ShellExecute in VB2005

Does ShellExecute work in VB2005? I am trying to open a pdf with a button - I
get no errors, but nothing is happening. Here is my code:
Option Explicit On

Public Class frmPROTest
    Const SW_SHOWNORMAL = 1
    Dim hwnd

    Private Declare Function ShellExecute Lib "shell32.dll" Alias
"ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
ByVal lpParameters As String, ByVal lpDirectory As String, _
ByVal nShowCmd As Long) As Long

Private Sub PDF_Click()

        Call ShellExecute(Me.hwnd, "open", "S:\Users\JJolly\PRO
CD\pdf\english\ESY Book.pdf", "", 0, SW_SHOWNORMAL)

    End Sub

End Class

Thanks for any help.

Your declarations are wrong. Instead of fixing them, I suggest to use
'System.Diagnostics.Process.Start' instead of 'ShellExecute'.

I have also tried 'System.Diagnostics.Process.Start', but apparently my
declarations are wrong when I try it too because nothing happens at all. Can
you just give a short code snippet that would include everything I need to
open a pdf file using 'System.Diagnostics.Process.Start'?
Also, we want this program to be run directly from a CD with no installation
- how do I go about doing that?
Thanks.

Jedi10180,

Programs written in a .Net language require the .Net framework to be
installed in order to execute the program.

Have you considered the following method using the .NET framework?

\\\
    Dim proc As New Process

    With proc.StartInfo
        .FileName = "S:\Users\JJolly\PRO CD\pdf\english\ESY Book.pdf"
        .UseShellExecute = True
        .Verb = "open"
    End With

    'Launch the file
    proc.Start()
///

why doesn't cmd.exe with arguments /c copy c:\file.txt d:\directory work with
the process start?
