问题 Is there a easy way to perform a method after a given delay like in iOS out of the box? On iPhone I would do this: [self performSelector:@selector(connectSensor) withObject:nil afterDelay:2.5]; It will then schedule the method connectSensor on the main thread (UI thread) to be executed after 2,5 seconds. And because it is automatically scheduled on the main thread, you don't have to worry about cross thread issues. (There is also a performSelectorOnBackground version) So how would I do this

问题 I want to develop mobile applications for the WINDOWS PHONE 7 using silverlight. Can anybody suggest me suitable tutorial please. Thanks in advance. 回答1: Well you should probably start at MSDN on the Phone Platform section. Then I would recommend you go and download the Windows Phone 7 Developer Training Kit which contains some introductory tutorials on getting started with WP7 and building your first app. From there you can check out a couple of different things like the following: This

问题 For windows phone app, when I am adjusting brightness by slider it works fine when I move it to right. But when I go back to previous position, instead of image darkening, it goes brighter and brighter. Here is my code based on pixel manipulation. private void slider1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e) { wrBmp = new WriteableBitmap(Image1, null); for (int i = 0; i < wrBmp.Pixels.Count(); i++) { int pixel = wrBmp.Pixels[i]; int B = (int)(pixel & 0xFF); pixel

问题 I need to get the installed apps of a Windows Phone. Do you know if this is available from the SDK? 回答1: It's possible to list third party applications installed on the phone, but only from your desktop machine (ie. not from an app running on the device) and thus might not be what you are after. Firstly, you need to add a reference to this assembly: c:\Program Files (x86)\Common Files\microsoft shared\Phone Tools\CoreCon\10.0\Bin\Microsoft.Smartdevice.Connectivity.dll Then the following code

问题 I'm using a WebClient to get infos asynchronously from my web service : wc.DownloadStringCompleted += DownloadStringCompleted; wc.DownloadStringAsync(service); I works fine, but I think the DownloadStringCompleted method is working on the UI Thread, and since i'm doing a lot of parsing there, my page takes a few seconds to appear. However, since I have so fixed data and a progress bar, I would'nt mind have it appearing instantly. How could I perfom this ? Thanks ! 回答1: Use HttpWebRequest

问题 my application, currently, goes to the MainPage.xaml at startup (I don't know where it has configured though). I want to be able to start with another page in some conditions. I think I can add this code to Application_Launching() in App.xaml.cs page: NavigationService.Navigate(new Uri("/SecondPage.xaml", UriKind.Relative)); but NavigationService is not available in App.xaml.cs. How can I start the application with another page if foo == true ? 回答1: Changing start page in App.Xaml.cs :

问题 I'm developing an app for Windows Phone 7 and I'm using a Phonegap template for it. Everything looks perfect, but now I’m stuck trying to open a PDF file in the browser. I tried the following but that doesn’t work because the url of the PDF exceeds the 2048 character limit (it’s a data url). This code runs after the deviceReady event was fired. var ref = window.open('http://www.google.com', '_blank', 'location=no'); ref.addEventListener('loadstart', function () { alert(event.url); }); Now, I
