Delete Carriage return

I am reading from a file and writing to another file.
I am getting an extra carriage return, after reading
from source. How could i delete extra carriage
return at end of the file.

Any light shed would be helpful.

Thanks in advance

t = Replace(txtFind.Text, vbCrLf, "")

Still my problem is not solved. How do i know the
End of file. i am reading the whole file and writing to another with different name and some changes. How could i use this code and know the end of file.
i = Replace(file, vbCrLf, "")

Thanks

Drop two textboxes and a command button name:
txtFind
txtParagraph - set multiline = true
cmdCarriageEliminator

Code:

---

Option Explicit

Private Sub Form_Resize()
  'vbBack
  Me.WindowState = vbMaximized
  cmdCarriageEliminator.Caption = "Eliminate Only Single Carriage Return - Double Carriage Return Represent Separation of Paragraph"
 
  txtParagraph.Move 0, 0, Me.Width, Me.Height - cmdCarriageEliminator.Height * 3
  txtFind.Move 0, txtParagraph.Height + 240
  cmdCarriageEliminator.Move txtFind.Width + 120, txtParagraph.Height + 240, Me.Width - txtFind.Width - 120
 
  'PURPOSE:Eliminate the following
  txtFind.Text = vbCrLf
 
  'txtParagraph.ScrollBars = vbVertical
End Sub

Private Sub cmdCarriageEliminator_Click()
  'OVERALL:Search for txtFind.Text and delete it
  Dim intPos As Integer
  intPos = 1
 
  Do
      'PURPOSE:Look for txtFind.Text at the current intPos
      intPos = InStr(intPos, txtParagraph.Text, txtFind.Text)
     
      If intPos > 0 Then
         
          'PURPOSE:Check if intPos + Len(txtFind.Text) is another txtFind.Text
          '        If there are two txtFind.Text next too
          '        each other, do not delete it because it
          '        represent a line to separate a paragraph apart.
          If Mid(txtParagraph.Text, intPos + Len(txtFind.Text), Len(txtFind.Text)) = txtFind.Text Then
            'Increase the intPos to skip over
            intPos = intPos + Len(txtFind.Text) + Len(txtFind.Text)
          Else
            'PURPOSE:Replace txtFind.Text with a space
            txtParagraph.Text = Left(txtParagraph.Text, intPos - 1) & " " & Mid(txtParagraph.Text, intPos + Len(txtFind.Text))
          End If
         
      Else
          'PURPOSE:When there is no more txtFind.Text,
          '      intPos will equal 0 - Exist this sub
          Exit Sub
      End If
     
  Loop
End Sub
