  • Unsure what the issue is but the second parameter to GetFiles in a search pattern e.g.

    ' Only get files that begin with the letter "c".
    Dim dirs As String() = Directory.GetFiles("c:\", "c*")

    There are three examples, all do the same. Since you are using VS2013 start from the last one as the first two may not work with VS2013.

    ' Get all text files beginning with aa1 and set the to
    ' the data source of a list box. In this case the path
    ' is the app folder but can be any folder you want.
    ListBox1.DataSource = Directory.GetFiles(
        AppDomain.CurrentDomain.BaseDirectory, "aa1*.txt").
        Select(Function(file) Path.GetFileNameWithoutExtension(file)).ToList()


    Dim results = Directory.GetFiles(
        AppDomain.CurrentDomain.BaseDirectory, "AA1*.txt").
            Select(Function(file) Path.GetFileNameWithoutExtension(file)).ToList()
    For Each item As String In results


    Dim results = Directory.GetFiles(
        AppDomain.CurrentDomain.BaseDirectory, "AA1*.txt").ToArray()
    For Each item As String In results

  • Its not clear what your question is. Try to make a smaller question. Just one line of code maybe that you don't understand. We cant know what you want to do. You need to show what you have and what you want.

    There are several lines of your example that are not correct. Maybe this will help for a working example of what you want?

    Public Class Form8
        Private Sub Form8_Load(sender As Object, e As EventArgs) Handles MyBase.Load
            ComboBox1.Items.Add("Item 1")
            ComboBox1.Items.Add("Item 2")
            ComboBox1.SelectedIndex = 0
        End Sub
        Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
            'use the sender to avoid late binding 
            Dim cbox As ComboBox = DirectCast(sender, ComboBox)
            Dim itemName As String = cbox.Items(cbox.SelectedIndex).ToString
            Select Case itemName
                Case "Item 1"
                    Label1.Text = "Item 1"
                Case "Item 2"
                    Label1.Text = "Item 2"
                Case "rusty"
                    Label1.Text = "rusty"
                    Dim Files() As String = IO.Directory.GetFiles("c:\bitmaps\", Label1.Text & "*.*")
                    For Each file As String In Files
                        Label1.Text &= vbLf & (IO.Path.GetFileNameWithoutExtension(file))
            End Select
        End Sub
    End Class
