Hi,

if I had a variable which consisted of a string like this $a = "abc-wertr01" sometimes the lenght of the sting can be longer. How can I extract the last two characters from the string?

I want to increase the number in the string by 1.. and to do that I need to turn that part of the string into an integer

Thanks

$TempName = "abc-wertr01"
$a = $TempName
$b = $a.Length
$c = $b - 2
$d = $a.substring($c)
$e = [INT] $d
$f = "{0:D2}" -f $e
$e++

worked it out
$TempName = "abc-wertr01"
$a = $TempName
$b = $a.substring($a.length -2, 2)

You need
$str.substring($str.length -2, 2)

where $str is your string.

LE: too slow :)

HTH,
