问题 I am fairly new to Windows Phone development, and I have a lot of classes that I thought would be straightforward by using some function in System.Web (namely, HttpUtility.ParseQueryString ). But it seems that System.Web is not available on Windows Phone ? Is this correct? Or might I just be missing a way of adding it? I'd really like to not have to hand write functions like ParseQueryString . Any advice on how to get a reference to System.Web in my Windows Phone app? Cheers! Brett 回答1: It

问题 Is there any way to create a project/application which will have multiple targets. Its same as how we create multiple targets for an iPhone application in XCode. Basically I have an app which has to be made for different targets, with almost all the similar functionalities but with little change. 回答1: You can use Configuration Manager to add additional configurations to the list of Debug and Release. Then for each configuration go to Project/Properties/Build/Conditional compilation symbols

问题 Is there a way to hook to scroll event in WPF (Windows Phone7), in a MVVM manner? I'd like to detect when the list is scrolled to the bottom, and then do something.

问题 How can I access to input data from microphone in Windows Phone 7.0 or 7.1? (like a Volume Meter), i want to detect start and end input data from microphone. 回答1: Have a look at How to: Access the Microphone in a Silverlight Application for Windows Phone for basic usage.

问题 what is the difference between mutex and monitor implementation. Can any one please help me to learn both of these for wp7(implementable code for wp7). Please try to add some code snippets that help me to understand the techniques in a simple way. Thanx in advance Stezma 回答1: A mutex can lock across multiple processes.

问题 I recently completed a library for a online storage website that allows for me to call the PHP exposed RESTs between the file storage website and a windows form desktop client + Outlook add in. Now, here is a question that has the code sample for the most basic operation in the library: Gracefully killing a TPL Task. I'm linking it for reference only. My next objective is a Windows Phone 7 client. I knew I simply cannot use the same library as I need a different kind of class library for a

问题 I am getting this weird error when making a WP7 app, and I can not see why. The only output/ error message I get is "UnhandledException: The parameter is incorrect. : : : ProgramName.App" This error occurs randomly, and I do not get any information from the debugger on how to resolve it. When I run the same code twice, one time it gets the error, and the other time it does not. So, have any of you got this error before, and can maybe tell me why it is happening? This is so frustrating,
