SUMMARY
This article shows you how to create sample Visual Basic for Applications code that creates Internet shortcuts from a Microsoft Access table that has a Hyperlink field with one or many records. The shortcuts are then placed in a folder on your hard disk.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. To create a folder of Internet shortcuts from a field of hyperlinks, follow these steps:  In Windows Explorer, create the following folder:

C:\MyShortcuts

  Start Access 2000, open a database, and create the following table:   Table: tblHyperlinks ---  Field Name: fldLink Data Type: Hyperlink  Save the table as tblHyperlinks. When prompted to create a primary key, click Yes. Switch to Datasheet View, and type a valid Internet address into the fldLink field of the first record. 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. Repeat steps 4 and 5 until you have added several records with different Internet addresses.</li>  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

End If

' Pass the URL, the link name, and the directory path to        ' the function. Create_Hyperlink_Shortcut strAddress, strDisplayText, _ strDirectoryPath

End If

' Move to the next record. RST.MoveNext
