问题 I currently have a windows phone 8 application that has a user control that is bound to some view model. In the view model I a have a command property that binds to a button on the view. I want to popup a message box in the view that asks "Are you sure you want to do X?". If Yes it needs to fire the command that is bound to the button else it needs to not fire the command. I obviously do not want to fire the MessageBox from the view model since this is view logic. So how do I show the

问题 I am trying to figure out, how to set the app logo as well as the splashscreen using the preview for cordova apps (or Multi-Device Hybrid Apps) in Visual Studio 2013. I tried adding <platform name="wp8"> <icon src="img/logo.png" width="99" height="99" /> <!-- tile image --> <icon src="img/logo.png" width="159" height="159" /> </platform> However this won't do the trick. It's a pretty new thing so finding informations on this topic is kind of hard. It was pretty easy, using the old method. Any

问题 I'm familiar with C#, but this is my first Windows Phone application so I don't really know what I'm doing. I have a few images (I assume this is the picturebox equivalent from form applications?) on my designer, but when I run it in the emulator they do not show up. Here is my code: <Image HorizontalAlignment = "Left" Height= "14" Margin="10,42,0,0" VerticalAlignment = "Top" Width = "14" Source="/Resources/Blackbox.png" Visibility = "Visible"/> I'm probably missing something very obvious.

问题 I am just setting up in-app purchasing within my app .. it will be a single 'Durable' item that I am allowing the users to purchase. I have got it going in testing with the MockIAP project, but it does raise some questions. My Durable purchase will be an 'upgrade to pro' so I named the key as 'ProUpgrade' within the mock initial setup. when I go to purchase the product within my app, the message asks if I want to buy (ProUpgrade). Is this the only name/description that is visible to the user?

问题 I've studied the Windows ChatterBox sample app for Windows Phone 8 and I was able to write a small app to try out PJSIP. However I've run into a problem with the CallInProgressAgent. When creating an outgoing call, I create a VoipPhoneCall object by calling the RequestOutgoingCall method on the VoipCallCoordinator class, thereafter I create the pjsip call by using the pjsua api. It seems pjsip looses all rtp connectivity as soon as I call the RequestOutgoingCall method. My guess is that pjsip

问题 I have a Windows Phone 8 app that will read a lot of HTML source from a website. The HTML source contains quite a bit of information, however the information I need is all stored in tr and td tags within the HTML like so: <tr> <td class="first"> </td> <td > Origin </td> <td> Airline </td> <td> Flight Number </td> <td> 22 Feb 11:50 </td> <td class="last"> Arrived 12:35 </td> </tr> I intially thought about using the HTMLAgilityPack but it doesn't seem to be supported on Windows Phone 8, at

问题 Is there any way I could change the Uris of the default tile images in the WMAppManifest.xml at runtime? For example I would like to enable an option for users to select the tile image in the settings of my app. This is not the problem because I can then update the main tile with the new image if the app is pinned to the start, but if the app is not pinned and the user wants to pin the app another time then the default image will be used, and this is not the behavior I want, I want the tile

问题 I've always used RestSharp to handle async requests on Windows Phone 7 & 7.8 applications, but today, I was trying to add RestSharp to a Windows Phone 8 application and it wouldn't work.
