Calculate the age

This sample code shows how to calculate the age of a person.


Public Function DateLimit(ByVal dtp As DateTimePicker)
Dim i As Integer
i = DateDiff(DateInterval.Year, dtp.Value, Date.Today)
If i < 18 Then MessageBox.Show("Age should be above 18", "SMAS", MessageBoxButtons.OK)
End If
End Function

Public Sub CalcAge(vDate1 As Date, vdate2 As Date, ByRef vYears As Integer,
ByRef vMonths As Integer, ByRef vDays As Integer)
' Comments : calculates the age in Years, Months and Days
' Parameters:
' vDate1 - D.O.B.
' vDate2 - Date to calculate age based on
' vYears - will hold the Years difference
' vMonths - will hold the Months difference
' vDays - will hold the Days difference
vMonths = DateDiff("m", vDate1, vdate2)
vDays = DateDiff("d", DateAdd("m", vMonths, vDate1), vdate2)
If vDays < 0 Then
' wierd way that DateDiff works, fix it here
vMonths = vMonths - 1
vDays = DateDiff("d", DateAdd("m", vMonths, vDate1), vdate2)
End If
vYears = vMonths \ 12 ' integer division
vMonths = vMonths Mod 12 ' only want leftover less than one year
End Sub

Its working for me
