Jump to Html help topic and tile the main app and help windows

I'm trying to implement context sensitive help in delphi 5, but since delphi
5 doesn't support the HTML  help, I had to resort to the API provided by the
HHCtrl.ocx control.  I got some code from the usenet which  wraps the API to
delphi functions and structures.  I can get the HTML help to appear, jumping
to the  particular help section in the file based on the context number by
utilizing the following code:

procedure GotToHelpContext(intContextID:integer);
var
  ret:THandle;
begin
  ret := hh(application.Handle,pchar('C:\MyHelp.chm'), HH_HELP_CONTEXT,
intContextID);
end;

There is a ton of code for the usenet that I can post if needed that shows the hh function above.

But my client wants the help window to appear in a certain position on the
screen.  I could use the  SetWindowPos API call to reposition the window,
but the window flashes because makes its appearance in the  default position
first before moving to the desired position.  I know I can set the
HH_WinType structure  with the my desired coordinates and window size, but I
need to know what goes in that structure.  I tried  getting the HH_WinType
structure using the HH_GET_WIN_TYPE message, but the structure doesn't get
filled.   Calling HH_SET_WIN_TYPE with the returned structure causes an
access violation.  What am I doing wrong?
