Opening a PDF file in a specific page

I have a code to launch a file with its registered extension. So if I have a PDF, I can open it in Acrobat or a similar registered program for the extension PDF but what I need to do is to launch a PDF in a specific page via VB6. Has anyone done something like this

This is the command and what I would like it to do.

C:\Program Files\Adobe\Reader 10.0\Reader\AcroRd32.exe /A "page=149&pagemode=none" "D:\books\MCTS(70-562) ASP.Net 3.5 Development.pdf"

This is the function I am using:

Public Function StartDoc(DocName As String) As Long
Dim Scr_hDC As Long
Scr_hDC = GetDesktopWindow()
StartDoc = ShellExecute(Scr_hDC, "Open", DocName, "", "C:\", SW_SHOWNORMAL)
End Function
