SUMMARY
=======

Hyperlink functionality is a new feature available in Visual FoxPro 6.0. Using a
hyperlink object, Visual FoxPro applications can be used to request an Active
Document container or to navigate to a given Uniform Resource Locator (URL).
This article describes how to use hyperlink objects to launch a Web browser when
the object is clicked.

MORE INFORMATION
================

A Hyperlink object does not have a user interface and is supported only in
Microsoft Internet Explorer. The Hyperlink Button, Hyperlink Image, and
Hyperlink Label Foundation Classes in the Component Gallery, however, can be
used to create browser independent navigational capabilities.

The cTarget property of a Hyperlink object is used to specify the URL for the
object. The lnewwindow property of a Hyperlink object is used to determine
whether a new instance of the Web Browser is created when the object is
clicked.

The following code example illustrates use of the Hyperlink Button, Hyperlink
Image, and Hyperlink Label objects.

Sample Code
-----------

1. Create a program called Testlink.prg, using the following code:

         * Begin Code
         CLOSE ALL
         SET CLASSLIB TO home()+"ffc\_hyperlink.vcx"
         ohyperlinkobject=CREATEOBJECT('hyperform')
         ohyperlinkobject.SHOW
         READ EVENTS

         DEFINE CLASS hyperform AS FORM
            TOP           = 0
            LEFT          = 0
            HEIGHT        = 100
            WIDTH         = 385
            DOCREATE      = .T.
            CAPTION       = "Use of the Hyperlink Class"
            NAME          = "Form1"
            SHOWTIPS      = .T.

            ADD OBJECT _hyperlinklabel1 AS _hyperlinklabel WITH ;
               LEFT       = 25, ;
               TOP        = 10, ;
               HEIGHT     = 25, ;
               VISIBLE    = .T., ;
               FONTNAME   = "Times New Roman", ;
               FONTSIZE   = 14, ;
               FONTITALIC = .T., ;
               AUTOSIZE   = .T., ;
               ctarget    = "WWW.MICROSOFT.COM/VFOXPRO", ;
               CAPTION    = "FoxPro", ;
               lnewwindow = .T., ;
               NAME       = "_HYPERLINKLABEL1"

            ADD OBJECT _hyperlinkcommandbutton1 AS _hyperlinkcommandbutton
              WITH ;
               LEFT       = 25, ;
               TOP        = 50, ;
               HEIGHT     = 25, ;
               FONTNAME   = "MS Sans Serif", ;
               FONTSIZE   = 12, ;
               VISIBLE    = .T., ;
               ctarget    = "WWW.MICROSOFT.COM", ;
               CAPTION    = "Microsoft", ;
               lnewwindow = .F., ;
               NAME       = "_HYPERLINKCOMMANDBUTTON1"

            ADD OBJECT _hyperlinkimage1 AS _hyperlinkimage WITH ;
               LEFT       = 200, ;
               TOP        = 0, ;
               VISIBLE    = .T., ;
               ctarget    = "WWW.MICROSOFT.COM/VFOXPRO", ;
               PICTURE    = home(4)+"\BITMAPS\TLBR_W95\PROP.BMP", ;
               STRETCH    = 2, ;
               HEIGHT     = 50, ;
               WIDTH      = 50, ;
               lnewwindow = .T., ;
               NAME       = "_HYPERLINKIMAGE1"

            ADD OBJECT command1 AS COMMANDBUTTON WITH ;
               LEFT       =200, ;
               HEIGHT     =25, ;
               CAPTION    ="Clear Form", ;
               TOP        =60, ;
               WIDTH      =100, ;
               NAME       = "Command1", ;
               TOOLTIPTEXT= "Close this form"

            PROCEDURE command1.CLICK
               CLEAR EVENTS
            ENDPROC

         ENDDEFINE
         * End Code

2. In the Command window type the following:

         DO TESTLINK

3. Click the label, captioned "FoxPro", to launch an instance of the default Web
   browser and navigate to the URL specified with the cTarget property.

4. Click the Command button, captioned "Microsoft", to navigate to the URL
   specified with the cTarget property without launching a new instance of the
   Web browser.

5. Click the Hyperlink Image to launch an instance of the default Web browser
   and navigate to the URL specified with the cTarget property.
