Android Question Beginner - missing functions - installation issue?

[Kevin Moloney]

Hello. I recently made a new installation of B4A on a new computer. After creating a new program, I am struggling to get the most basic functions visible in intellisense (I use the left function in my example below, but most other basic functions are missing).

I start a new program and try to type in the left function, but it doesn't appear in intellisense:

After finishing typing the function anyway, I get the following error:

This feels like a missing library function, but I think I downloaded the necessary files and configured paths correctly, although I admit I was a bit confused by the download process. Here are my paths:

Any help would be appreciated.

your configuration dialog is missing the location of your additional libraries folder. fill that in.
hopefully you brought that folder with you from the old machine. if not, you'll have to bring each additional library in one by one as needed...

anyway, this is what you were probably looking for:

Dim sf As StringFunctions  
Dim f As String
f = sf.Left("kevin",3)

I added an new empty folder "C:\Additional Libraries" and set the (optional) path directory accordingly. It had no effect on the issue.

Thank you for your reply.

I guess I was assuming such basic functions such as "left" would be in the core library. Where would I locate the "stringFunctions" library?

Where would I locate the "stringFunctions" library?

I find the easiest way to locate a missing lib is to use the search feature (top right next to your account name/avatar.)

This might be of interest as well , regarding the suggested / proper method of storing additional librarys.

[B4X] Additional libraries folder

The additional libraries folder can be organized in a way that allows sharing cross platform libraries between B4A, B4J and B4i. From now on, the recommended way to organize the additional libraries folder: Additional libraries folder is set under Tools - Configure Paths. As you can...

I have my base folder also in the Documents folder which is backup'd / synced using Dropbox.

For anything you can do a search on the site. Surely (99%) you will find the answer to your question

StringFunctions2

StringFunctions2 In the forum one sees again and again that many beginners use the old StringFunctions Lib of margret. But you should not use this lib anymore. Therefore, I have made the effort to rewrite the Lib (B4A 8.50). This lib is for learning purposes only or for easier porting of VB...

Success! ?

I downloaded the stringfunctions2 library files and added them to my "additional directory" folder, then checked it in the libraries manager.

And this works great...

The only thing I worry about is what other additional libraries might I need to do basic functions? Some time ago (I'm talking several B4X versions ago) it seems that something as simple as a left function didn't require the declaration of an additional library object ... it seemed to be built into the core language. Was this an effort to streamline the core? Or has my recollection been tainted with age?

Thanks so much for your help!!!

Don't use StringFunctions library. You don't need it.

Everything is supported with the built-in string features.

Dim s As String = "Kevin".SubString2(0, 3)

 

[Kevin Moloney]

Erel, I cut and pasted your reply ...

Dim s As String = "Kevin".SubString2(0, 3)

It works, although the lack of the left, right, mid functions will take some getting used to. When were these functions deprecated (or am I misremembering their existence in B4A)?

Thanks

 

[Erel]

When were these functions deprecated

Never. You probably used the not-recommended StringFunctions library in the past.

Dim Kevin As String = "Kevin"
'Left
Dim s As String = Kevin.SubString2(0, 3)
Log(s)

'Right
Dim s As String = Kevin.SubString(Kevin.Length - 3)
Log(s)

'Mid
Dim s As String = Kevin.SubString2(1, 4)
Log(s)

Hi Erel ...
It looks like you previously somewhat addressed this issue for IOS here

Thanks!!
