datetimepicker value is always true

[jmcilhinney]

The Value property is type DateTime, so of course it always has a value. It's up to you to test the value of the Checked property and then use or don't use the Value property. It's not going to magic it for you.

If myDateTimePicker.Checked Then
    'Use myDateTimePicker.Value here.
Else
    'Don't use myDateTimePicker.Value.
End If
