Un dev Microsoft a une araignée au plafond

Je fouillais sur des site de programmation pour trouver une info et j’ai trouvé ça. C’est une petite référence, qui la trouvera ? Un indice dans le titre.

Public Shared Sub Main()
        Application.Run(New Form1())
    End Sub 

    ' Populates the DataGridView. 
    ' Replace this with your own code to populate the DataGridView. 
    Public Sub PopulateDataGridView()

        ' Add columns to the DataGridView.
        dataGridView1.ColumnCount = 2
        dataGridView1.Columns(0).HeaderText = "Last Name"
        dataGridView1.Columns(1).HeaderText = "City" 
        ' Put the new columns into programmatic sort mode
        dataGridView1.Columns(0).SortMode = _
            DataGridViewColumnSortMode.Programmatic
        dataGridView1.Columns(1).SortMode = _
            DataGridViewColumnSortMode.Programmatic

        ' Populate the DataGridView.
        dataGridView1.Rows.Add(New String() {"Parker", "Seattle"})
        dataGridView1.Rows.Add(New String() {"Watson", "Seattle"})
        dataGridView1.Rows.Add(New String() {"Osborn", "New York"})
        dataGridView1.Rows.Add(New String() {"Jameson", "New York"})
        dataGridView1.Rows.Add(New String() {"Brock", "New Jersey"})
    End Sub 

    Private Sub SortButton_Click(ByVal sender As Object, _
        ByVal e As EventArgs) Handles sortButton.Click

        ' Check which column is selected, otherwise set NewColumn to Nothing. 
        Dim newColumn As DataGridViewColumn
        If dataGridView1.Columns.GetColumnCount(DataGridViewElementStates _
            .Selected) = 1 Then
            newColumn = dataGridView1.SelectedColumns(0)
        Else
            newColumn = Nothing 
        End If 

        Dim oldColumn As DataGridViewColumn = dataGridView1.SortedColumn
