Please help.

I am trying to write a program to determine if a year is a leap year or not. It is driving me nuts, i know nothing about leap years. Here is the question.

"The current calendar, called the gregorian calendar, was introduced in 1582. Every year divisible by four was declared to be a leap year, with the exception of the years ending in 00(that is, those divisible by 100) and not divisible by 400."

i cant figure out how to even go about it, here is as far as i got with my coding.

Code:

---

Public Class Form1

    Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
        Dim year, value, value2 As Double
        year = CDbl(txtYear.Text)
        value = year / 100
        value2 = value / 4

        MessageBox.Show(CStr(value2))
       

    End Sub
End Class

---

try this:

vb Code:

MsgBox(Date.IsLeapYear(1582))

thanx alot dude, i never would have thought of that

If this is homework, your teacher may not accept Paul's solution since the purpose of the exercise is to help you learn how to turn an algorithm into code.

you can calculate leap years easily, using the specifications you provided in post #1:

vb Code:

Dim Y As Integer = CInt(txtYear.Text)
 
If Y Mod 4 = 0 And Not Y Mod 100 = 0 Or Y Mod 4 = 0 And Y Mod 400 = 0 Then
   'is a leap year
End If
