Sorry, I meant to tell you...

When I tried your suggestion of immediately creating another dataset and trying to read the file just "created", as in:

          Dim ds As DataSet = New DataSet
 
           ds.WriteXml("\Foo.xml")
           MsgBox("Just executed the WriteXML command")
           Dim anotherDs = New DataSet
 
           anotherDs.ReadXml ("\Foo.xml")

            MsgBox("Just executed the ReadXML command")

it executes with no exceptions --- and no file. I've looked for the file at all levels of the directory from which the app is running, both manually and via Search. I already know where the app is READING the XML file from and, since the path I give the writeXML function is exactly the same, it seems the file should be there. If it is, though, it's invisible.

As posted earlier, a programmer at our corporate office tried to write XML within both Windows CE and Pocket PC emulators and it worked. This is a very frustrating mystery...
