Problem with Me: "Me it's only valid in a instance method"
Hi, I'm trying to make a winform (vb, VS2008) application that permits take a file from your hard drive and process it. I've tried to create a empty project with the structure but it appears empty. Until now I've this:
Inicio.Designer.vb:
Code:
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Inicio
Inherits System.Windows.Forms.Form
'Form reemplaza a Dispose para limpiar la lista de componentes.
<System.Diagnostics.DebuggerNonUserCode()> _
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
Try
If disposing AndAlso components IsNot Nothing Then
components.Dispose()
End If
Finally
MyBase.Dispose(disposing)
End Try
End Sub
'Requerido por el Diseñador de Windows Forms

Catch ex As Exception
Core.Log4Net.SaveError(ex)
End Try
End Sub

Doing this I'm obtainning 2 identical errors: "The instruction it's not valid in a namespace"
Looking info I've found that I should add something like this:
Code:
Imports System.Collections.Generic
Imports System.Linq
Imports System.Windows.Forms
Namespace WindowsFormsApplication1
NotInheritable Class Program
Private Sub New()
End Sub
''' <summary>
''' Punto de entrada principal para la aplicación.
''' </summary>
<STAThread> _
Private Shared Sub Main()
Application.EnableVisualStyles()
Application.SetCompatibleTextRenderingDefault(False)
Application.Run(New Form1())
End Sub
End Class
End Namespace
but here appears my problems again.
Code:
Namespace WindowsFormsApplication1
NotInheritable Class Program
Private Sub New()
End Sub
''' <summary>
''' Punto de entrada principal para la aplicación.
''' </summary>
<STAThread()> _
Private Shared Sub Main()
Application.EnableVisualStyles()
Application.SetCompatibleTextRenderingDefault(False)
Application.Run(New Inicio())
Rellenar_cb_Modelo()
End Sub
Public Shared Sub Rellenar_cb_Modelo()
End Sub
End Class
End Namespace
If I make this I'm obtainning the message: "Me it's only valid in a instance method". And if I take out the Shared I obtain 2 different errors:
1. Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
2. cb_Modelo it's not a "FicheroFacturacion.WindowsFormsApplication1.Program" member.
Any idea how to solve this? and more important, why? if it's not possible any idea will be appreciated. Thanks in advance.
Re: Problem with Me: "Me it's only valid in a instance method"
Solved, the solutions was this:
Code:
Imports Facturacion
Imports System.Windows.Forms
Imports System.Drawing
Imports System.Data
Imports System.Data.SqlClient
Imports System.IO
Imports System.Net
Imports System.Configuration
Imports System.Collections.Generic
Public Class Inicio
Public Sub Main()
Rellenar_cb_Modelo()
End Sub
Public Sub Rellenar_cb_Modelo()
The problem was that I was modifying the original file that was using a Module and loading the paths since the app.config and then I couldn't see the design view and the IDE couldn't show the errors.
