Issue with sending event.

Hi,

I am having a problem at the moment.

I am updating the GDI\Rotation value in the registry on the device, but
this is not actually rotating the screen. When i check the registry, it
has been updated and if i perform a soft-reset, then the display gets
correctly rotated. does anyone know which event i need to send, to
force windows to re-read the values from the registry and therefore
update ? I've been looking at this for hours and got no where.

Many thanks in advance

You're certain your hardware supports rotation?

Steve,
Any modification to the registry almost always involves a soft reset, so
what you did was right. If you were to go back and modify it again, you
would once again have to perform a soft reset. Because your unit didn't come
with an easy app in settings to rotate your screen, changing the settings in
the registry becomes almost permanent unless you go back and change them
again.

Hope this helps.

Thanks guys,

But what i really need to know, is, is there a call i can make, to
force windows (ppc) to reload the settings from the loacal
machine\system\gdi section of the registry and update the system
(turning the screen to the required rotation).

I have already tried a number of methods, but with no joy. I was
wondering if there is a method of sending a named event, such as you
can with the backlightchangeevent

Hoping someone can help

Thanks

Steve

If rotation is supported, it probably works with ChangeDisplaySettings as
well. That's the correct way to dynamically change the setting.
