1ST PART: Fill a DataSet reading from file. Not what I want.
2ND PART: Takes a row from an already filled DataSet and put it into a textbox. Not what I want.
3RD PART: Put back the textbox.text into an already structured, well formed DataSet. Not what I want.

WHAT I WANT: Fill a new empty DataSet from a String. It means that I have a string that IS a dataset in XML form. I could save it to a file, and then read it with the 1ST PART method. But I don't want to save to file! Clear?
this will do the job . either you're not understanding the post or the question :

VB Code:
  1. Dim dr_save As DataRow = new_ds.Tables(0).NewRow()

  2.  Dim mystr = "blah blah"

  3. dr_save(0) = mystr

  4. ds.Tables(0).Rows.Add(dr_save)
