[Visual basic] Open file dialog in preklic

Torej po tem vodiču se učim programiranje in sem naletel na en problem. Namreč vse OK glede prikazovanja dialoga in to problem je kaj se zgodi, ko pritisnem na cancel v dialogu.V vodiču (link zgoraj) je napisano kaj bi moral naredit vendar to nekako ne deluje. Visual basic mi v primeru, da naredim to javi tale warning:

Warning Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated. C:\Users\Roli\Documents\Visual Studio 2005\Projects\menus\menus\Form1.vb

Napaka se nanaša na: DialogResult.Cancel


Še koda vsega skupaj:

    Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click

        Dim filename As String
        Dim DidWork As Integer = OpenFD.ShowDialog()

        OpenFD.InitialDirectory = "C:\"
        OpenFD.Title = "Open file"
        OpenFD.Filter = "Text Files (*.txt)|*.txt"
        filename = OpenFD.FileName

        If DidWork = DialogResult.Cancel Then
            MsgBox("Cancel Button Clicked")
        Else
            filename = OpenFD.FileName
            MsgBox(filename)
        End If

        MessageBox.Show(filename)

    End Sub

Pa še bi bilo dobro, da propertije nastaviš preden kličeš ShowDialog()
