Hello Richard,
welcome at Jabaco.
I do not know a special tutorial for Jabaco. I mean you must collect your information from different sources.
The language and the IDE is very near by Visual Basic. So look e.g. at
http://www.vb6.us/ for samples and tutorials, the most of them work with Jabaco, but not the specials, e.g. ActiveX. Or look at
http://www.vbtutor.net/vbtutor.html or
http://www.garybeene.com/vb/tutor.htm.
The symbiosis from VB and Java is combined in Jabaco. So it is important, beside language and syntax, to have knowledge about the Java object model. Load from
http://java.sun.com/javase/downloads/index.jsp the Java SE 6 documentation.
I think with this information you get a very good base to be an expert programmer in the near future.
And last but not least you have the possibility to ask this forum, your questions are welcome.
Cheers
Stefan
