멜론 윈도우폰 8 이 끝난후에 했던 WINRT (windows 8) APP 프로젝트 이다.

 

윈도우폰 하고 있다가 윈도우8 개발자가 회사를 그만둠으로써 내가 맡았던 프로젝트 이다.

 

버그가 많아서 고치는데 죽는줄 ㅠㅠ

 

LTE 단말 대응이라든지 추가 UI및 기획 변경사항 버그 수정을 하느라 시간이 조금 걸렸던 프로젝트이다.

com error나 thread error가 나는걸 보니 분명히 dispatcher 를 쓰면 될꺼 같은데 라는 생각이 들었다.

 

networkchanged이벤트를 받아서 인터넷이 끊겼을때 ui를 변경 시켜야하는건데

 

networkchanged이벤트를 app.xaml에서 주는걸 그대로 쓰지말고 해당 xaml.cs에 한번더 이벤트를 건후

 

Windows.Networking.Connectivity.NetworkInformation.NetworkStatusChanged += delegate { DownloadNetworkState(); };
 
        private async void DownloadNetworkState()
        {
            await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
            {                
                MelonAppBar.SetDownloadToogleButtonContent();
            });
        }

 

 

이렇게 dispatcher를 이용했다…

 

근데 Windows.current.dispatcher는 쓰임이 다르니 다를때 사용할것(이것때문에 삽질 했다는 ㅠㅠ)

void detectScreenType()
 {
     double dpi = DisplayProperties.LogicalDpi;
     var bounds = Window.Current.Bounds;
     double h;
     switch (ApplicationView.Value)
     {
         case ApplicationViewState.Filled:
             h = bounds.Height;
             break;
 
         case ApplicationViewState.FullScreenLandscape:
             h = bounds.Height;
             break;
 
         case ApplicationViewState.Snapped:
             h = bounds.Height;
             break;
 
         case ApplicationViewState.FullScreenPortrait:
             h = bounds.Width;
             break;
 
         default:
             return;
     }
     double inches = h / dpi ;
     string screenType = "Slate";
     if (inches < 10)
     {
         screenType = "Slate";
     } else if (inches < 14) {
         screenType = "WorkHorsePC";
     }
     else 
     {
         screenType = "FamilyHub";
     }
     ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
     localSettings.Values["screenType"] = screenType;
 }

 

머 거창해 보이지만 실제로는

 

var bounds = Window.Current.Bounds;

 

이렇게만 얻어오면 된다.
