   ' create 2d array

    Dim data(,) As String

    Private Sub _2D_Array_Create_Search_Display_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        ' add data to the 2d array

        data = New String(,) {

                               {"3", "E", "F", "KL"}, {"4", "K", "L", "MN"},

                             }

        ' display 2d array data

        For i As Integer = 0 To data.GetLength(0) - 1 Step +1

            For j As Integer = 0 To data.GetLength(1) - 1 Step +1

                RichTextBox1.Text += data(i, j) + " - "

            Next j

            RichTextBox1.Text += vbNewLine

        Next i

    End Sub

' button search

    Private Sub ButtonSearch_Click(sender As Object, e As EventArgs) Handles ButtonSearch.Click

' clear the RichTextBox

        RichTextBox2.Text = ""

        ' search item position in 2D array data

        For i As Integer = 0 To data.GetLength(0) - 1 Step +1

            For j As Integer = 0 To data.GetLength(1) - 1 Step +1

                If TextBox1.Text.Equals(data(i, j)) Then

                    RichTextBox2.Text += "POSITION [ " + i.ToString() + " , " + j.ToString() + " ]"
