Hi WS,

I have seen the sample too, however I that stream does nothing in my
opinion, can you try if this fits you?

Private Sub WriteSchemaWith XmlTextWriter(t hisDataSet As DataSet)
thisDataSet.Wri teXmlSchema("My Path")
End Sub

Re: writexmlschema not working

that works

but the reason it wasnt working before i figrued out was because i was using
a custom inherited dataset and i guess that i had not programed that code in
so it did not work

but the msdn tutorials a lot of them dont work its like they are made in a
earlier version of vb.net

thanks again for your help
