VS 2008 Pick file with mouseclick on desktop and display name in textbox or MsgBox - HELP!

I want to do the same as this but instead of drag and drop, I want to do it with left mouse_click

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Me.AllowDrop = True
End Sub

Private Sub Form1_DragDrop(sender As System.Object, e As System.Windows.Forms.DragEventArgs) Handles Me.DragDrop
Dim files() As String = e.Data.GetData(DataFormats.FileDrop)
For Each path In files
MsgBox(path)
Next
End Sub

Private Sub Form1_DragEnter(sender As System.Object, e As System.Windows.Forms.DragEventArgs) Handles Me.DragEnter
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
e.Effect = DragDropEffects.Copy
End If
End Sub
