Help not on top

Hello,
I am using HTML Help Workshop to make a help file for one of my apps. I am wandering is there any way to make it so that the help window is not always on top (above) my app's window? I've tried playing with styles a little, but can't get it to work. Not even "tool window" works.
Also from searching on the internet Ive read in a few places that it could be done using HtmlHelp(...) function and passing 0 for the first parameter (the window handle).
Basically something like this is what ive seen a couple of websites talk about:

Code:

---

Declare Function HtmlHelp Lib "HHCtrl.ocx" Alias "HtmlHelpA" (ByVal hwndCaller As Long, _
  ByVal pszFile As String, ByVal uCommand As Long, ByVal dwData As Long) As Long

---

and then somewhere else:

Code:

---

HtmlHelp(0&, "helpfile.chm", &H0, 0&)

---

but this doesnt do anything in my program.

Thanks for your help,

Latem
