Actually there are 61 days between those two dates.
Dim date1 As Date = #10/10/2006#
Dim date2 As Date = #12/10/2006#
Dim ts As TimeSpan = date2.Subtract(date1)
Label1.Text = ts.TotalDays.ToString
This is mm/dd/yy. If dd/mm/yy then date difference is 2 days.
Don't know about the calender control.
Depends on what was meant by "how many days between two dates"
in dd/mm/yy format, there is technically "1" day between those two dates. Monday Oct 16 2006 to Wednesday Oct 18 2006, the day of Tuesday Oct 15 2006 would be the "1" day "between" those two dates.
Just all depends on what the original meaning was :)
Not sure of the actual code, but would be something like
Label1.Text = ts.TotalDays.ToString (-2) <hehe, like i said, thats probably not it but the concept is there>
The (-2) part (yes i know, not correct probably) would take away 2 from the resulting answer to account for the beginning date and ending date. Again, this is only if you wanted to find out the actual number of days BETWEEN two dates (not counting those days)
