Even off-topic, I understand what you are saying about the xChart library, the same for the xGraph library.
If there is an interest, I could provide more detailed explanations.
But how deep to go into it for how many users ?

Anyway, when I try to make charts in Excel it is also not that evident, at least for me. Well, yes, this is not an excuse!

@klaus

There is a unlucky typo in B4XGettingStartedV2_1.pdf, Page 114 chapter 5.12.1.2

Note: File.Exists does not work with Dile.DirAssets !!!

It should be File.DirAssets.

As I have an actual issue in a test app exactly with this typo it hit me in my beginner face
When I search for File.DirAssets in my PDF reader I can not find this information.

klaus · Mar 20, 2021

Thank you for reporting this typo, it is amended for next edition.
The typo was in the Basic language booklet.

Hello guys, I'm compiling a book about B4X for Portuguese and Spanish language. My chinese is not good, but I can try to translate it into Chinese too (@K_Kai).
When i´ve more news, let you knows.
I wnat to send to Erel and Klaus first to be approved.

klaus · Mar 27, 2021

For me no problem, you can use all the content of the booklets and the source code.
You may also have a look at THIS answer.
The Word files of the booklets can be found here: https://github.com/AnywhereSoftware/B4X_Documentation
I just checked them, they are edition 1.9, the latest edition is 2.1.
Maybe Erel could update the them.

User @Genival Carvalho intended to translate the booklets to Portuguese (Brazil) language, I do not know if he did it.

Erel · Mar 28, 2021

I've uploaded the latest versions.

Sabotto · Apr 22, 2021

I report this small bug in the file "B4XVisualDesignerV2_1.pdf" inside the B4A Booklets (guide) On page 16, the link to go to the "Designer Scripts" page leads to page 67 (Anchors) instead of page 80 (Designer Scripts). It is not important, but maybe in the next update it can be corrected. It is only an indication

klaus · Apr 22, 2021

Thank you for reporting this.
Amended for the next edition.

Also on p. 36 the text "Guide \ SourceCode \ TestLayoutsAnchors directory" must be replaced with "GettingStarted \ SourceCode \ TestLayoutsAnchors directory"

klaus · Apr 22, 2021

Thank you again.
Also amended for the next edition.

Could you, please, also update to version 2.2 the Word documents in https://github.com/AnywhereSoftware/B4X_Documentation ?

Erel · Nov 14, 2021

Done.

Dear Klaus,
I owe at least 70% of my B4X wisdom to your booklets and help, 28% to Erel and the forum and < 2% to intuition. Thank you all for your support and bearing with my sometimes stupid or boring questions.

As advocate of the well-behaved document (you can google this term) I must say that your booklets are great in that they have meaningful titles and very practical bookmarks for easy navigation. Unfortunately they contain no other metadata (keywords) which would allow them to be automatically indexed on the fly in my digi-libris personal knowledge base (PC, Mac and B4A). Thus I have to index the whole collection again every time in Acrobat.

Best regards, john m.

klaus · Dec 1, 2021

I need to look at this more deeply.

klaus · Dec 3, 2021

I had a look at some sites.
Sorry, but I do not really understand what kind of information should be added nor where and how.
From what I have seen, it seems that they should be added in the pdf files.
The booklets are written with Word and the pdf files are generated from within Word.
I suppost that this would mean that every time a pdf file is generated the information must be added afterwords.
I am not sure that many B4X users are interested in.

johnmie · Dec 3, 2021

In Word click on File -> Info and under Properties click on show all. There is a field for the Subject and Keywords can be listed under Tags. These metadata are automatically save to the PDF, no need to add afterwards.

BTW B4X users are all computer savvy. The digi-libris project was developed for less knowledgeable people using mobile phones in areas with poor Internet connection and who regularly download and incrementally refresh learning material of different types from multiple sources.
Of interest to B4X users could be some of the techniques I've developed to extract metadata, not only from PDF but also from pictures and videos, to manually add metadata for search purposes, to build complete libraries for distribution on CD (outdated by now) and even to show scrolling translations of videos. But this was 3 years ago. Google no longer lists the app for "security" reasons.

klaus · Dec 3, 2021

OK, but what kind of information would you like to be added there ?

I noticed, so it all seems a bit pointless without the app being available.
