| Folks, a long shot I know, but I thought I'd ask.
Is there any way that anyone knows of forcing a driver reset on Windows CE?
I'm specifically after causing the MQ200 driver to reinitialise and re-read the registry settings without having to warm reboot the machine... If I can get this working, then I'll have a fairly decent control panel applet for the G138.
I'll ask on the microsoft.public.windowsce developer groups too... |

| you can have the display driver reread the registry settings, if thats what you need, szilamer knows the details  |

Can you pass this thread onto szilamer and get their input? |

| cmonex and chiark
The method cmonex metioned only works for backlight.
HANDLE hEvent = CreateEvent(NULL, TRUE, TRUE, L"BackLightChangeEvent" );
SetEvent(hEvent);
This one rereads the registry settings only for backlight.
But maybe you should run itsme util's testpi ( from xda-developers ) on Smartbook, and maybe you'll find your event. I don't know.

| Cheers for that, I'll give it a go - I don't know of anything that forces a re-read of the registry short of a reinit of the driver. Perhaps there is a way... No, scrap that, there *must* be a way |

| Is this going to allow setting external resolution and so on? If so, great, i've been trying to create something but with little sucess.
I dont think its possible to 'refresh' a driver, based on the fact that Nyditot still requires you to soft reset.
EDIT: Is this applet in EVC and will you be making the source code available?
EDIT2: Any chance of screenshots of the work in progress? Edited by chazco 2006-09-11 2:16 PM

| Chaz, another applet manages to do it for the MQ200... The airspeak or wyse 3820tx seem to allow it. And yes, not at the moment, no, to the other questions |

nyditot 4.x and newer will not require a reset.. only for the first time, after that it will be able to do all changes on the fly on ce.net! |

| Looks like I've found a likely api call - ChangeDisplaySettingsEx...
I'll have a play, but I don't have the 138 to hand at the moment - bah! |

| Good to hear, hope it works |
