Why isn't this class working?

[MdWebtress]

I'm using ASP.NET (VB), and I'm trying to use a class to display a custom popup function (alert().

Public Class msgClass
    Inherits System.Web.UI.Page
    Public Shared Sub alert(ByVal msg As String)
        Response.Write("<script>alert('" + msg.tostring + "');</script>")
    End Sub
End Class

The problem here is that is says I need an explicit instance of a class to use response. (Not sure how to do that...)

This is how I call it in my main ASPX.vb page:

                Dim a As New msgClass
                a.alert(IsDate(txtStartDate.Text).ToString)

I've tried using Public Sub, but when it gets there, it tells me that "response..." can't be used like that.

you using a namespace?

Ok, I've gotten it like this:

Namespace Properties
    Public Class a
        Inherits System.Web.UI.Page
        Private a As Integer
        Private str As String
        Public Property setInt() As Integer
            Get
                Return a
            End Get
            Set(ByVal Value As Integer)
                a = Value
            End Set
        End Property
        Public Property setStr() As String
            Get
                Return str
            End Get
            Set(ByVal Value As String)
                str = Value
            End Set
        End Property
        Public Sub Message(ByVal str As String)
            Response.Write("<script>alert('" + a.ToString + "');</script>")
        End Sub
    End Class
End Namespace

I can call the Message() sub, but I get the error that: "Response is not available in this context. ". If I put in "Shared sub" I can't use it. ("Can't refer to an instance member of a class from within a shared method....")

What I mean rather, are you importing that namespace on the head of your asp.net page?
