c# - How to Toast Notification when win app is closed in WP8? -


i want implement toast , tile notifications. notification must meet criteria, such needs able run when app closed. example, birthday reminder can run in background when app closed.

sample found:

shelltoast toast = new shelltoast(); toast.title = "toast title: "; toast.content = "test"; toast.show();

the above example works when app running. here code:

    private void startperiodicagent()     {         // variable tracking enabled status of background agents app.         agentsareenabled = true;          // obtain reference period task, if 1 exists         periodictask = scheduledactionservice.find(periodictaskname) periodictask;          // if task exists , background agents enabled         // application, must remove task , add again update          // schedule         if (periodictask != null)         {             removeagent(periodictaskname);         }          periodictask = new periodictask(periodictaskname);          periodictask.expirationtime = system.datetime.now.adddays(1);          // description required periodic agents. string user         // see in background services settings page on device.         periodictask.description = "this demonstrates periodic task.";          // place call add in try block in case user has disabled agents.          scheduledactionservice.add(periodictask);     }    private void runbackgroundworker()     {         //phonecalltask calltask = new phonecalltask();         //calltask.phonenumber = "03336329631";         //calltask.displayname = "arslan";         //calltask.show();           backgroundworker backroungworker = new backgroundworker();          backroungworker.dowork += ((s, args) =>         {             thread.sleep(10000);         });          backroungworker.runworkercompleted += ((s, args) =>         {             this.dispatcher.begininvoke(() =>             {                 var toast = new toastprompt                 {                     title = "simple usage",                     message = "message"                 };                 toast.show();                 }         );         });         backroungworker.runworkerasync();     }

but don't notifications. can tell me how set notifications work when app isn't running?

backgroundworker different scheduled task schedule periodic running.

add windows phone scheduled task agent , in project write code logic invoke necessary calls producing toast.

protected override void oninvoke(scheduledtask task) {   ------------------------------------------------   code scheduled task running. }

once code has been completed, can call notifycomplete() indicate once work of scheduled task over.

whereas backgroundworker runs code in separate thread , there no correlation scheduled task other fact that; can use background thread in scheduled task.

in order logic shared across main application , scheduled task:- create separate project , put reusable/shared code inside it. refer in main app , scheduled task sharing/accessing variables.

make use of isolatedstoragefile , mutex in separate project , share dll across both

*random reference schedule task example: http://wildermuth.com/2011/9/6/periodic_agents_on_windows_phone_7_1*

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
