All the code projects supplied with the Beginner's Guide and the User's Guide are example codes to illustrate different subjects.
All Basic4Android users can use them and modify them to their needs.
I don't think it would be really useful to put these onto GIT HUB nor Code.google which are hudge containers.
I'm sure that it is easier to search for a specific code in this forum rather than in much more generaland big forums.
That's the reason why the Code Snippets subforum was created.

You are right I was just trying to populate the B4A. Any thanks

I don't know if this was mentioned before (tried to do a forum search), but on the top of page 43 of the PDF it states "Click on pnlKeyboard", I think it should read "Click on btnAction" and then change that Parent to pnlKeyboard. I'm new, but that was the only way I could get the same results...

Page 49 - Image shows 5 occurrence(s) replaced ... When I did the example: 3 occurrence(s) replaced
Page 52 - Changed all the names from btnSender to Send without mentioning...​

5.4.1.5 Scaling strategy
[...]
This is done with SetTopAndButton and SetLeftAndRight methods.

I think it should be SetTopAndBottom, as written some line after

What is the difference between the User's Guide and the Beginner's Guide? If I want a thorough printed documentation set, which one(s) should I print?

The Beginner's Guide contains more basic documentation and the User's Guide more advanced documentation.
Beginner's Guide > tome 1
User's Guide > tome 2
Look at the tables of content to see the differences.

Thanks very much with the Beginner's Guide, I used it to write my first successful program.

Is there any plan updating a new version to address the change on B4A V.5.02(1)? Thanks.
