B4J Question String contain NO NUMBERS characters

[petr4ppc]

Dear friends, please,

is here some simple soulution how to recognize not number characters in string?

For example if he string is "1254as5748"
Here si "as" inside the string....I can not use this string...

I need use only string with numbers....

Or the best solution is
1) get length of string
2) check each character if it is number = the character contain 1,2,3,4,5,6,7,8,9,0
3) delete or use this string

Thank you very much
Best regards

Hi,

use IsNumber, like

Dim s As String = "1254as5748"
Log(s & " is a number " & IsNumber(s)) ' False
Dim s As String = "12545748"
Log(s & " is a number " & IsNumber(s)) ' True
