Launch a pdf file from vb program

What is the eaisest way to launch a .pdf file from a VB program?

using ShellExecute I think

VB Code:

Option Explicit
 
 
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
                (ByVal hwnd As Long, ByVal lpszOp As String, _
                 ByVal lpszFile As String, ByVal lpszParams As String, _
                 ByVal LpszDir As String, ByVal FsShowCmd As Long) _
                 As Long
 
 
Private Sub Command2_Click()
    'Open a document
    Dim l As Long
    l = ShellExecute(Me.hwnd, "Open", App.Path & "\Test.pdf", "", "C:\", vbNormalFocus)
End Sub
