This is the successor to Clipper... Clipper... Clipper, a popular & well-linked CA-Clipper website which I started in 1995 and which went offline in 2002

Using Harbour+WVG +xMate - Part I
I did consider using WVW but since Budyanto does not have time to update his great GUI library, I decided to take a serious look at Harbour + WVG.
After playing with the xMate that came with Pritpal Bedi's Ready to use Harbour Distro, I finally managed to compile and build a Harbour+WVG version of FAS4DOS codenamed FAS4WVG. This is what I have done :-
1. Installed Pritpal's Ready to Use Harbour which resulted in a folder being created ie
c:\harbour_dev with the following sub-folders
dev_exes
dev_libs
dev_projects
dev_sources
harbour
mingw
xmate
2. I then copied the previously converted FAS4DOS codes (from 5.2e to xHarbour) into a new folder FAS4WVG under the dev_projects folder. I did this in order to save time as all UNRESOLVED EXTERNALS had already been dealt with as per my previous articles "Migrating from CA-Clipper 5.2e to xHarbour Part I, II & III "
Please note that there is also a default demowvg folder already there for your reference.
3. Moving to the xMate Directory, I launched xMate and created a new Project
4. What is important here is to choose
a) Project Type, default Executable
b) Environment (wvgMINGW, wvgBCC, wvgMSC, wvgWATCOM)
Nb. Only MINGW comes with this Pritpal's Distro
c) You may also choose to Import based on a Clipper Blinker/Exospace link script
5. Click OK and
a) Input Project name, in my case FAS4WVG
b) Input HOME Folder (where your project files reside)
c) Add Project Files
c) Save and both the XMate Editor and Project Manager are launched
6. Under the xMate Project Manager, you can choose to :-
a) Build Project
b) Build and Launch Project
c) Rebuild Project
d) Rebuild and Launch Project
e) Launch Project
f) Compile single source
g) Compile all sources
7. I then clicked (b) and starting getting errors mainly due to ambiguous references relating to getlists which I resolved by adding LOCAL getlist:={}
8. Then, I got the 'FATAL : Unknown Error - Check Output Console'
9. I then clicked the icon that had a ? over it and saw that I had a few errors such as
a) Unresolved external references
b) Duplicate decalarations
By checking to my original Blinker Link Script, I realised that I had inadvertently left out a prg whilst including a couple of redundant prgs.
10. Once resolved , bingo, FAS4WVG was finally built and launched
Next to add GUI features ...
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 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 !.

Hi CCH,
ReplyDeleteThis will be extremely helpful to all clipper programmers (like myself)! I downloaded Pritpal's WVG and installed it.
I already used xMate and I like it very much. Now, from Pritpal's setup I got the .env files. Only problem is that black background color!!!! Frankly speaking I don't like it. So I have to customize it.
Regards.

I'm really eagger to see more of your work. I have the same type of clients that hate mouse work, and I'm really looking for a solution for providing graphic interface without windows dependency...
ReplyDeleteI don't know if I should loose hope on the future release of LLIBG xHarbour port...
Maybe this is a good alternative.
Good job
Hi CCH
ReplyDeleteI want to develop a Harbour WVT application with similar look to FAS4WVG. I'm new to Harbour/GT and need real application source code to study. Could you please provide my the source code for FAS.
Thank you and best regards
