Is Visual Objects a 32/64 bits Compiler ? [Updated 10th March 2009]

I started this thread at comp.lang.clipper.visual-objects

Response by Brian Feldman, Product Owner, Visual Objects &


>>Have Grafx announced any plan for a 64-bits version ?

None. No 64 bit version of VO will be forth coming.

Most of our development efforts are focused on Vulcan.Net, and VO

Vulcan.NET, which is an xBase compiler for .NET based on the "Visual Objects language".

Vulcan.NET produces a .NET exe or .dll. Supports all MS Frameworks. It uses Microsoft Visual Studio 2005 or 2008 as an IDE. An alternative IDE has also been written in Vulcan.NET called VIDE and a trial version is also available for download at the website.

Simply put Vulcan.NET _IS_ xBase for the future.

More info at and free Trial Version at http://www.GoVulcan.NET

A good place to start is to download our 150 page getting started guide:

Comments by Erik & Geof Schaller on same thread as follows :-

1. Vulcan.NET produces a .NET exe or .dll. Supports all MS Frameworks.

The support of the CF is very limited.
With some fiddling you will be able to compile and run an app for the CF,
but you won't have DBF support, no Macrocompiler and also the VO compatible
classlibs will not work on the CF. Also the Vulcan-VS support for CF lacks
interesting features for the CF.

If you consider developing for the CF, you better use one of the MS

Same suggestion for any new development. C# is not that hard at all!


2. Geoff Schaller

As Brian has indicated, there will never be a 64 bit version of VO.
However, any VO or Vulcan app will run perfectly in a 32 or 64 bit
environment so why should it matter? There is very little you would
"need" a 64 bit application for, other than to squeeze a few
milliseconds of performance out, but unless your application needs to
deal routinely with numbers > 4GB I would suggest that 64 bit is largely

And if you need to work with huge numbers routinely, why not go to C# or

Welcome to Clipper... Clipper... Clipper

In 1997, then using Delphi 3, I had already created 32-bits Windows applications for HRIS, ERP and CRM. In 2007, using Ruby on Rails, an AJAX powered CRM site running on Apache & MySQL was created and I am now using Visual Studio .Net 2008 to create web-based projects and Delphi 7 for Win32 applications using SQL2005 & DBFCDX.

So, why then am I reviving the Original Clipper... Clipper... Clipper via a Blog as CA-Clipper is a programming language for the DOS world ? Believe it or not, there are still some clients using my mission-critical CA-Clipper applications for DOS installed in the late 80's and up to the mid 90's. This is testimony to CA-Clipper's robustness as a language :-)

With the widespread introduction of Windows 7 64-bits as the standard O/S for new Windows based PCs & Notebooks, CA-Clipper EXE simply will not work and it has become imperative for Clipper programmers to migrate immediately to Harbour to build 32/64 bits EXEs

Since 28th January 2009, this blog has been read by 134,389 (10/3/11 - 39,277) unique visitors (of which 45,151 (10/3/11 - 13,929) are returning visitors) from 103 countries and 1,574 cities & towns in Europe (37; 764 cities), North America (3; 373 cities) , Central America & Caribeans (6; 13 cities), South America(10; 226 cities), Africa & Middle-East (12; 44 cities) , Asia-Pacific (21; 175 cities). So, obviously Clipper is Alive & Well : -)

TIA & Enjoy ! (10th October 2012, 11:05; 13th November 2015)

Original Welcome Page for Clipper... Clipper... Clipper

This is the original Welcome Page for Clipper... Clipper... Clipper, which I am republishing for historical and sentimental reasons. The only changes that I have made was to fix all the broken links. BTW, the counter from is still working :-)

Welcome to Chee Chong Hwa's Malaysian WWW web site which is dedicated to Clipperheads throughout the world.

This site started out as a teeny-weeny section of Who the heck is Chee Chong Hwa ? and has graduated into a full blown web site of more than 140 pages (actually hundreds of A4 size pages) ! This is due to its growing popularity and tremendous encouragements from visiting Clipperheads from 100 countries worldwide, from North America, Central America, Caribbean, South America, Europe, Middle-East, Africa and Asia-Pacific. Thanx Clipperheads, you all made this happen !

What is Clipper ?

You may ask, what is this Clipper stuff ? Could Clipper be something to do with sailing as it is the name of a very fast sailing American ship in the 19th century ?

Well, Clipper or to be precise, CA-Clipper is the premier PC-Software development tool for DOS. It was first developed by Nantucket Corporation initially as a compiler for dBase3+ programs. Since then, CA-Clipper has evolved away from its x-base roots with the introduction of lexical scoping & pre-defined objects like TBrowse. As at today, the most stable version ofClipper is 5.2e while the latest version, 5.3a was introduced on 21 May 1996.

As at 11th November, 1996, an unofficial 5.3a fixes file was made available by Jo French. See the About CA-Clipper 5.3a section for more details. BTW, Jo French uploaded the revised 5.3a fixes file on 20th November, 1996.

Latest News

The latest news is that CA has finally released the long-awaited 5.3b patch on 21 May, 1997.

For 5.3b users, you must a take a look at Jo French's comments on unfixed bugs in 5.3b.

BTW, have you used Click ? If you're a serious Clipperprogrammer and need an excellent code formatter, Click is a natural choice. How to get it ? Simple, access Phil Barnett's site via my Cool Clipper Sites.

32-bits Clipper for Windows ?

Have you tried Xbase ++ ? Well, I have and compared to Delphi (my current Windows programming tool of choice), I'm still sticking to Delphi.

Anyway, you should visit the Alaska Home Page. Give it a chance and then draw your own conclusions !.
