ShellExecute to open a hidden window not working

[talln6e]

I want to exec a url in VB6 or Vb.Net, but NOT open a
window when doing so.
Using ShellExecute from VB6 with 0 for a hidden window is
the closest I can get, but the window is opening anyway.
Does anyone know another way?
This is my current code:

Dim myurl as string
Dim res As Long

myurl = "

http://www.mydomain.com/myapp.asp"

'res = ShellExecute(0&, "open", myurl, vbNullString, vbNullString, vbNormalFocus)
res = ShellExecute(0&, "open", myurl, vbNullString, vbNullString, 0) '0 is for hidden window

Thanks for any help anyone can give.
