title: create and write to a text file in vb.net
body: <p>I'm creating a small vb.net application, and I'm trying trying to write a list of results from a listview to a text file.  I've looked online and found the code to open the save file dialog and write the text file.  When I click save on the save file dialog, I receive an IOException with the message "The process cannot access the file 'C:\thethe.txt' because it is being used by another process."  The text file is created in the correct location, but is empty.  The application quits at this line "Dim fs As New FileStream(saveFileDialog1.FileName, FileMode.OpenOrCreate, FileAccess.Write)"  Thanks in advance for any help.</p>
  
  <pre><code>Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
      Dim myStream As Stream
      Dim saveFileDialog1 As New SaveFileDialog()
  
      saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
      saveFileDialog1.FilterIndex = 2
      saveFileDialog1.RestoreDirectory = True
  
      If saveFileDialog1.ShowDialog() = DialogResult.OK Then
          myStream = saveFileDialog1.OpenFile()
          If (myStream IsNot Nothing) Then
              Dim fs As New FileStream(saveFileDialog1.FileName, FileMode.OpenOrCreate, FileAccess.Write)
              Dim m_streamWriter As New StreamWriter(fs)
              m_streamWriter.Flush()
              'Write to the file using StreamWriter class
              m_streamWriter.BaseStream.Seek(0, SeekOrigin.Begin)
              'write each row of the ListView out to a tab-delimited line in a file
              For i As Integer = 0 To Me.ListView1.Items.Count - 1
                  m_streamWriter.WriteLine(((ListView1.Items(i).Text &amp; vbTab) + ListView1.Items(i).SubItems(0).ToString() &amp; vbTab) + ListView1.Items(i).SubItems(1).ToString())
              Next
              myStream.Close()
          End If
      End If
  
  End Sub
