mixing

问题 I have to integrate a large Java library in a quite large C++ application. A solution is to use JNI but this requires to hand code all the classes. Python has, for example, a wonderful solution with JPype (http://jpype.sourceforge.net/) that automatizes the process (although the same solution cannot be applied to C++ due to C++ and Python different natures). Thanks, Das 回答1: SWIG is a tool that lets you auto-generate bindings from one language to another. It supports C++ and Java and a dozen

问题 Introduction This post is about mixing Microsoft MVC helpers with native jquery ajax. The main problems i encountered along the way were: Double post submissions @Html.ValidationMessageFor not outputting attributes Requirements I have a requirement to validate and post a form (id = "my-form") The form is bound to a model decorated with validation attributes so I want to make use of helper methods such as @Html.ValidationMessageFor to harness unobtrusive benefits I need both client side and

问题 Here's what I'm working with right now: for (int i = 0, numSamples = soundBytes.length / 2; i < numSamples; i += 2) { // Get the samples. int sample1 = ((soundBytes[i] & 0xFF) << 8) | (soundBytes[i + 1] & 0xFF); // Automatically converts to unsigned int 0...65535 int sample2 = ((outputBytes[i] & 0xFF) << 8) | (outputBytes[i + 1] & 0xFF); // Automatically converts to unsigned int 0...65535 // Normalize for simplicity. float normalizedSample1 = sample1 / 65535.0f; float normalizedSample2 =

问题 I'm trying to solve a problem with WebRTC Native Android. I've successfully adapted the AppRTCDemo from a 1-1 call to 1-N calls. Currently I have the following scenario: A (me) can talk to/listen to B A (me) can talk to/listen to C B and C can't talk to or listen to each other. To accomplish that I (A) have 2 PeerConnections respectively with B and C. I understand I need to mix some how the media streams or audio tracks, or in other words: Mix (A, B) -> send to C Mix (A, C) -> send to B Any

问题 I am having trouble with the design of my code. I have 3 buttons not in a button group. I want to - based on the selected button - perform an action. Now the action requires a modification of an object in the class. This means i cannot use an inner class because this does not have access to the outer. If i could add an event listener to a button group this would be much easier but as i see it i will need an event handler for each radio button, is this correct? If not how else can i do it?

问题 I'm trying to develop an Android aplication that uses some sounds and mix them together for creating music compositions. At the beggining I tried just to reproduce sounds at the same time, but when I was doing that, they got disinchronized, and after several hours reading forums I realized that the best way to reproduce several sounds at the same time in loop mode is just to merge the audio files in one and then reproduce them as a single file. Here is the code I'm using: //Oppening file 1

问题 Is using C in C++ bad? Many people have told me that using C in C++ is bad because it's not as safe, and it requires more memory management. I keep telling them that as long as you know what you're doing, and you delete your "new"s and free your "malloc"s then C isn't a problem. I'm currently on a forum where an argument over std::string vs. a char* is taking place. Some people are saying that allocating a simple char* memory block is more efficient, and as long as you deallocate it, it's

问题 is there a simple way to combine two customized Java LookAndFeel classes? I want to use the Nimbus class for its theme (fonts, rounded edges, etc), but with the colors from the Metal class. Short of writing my own customized look and feel class from scratch, I am just wondering if there is a simpler way first. I see that this guy here: Mixing look and feel has customized just a border, but I would like to be able to do this for all the colours. is this possible or would it take just as long

问题 I checked the following article in which it presented the following mixing: rem font size with pixel fallback @function calculateRem($size) { $remSize: $size / 16px; @return $remSize * 1rem; } @mixin font-size($size) { font-size: $size; font-size: calculateRem($size); } I feel very confortable using rem on my projects, after placing font-size: 62.5% on the html so 1rem = 10pixels . But I would like to know if there is a mixing or a method to create a pixel fallback for any rem used in a whole

问题 I am using JPA/Hibernate to call simple CRUD queries (create, update, findByXAndYAndZ...). However, as I know, JPA doesn't support well on calling stored procedures and batch insert/update, so I consider using old JDBC to do that (like this link: http://www.java2s.com/Code/Java/Database-SQL-JDBC/BatchUpdateInsert.htm). I just wonder if it causes any problems when I mixing JPA and JDBC. Hope that you may share some real-world experiences on this issue. Thanks. UPDATE: I have tried the Spring
