I have a problem with set lenguage to MDI forms. In my main form I have a menustrip and I use resource file for translate

I wanted to know if I'm doing the right thing

My code is this (Example):

Public Class Main

   Public SNFrm As New SalesNote

   Private Sub SetLanguage()

      SNFrm.Text = My.Resources....
      SNFrm.AcceptBtn.Text = My.Resources...

   End Sub

   Private Sub MenuSalesNote_Click(......)

    SNFrm = New SalesNote
    SNFrm.MdiParent = Me
    SNFrm.StartPosition = FormStartPosition.CenterScreen
    SNFrm.Show()

   End Sub

End Class

Then, in My SalesNote Form_Closing Event

Main.SNFrm.Dispose()

is this correctly? Help!
