Developers

My name is Bradley and I have been developing for 2 years now using visual basic 2008 express edition I am also a developer and use assembly programming language.

Problem

I have a listbox that displays all files in a spersific directory and already have the code for showing the files and there extentions the probelm I am faceing is when I go to open a file some are URL and some are .doc and it don't know which one to open I need a peace of code that will allow to be open the file and it automaticly detects its exttention so any file for .doc = moduel 1.main and for URL goes to moduel 2.main here is the code so far

Moduel 1

Module Module1

Code:

Sub Main()
        OpenMicrosoftWord("C:\Travel\" & Form1.ListBox1.SelectedItem.ToString)
    End Sub
    Private Sub OpenMicrosoftWord(ByVal f As String)
        Dim startInfo As New ProcessStartInfo
        startInfo.FileName = "WINWORD.EXE"
        startInfo.Arguments = f
        Process.Start(startInfo)
    End Sub
End Module

Moduel 2

Module Module2

Code:

Sub Main()
        Process.Start("C:\Travel\" & Form1.ListBox1.SelectedItem.ToString)
    End Sub

End Module

Load form1

Code:

For Each FileStr As String In IO.Directory.GetFiles("C:\Travel", "*.*")
            ListBox1.Items.Add(IO.Path.GetFileName(FileStr))
        Next

open Button1

Code:

If ListBox1.SelectedItem = "*.doc" Then
            Module1.Main()
        End If
        If ListBox1.SelectedItem = "*.URL" Then
            Module2.Main()
        End If
