sample

问题 I need a fast method to store all samples of a wav file in an array. I am currently working around this problem by playing the music and storing the values from the Sample Provider, but this is not very elegant. From the NAudio Demo I have the Audioplayer Class with this Method: private ISampleProvider CreateInputStream(string fileName) { if (fileName.EndsWith(".wav")) { fileStream = OpenWavStream(fileName); } throw new InvalidOperationException("Unsupported extension"); } var inputStream =

问题 This question already has answers here : An error was encountered while running (Domain = LaunchServicesError, Code = 0) [duplicate] (31 answers) Closed 4 years ago . The watchkit sample app didn't start. The message was "The operation couldn’t be completed. (LaunchServicesError error 0.)". The sample app is "WatchKitCatalogUsingWatchKitInterfaceElements", which I got from the Apple Developer library. I tried to reset the contents and settings of the iOS simulator. Any ideas would be greatly

问题 This question already has answers here : generate random integers between two values with a given probability using R (2 answers) Closed 6 years ago . I need to get out a sample of subjects from a list to assign them as a Control Group for a study which has to have a similar composition of variables. I am trying to do this in R with the sample function but I don´t know how to specify the differetnt probabilities for each variable. Lets say I have a table with the following headers: ID Name

问题 Given a string of length n , how would I (pseudo)randomly sample m substrings of size k such that none of the sampled substrings overlap? Most of my scripting experience is in Perl, but an easy-to-run solution in any common language will suffice. 回答1: If there is a character that cannot occur in the input, e.g. X , just: my $size = 20; my $count = 20; my $mark = 'X'; my $input =

问题 I ve been searching a good simple sample for WF4 (or higher) state machine with resume (possibly BookMarks from the docs I ve read). I would like to see how can I implement a state machine that is able to resume at any given state inside a WF. Since I don't know anything about WF, I would like to see a simple state machine where I can resume the exceution at the state it was last time and it would also be nice to see how to 'force' a WF to jump to a state and re-start from there (if possible)

问题 could you guys point me to some really simple silverlight or wpf sample project where the usage of the MVVM is showed 回答1: Have a look at Josh Smiths article and app in MVVM WPF, or have a a look at Sacha Barber's application Cinch V.2, again, a really good app with brilliant explanations. I reckon start with Josh smiths and then on to Cinch. 回答2: http://www.vertigo.com/familyshow.aspx 回答3: Disclaimer: These are some MVVM examples I have built... Here is a Twitter search app example showing

问题 I was using the PrintSample and successfully modified the BasePrintPage code to the following (just trying to cut it down to a manageable size and the simplest case for testing): protected PrintDocument printDocument = null; protected IPrintDocumentSource printDocumentSource = null; internal List<UIElement> printPreviewElements = new List<UIElement>(); protected event EventHandler pagesCreated; protected void PrintTaskRequested(PrintManager sender, PrintTaskRequestedEventArgs e) { PrintTask

问题 It is my first time to make a Unit testing so i'm trying to find references to how to make a Unit testing of a DAO. Can you guys make a simple example of the setUpBeforeClass , setUp and how to test a method that inserting new data in database using model for this . Just a simple example using easy mock. Thank you for your consideration 回答1: The idea of using mock objects to perform your unit testing strikes me as peculiar as all you are doing is testing your mock objects instead of your real

问题 I cloned the Git Hub repo and imported the folder into eclipse. I attempted to run all of the samples on my Samsung Galaxy Skyrocket with CM10 and all the apps failed. I then ran it on a stock Galaxy S3 with stock ICS and a Samsung R720 with stock gingerbread and they all failed the same way. I finally ran it on the emulator for the same results. Below are the details of the failures Example: SplashActivity: Unfortunately Facebook SDK has stopped working immediately Tests: App runs but errors

问题 I was wondering if there was somewhere I could get some starter kit / theme sample for ASP.NET. I am not a designer, but I need to build a prototype for a project, and if I do it myself it'll certainly be awful Do you know where I could find that (ASP.NET specific)? 回答1: Check http://asp.net. There are quite a few starter kits and sample projects there. (http://www.asp.net/community/projects/) 回答2: Do you mean templates for a website? If so, that is nothing to do with ASP.NET, There are loads
