Android widget refresh not working -

-

my widget should refresh textviews every day @ 0:00. in widget_provider.xml set android:updateperiodmillis="1000" read minimum update period 30 minutes , have use alarmmanager this. want alarm triggers refresh every day @ 0:00. updateservice.class handles refreshing (setting texts textviews based on date. class not called until around half hour after midnight)

in public void onupdate(context context, appwidgetmanager appwidgetmanager, int[] appwidgetids) method using code:

 intent intentn = new intent(context, updateservice.class);  pendingintent pendingintent = pendingintent.getbroadcast(context, 0, intentn, pendingintent.flag_update_current);  calendar calendarn = calendar.getinstance();  calendarn.settimeinmillis(system.currenttimemillis());  calendarn.add(calendar.hour_of_day, 20);  calendarn.add(calendar.minute, 44);  calendarn.add(calendar.second, 5);  alarmmanager alarmmanager = (alarmmanager)context.getsystemservice(context.alarm_service);  alarmmanager.setrepeating(alarmmanager.rtc_wakeup, calendarn.gettimeinmillis(), 7000, pendingintent);

(i trying actual time now)

is right place code? why doesn't work? using toast messages in updateservice.java, never toast in onstart(intent intent, int startid) method apart first time, when app in installed.

thanks in advance

update

with of probablykevin, rewrite code. tried code out in activity , works:

   intent myintent = new intent(mainactivity.this, updateservice.class);         pendingintent pendingintent = pendingintent.getservice(mainactivity.this, 0, myintent, 0);                   alarmmanager alarmmanager = (alarmmanager)getsystemservice(alarm_service);                  alarmmanager.cancel(pendingintent);                  calendar calendar = calendar.getinstance();                  calendar.settimeinmillis(system.currenttimemillis());                  calendar.add(calendar.second, 10);                  alarmmanager.setrepeating(alarmmanager.rtc_wakeup, calendar.gettimeinmillis(), 8000, pendingintent);         toast.maketext(mainactivity.this, "start alarm", toast.length_long).show();

however if modify appwidgetprovider class (and put there ofc) not work. never toast msg:

 intent myintent = new intent(context, updateservice.class);          pendingintent pendingintent = pendingintent.getservice(context, 0, myintent, 0);                    alarmmanager alarmmanager = (alarmmanager)context.getsystemservice(context.alarm_service);                   alarmmanager.cancel(pendingintent);                   calendar calendar2 = calendar.getinstance();                   calendar2.settimeinmillis(system.currenttimemillis());                   calendar2.add(calendar.second, 10);                   alarmmanager.setrepeating(alarmmanager.rtc_wakeup, calendar2.gettimeinmillis(), 8000, pendingintent);          toast.maketext(context, "start alarm", toast.length_long).show();

first, repeating time should 24 * 60 * 60 * 1000, in milliseconds. second start time found using time left until next 0:00:

final long millis_in_day = 24 * 60 * 60 * 1000; long timeuntilmidnight = millis_in_day - (system.currenttimemillis() % millis_in_day);

then set alarm adding time left current time:

alarmmanager.setrepeating(...system.currenttimemillis() + timeuntilmidnight, millis_in_day...);

make sure don't set multiple of same alarm. call

alarmmanager.cancel(pendingintent);

before setting again sure.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
