Version(s): WINDOWS:5.0,97
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Professional Edition for Windows, version 5.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
- Microsoft Visual Basic for Applications version 5.0 
- Microsoft Access 97 
-------------------------------------------------------------------------------

SYMPTOMS
========

When importing a delimited text file into a Jet database, leading spaces are
truncated from field data.

CAUSE
=====

The TEXT IISAM driver for Jet truncates spaces from fields that are not
delimited by the text qualifier character.

RESOLUTION
==========

Make sure you use quotes or other text qualifier around your fields if you need
to preserve leading spaces in your data.

STATUS
======

This behavior is by design.

Steps to Reproduce Behavior
---------------------------

1. Using Notepad, create a text file with the following data:

        ID,Desc
        Line1, Description 1
        Line2," Description 2"

2. Save the file as c:\test.txt.

3. In Visual Basic, create a new project and add a reference for Microsoft DAO
  3.5 Object Library. In Access, open the Northwind.MDB database.

4. Create a new form with a CommandButton (Command1) and add the following
  code:

        Private Sub Command1_Click ()
        Dim db As Database
          Set db = CurrentDB                               ' Access only
          Set db = DBEngine(0).OpenDatabase("biblio.mdb")  ' Visual Basic
          db.Execute "SELECT * INTO TestImport FROM [test#txt] IN '' " _
                     "'text;database=c:\;FMT=Delimited;HDR=Yes'"
          db.Close
        End Sub

5. Run the project and click the CommandButton to import the data.

6. Examine the contents of the TestImport table and note that the Desc column
  has the leading spaces truncated for Description 1, which did not use quotes,
  but they are present for Description 2, which did use quotes.

Notes:

1. The symptoms are also present when using Access' File|Get External Data menu
  command and via the TransferText macro action and the TransferText method of
  the DoCmd object, all of which use the Text IISAM driver.

2. The symptoms probably also apply to previous versions of Jet but have not
  been tested with them.
