I am learning to use TextFieldParser to read a fixed width text data file.
It works great. I copied code below.
Question: How to stop at the end of each line because I need to add some code?

Using tf As New TextFieldParser(fileName)
tf.TextFieldType = FileIO.FieldType.FixedWidth
tf.SetFieldWidths(60, 30, 20) //three columns

Dim row As String()
While Not tf.EndOfData
row = tf.ReadFields()
For Each field As String In row
MessageBox.Show(field)
//need to add code in the end of each record, how?
