setcurrent page for pdf

[Navarone]

I am using a shell execute to open a pdf. How do I open the pdf to a certian page? I read that you can use the setcurrentpage property. How do you use this. In my module I have a public function and then on my form in my flexgrid I call the function.

Public Function OpenPDF(ByVal pdf As String) As Long
  OpenPDF = ShellExecute(0&, vbNullString, pdf, vbNullString, vbNullString, vbNormalFocus)
End Function
 
Private Sub MSFlexGrid1_Click()
OpenPDF (App.Path & "\" & "Howe Vol 2.pdf")
End Sub
