^^ you cannot directly pass the enum season or month cause its a type. you have to declare a variable and then passthat to the function
something like this, just a rough example.
Code:
Public Enum season
winter = 0
summer = 1
End Enum
Public Enum month
jan = 0
feb = 1
End Enum
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim se As season
Dim mon As month
test(se)
test(mon)
End Sub
Sub test(ByRef ses As season)
MessageBox.Show(ses.summer.ToString & vbCrLf & ses.winter.ToString)
End Sub
Sub test(ByRef mo As month)
MessageBox.Show(mo.feb.ToString & vbCrLf & mo.jan.ToString)
End Sub
