String functions

[straybullet]

Ok I maybe missed it in the docs...


But I want to see if a string begins with the number 1 and if so remove it from the beginning only. I don't care if the number 1 appears anywhere else in the string, it as long as its not at the beginning.


Some languages have strleft and strreplace, but do not see them in B4a, any suggestions will be greatly appreciated.

Thanks

You have to use "StartsWith", for example:

Dim str As String

If str.StartsWith("1") Then ...

Not asking to you to code it for me, but if there a trimleft command I am missing?


Thanks

There's no "TrimLeft" but you can do something like this:

Dim str As String

str = "1 Hello there"

If str.StartsWith("1") Then

   str = str.SubString(1)
         
End If

Msgbox(str, "")

Thanks you two, Margret I noticed the following..

s.At()
s.Left()
s.Len()
s.Ltrim()
s.Mid()
s.Right()
s.Rtrim()
s.Stuff()
s.Trim()
s.Val()

Am I missing a library or these built in commands I have not found docs on?

Those functions are a code module written by Margret and some other members, they are no part of B4A.

Hello, it is a code module. No libraries are needed. You can download it from the link I gave. You can unzip it and then copy and paste the code in a module named s.

Thanks NJDude. I was typing and got a phone call. When I posted I saw you had already posted the answer.


Thanks

What about...
if string.indexOf("1") = 1 then

Encrypt and Decrypt

Hi,
Any idea how to use the Encrypt and Decrypt function in StringFunctions library?

How can I specify the salt/key for it?
