All files are included in the zip file in the link above, pdf booklets and all the source code.

You can also download all the source code for al booklets, SourceCode.

These booklets cover the four B4X platforms.
Some don't cover B4R because the subject is not relevant for B4R like Visual Designer.

Example projects with source code are included.

All booklets can be accessed online with the links below.
The generic link is: https://www.b4x.com/guides/BookletName/?page=xx

The booklet names must begin with B4x (the x is in lower case) and without blank characters.
The summary of the list can be found here: Documentation

The B4X Booklets have been updated to edition 1.9, details in post#1.
A new B4XPages Cross-platform projects booklet has replaced the previous Cross-platform projects booklet.

Hello Klaus,

thank you for the new B4XPages Booklet.

I am focussing on cross platform development. As a beginner within B4X I started with the previous version. With new version it is easier to do cross platform development.

I have some feedback.

Chapter 6.4.1 Code of B4XMainPage
Code is missing for
- FillComboBox
- btnPage1_Click
- xcbxMainPage_SelectedIndexChanged

Same for 6.4.2 Code of B4XPage1.

I checked the example project. There I could find the code.

Layout / Format Booklet
The head of the pages has the same size as the text from a page. As a reader this is a bit disturbing. Is it possible to make the head of a page with a smaller font and maybe a line so it is better to read.

I have also some feedback for the example code. Is this the right place or in another thread?

Best regards

--Christian

 

[klaus]

Thank you for the feedback !

The code has been added for the next edition.

For the header, i will look at it.

For the other feedback you can PM me.

Klaus,

It looks like you've done a great job yet again even though I've only had time to skim.
From the point of view as the Lowest Common Denominator the only comment I can make is that the suggestion re: the page headers is probably a good one. Not that there is really a problem but looking at other documentation I see the point.

Regards Roger

Its perfect.
Thanks a lot.

I didn't find information about the Booklets license.

What can I do with Booklets and source codes?
Can I distribute, adapt and sell?
Are the license terms expressly written somewhere?

 

[Cableguy]

This is my opinion and the way i see the booklets, not Klaus's!
The booklet were introduced by Klaus to help newcomers better jump-start in b4x.
Along the way, source code for common issues or questions were added, and samples on how a particular feature works or should be better implemented.
A few gems are also there, like smarter ways to use some feature or a "magical" code for a not so obvious use.
All this is Klaus work, and although i guess he won't oppose to any usage of it, the minimum one can do to honor his work is to credit him on our final product, if he has helped, directly or even indirectly, in the creation of such product.

Again, this is my opinion and how i see the booklets usage.

I agree. The work is brilliant but we must always know clearly what the license terms. We must know what we can and cannot do. Where it is written. If we should credit the author and how we should do it.

The Books are written by Klaus. Copyright is at the Author.
Anything you do to resell the Documents copyrighted by anyone must be Approved and permitted by the Author.

Bottomline:
As long as you do not have the written permission (email for ex) from the Copyright-Owner (Author) you are not allowed to resell anything. Freely available for download or not.

PS: I´m not a lawyer though....

Klaus and myself have decided to make the guides open source: https://github.com/AnywhereSoftware/B4X_Documentation

Give attribution to Klaus and do whatever you like with it. I'm always happy to see more B4X guides in any form (free or non-free).

 

[klaus]

I confirm Erels answer, you can do whatever you want with the booklets content and the code examples.

Thank you @Erel and @klaus. I am building a site about arduino in my native language. I will use b4x for the projects. My website will sell components and sensors. It is a very modest project. Booklets will be very useful.

[SimonAndroid]

Thanks

[johnmie]

Fantastic (as usual with Klaus). You saved me a lot of time and a ton of headaches.Thank you very much.
I also saw recently your update on xChart which included a Radar chart. Very interesting, do you also have this covered somewhere?

Best, john m.

 

[klaus]

Very interesting, do you also have this covered somewhere?

No it is not covered somewhere, I thought and expected that the in-line help and the demo program is enough self explanatory.
But it seems no, I agree, it has become a big library and could be somewhat difficult for 'new' users.

 

[Peter Simpson]

I thought and expected that the in-line help and the demo program is enough self explanatory.

I tend to agree with you about that, especially as you've created the demo app which includes demo code for each and every single chart available in xChart.

I will admit that parts of the demo program could be made slightly simpler to follow (code wise) and understand for beginners. But saying that Klaus, when broken down and read very carefully, the demo app is actually quite straight forward to follow as you've kindly included comments wherever applicable which is excellent.

I personally think that if B4X developers already know what sort of chart they need, then that's half the battle won when using xChart.
