Unable to convert a string to an integer variable from DateTaken attribute on a JPG file

Question

I have a script which is using the EXIF data from a JPG file to find the DateTaken value. Once found, place the data in $Year and $Month

Answer 1

The date-and-time string returned by $objFolder.GetDetailsOf($File, 12) contains invisible control characters^[1], for reasons unknown to me.

You can strip them as follows, after which your code should work:

# Remove the formatting control characters from the string, by replacing
# all instances of Unicode character category \p{Cf} with the empty string.
# For more info on Unicode categories, see http://www.regular-expressions.info/unicode.html
$dateTimeStr = $objFolder.GetDetailsOf($File, 12) -replace '\p{Cf}'

[int] $yeartaken = $dateTimeStr.Split("/")[2].Split(" ")[0]
[int] $month = $dateTimeStr.Split("/")[1]
$monthname = (Get-Culture).DateTimeFormat.GetMonthName($month)

As an aside, on a general note: Ansgar Wiecher's answer shows more robust date-time string parsing techniques.
