问题 I am porting some C# .Net code to WinRT and I am having trouble figuring out how to replace the following: bool threadDone = false; Thread updateThread = null; void StartUpdateThread() { threadDone = false; updateThread = new Thread(new ThreadStart(SendUpdateThread)); updateThread.Start(); } void StopUpdateThread() { if (updateThread == null) return; threadDone = true; updateThread.Join(); updateThread = null; } void SendUpdateThread() { while(!threadDone) { ... Thread.Sleep(...); } } What is

问题 I'm attempting to send a set of emails in a App store app using var mail = new Uri("mailto:test@somedomain.com"); await Windows.System.Launcher.LaunchUriAsync(mail); the email client starts but only the last email is displayed. I really need to "queue" the emails to the client. Is this possible? It has been suggested to use a share contract, but I assume I may have to prompt the user to share each email? Note: I'm sending multiple emails to multiple recepients, not email to multiple

问题 I'm trying to use BluetoothLEAdvertisementWatcher to detect BLE advertising packets. However upon calling Start() the watcher object always aborts with 'Access is denied' error. Code is pretty simple and is as below: auto filter = BluetoothLEAdvertisementFilter(); auto advert = BluetoothLEAdvertisement(); advert.LocalName(L"Greeny"); filter.Advertisement(advert); m_watcher.AdvertisementFilter(filter); // setup event handlers m_watcher.Received({ this, &MainPage::OnAdvertisementRecieved }); m

问题 This seems to be a simple task, yet my research left me with nothing: How do you extract items from a ZIP archive in a native Windows Runtime component (or application)? Now if I were to target .NET, there's a ZipArchive and ZipFile class, that make the solution as simple as it should be. But what, if I cannot or do not want to take a dependency on the CLR? The only compression support I was able to find in the Windows Runtime is the Windows.Storage.Compression Namespace, and there's really

问题 When a user takes a certain action a call (get) to a web service is made. The service doesn't allow for calls more frequent than once per second. I was thinking I could use Task.Delay to control this so that subsequent calls are made at least one second apart in time but it doesn't seem to work as expected. The pseudo-code looks like this: public async void OnUserAction() { var timeUntilPreviousCallWillBeOrWasMade = 1000ms - (Now - previousWaitStartTime); var

问题 i have a problem while navigating between pages of my app. Going from page "a" to page "b", i see a black screen just a second before seeing the page "b". It also happens in the opposite navigation. I know this issue is quite common, also here, but i don't understand how to solve it...and it's very ugly to view... EDIT: just an important information: i've set a custom image as background of both the pages(a,b)...as you can see in the code "Assets/Page.jpg" Here is my basic page "a" XAML:

问题 I trying to get my GPS position from a Desktop app, using Windows Runtime, in C#. I followed this how-to to set up Visual Studio and this code sample to create the following trivial code as a C# console app : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; using System.Threading.Tasks; using System.IO; using System.Runtime; using System.Windows; using Windows; using Windows.Devices.Geolocation; using Windows.Foundation; using
