Hi all!

Is there anyone who could tell me how to get the handle of an invisible
window, e.g. a window created not on the default desktop
(winsta0/default, like a non interactive service). The FindWindow
function fails, but I know the window is created and I need to access
it. One way could be to force it to be created on the default desktop,
but I'd rather find another way.

Thanks

Silvia

If you know the class name, then pass it to the FindWindow API.

You can try to use OpenDesktop to retrieve a handle for the window's desktop
and then EnumDesktopWindow to retrieve all top levels windows of the
selected desktop.
If you don't know the desktop name, you can try to loop through all desktops
with EnumDesktops.

Your process should have rights to enumerate and access windows on the
hidden desktop.

I know the class name, but if the window is not created on the default
desktop (winst0/default)FindWindow fails, even though I specify the name.
Any hints?

Thanks

EnumWindowStations(), EnumDesktops(), FindWindow().

Don't forget to set your default winsta/desktop appropriately before
calling FindWindow. Also, unless you created that winsta/desktop
yourself, you may need to perform surgery on the ACLs of the winstas
and desktops returned.

Cheers,
Felix.
