Adding data (autoincrement) into a xml file with the help of a dataset

Hi,

I have a strange problem with my xml file. In the schema of this xml
file I have set one column to autoincrement. When I enter the data in
my xml file directly, the autoincrement-column gets its correct
values.

Now I want to add new data with the help of a dataset. I use the
following lines of code:

Dim ds_functions As New DataSet
ds_functions.ReadXml("Test.xml")

Dim drCurrent As DataRow
drCurrent = ds_functions.Tables(0).NewRow
drCurrent(1) = Me.txt_bla.Text
ds_functions.Tables(0).Rows.Add(drCurrent)

Dim sw As System.IO.StreamWriter = New
System.IO.StreamWriter("Test.xml")
sw.Write(ds_functions.GetXml.ToString) sw.Flush()
sw.Close()

If I have a look at the data of the new created xml file the
autoincrement-column has the correct value (perfect), but this data is
not available in the xml-view of this file (in Visual Studio.NET
2003). This is a problem because when I try to read the new xml file
with the help of a dataset, the values of the ID column are missing.

Hope anyone can help me.
Thanks in advance,
Marko
