Loading file on axacropdf (pdf component) from mixed listbox

Question

I'm getting the folder names, and getting the pdf files at the same directory, and listing both in the same listbox with this code:

        Private Sub frmBooks_Load(sender As Object, e As EventArgs) Handles MyBase.Load
For Each folder As String In System.IO.Directory.GetDirectories(Application.StartupPath & "\Books")
        ListBox1.Items.Add(Path.GetFileName(folder))
    Next
    For Each file As String In System.IO.Directory.GetFiles(Application.StartupPath & "\Books\", "*.pdf")
        ListBox1.Items.Add(Path.GetFileNameWithoutExtension(file))
    Next

BOTH are MIXED and SORTED in the same listbox1 Then i add axacropdf (PDF component) to read pdf files. How can i open/get the path from selected item at listbox to open at axacropdf??

(axacropdf.src =)

Answer 1

This code check if the file exist as .pdf

Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
    If File.Exists(Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf") = True Then
        AxAcroPDF1.src = (Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf")
end if
   end sub
