Is there a way to change the format the calendar control uses on the form? (currently it is mm/dd/yyyy)
DateFormat("dd/mm/yyyy") only changes the format given in the "Today:..." part when you open the control. When you select a date the result shown in the control is once again in the mm/dd/yyyy format.
Sub App_Start
DateFormat("dd/mm/yyyy") 'this one doesn't make a difference
Form1.Show
End Sub
Sub Button1_Click
FirstTime=Date1.Value+TimeParse(Hour1.Text&":"&Min1.Text)
SecondTime=Date2.Value+TimeParse(Hour2.Text&":"&Min2.Text)
ResultTime=SecondTime-FirstTime
End sub
