Using Harbour+WVG +xMate - Part IV - CONCLUSION

From Part III of this series of articles, this is what I have achieved thus far.

How about adding features to the Console Window itself ?

This is how you change the caption and application icon :-

//This ensures that window is physically existent when any operation on console are requested.

// Add icon
hb_gtInfo( HB_GTI_ICONFILE, "ksred.ico" )

// Add Window Caption
hb_gtInfo( HB_GTI_WINTITLE, "FAS4WVG - Clipper... Clipper... Clipper" )

Is there a GUI Alert() that is fully compatible with CA-Clipper Alert() ?

Why not, with Pritpal's excellent programming skills, ALERT("Reindex ALL Files ?, {"No","Yes"}) gives you this Windows Dialog :-

Isn't this what you would have expected ?

Please note that the GUI Alert() available in the April 2009 Edition of distro simply maps to MessageBox with OK as the only option. So if your code is nChoice:=ALERT("Reindex ALL Files ?, {"No","Yes"}), Pressing OK will never Reindex !

You will have no such issue with Pritpal's Harbour Ready to use Distro.

Actual Reindexing in action ...

The above was achieved using wvg_BoxRaised(), wvg_BoxRecessed() and wvgBoxGroupRaised().


To quote Pritpal from one of of his email response

" GTWVG is meant to update your Clipper code to have Windows look and
feel without any code changes, just addition of few lines. If it were to mimick exact
GUI behavior then there are many other options, but you end up writing practically
everything, which is simply difficult if not impossible.

This is a matter of focus. "

What do we wish to achieve for our keyboard-loving customers ?

Well, we need to break the DOS barriers and avoid the need for the customers to be retrained in their daily usage of their mission-critical applications.

So, if you wish to avoid lots of re-programming your Clipper Codes and only want to provide your keyboard-loving customers with a simple GUI but clearly 32-bits Windows solution, IMHO, Pritpal's Harbour Ready to Use Distro that includes Harbour +WVG +xMate is the way to go...

If your needs are more onerous, may I suggest HMG or HMG Extended ?

Good Luck !

BTW, this is the final part of Using Harbour+WVG +xMate but I will continue to write on my experience with Harbour Ready to Use + GTWVG aka WVG


  1. "Please note that the GUI Alert() available in the April 2009 Edition of distro simply maps to MessageBox with OK as the only option. So if your code is nChoice:=ALERT("Reindex ALL Files ?, {"No","Yes"}), Pressing OK will never Reindex !"

    This information is not correct. I use Alert() a lot in visual xharbour and it behaves as in CA-Clipper.

  2. Hi Claude

    I know that the Text Alert() works correctly, I am referring to the GUI Alert() that you get when you add winapi.lib

    You should also refer to my posts plus other similar posts on comp.lang.xharbour and on the xHarbour Builder NG.

    This is a feature that I have been asking for since 2006 and Ron Pinkas and Patrick Mast has been saying.. "We'll look into it" and Patrick has recently confirmed that the Clipper-compatible GUI Alert() is NOT available even in the April 2009 Edition of the distro :-(

    Best Regards


  3. Hi Claude

    Yes, the GUI Alert() works in VXH but I do not use VXH.




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 !.
