hi. i'm a newbie here, and an amateur in programming. i was wondering if you could help me answer my problem with the program that i'm writing. i'm using 3 NumericUpDown controls to get an output and convert it to a Date. i don't know if i am doing this right, and i've been working on this overnight. i'll put the codes that i've written:

Private Sub btnDaysOld_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDaysOld.Click
        Dim shoMonth As Short
        Dim shoDay As Short
        Dim shoYear As Short
        Dim strBirthday As String
        Dim datBirthday As Date
        Dim lngDaysOld As Long

shoMonth = Convert.ToString(nudBirthMonth.Value)
        shoDay = Convert.ToString(nudBirthDay.Value)
        shoYear = Convert.ToString(nudBirthYear.Value)

[B]strBirthday = shoMonth.ToString & shoDay.ToString & shoYear.ToString[/B]

[B]datBirthday = Date.Parse(strBirthday).ToShortDateString[/B]        
        lngDaysOld = DateDiff(DateInterval.Day, datBirthday, Today)
        lblDaysOld.Text = lngDaysOld.ToString

End Sub

i'm trying to get the interval days between the two Dates (the Date today, and my birthday). the bolded texts are the ones that i want to know if i'm doing the right thing. because when i run the program, the error says "Format Exception was unhandled: String was not recognized as a valid DateTime".

how can i combine the output from those nud controls to convert it to a string, and then to a Date? i would greatly appreciate your help to solve my problem. Thanks..
