Power for your Internet Server

Who Am I
 Mike Feltman
 President F1 Technologies since
1990
 Co-designer & author of Visual
FoxExpress framework
 North American AFP Distributor
 “.NET Project Rescue Specialist”

Agenda
 What is AFP?
 Why AFP?
 Creating an AFP Site
 Getting Started with Simple Pages
 Separating code from layout
 AFP Application Architecture
 The AFP ControlCenter
 Debugging
 AFP Versions
 Where and how to get AFP

What is AFP?
 Active FoxPro Pages
 ISAPI Extension
 ASP work alike using VFP code
instead of VB Script or Java Script
 Optional ASP.NET like separation of
code from layout
 Complete OOP support

Why AFP?
 VFP Language  Leverage VFP
 Stable skills on the
Internet
 Fast
 Secure
 Use your existing
classes
 Easy
 Take advantage of
 Extensible VFP performance
 Hassle-Free  Integrate with
desktop apps

Why AFP?
 VFP Language  High performance
 Stable and stability for
mission critical
 Fast
environments
 Secure
 Support for
 Easy clustering and
 Extensible high-availability
 Hassle-Free web sites.

Why AFP?
 VFP Language  Based on VFP
 Stable  Multi-threaded
 Fast without requiring
 Secure MTDLLs
 Easy
 Automatically
compiles pages
 Extensible
 Handles millions of
 Hassle-Free hits per day
 No Slow COM calls
 No need for ODBC,
ADO or OLEDB

Why AFP?
 VFP Language  No files stored in
 Stable wwwRoot
 Fast  Code is not visible
 Secure to the client
 Easy
 Automatic session
management
 Extensible
 Support for HTTPS
 Hassle-Free
 Integrates with
Windows security

Why AFP?
 VFP Language  VFP Syntax
 Stable  ASP like Object
 Fast Model
 Secure  Use any web
 Easy development tool,
VFP or Notepad
 Extensible
 Use VFP’s
 Hassle-Free debugging
capabilities
 No need to start
and stop IIS

Why AFP?
 VFP Language  Use your own or 3rd
 Stable party VFP classes
 Fast  Use VFP’s COM
 Secure support
 Easy
 Anything goes with
plug-ins
 Extensible
 Hassle-Free

Why AFP?
 VFP Language  Easy installation
 Stable and configuration
 Fast  Works with any
 Secure ISAPI compatible
web server (IIS,
 Easy Apache, etc.)
 Extensible
 Hassle-Free

Creating an AFP Site
 Option 1
 Create a folder in InetpubwwwRoot
 Option 2
 Create a folder anywhere
 Enable web sharing

 That’s It!

Creating Simple Pages
helloworld.afp
 Create a new file in notepad with the
following text
<html>
<body>
<% ? "Hello World" %>
</body>
</html>
 Save it as helloworld.afp
 Navigate to it in your browser at
http://localhost/afpdemo/helloworld.af
p

listcustomers.afp
 Create a new file in notepad with the following text
<html>
<title>AFP Customer List</title>
<body>
<%
USE (_SAMPLES + [DATACUSTOMER])
SCAN
? Company
? [<br>]
ENDSCAN
%>
</body>
</html>
 Save it as listcustomers.afp
 Navigate to it in your browser at
http://localhost/afpdemo/listcustomers.afp

 Additional Pages
 ListCustomersXML.AFP
 Menu.AFP
 ViewSource.AFP

 ProLib Samples
 Sprechen Sie Deutsch?

Code Separation
 Programming 101 – Separate Form
from Functionality
 Not well supported in classic .ASP
 Supported in ASP.NET
 .Code file with the same name as
the .AFP file can contain VFP code
for the page. (test.afp code file =
test.afp.code)

Separating Code From Layout
 Samples
 CustomerList2.afp and
CustomerList2.afp.code
 Customer.afp and
Customer.afp.code

AFP Application Architecture
 All of the .AFP files in a directory
 Requires an Application Id in .AFPA file
<application ID=“???"/>
 Files in directories other than the
application root can be made part of an
application
 Common Code can be stored in
.AFPA.Code File
 Functions
 Class Definitions
 Events

AFP Demo Application Files
 AFPDemo.afpa
 AFPDemo.afpa.code
 CustomerTable.afp

The AFP ControlCenter
 Displays Status for each Instance
 Allows Configuration Modification
 Send Requests to AFP without going
through Web Server

Debugging
 DEBUG, SUSPEND, SET STEP ON
& ASSERT are supported
 DO AFP3Debug.prg
 Use regular VFP debugger
 Can also use ALF+F5 to open the
debugger
 Remember to exit “debug mode” with
SHIFT+F5

AFP Versions
 AFP Professional  AFP Express
 $499 US  $99 US
 Supports up to 3  Supports only a
host names single host name
 Cluster support  No cluster support
 Multiple server and  No plug-ins
unlimited server  Limited debugging
licenses available support

Review
 Key Features:
 VFP Language
 Stable
 Fast
 Secure
 Easy
 Extensible
 Scalable
 Complete debug support
 Programming models:
 Script within HTML pages
 .Code files associated with pages
 VCX, PRG classes
 Application level code in .AFPA.Code Files
