This is a series of books I started writing back in 2012-13 and is on the Gambas wiki.
Sholzy hosted them back in the day on a, now no longer available website/forum for gambas, for download.
The end of WhiteIslands Software forum gave birth to Gambas One…

Guess what, I stumbled upon de pfd's I made in that time and shared them on Dropbox.
I have updated the links on the Gambas wiki. It takes a day for all to update on the wiki, so they should be there tomorrow (https://gambaswiki.org/wiki/doc/book)

The first book on installing Gambas is from when Gambas was still on svn and of no use other than historical value on how stuff was done back in the day.
The second book is still very useful for those new to Gambas and programming in general, as all is about basic stuff that hasn't changed over time.

How to Gambas - Building GUI applications 0.0.1

As it has been very long ago and that what I had in mind for doing is long gone, I will probably not continue writing the end.
Hope it will be useful to those in need of more material on Gambas3 as is.

Edit: I added the link here to the most useful of the 2

I came across this the other day…

…and was wondering if you were still creating them.

I might still have the full site hiding in some dark corner of my hard drive.
