问题 I have already designed a back button and a forward button with xaml. When I click the back button, my FM radio instance should start looking for a radio frequency below the radio frequency according to signal strength. 回答1: hi there is code to do that private void FastForwardButton_Click(object sender, RoutedEventArgs e) { try { do { ManageFrequencyChange(0.1); } while (FMRadio.Instance.SignalStrength * 100 < 65); } catch (RadioDisabledException ex) { } } and refrence for these private void

How do you find the Main Window thread in UWP?

由 六眼飞鱼酱① 提交于 2019-12-08 10:10:10
问题 I have a library that needs to call the main windows thread in UWP when it receives a message from a communication channel (let say, a message indicating a check box should be checked). The library saves a copy of the SynchronizationContext when it starts up, so it can Post back to it when the data comes in, but the trouble is, I'm not guaranteed that the caller of this library is on the main thread when it's initialized. Is there some simple, guaranteed way to obtain the Main Window Thread

UWP MapControl: MapElement fixed heading

由 那年仲夏 提交于 2019-12-08 09:54:52
问题 I'm adding a MapElement to my MapControl but when I rotate the MapControl, my MapElement rotates along with it. Is it possible to have a fixed heading on the element? I've tried using a RotateTransform on the MapElement but the Element seems to just completely disappear. I'm using the following code: Also, the <Planes:Airplane /> object is just a custom drawn path. <Maps:MapControl x:Name="Map" Style="None" Grid.Row="2" TiltInteractionMode="GestureAndControl" ZoomInteractionMode=

Can't get current location when offline Windows 10 App?

由 ≡放荡痞女 提交于 2019-12-08 09:21:34
问题 I'm trying to find out whether it's possible to get the current location of a Windows 10 device if it's not connected to the internet via Wi-Fi (Wi-Fi) is disabled . I'm aiming this at Windows 10tablets and I don't think they all support GPS. Does anyone know what would be the best way to go about this? Or is it possible at all? when i use Geoposition pos = await geolocator.GetGeopositionAsync(); it returns Exception . 来源： https://stackoverflow.com/questions/33391228/cant-get-current-location

UWP App Upgrade Approach - Without Losing User Data

由 蓝咒 提交于 2019-12-08 09:03:37
I have a UWP app deployed to the Microsoft Store, and in use. It's a hobby project, available for free, and although I will update it now and then such updates will probably be infrequent. I'm about to release a new version to the store - it will be the first time I have done this. The app includes a SQLite database, which is created at runtime (so not part of the solution / source code). Update : the folder this ends up in is: C:\Users\...\AppData\Local\Packages\[Package ID]\LocalState I'd like to release a new version without having the user lose their existing data in the database. What's
