REQ: Util to do a soft reset

[Guest caio1]

It would be handy to have a utility which just do a soft reset of the phone.

I know it's possible because sometime when I install some applications at the end of the process the phone asks me if I want to reset and choosing yes the phone shuts down and turn on again by itself.

We wrote one but I won't release it because I'm convinced that Soft Resetting the phone through code causes registry corruption because things don't get saved to the IPSM properly.

Strange than that microsoft implemented such a feature... however when it resets it shows the Smartphone2002 logo screen as when you use the power button to shut down.

Caio

[Guest Soyale]

Hmm. Not the way we do it so maybe that's why. What application are you thinking of that does this reset?

[Guest caio1]

Not an application... after installing a cab file it's the system itself which asks me wether to reboot or not.

It happens to me every time I upgrade PocketMVP.

Yup, rebooting the phone is an option you can add to a CAB file, if your installation requires it.

Caio1; there's not a lot of point creating one just to reboot the phone because it would take more button press to ran than just pressing the power button! :?

[Guest caio1]

Not if you add a speeddial. And however the power button is always so difficult to press.

Caio

[Guest Vector]

Speed dials aren't very "speedy" either :? , and what's wrong with the power button :?: :roll:

[Guest caio1]

I always have to rotate wether my phone or my hand to press it 8-D

and with a reset utility I don't have to wait for my phone has shut down to press again the power button to turn it on again.

Caio

[Guest Soyale]

So here's the solution then. Create a CAB file which contains this reset option but nothing else. Make it read only. Place it somewhere on the start menu and assign a speedial. Voila. Phone will reboot with only having to press and hold a single button.

[Guest caio1]

Great idea Soyale!

Who has the necessary to create cabs?

Caio

[Guest Soyale]

Richie. What's the setting in the CAB file? I can create the CAB to do this if I know what it is.

FWIW, here's a little applet that just calls the OS function directly. Unsigned, decert, blah blah blah...

Update: added an icon per request

quickreset.zip

[Guest Soyale]

Does it use KernelIOControl?

[Guest Palindrome]

Nice one, rcraswell. That applet of yours works fine.

[Guest rcraswell]

Soyale, nope. It uses ExitWindowsEx. The function is documented under Win32/PPC but not under Smartphone but still exists in aygshell.dll. No guarantees that it will still be there in future versions of the OS, but I imagine it's what the CAB file program uses to do its thing so it's a pretty safe bet that it's not going away any time soon.

#include <windows.h>




#define EWX_LOGOFF    0


#define EWX_SHUTDOWN  1


#define EWX_REBOOT    2


#define EWX_FORCE   	 4


#define EWX_POWEROFF  8




#define MAX_ERRSTRING	30




extern "C" WINUSERAPI BOOL WINAPI ExitWindowsEx( UINT uFlags,DWORD dwReserved);




int WINAPI 


WinMain (


	HINSTANCE	hInstance, 


	HINSTANCE	hPrevInstance, 


	LPWSTR  lpCmdLine, 


	int 	 nShowCmd


	)


{


	DWORD	dwerr	= 0;




	if (!ExitWindowsEx(EWX_REBOOT, 0))


	{


  TCHAR errmsg [MAX_ERRSTRING + 1];




  dwerr = GetLastError();




  if (0 < _sntprintf(errmsg, MAX_ERRSTRING, _T("Err: 0x%08X"), dwerr))


  {


 	 MessageBox(NULL, errmsg, _T("quickreset"), MB_OK | MB_ICONEXCLAMATION | MB_TOPMOST);


  }


	}




	return dwerr;


}[/code]

[Guest Soyale]

Thanks for that. I wasn't aware of that API!

[Guest caio1]

@rcraswell

thanks for that app!!!

Caio

[Guest nickcornaglia]

Just posted the question in the software forum and someone referred me here. Thanks!

[Guest Simon Desser]

Nice work :!:

Hope this doesn't sound picky, is there any way that an icon can be assigned to the exe, so it looks pretty in my menu :?: :) I hate those blue & white windows "icons"

[Guest dinoalbert]

Yikes! my skin returned to the default one, customized non-standard screen skins (incoming call, alert, question, information, exclamation, etc), system sounds and ringtones didnt work after I resetted using this app. Is this normal?

And then I cannot find any program/apps/games listed in the Remove Programs...how can I remove/uninstall programs now?

[Guest Soyale]

Hmmm. This is different from my experience of registry corruption caused by resets. I have seen this but caused by other things.

[Guest rcraswell]

Just updated it to include an icon per request. (Icon image shamelessly stolen from the phpBB emoticon list...)

In proper versions of Windows, there is a pair of messages (WM_QUERYENDSESSION and WM_ENDSESSION) that get broadcast when ExitWindowsEx gets called. I haven't checked to see if this happens on Smartphone but, since they're not documented, nobody's going to be looking for them anyway. So yes, when the phone resets, all apps probably just get the rug pulled out from underneath them.

[Guest nickcornaglia]

I don't know if this is related to dinoalberts problem but my phone reset as well. I had made a registry tweak, trying to restore my call.gif image, while IA CallerID was still on the phone and I thought that caused the problem. But I did use your app after changing the registry to reset and for the changes to kick in.

My phone reset to the original configuration.

I lost all of my settings.

I lost all of my IPSM Application Data.

I did not lose my installed software. Most was installed on the SD Card but the icons were still in the start menu. My start menu had catagorized folders for my apps that were now gone though...so that part seems inconsistent.

Do you think they are related?

[Guest gladel]

FWIW, here's a little applet that just calls the OS function directly.  Unsigned, decert, blah blah blah...

Update: added an icon per request

do u have an installable cab file for this?
