Hi,
I'm trying to compile a simple code Prova.aspx.vb, but I get this error:

[root at localhost Desktop]# mbas /t:library /out:Prova.dll Prova.aspx.vb

Prova.aspx.vb(2,7) error BC29999: Parsing error

---------------Prova.aspx.vb----------------------------------------
Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click

        Label1.Visible = True

        Label1.Text = "Hai cliccato il bottone"

    End Sub
End Class
-------------------------------------------------------------------
Why?

How I can compile this file?

thank's,

Valentina.
