问题 How to change MediaCapture to byte[] in Windows Store App for Windows 8.1. From lib: Windows.Media.Capture.MediaCapture asd = new Windows.Media.Capture.MediaCapture(); Thans! 回答1: I assume you want to get a byte array from what the camera is seeing at the moment, although it's hard to interpret from your question. There is a sample on the Microsoft github page that is relevant, although they target Windows 10. You may be interested in migrating your project to get this functionality.

问题 I've got a Bootstrap dropdown in my app's navbar with some links in it. Some links have ng-click triggers attached while others are just regular links. The following code works fine on all major browsers on Mac OS 10.11 as well as on Windows 7. On Windows 8 it works in IE 11, but not in Chrome 48 (latest). In Chrome 48, clicking a link in the dropdown causes the dropdown to close, but the ng-click or link href is not triggered. There are no console errors and I've confirmed that there are no

问题 I am looking for a solution to send an escape sequence to a serial port in a windows store app. Maybe my understanding of windows store apps is wrong. I don't want to run this app on a windows RT device, but on a normal windows 8 PC. I know, that windows RT devices do only support very less communication with connected devices, but not serial ports. 回答1: Well, as I know it's not possible to do something like that by using WinRT library. It's sandboxed and you can't access lots of features

问题 When using my Windows Touch Device, holding down on an area results in a an expanding box appearing which extends to about two centimetres squared. Letting go will then result in the right click menu appearing. The problem is that I want to disable the box and the menu from appearing. I have managed to prevent the context menu from appearing, but I am still left with the box. I believe the box is interfering with other functionality I have on the page. Any help much appreciated, Thanks UPDATE

问题 I want to update my UI based on the scenario when an Ad is being shown or an error occurred. I am using AdRotator v2.1. Looking at the source code it seems that the control would collapse if it could not serve an ad from various provider, and the IsAdRotatorEnabled would be set to false. But that property does not trigger an notification change. How can i detect if no ads are being shown? Enabled="{Binding AreAdsEnabled,Mode=TwoWay,FallbackValue=true,UpdateSourceTrigger=PropertyChanged}" 回答1:

I am using a PushStreamContent in a Web Api controller to serve the data that's being requested using a GET operation.
