFormat)
Along the same lines, I have this code:
DLDT.Columns("F ileSize").DataT ype = GetType(Double)
dr.Item("FileSi ze") = CType(stringVar ,Double)
And while checking to see if my Date change worked by changing the language
settings, the FileSize column went blank. So I guess I need to figure out
how to make the FileSize column global...
Herfried,
Are you sure than I cannot use it in C# in my idea?

Using CurrentCulture will give you the same effect as not specifying any
culture at all, as that is what's used by default. CurrentCulture
contains the culture selected by the user, and it will differ on
different computers. Create a CultureInfo object for the culture that
you want to use for the conversion.

The decimal separator or a floating point number is also culture
dependand. Use the Double.Parse method to parse the string, so that you
can specify the culture to use for the conversion.
