ActiveVFP Project - Foxpro on the World Wide Web
PHP or MVC style, you choose. VFP pages or VFP controller - just add Fox code!!
AVFP- best choice for using FoxPro with REST as a RESTful server. AVFP- best choice for using FoxPro with Android, iPad, iPhone.
ActiveVFP 6.03 Demo onGoDaddy Shared Hosting.
ActiveVFP 6.03 Demo on local network.
Easily installs on local IIS, GoDaddy, Arvixe, WinHost, Discount ASP.NET, SoftSys, many others. Get the cheapest web hosting rates ($5/month and below) using AVFP. Don't pay a premium just for using FoxPro!
FoxPro to Web, FoxPro to Mobile, FoxPro to Cloud: ActiveVFP(AVFP) is a completely free and open source project for creating web applications with the Visual Foxpro programming language and database (and other DBs like MSSQL or MySQL). It provides an easy-to-use framework in pure fox code for utilizing a multi-threaded vfp dll (vfp mtdll) called from ASP.NET. If you're considering web programming with FoxPro, using FoxPro in the cloud, or converting desktop VFP to web or mobile - using Android, iPhone, or iPad, this tool is for you.
Free and open source web software for the Foxpro community!!!
Faster than PHP on Windows, easier than C#!
Windows Web Scripting Comparison for AVFP vs. PHP vs. ASP.NET Razor
Really multi-threaded, really runs in the cloud, really open-source - accept no substitute! The goal of this project was to match or surpass the capabilities of commercial vfp web development products and to take vfp into the future by making it easy to interop with .NET for web applications. Along with this, ActiveVFP makes using cool web and mobile technologies like JavaScript, AJAX, JSON, jQuery, jQuery Mobile, AngularJS, Bootstrap, HTML5, CSS, PDF, Android, iPhone, iPad, RESTful web services (and more!) with FoxPro a breeze.
Fastest and most scalable VFP web solution, yet also the easiest to setup and program!
"...It can do everything the commercial vfp web products can and more like the ability to be easily hosted atcheap shared web hosts like
GoDaddy
, XCOPY deployment, and true
multi-threading. I think of it as applying more modern technology to foxpro web development as compared to most of the older products that were developed 20 years ago and still use the original outdated techniques. However, AVFP is extremely easy
to use and develop in." -VFP Developer. No more paying for the privilege of using outdated technology!
High Availability, High Performance, works with Everything! Unlike commercial VFP web products, ActiveVFP concentrates on producing multi-threaded COM VFP server apps. While commercial VFP web products all have a multi-threaded ISAPI
client (as does ActiveVFP), only ActiveVFP focuses on creating multi-threaded VFP web server applications using a vfp mtdll. No simulated multi-threading (using multiple VFP EXE processes) here. What this means for you is much faster, efficient and scalable
vfp web applications along with far less maintenance headaches and worries about uptime. It also means you take full advantage of new Dual-Core, Quad-Core or multiple processors in new computers increasingly available now.
Your ideas and code contributions to this project are always welcome. Guidance for enhancements to ActiveVFP is on theIssue Tracker page.
Making it easy to use Foxpro on the web!!

VFP COM Debugging
From
Microsoft Visual Foxpro FAQ:
"Q: Can I use Visual FoxPro to build Web applications?
Visual FoxPro COM components can be used with Internet Information Services (IIS) to build high-powered Internet database applications. This is because Visual FoxPro components can be called from Active Server Pages (ASP). Visual FoxPro is compatible with ASP
but works even better in conjunction with the more modern ASP.NET. The components will retrieve and manipulate data, and will build some of the HTML returned to the user. "
Notable Quotes
"I was able to get a mobile site using AVFP up and
running in about 30 minutes." Andrew MacNeill, Akselsoft
On running ActiveVFP at
GoDaddy, "I got it working and I tell
you its sweet" LarryJ
"Everything you see is completely controlled by VFP code. Data controlled pictures, text, links,
and calculations are 100% VFP. I can change anything on the fly and it is multiuser right out of the box."
"...The dealership has a server guy who didn't know it was a VFP application. He was bad mouthing VFP for being old and slow. He was glad my new Super Fast application was built on .NET and used SQL server backend. I let him ramble on, then told him that it
was powered by VFP and used DBF tables. He told me "There is no way, a Foxpro application with that much data would be terribly slow." I just laughed and simply told him that any *Decent* Programmer can make VFP fly. I am still chuckling. He was so sure it
was .NET with SQL. He had to admit it was extemely fast." Don Higgins, Crew Chief Pro Software
"You should not have an issue with performance if you use multi-threaded
DLLs. I regularly test Visual FoxPro COM DLLs by simulating 40 clients
pounding the server for days at a time, generating as many as 3 million hits
per day (on a four-proc machine with 2Gb of RAM and striped RAID). If you're
site is generating more hits per day than that, I think other stuff is going
to break down before your COM servers. :-)" Mike Stewart, Microsoft
"I installed AVFP 5.5 experimentally this morning: xcopy the app and support libs to a
Windows 2003 server,create a new IIS virtual directory, map it to the new folder,
allow scripts and execute, I also created a new application pool out of habit...
then hit the site and the VFP app was serving pages. No DCOM, no registration,
nothing else to configure..."
"..Just for the record for people who haven't tried it, we're using an ActiveVFP MTDLL
in a production environment at the moment. That thing is fast- quick enough that it's
the server and network latency causing the biggest bottlenecks. We're talking a 15Mbps
connection burstable to 100Mbps so the app itself is doing fine." Jack Ryan

Use
<META http-equiv=Content-Type content="text/html; charset=windows-1252">
instead of
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
This solves the squiggly character() problem at the top of the page. You may have to start with a completely new page if those characters are already in the document.

General notes:
For a Software as Service (SaaS) running on a web host serving multiple clients,
we'd use this sort of PDF generation. PDFs will work in this application either
remotely or locally (if the app is run on the local LAN)
As an alternative, if this application is running in-house on the local LAN, we
can also generate the VFP report directly to the printer without need for PDF
Demonstrates:
- use of theme which can be swapped for others
- new built in PDF generator that can run at shared web hosts like Arvixe
- Responsive design: works as is on web and mobile. same code base

All server-side is VFP code. Existing VFP code can be used.:-
NOA Report Form View (noaReportView.avfp). At the start of the view I use
VFP code to open some tables and prepare data to be shown in the form. This
code was copied from Init method of Action2014.scx file. -
Some of this same Init method code was used to set pre-report code in
denialReport() method on the NOA REST controller. -
Denial NOA report (denialaction2014-1.frx) was reused as it was. The only
change I made was to exclude the Printer Environment. In fact, the idea for the
conversion project is to reuse ALL his report formats as they are, without
changing anything.

New Post: Modern web\mobile development with ActiveVFP example!
This was a Proof Of Concept we made for a potential customer looking for converting his VFP Desktop App to a web app. The idea was to reuse as much of the original code as possible.
For this, the customer sent us a report format and the code to prepare that report, taken from his actual app. With this, we created a Single Page Applicaation, using a metro theme. We also used GridForms to create a data entry view and used REST controllers to receive the form data, save it to a DBF file and then call the original FRX report with no changes at all. The output of the report was saved as PDF and returned to the browser for its display on screen.
This probed that although ActiveVFP will require to rebuild the whole UI of your application, it its actually possible to reuse all your biz code and all your reports with minimum effort.
Also, this sample use some of the new features that will be included in the next release of ActiveVFP, including:
1) MVC REST service
2) Built-in reporting and PDF exporting
3) New built-in fast JSON parser
4) New bult-in functions

i have a random problem with pdfrun. I use it for make a pdf from report at end of my procedure. It works fine but randomly he stop to work and show me error on wrong identity or invalid username and password.
I release the object "oPDF" every time. I can solve the problem only with IIS restart.
Do you have a idea?

Hi Victor,
One question on the demo website regarding the report generation. What will happen if the workstation trying to view the report doesn't have an acrobat or a PDF viewer installed?

Seemingly all the browsers have built-in PDF viewing\printing support except IE. If there's nothing to bring up the PDF with, I'm assuming it will prompt you in some way to install a PDF viewer.

We have some fallback options:
1) As claude suggested, we could redirect the user to an specific error page instructing him to install Adobe Reader to preview reports. This page could also contains a link to download the generated PDF.
2) A variant of the error page could be to show a warning inside the preview area pointing out that PDF preview is not available, with instructions on how to install Adobe Reader and a link to download de generated report.
3) We can redirect the user to an external PDF previewer service, like Google Docs or something link that.
My choice would be 2).

I read an old topic and i've tried the way to use "computer account" instead "interactive user" but the browser tell me, always, unknown error. Only with "interactive user"mode it works but with error if i reuse it in the same times (1 or 2 minutes later).

Hi Victor,At this time the demo check if the browser is a mobile browser or doesn't have any PDF plugin installed. If either of this conditions results true, the demo opens the PDF file in a new browser window. In mobile browsers this results in the PDF being shown in screen. In IE it results in the file being download (I am not really sure about this one).

Here you can find the documentation of AVFP: Click here, and here you can see many examples: Click here.
There isn't a tutorial step-by-step because is necessary to know Visual FoxPro and the base Web Development.

You can find an older version of the docs online here
and, as mr. ocean said, the online demo shows the source code with the examples. You get the same thing on your computer when you download the software.
The most current docs will be up soon. I'm transitioning web sites (GoDaddy will give me free Windows Plesk hosting for a year!) and I'll put everything there along with the new version of AVFP demos.
