unable to change date format

[clausowitz]

I am trying to convert a date into another format.

           FixDate = "17 JULI 2018"
            Dim newDate As Date = DateTime.ParseExact(FixDate, "YYYYMMDD", Globalization.CultureInfo.InvariantCulture)
            finalstring = newDate.ToString

I get an error saying the date format is not recognized.

The result should be a date in string like this: 20180717
