  c++ visual-studio-2010 unit-testing boost boost-test
  I am using Boost.Test Unit Test Framework for native C++ projects. All is working fine, but I’ve got one issue after upgrading to Visual Studio 2010: The messages about failed tests are no more shown in the error list after the tests ran as a post build step. This is a pity since the combination of Boost.Test with native C++ project came closest (although still beeing far away) to the comfort I am used to from unit testing managed projects. I am using the configuration recommended by the authors

  c++ asp.net-mvc azure pinvoke
  I’ve found this says azure web/worker role can load native c++ dll. Does azure website also support this?My site is a mvc site that p/invoke a native c++ dll which read files from local drive and does some calculations. the reason i’d prefer azure website is because it starts from free.Thanks.

  c++ events dynamic-cast
  event is a highlighted keyword in MSVC++ Express 2008, and the following code is used in a framework:else if (dynamic_cast<simulation::AnimateEndEvent*>(event)) { … }What does it mean to dynamic_cast a keyword rather than a variable/object?

  For application build with latest NDK every touch event generates this error message in the application log:E/NativeActivity(20148): channel ‘425e6ad8/android.app.NativeActivity (client)’ ~ Failed toreceive dispatch signal. status=-11Is it a bug or may be something has changed in native input processing?

  c++ parsing http
  I’m trying to write a small c++ webserver which handles GET, POST, HEAD requests. My problem is I don’t know how to parse the headers, message body, etc. It’s listening on the socket, I can even write stuff out to the browser just fine, but I’m curious how should I do this in c++.Afaik a standard GET/POST request should look something like this:GET /index HTTP/1.1 Host: 192.168.0.199:80 Connection: keep-alive Accept: */* User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML,

  c# c++ .net-4.0
  I’ve got a C# application that calls a native C++ DLL (I control the source of both). I’ve used AllocConsole() from the managed side, and then call into the native side. But the native code won’t output to the console- nothing happens, even though there is most definitely a console available, since I just explicitly allocated one. The code works fine if I allocate a console before the first console output from the native code, but if I try to allocate a console during only some std::cout calls,

  c++ sockets tcp ip
  I have been learning how to program sockets, but when I try practice writing codes, I have some problems. The code works for connecting to computers on the same LAN but when I try to connect to two computers on a different network over the internet, I was unable to. Is this because of the program or is this because of network security?Where can I find more information on it if I want to make applications communicate over the internet. I was thinking of making a chat program so that I understandi

  java c++ linux jni tomcat5.5
  I have a problem where allocating to much -Xmx causes a problem of the most unusual kind.The Problem: Setting -Xmx to 3072m on a 32bit JVM on a 64bit Linux OS works except for one condition where a servlet attempts to communicate with many outside entities via JNI IPC. When we lower the -Xmx to 2048m it works. No errors within tomcat are ever seen. The only errors that are seen are within the JNI logging code. This leads me to believe that since this is a 32bit process, setting the max java heap

  windows svn config git-svn
  This is my first question here, I am not doing anything wrong.As the title suggests, I am trying to work with git-svn on a project which has a central SVN repository. The SVN repository uses auto-props, and if these are not properly set in the local SVN configuration file, the commit is rejected.I have read everywhere, including here on StackOverflow, that git-svn is smart enough to read and honor the svn configuration file, so if I already configured my Subversion client properly, git-svn shoul

  google-chrome html5-video mediaelement.js
  When I use MediaElement.js and list first the mp4 file and then webm, then it doesn’t play anything in Chrome (11.0.686.3 dev). It works fine in Safari/FF/Opera. It works fine in Chrome if I list mp4 first and webm second but don’t call mediaelementplayer, using native HTML5 video. It also works fine in Chrome (and others) if I call mediaelementplayer but list webm file first. I’ve tried all variations and can’t figure out this behavior. I got around it on by changing source order on server side
