Hello

Is it really not possible to perform a hardreset with newer devices using
..NET CF?

Thanks

Rampf
 
Has nothing to do with CF or native code. If the OEM provides a capability
to do it, then you can. If they don't you can't. Can't see really any good
reason for an application to ever hard reset - that would effectively erase
the application itself - unless you're in ROM, and in that case you're
probably the OEM and you'd have a hook to do the hard reset anyway.

Thanks Chris

It would be a security feature for our devices to remotly wipe the device....

You'll have to speak to your device manufaturer on which you are
supporting your application to provide you API to hard reset the
phone. There is a way to do it but i think this won't work on all the
devices.

try following if it helps you.

SetCleanRebootFlag();
KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);
 
As Chris said, the OEM has provide capability to do it. SetCleanRebootFlag()
will work in the emulator but not in most devices (especially device running
WM5)

In Windows Mobile 6 you can use the RemoteWipe CSP. P/Invoke
DMProcessConfigXML from aygshell.dll and pass this:

<wap-provisioningdoc>
<characteristic type="RemoteWipe">
<parm name="doWipe" value="1"/>
</characteristic>
</wap-provisioningdoc>

as the XML configuration data. If the app is trusted then the device will
immediately do a cold reboot after executing the command.

Here's an MSDN link to DMProcessConfigXML

No need to platform invoke DMProcessConfigXML from WM5 and onwards as its
supported with this method:
Microsoft.WindowsMobile.Configuration.ConfigurationManager.ProcessConfiguration()
