To create a folder of Internet shortcuts from a field of hyperlinks, follow these steps:

1. In Windows Explorer, create the following folder:

   C:\MyShortcuts

2. Start Access 2000, open a database, and create the following table:

      Table: tblHyperlinks
      -----------------------
      Field Name: fldLink
      Data Type: Hyperlink
   					

3. Save the table as tblHyperlinks. When prompted to create a primary key, click Yes.
4. Switch to Datasheet View, and type a valid Internet address into the fldLink field of the first record.
5. Right-click the address, point to Hyperlink, and type a descriptive name in the Display Text box. Although the displaytext portion of the Hyperlink data type is optional, you can hide the URL address and display a more user-friendly name for the hyperlink if you specify display text.
6. Repeat steps 4 and 5 until you have added several records with different Internet addresses.
7. Create a new module and type or paste the following code:

   Sub ProcessHyperlinkTable(strTableName As String, _
      strFieldName As String)
   
      ' Declare variables.
      Dim DBS As DAO.Database
      Dim RST As DAO.Recordset
      Dim strSQL As String
      Dim strAddress As String
      Dim strDisplayText As String
      Dim strDirectoryPath As String
      Dim varLink As Variant
   
      ' Set error trapping.
      On Error GoTo Error_handler
   
      ' Assign the current database to the database variable.
      Set DBS = CurrentDb
   
      ' Set the path to the existing directory
      ' where the shortcuts will be created.
      ' Note: the path should end with a backslash ("\").
      strDirectoryPath = "c:\MyShortcuts\"
   
      ' Set the SQL string to return the field
      ' containing the hyperlinks from the
      ' table you have specified.
      strSQL = "SELECT " & strFieldName _
         & " FROM " & strTableName
   
      ' Open the Recordset.
      Set RST = DBS.OpenRecordset(strSQL)
   
      ' Move to the first record.
      RST.MoveFirst
   
      ' Loop until reaching the end of the table.
      Do Until RST.EOF
         ' Check to see if the HomePage field contains a link.
         If Not IsNull(RST!fldLink) Then
   
            ' Set varLink equal to the current Hypertext link field.
            varLink = RST!fldLink
   
            ' Pull the Address from varLink.
            strAddress = HyperlinkPart(varLink, acAddress)
   
            ' Pull the display text, if any, from varLink.
            strDisplayText = HyperlinkPart(varLink, acDisplayText)
   
            ' If there is no display text, set strDisplayText to
            ' be the same as the URL.
            If strDisplayText = "" Then
   
               ' If strAddress starts with "Http://",
               ' or "Ftp://", leave that out of strDisplayText.
               If Left(strAddress, 7) = "Http://" Or _
                  Left(strAddress, 6) = "Ftp://" Then
   
                     strDisplayText = Right(strAddress, _
                        Len(strAddress) _
                        - (InStr(1, strAddress, "/") + 1))
               Else
               ' Otherwise, simply set strDisplayText
               ' equal to strAddress.
                  strDisplayText = strAddress
               End If
