Inactive top window?

[David Olsson]

Hello!

I'm trying to place a window on top of all other windows without making
it active. I have made attempt with the SetWindowPos API call:

SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE |
SWP_NOMOVE | SWP_NOSIZE);

This, however, appears to have no effect. If I remove the SWP_NOACTIVATE
flag, the window is moved to the top. It does however (obviously) get
activated which is something I, in this case, do not want. Am I missing
something? Or there is another API call which provides the functionality
I am looking for?

you forgot the SWP_SHOWWINDOW flag:

SetWindowPos (hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE |
SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW);

Thanks for the reply. I should have written that I tried with that flag
as well, without success. As far as I can gather, this is the API call
used to implement "always on top" behaviour. And since windows that are
"always on top" aren't always active, I'm guessing there is a way to do
this :-).

Thanks for any other suggestions

If the topmost really implies show then there is as i see it two solutions:
1. SW_HIDE , topmost, SW_SHOWNOACTIVATE
2. hwnd=GetForgroundWindow(), topmost, SetForgroundWindow(hwnd)

It all kinda depends on where you are doing this. Anyway if the window that
you are trying to change the Zorder of is not already active call
SetWindowPos with the SWP_NOACTIVATE flag.

I would guess that the window you are trying to make topmost is not active
when you are trying to make it topmost. I ran into this problem when
writing an app bar at tries to respond correctly to full screen app
notifications. I spent a lot of time debugging this and concluded it is a
defect in Windows, but they haven't gotten back to me yet.

IIRC, I worked around this in the end by not having any owned windows at the
time I need to make the window topmost. For me this meant making my
tooltips topmost and not owned by the parent window. Not a great solution,
but works reasonably well.
