compatibility

问题 I am writing a Java applet and embedding it in a web page. It used to run Mac and Windows in different browsers without problem. I was using NetBeans on the Mac to build the .jar file the applet used. For some reason or another I decided to load the project on the Windows' NetBeans - I started getting the following error on the Windows machine when accessing the web page from any browser: java.lang.ClassFormatError: Incompatible magic value 1008813135 in class file Fearing that it must have

问题 In one of the comments in this question, it was brought out that initializing C++ pointers by default would break compatibility with C. That's fine, but why would something like this matter? I would think the only time it would actually matter is if I wanted an uninitialized pointer for some reason. But I can't think of a reason why I would want to have that. Is there a use for uninitialized pointers? Or is the compatibility issue merely one of compatible behavior (i.e., not increasing

问题 Introduction This post is related to this one here. I was desperately trying to migrate an app from my organization server to my local machine just to explore the code and get my hands on. This is my first time getting familiar with Tomcat and java servlets things, hence it is a newbie talking to you here. My tries was with tomcat version 7.0.93. and tomcat 8.0.35. With tomcat 8.0.35, the app opens but crashes in the login screen, I guess. With tomcat 7.0.93, the app did not start at all, the

问题 There is this warning kind of message when compiling mexFunction files using the mex command in Matlab 2014b. Legacy MEX infrastructure is provided for compatibility; it will be removed in a future version of MATLAB. What is this supposed to mean? There comes a link with this message, but I did not find something useful. Also this question did not make me more wise. Will the MEX API vanish? Will there be a different interface? What is going to change exactly? Can anybody tell? 回答1: The

问题 With an effort, I wrote a demo which can record a h264/aac video successfully. I use MediaCodec and MediaMuxer which are both available since api-18. To avoid that the color formats for the camera output and the MediaCodec encoder input are different, I chose the color format "MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface" according to the continous capture activity of grafika. But I am worrying about one thing, there are so many kinds of Android phones, Can my demo record video

问题 I've been supplied a web service by a colleague that I tested by creating a quick .net 3.5 project. the service exposes a simple method that returns a DataTable and everything works just fine. The production project is .net 1.1, though, and I get a runtime error on the line that creates the web service object: The XML element '' from namespace 'web/InternetData' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element. Description:

问题 I have set minSdk to 7 and targetSdk to 17. I find the problems by manually checking if something crashes. (Yes this is nonsense) I tried setting targetSdk to 7 too. But that doesn't help either. I think I am missing a setting which still thinks that the target is 17. How can I be sure that I am not using any incompatible code? I at least need warnings. For sure I check for build version to dynamically call higher level APIs or not, but I want to be sure that I have surrounded any possible

问题 I have a custom installer application built with C++/ATL. The application's target platform is XP3, VS solution consists of static lib and exe projects.
