Variables declarations: What's the difference? (RESOLVED)

[AlvaroF1]

What's the difference between it:

Public Class Form1
    Inherits System.Windows.Forms.Form
    Dim myVar As String = "Some text" 'Variable declaration here
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox(myVar)
    End Sub
End Class

And it:

Public Class Form1
    Inherits System.Windows.Forms.Form
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim myVar As String = "Some text" 'Variable declaration here
        MsgBox(myVar)
    End Sub
End Class

?

Thanks.
