Steps to Reproduce Behavior

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

         ID,Desc,Field3
         Line1,Description 1  ,Field3-1
         Line2,"Description 2  ",Field3-2
   						

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 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/form and click the CommandButton to import the data.
6. Examine the contents of the TestImport table, and note that the Desc column has the trailing spaces truncated for both records.

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.
3. In Visual Basic, you can use the VISDATA sample project to examine the contents of the table.
