programmatically changing mouse, keyboard, and display settings -- c#

Hello:

I'd like to set mouse and display settings programmatically without
having to log out or restart. Is this possible by making registry
settings and then having the winlogin process re-read the registry? Or
is there another way to do this? I will likely need to capture
multiple settings from a host computer and put them into effect on a
target machine.

Thanks.

Hello Mark,

I do know you can do it with the display settings by using the
ChangeDisplaySettingsEx Windows API. As far as I remember there is a flag
telling the system that the changes should be applied without a reboot.

Thanks Dmytro. I can do it using SystemParametersInfo which can do a
broadcast with SPIF_SENDCHANGE. Since my settings are captured in a
reg file, I'd rather import the settings via a call to regedit and have
the changes immediately take effect. SendMessageTimeout using a
broadcast does not work. It seems to be very difficult to get apps to
"see" changes made to the registry w/o restarting.

Thanks.
