Turn off Top Most for form

I have a  form that pings my website every 30 minutes
Usually i am doing something else so the form is not visible
On a failure I call SetWindowPos to put the form on top of other programs. The problem is
the form cannot be hidden without unloading it once it is put on top.
How can i overcome this?
the code I am using:
Private Const SWP_NOMOVE = 2
Private Const SWP_NOSIZE = 1
Private Const Flags = SWP_NOMOVE Or SWP_NOSIZE
Private Const HWND_TOPMOST = -1
Private Const HWND_NOTOPMOST = -2
Private Declare Function SetWindowPos Lib "user32" (ByVal hWnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Public Sub SetWindowOnTop(ByVal p_hWnd As Long, Optional ByVal p_bOnTop As Boolean = True)
    If p_bOnTop Then
        Call SetWindowPos(p_hWnd, HWND_TOPMOST, 0, 0, 0, 0, Flags)
    Else
        Call SetWindowPos(p_hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, Flags)
    End If
End Sub

Calling it like this:
Call SetWindowOnTop(Me.hWnd, True)

Open in new window

Where is p_bOnTop set? I ask because it looks like if it were False then topmost would be turned off.

Have you tried calling it with the constant: HWND_BOTTOM?

does the HWND_NOTOPMOST turn off top_most ?
I am going to put the top most on a timer  with a sound
After so many seconds turn off top most

It does turn off top most, but it only sends the form to behind all the other topmost windows. It will still be in front of non-topmost windows.

I'm actually not sure (even from the attached's description) so maybe you should try Graham's suggestion.

MartinLiss i had this but, the form was stuck on top, had to unload the form
If Counter >= seconds Then
    Timer1.Enabled = False
    sndPlaySound ByVal 0, 0 'stop sound
   Call SetWindowOnTop(Me.hWnd, False)
    End If

maybe the HWND_NOTOPMOST will work. I read somewhere that the topmost will not work correctly from the ide

Try (as Graham suggested)

Call SetWindowPos(Me.hWnd, HWND_BOTTOM, 0, 0, 0, 0, Flags)

I wonder if widowstate = vbMinimized
would override topmost
I do not see a HWND_BOTTOM constant

You can substitute the number 1 or add this declaration.

Private Const HWND_BOTTOM = 1
