Android Question dateutils problem

[tufanv]

Hello,

I have 2 strings that keep dates which are at this format : 2014-06-26

When I use dateutils.periodbetweendays(string1,string2) i get an invalid double error because of the "-" charachters. Is there any way to get the days difference with this format. ?

ty

Try this:

Dim date1 As String = "2014-06-23"
Dim date2 As String = "2014-06-26"
Dim oldDateFormat As String = DateTime.DateFormat
DateTime.DateFormat = "yyyy-MM-dd"
DateUtils.PeriodBetweenInDays(DateTime.DateParse(date1), DateTime.DateParse(date2))
DateTime.DateFormat = oldDateFormat

Dim oldDateFormat As String = DateTime.DateFormat
DateTime.DateFormat = "yyyy-MM-dd"

        DateTime.DateFormat ="dd/MM/yyyy - HH:mm:ss"
    forDate=DateTime.Date(DateTime.now)
    giorno=DateUtils.GetDayOfWeekName(DateTime.Now)   
    giorno=giorno.ToUpperCase

result of compile:

Parsing code. Error
Error parsing program.
Error description: Undeclared variable 'dateutils' is used before it was assigned any value.
Occurred on line: 213
giorno=DateUtils.GetDayOfWeekName(DateTime.Now)

This error is occurs after I've installed DateUtils version 1.05.
With version 1.03 no problem verified.
Thanks for help.
