I've been struggling with this for quite some time now and I couldn't find a working solution. I have a wav file (16 bit PCM: 44kHz 2 channels) and I want to extract samples into two arrays for each of the two channels. As far as I know the direct method for this does not exist in NAudio library, so I tried to run the following code to read a few of interlaced samples but the buffer ar
我一直在努力争取相当一段时间,我找不到一个可行的解决方案。 我有一个wav文件(16位PCM:44kHz 2通道),我想为两个通道中的每一个提取采样到两个阵列。 据我所知,在NAudio库中不存在这种直接方法,所以我尝试运行下面的代码来读取一些隔行样本,但缓冲区数组保持空白(只有一堆零): using (WaveFileReader pcm = new WaveFileReader(@"file.wav")) { byte[] buffer = new byte[10000]; using (WaveStream align
I have just started working on an MVC project and things are going ok but it looks like I am creating alot of spaghetti code with just too many objects. Can anyone see how I can simplify this solution before the whole projects gets out of hand? ok, here's my set up: DAL - has Entity framework connections and methods to obtain data then convert the data to my model objects in the model la
我刚刚开始研究一个MVC项目,事情会好起来的,但它看起来像是我用很多对象创建了许多意大利面条代码。 任何人都可以看到我可以在整个项目失控之前简化这个解决方案吗? 好的,这是我的设置: DAL - 具有实体框架连接和方法来获取数据,然后将数据转换为模型层中的模型对象 BLL - 将数据发送回UI模型 - 这包含整个站点使用的所有模型对象,通过创建新对象然后填充变量将来自DAL的任何内容转换为这些对象。 用户界面 - 我
I am working on a embedded system. We have limited stack and heap in our embedded system typically 64k (ram). I am trying to use polar-ssl library calls. Is there any tools which tells how much stack and heap memory is used by a C function? Is there any option is in valgrind which prints the following: Stack and heap usage of a function. Call trace of functions which calls internally mal
我正在研究嵌入式系统。 我们的嵌入式系统中堆栈和堆栈有限,通常为64k(ram)。 我正在尝试使用polar-ssl库调用。 是否有任何工具可以告诉C函数使用多少堆栈和堆内存? valgrind中是否有任何选项可以打印以下内容: 堆栈和堆使用函数。 调用内部malloc调用没有字节的函数的跟踪。 有一个valgrind工具地块可以测量应用程序使用多少堆内存。 同样的memcheck可以给你堆栈跟踪。 这里有更多解释 http://wiki.eclipse
I have implemented the MVP pattern in a few WinForms applications that uses a passive view. I implement an interface containing properties and delegates in the form of Action< T > and Func< T > to wire up UI events in concrete views and call back to the presenter. I am about to start a new project and did a little research into the pattern online including the many examples of the
我在一些使用被动视图的WinForms应用程序中实现了MVP模式。 我实现了一个包含Action <T>和Func <T>形式的属性和委托的接口,以在具体视图中连接UI事件并回叫主讲者。 我即将开始一个新项目,并对在线模式进行了一些研究,包括模式的许多示例,并注意到所有人都使用EventHandler来通知演示者。 我不明白为什么会在这种情况下使用事件,因为我认为只有一个主持人的观点。 我的问题是,这是为了与.Net框架如何使
I am trying to use Rx to read from a TCPClient receive stream and parse the data into an IObservable of string, delimited by newline "rn" The following is how I'm receiving from the socket stream... var messages = new Subject<string>(); var functionReceiveSocketData = Observable.FromAsyncPattern<byte[], int, int, SocketFlags, int> (client.Client
我正在尝试使用Rx从TCPClient接收流读取数据,并将数据解析为由换行符“ r n”分隔的字符串IObservable。以下是我从套接字流接收的数据... var messages = new Subject<string>(); var functionReceiveSocketData = Observable.FromAsyncPattern<byte[], int, int, SocketFlags, int> (client.Client.BeginReceive, client.Client.EndReceive); Func<byte[], int, byte[]> copy = (b
In a portion of code I need to check if there are some errors on arguments function or if there is a fscanf failure. I have to set the errno value: I will set errno to EINVAL if there are problems with arguments. But what if i have a failure on fscanf ?
在一部分代码中,我需要检查参数函数是否存在一些错误,或者是否存在fscanf失败。 我必须设置errno值:如果参数有问题,我会将errno设置为EINVAL 。 但是如果我在fscanf失败了呢?
Using the following example i would like to use my Expression inside my Contains method, having it pass the query onto sql server using the EF . How can i build this up to work correctly? void Main() { IQueryable<Person> qry = GetQueryableItemsFromDB(); var filtered = qry.Filter(p=>p.CompanyId); } public static class Ext { public static IQueryable<T> Filter<T&g
使用下面的例子,我想在我的Contains方法中使用我的Expression ,让它使用EF将查询传递到sql服务器。 我怎样才能建立这个工作正常? void Main() { IQueryable<Person> qry = GetQueryableItemsFromDB(); var filtered = qry.Filter(p=>p.CompanyId); } public static class Ext { public static IQueryable<T> Filter<T>(this IQueryable<T> items, Expression<Func<T, int&
I have been working on allowing function chaining. I have created a class called continuationmonad which takes a value, and a function from a => b. This allows me to use fmap and bind to chain these together. I have also used lazy to allowed calls to be defered where possible. Is this class really the continuation monad or is it something else. I am finding it hard to find good literatur
我一直在努力让功能链。 我创建了一个名为continuationmonad的类,它接受一个值,并从a => b函数。 这使我可以使用fmap和绑定将它们链接在一起。 我也使用懒惰允许的电话在可能的情况下被打败。 这个类真的是继续monad还是别的东西。 我发现很难找到不是Haskell的优秀文献。 还有关于如何改进/纠正此问题的任何评论。 using NUnit.Framework; using System; namespace Monads { public class Continuation<I
Phishing question. I have a tcp server application that uses certificates for tls/ssl and stored in the pkcs#12 file. Assuming a CA is installed somewhere on the network and is accessible, would it be normal practice to request a ssl certificate from the CA (once), programmatically (C#) and write it out to the pkcs#12 file for use by the server. Would that be normal practice, or would the mo
网络钓鱼问题。 我有一个使用tls / ssl证书并存储在pkcs#12文件中的tcp服务器应用程序。 假设CA安装在网络的某个地方并且可以访问,那么通常的做法是从CA(一次)以编程方式(C#)请求ssl证书并将其写出到pkcs#12文件以供服务器使用。 这是否是正常的做法,或者更可能的情况是从Thawte或Versign等CA购买证书,特别为该客户购买证书,并预先创建pkcs#12文件,并将其作为安装过程的一部分进行安装。 我认为这是一个可以
Comparing string in C# is pretty simple. In fact there are several ways to do it. I have listed some in the block below. What I am curious about are the differences between them and when one should be used over the others? Should one be avoided at all costs? Are there more I haven't listed? string testString = "Test"; string anotherString = "Another"; if (testString.CompareTo(anotherSt
在C#中比较字符串非常简单。 实际上有几种方法可以做到这一点。 我在下面的部分列出了一些。 我很好奇的是它们之间的区别,以及什么时候应该用于其他方面? 应该不惜一切代价避免? 我还没有列出更多吗? string testString = "Test"; string anotherString = "Another"; if (testString.CompareTo(anotherString) == 0) {} if (testString.Equals(anotherString)) {} if (testString == anotherString) {} (注意:我
