Private Sub Command1_Click()
Dim myYear As Boolean
If IsNumeric(Text1.Text) Then
If Text1.Text Mod 400 = 0 Then
myYear = True
ElseIf Text1.Text Mod 4 = 0 And Text1.Text Mod 100 <> 0 Then
myYear = True
Else
myYear = False
End If
If myYear = True Then
Picture1.Print Text1.Text & "是闰年!"
Else
Picture1.Print Text1.Text & "是平年!"
End If
Else
Picture1.Print Text1.Text & "不是数字"
End If
End Sub
方法二:
Public Function LeapYear(ByVal yea As Integer) As Boolean '闰年函数
If (yea Mod 4) = 0 Then
LeapYear = (yea Mod 100 > 0) Or (yea Mod 400 = 0)
End If
End Function
学习总结:
通用的步骤,可以使用函数,方便以后调用。
