I have an application that saves its window size and position into a
file upon close and reopens in the same position next time.

Unfortunately it doesn´t work on a dual screen system, no matter on
which screen the window is located before close, it always (re-)opens
on the 1st screen.
It does keep its position on the screen, it just doesn´t remember on
which screen it has been.

In other words, I need a way to include the screen identification into
the save of window position and upon reopen I have to MoveWindow()
onto the right screen.

Is there a way in GetWindowRect() or GetClientRect() and MoveWindow()
to do this, or how else can it be done?

I suspect you need MonitorFromRect to determine which monitor the
window is displayed upon. Take a look at this link and see if it
helps.

None of those APIs care about the screen, they treat multiple monitors
as one large desktop. Perhaps with the exception of creating a
maximized window on the proper screen, you shouldn't have to worry
about it either. Can you show the code that's failing?

Thank you, that´s exactly what I needed.
I just didn´t know these functions exist, but now that I know, I
should be able to figure out the code myself.
