From: Peter Foot [MVP] on 8 Feb 2007 13:33 If you raise your notification using SHNotificationAdd you can pass a flag to force the screen on. But you'll need to P/Invoke the native APIs because the managed Microsoft.WindowsCE.Forms.Notification class doesn't support this flag.

hi all so i am here again... i don't have found how i can use the notification... but i have tried this: i call the setPowerrequirement to wake up the screen i change the batterytimeout value in the registry from 0 (setting by setpowerrequirement) to 0x1E the hex for 30 sec i flush the value in the key in this way the time out is set an other time to 30 sec but it seems that the OS recognize the change only when i close my application... so i call a releasePowerRequirement to the handle of the set power requirement and then i call a SystemIdleTimerReset in this way the change of the batterty timeout in the registry is recognized by the OS without closing the application.. i don't know why i need the last 2 call but all seems to run...hope this would be useful for someone if you have any suggest i am here |
