I get so many errors from this trying this in VS2012-VB. I simply want to find the difference between the selected dates in my two datepicker objects (DateIn & DateOut). If the difference is less than 7 I want a checkbox to be checked, greater than 7 days, unchecked. None of the solutions I have found on this site have helped at all.
Private Sub RushOrder()
    If DateOut.SelectedDate - DateIn.SelectedDate < TimeSpan.FromDays(7) Then
        chkRush = True
        chkRush = False
    End If
End Sub

Solution 1

Try :

Dim ts as TimeSpan = DateOut.Value - DateIn.Value
If (ts.TotalDays > 7)
   '' Do something when difference is greater than 7 days
   '' Do something when the difference is less than 7 days
End If

Hope this helps.

Actually, this doesn't help much. .Value is not a property or method of DatePicker object. At least on my machine. Am I missing a dependency or something?

I don't remember, and I don't have any IDE installed on this computer. Just find the property of your DateTimePicker object that holds the DateTime value ; auto-completion should help you here.
