I have been reading over the B4X Guides and found a few typos.
E.G. B4X Graphics
2.3.1.1 XUI
B4X:
Sub Process_Globals
Private xui As XUI
Private xplGraph As B4XView
Private cvsGraph As B4XCanvas '--- I asuume this should be xcvsGraph ?
End Sub
xplGraph = xui.CreatePanel("")
xcvsGraph.Initialize(xplGraph) ' or this should be cvsGraph ?
2.4.1 XUI Drawing methods
On the 7th line ...
x, y. x1, y1, x2, y2 As Float are coordinates, Float variables.
x, y, x1, y1, x2, y2 As Float are coordinates, Float variables. <<< y,x1 not y.X1 ?

But I am new to this so I could be wrong !

Overall, I find the B4X Guides a fantastic resource especially during/after watching the ETP videos.
I would be lost without both!

Two weeks ago, I didn't even know what I didn't know. Now at least I know what I don't know. :cool:
So I can reference the Guides/Videos and try to figure it out !
The more times I read/watch them the better my understanding as to how everything works together.

Great Work BTW !!! If I notice anything else I will post here.

I know what I don't know.
Which reminded me of ancient philosopher Socrates.. (yes, there's ample debate on whether a similar phrase should be attributed to him or even ever told, but let's keep with the simplistic tradition).

I am going to retract and amend my original statement ...
From:
Now at least I know what I don't know.
To:
At least now, I am beginning to get an inkling of the depth of knowledge that still eludes me in my quest for B4X competency.
But, I shall endeavor to persevere and hence forth, I shall always; Check the B4X Guides, Review the ETP Videos, and Search the Forums. I shall pursue this course of action so that I may acquire the aforementioned knowledge. Also, so that the venture I have embarked upon will ultimately be successful and my journey with B4X richly rewarded, spiritually and intellectually, if not monetarily.

I wish you all extraordinary health and prosperity on your quests !

Be aware that the dimensions of Page1 are not known in Application_Start, the are only known in
the Page1_Resize routine in the Width and Height parameters.

Suggestions (they/the dimensions ?)

I am a "wanna be" B4X "Expert" :cool:

Centuries ago (LOL!) I was a "Support Programmer". I looked at a lot of "dumps" and error logs in my past life.

I have always been very detail oriented and my brain works in mysterious ways. I can tell you what caused an error code in a program from 20 years ago, but I can't tell you what I had for lunch yesterday !

Also, I am in the minority here. I can only speak/read/write in ONE language, English. I am not multi-lingual like everyone else on this site !!!

P.S.
When one of my coworkers apologizes for their "poor" English. I always try to reassure them and say,
"Don't worry about it, Believe me your English is a 1000% better than my (insert language here)!" :)

Now if I could code B4X Programs as well as I can proof read that WOULD be an accomplishment in my book !!! LOL !!!

Fortunately for me, I have the resources to reference that a lot of forum members (and Erel of course) put a lot of time and effort into to make my B4X journey easier !!!

Too bad it was just what I would have asked you. What did you eat yesterday?
