[RESOLVED] Need help for a specific navigation to items in a List Box - VB 2010

[vbnewbieuser]

Hi!

I created a listbox that adds files with specific extensions. The files are of type: *.zip, *.rar, and *.7zip. I have many files in a directory of each of these extensions. Assuming the selected item in my listbox is of type *.7zip, I wanted it when I pressed key 1 on the keyboard, I navigated directly to the first item of type *.rar. And as soon as the first item of type * .rar was selected in my listbox, if I pressed the key 1 again, I navigated straight to the first item of type * .zip. Is it possible to create something like this?

My code to create the listbox is:

Public Class Form1

  Dim directory = Application.StartupPath & "\zipfiles"

    Dim zip1() As System.IO.FileInfo
    Dim zip2() As System.IO.FileInfo
    Dim zip3() As System.IO.FileInfo

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        zip1 = dirinfo.GetFiles("*.7zip", IO.SearchOption.AllDirectories)
        zip2 = dirinfo.GetFiles("*.rar", IO.SearchOption.AllDirectories)
        zip3 = dirinfo.GetFiles("*.zip", IO.SearchOption.AllDirectories)

For Each file1 In zip1
            ListBox1.Items.Add(file1)
        Next

        For Each file2 In zip2
            ListBox1.Items.Add(file2)
        Next

        For Each file3 In zip3
            ListBox1.Items.Add(file3)
        Next


End Sub

End Class

I thank you all for any help you can give.
