PS: Could you please change the name of the B4X Basic Language booklet into B4X Language in the Documentation pages.

Done.

I'm uploading the correct Booklets zip. Should be online in a few minutes.

New method ?

It is a bit cumbersome but you can link to a specific page with an anchor: https://www.b4x.com/guides/B4XLanguage.html#pf2
The tricky part is that it expects a hex value.

Hi @klaus,
Please update the Last update date. Thanks.

 

[klaus]

The dates will be updated for the next edition.
The edition number is the most important not the date.

 

[aeric]

The B4X Booklets have been updated to version 2.4.
Changed all links to show the inline booklets.

I assume the only changes are the links. The contents are remain the same as version 2.3.

 

[klaus]

Yes.
I have removed just two or three typos (already old ones).

Amazing work Klaus, thank you!!!

I started studying the documentation. First, I quickly looked through all the .PDF files. The impression is amazing! Everything is described in clear language and demonstrated in detail with numerous illustrations. I can imagine how much work you Klaus put into this.

Now I started studying B4XGettingStartedV2_5.pdf in detail and, unfortunately, on page 17, I discovered an annoying inaccuracy. Of course, this does not affect the general understanding of the material, since, logically, one can understand that we are talking about .b4j files, and not about . b4a, but still I considered it necessary to report this for future editions of this .PDF file.

At first I wanted to send a private message, but I couldn’t find a way to do this, so I had to write here. I suspect that forum newcomers are blocked from sending private messages until a certain number of posts have been published. And perhaps that’s right.

Thank you for reporting this.
It is amended for the next edition.

Might be it's worth changing "Change the Package name to b4a.SecondProgram" to "Change the Package name to b4i.SecondProgram"?

Might be it's worth changing "In the B4i designer, right click somewhere in the dark grey rectangle." to "In the B4j designer, right click somewhere in the dark grey rectangle."?

P.S. Klaus, please tell me whether it makes sense for me to continue to publish in this thread all these minor inaccuracies that have been noticed?
In fact, when a person sits at a computer and presses buttons, following your detailed instructions, he or she may simply not pay attention to all these little things. Everything will be clear to him/her from the very logic of actions. But I’m not acting now, I’m just studying the documentation, waking up early in the morning from insomnia and reading it all on my tablet. That's why I notice it.

I would be glad, but, as I wrote earlier, for me it looks like forum newcomers are not allowed to send private messages to other members until they reach a certain number of posts.

When I press my envelope button, I get this almost empty small window. And even if I click on “Show all”, nothing worthwhile still appears.
And in your profile, I also don’t find a way to send you a private message.

Hi @oleg_
the "block" is not related to a minimum number of post sent so far, but to your status of new member.
Just do a small donation to Anywhere Software to become "Licensed User" or "Registered Member" (I can't recall the exact label).

Hi @oleg_
the "block" is not related to a minimum number of post sent so far, but to your status of new member.

Hi @udg
In fact, I personally don’t really need PM. On the contrary, in all forums and chats I prefer to write in general threads, because personal correspondence is something like conspiratorial whispering behind everyone else’s back, which I, in itself, don’t really like.
Well, I’m just not quite familiar with the local rules yet. I don’t know if it’s even useful to write in this thread my corrections to the inaccuracies noticed. Maybe this is tantamount to cluttering the thread or something like that?
Well, I just want to do a good deed for the site while studying the material and nothing more.

I am still at the selection stage and am not yet sure whether I even need this language.

 

[udg]

Sure. My post was meant just as an explanation about the apparently missing feature and for the delay you experience when posting. Nothing more.
