  • Strange fstream problem

    - by noname
    Hi, I have really strange problem. In Visual C++ express, I have very simple code, just: #include <fstream> using namespace std; int main() { fstream file; file.open("test.txt"); file<<"Hello"; file.close(); } This same code works OK in my one project, but when I create now project and use this same lines of code, no file test.txt is created. Please, what is wrong?¨ EDIT: I expect to see test.txt in VS2008/project_name/debug - just like the first functional project does.

  • Minimal Lunix distribution with sshd and apt

    - by Sergey Mikhanov
    When I signed up for my Debian Linux VPS hosting and first logged on and invoked ps aux, there was the only user process running: sshd. As I can see, this was minimal Linux with only two things installed and configured: sshd and apt (plus all dependencies, of course). I want to build (or use existing) similar Linux distro, any advice on how to build (or pick) one? Googling "minimum linux", or "linux with sshd only" usually brings up Debian's netinstall, which is not what I want. Thanks in advance.

  • Using MSpec runner in Visual Studio 2010 and .NET 4

    - by spapaseit
    Hi Everyone, I'm a big fan of MSpec so naturally I wanted to use is right away with VS2010 as well. I have the MSpec runner defined as an external tool in Visual Studio to be able to have it always visible as a toolbar item. Anyway, whenever I try to use the MSpec runner (mspec.exe) with a .NET 4.0 solution I get the following error: Could not load file or assembly 'file:///C:\Users\[SOMEUSER]\[SOME_FOLDERS}\bin\Debug\[PROJECT].Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. I can still run my specs with the Resharper 5 runner so it's no big drama, but I bothers me to no end :þ Do you guys have any idea what the problem could be? Is there any solution other than recompiling the whole Mspec source code as a .NET 4.0 solution, which I really, really don't want to do? Thanks in advance. Sergi

  • ActiveMQ & Camel - How to create dependency in routing paths

    - by CodeMedic
    I have a message routing to implement, which has routes that vary according to the message content. Some strands of the route are dependent on other. If for example I have Data_A which has Task_A and Task_B to be performed on it. Whereas Data_B has only Task_B to be performed on it. Here each Task has a queue served by consumers. If Task_A should be performed only after Task_B if Task_B is requested on the data, how do I set-up such dependencies?

  • Glew in VS 2010: unresolved external symbol __imp__glewInit

    - by NoviceCai
    I am learning OpenGL by following the redbook. When I come to around page 90, I need use glGenBuffers(); Then I need install "glew". By following the steps in www.cs.uiowa.edu/~cwyman/classes/common/howto/winGLUT.html I download glew.zip from glew.sourceforge.net/ and unpack the files. I put glew.h in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include and put glew32.lib in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib and put glew32.dll in C:\Windows\System32. After that, I build my project in VS 2010 and in Linker-input, I add dependencies glew32.lib. But when I build it, I have error unresolved external symbol _imp_glewInit I spend whole day to search solutions, but did not find one. Hope someone can help me with this.

  • Could Grand Central Dispatch (`libdispatch`) ever be made available on Windows?

    - by elliottcable
    I’m looking into multithreading, and GCD seems like a much better option than manually writing a solution using pthread.h and pthreads-win32. However, although it looks like libdispatch is either working on, or soon going to be working on, most newer POSIX-compatible systems… I have to ask, what about Windows? What are the chances of libdispatch being ported to Windows? What are the barriers preventing that from happening? If it came down to it, what would I need to do to preform that portage? Edit: Some things I already know, to get the discussion started: We need a blocks-compatible compiler that will compile on Windows, no? Will PLBlocks handle that? Can we use the LLVM blocks runtime? Can’t we replace all the pthread.h dependencies in userspace libdispatch with APR calls, for portability? Or, alternatively, use pthreads-win32 I suppose…

  • How to use pom.xml/Maven to initialize a local thoughtsite (App Engine sample) project in Eclipse?

    - by ovr
    This sample app ("thoughtsite") for App Engine contains a pom.xml in its trunk: http://code.google.com/p/thoughtsite/source/browse/#svn/trunk But I don't know what command to run in Maven to set up the project locally. (The README doesn't mention anything about Maven.) I tried to just import the project code directly into Eclipse but it doesn't look like it's in an appropriate format for a direct import. So I assume I need to do something with Maven to get it set up correctly. I haven't really used Maven before so I'm not sure what command I would need to run to set everything up. The pom.xml seems like it downloads a bunch of dependencies for the project like the Spring jar files which I don't see anywhere else in the svn repository.

  • CentOS: revert python version back to original

    - by NP
    Hi all, I installed python 2.6 using the instructions here on CentOS 5.4. However I realized it was a bad move and I need to revert back to 2.4, which was there originally. Can anyone guide me on how to undo what I did here? In particular, I am not sure how to undo this: Configure ld to find your shared libs: $ cat /etc/ld.so.conf.d/opt-python2.5.conf /opt/python2.5/lib (hit enter) (hit ctrl-d to return to shell) $ ldconfig I tried removing the alias and the symlink and even re-aliasing python to /usr/bin/python, but when I try to install an RPM i get this error: error: Failed dependencies: libpython2.4.so.1.0 is needed by ... Thanks in advance.

  • How can I get JavaDoc into a JunitReport?

    - by benklaasen
    Hi - I'm a tester, with some Java and plenty of bash coding experience. My team is building an automated functional test harness using JUnit 4 and ant. Testers write automated tests in Java and use JavaDoc to document these tests. We're using ant's JunitReport task to generate our test result reports. This works superbly for reporting. What we're missing, however, is a way to combine those JavaDoc free-text descriptions of what the test does along with the JunitReport results. My question is, what's involved to get the JavaDoc into the JunitReport output? I'd like to be able to inject the JavaDoc for a given test method into the JunitReport at the level of each method result. regards Ben

  • Invoke Maven-Module build from intellij

    - by Roman
    Hi All I was wondering if someone knows a way to invoke a specific maven module build from IntelliJ that will also build ( or use already compiled classes ) from depended modules. So for instance if I would like to build the module "Model" in the picture and only it , it seems reasonable for me to click the package step on it. But what is actually does it invokes the mvn package step inside this specific module rather than "mvn -am -pl module-name" from the root module , which also builds all the dependencies. So is there something that I just don't know ?

  • Is there a cross-platform CD/DVD burning library or command-line app?

    - by Computer Linguist
    I'm looking for a cross-platform CD & DVD burning library. I'm not too particular about the language or framework a long as there are minimal dependencies and they are easily installable cross-platform, or already exist. A command-line application would also work.. Looking to target WinXP, Vista, Win7, OS X Leopard & Snow Leopard, & most linux distros. I know I can write an .iso cross platform, but I'm looking for a way to burn those .ISOs to disk on a variety of platforms without having to code seperately for each one. It's for burning MP3 disks and standard audio CDs... All suggestions appreciated.

  • iPhone app rejected because of Beta word is used

    - by arielcamus
    Hi, I was using the text "We are currently on Beta. Please, enter our website and ask for an invitation" when a user click on "Register" on our app. However, Apple has rejected our app because it can not has any disabled featured and can not contains word "Beta". What would you do in this situation? I don't know if hide this option and show it only when an API call response says "registerEnabled = YES" or just change the text and use: "You need and invitation to access OUR_APP. Visit our website to get one." Except for registering, our app is fully functional. Thank you, A

  • Ruby get inheriting class

    - by Brian D.
    I'm working on creating my first plugin for rails. I'm still pretty new to ruby and I was wondering if its possible to get the inheriting class? For example, I'm trying to create a plugin that will allow unit testing and functional testing when you are not using migrations. What I'm trying to do is initialize a class variable named controller to be initialized to the type of controller that is being tested. If I have a base class ControllerTest: class ControllerTest < Test::Unit::TestCase attr_accessor :controller def initialize super @controller = "call function that will find the inheriting classes name and create an instance of that controller type." end end So what I'm currently stuck on is getting the name of the inheriting class. Is this possible? And if not, does anyone know another way on how I could go about implementing this? Thanks in advance.

  • Why do Java/C# edge out C++ as the recommended language to learn OOP on S.O?

    - by viksit
    I noticed after reading the answers/discussion to this question (What is the best language to learn OOP on?) - that more and more people are recommending C# or Java over C++ to learn OOP on. A simple term search on that answer page results in 10 hits for C++, 21 for C# and 27 for Java. Now, I understand that these 2 languages fix a lot of quirks and issues with C++, and looked up these resources that relate mostly to performance, JVM vs native implementation, systems focus vs applications, manual memory management vs automated et al. My question is - are there any fundamental differences in the OO capabilities of Java/C# vs C++? Or are the former recommended purely due to their generic ease of use/improvements over the latter? Thanks. PS, I'm aware of Java interface inheritance vs C++ multiple inheritance as a difference. I would consider that an implementational one rather than functional.

  • Porting WebSphere code to get remote credentials to Tomcat

    - by Glenn Lawrence
    I have been asked to look into porting some code from a web app under IBM WAS 7 so that it will run under Tomcat 7. This is part of a larger SPNEGO/Kerberos SSO system but for purposes of discussion I have distilled the code down to the following that shows the dependencies on the two WebSphere classes AccessController and WSSubject: GSSCredential clientCreds = (GSSCredential) com.ibm.ws.security.util.AccessController.doPrivileged(new java.security.PrivilegedAction() { public Object run() { javax.security.auth.Subject subject = com.ibm.websphere.security.auth.WSSubject.getCallerSubject(); GSSCredential clientCreds = (GSSCredential) subject.getPrivateCredentials(GSSCredential.class).iterator().next(); return clientCreds; } }); I'd like to be able to do this in Tomcat.

  • Simulating Ajax failures for QA testing

    - by womp
    Our first ASP.Net MVC/jQuery product is about to go to QA, and we're looking for a way for our QA guys to easily be able to simulate bad Ajax requests (without modifying the application code). A typical integration/UI test plan might be: Load page, click button "DoStuff" "DoStuff" fails Attempt button "DoStuff" again "DoStuff" succeeds Verify application state This is a simple test case - there will be cases with multiple failures and successes interspersed. Aside from "unplug your network cable" I'm looking for an easy way for our guys to simulate intermittent bad server responses. I'm open to any ideas so I won't go into too many details about our application setup or dependencies. How have you handled this?

  • What is the difference between a constructor and a procedure in Delphi records?

    - by HMcG
    Is there difference in behavior between a constructor call and a procedure call in Delphi records? I have a D2010 code sample I want to convert to D2009 (which I am using). The sample uses a parameterless constructor, which is not permitted in Delphi 2009. If I substitute a simple parameterless procedure call, is there any functional difference for records? I.E. TVector = record private FImpl: IVector; public constructor Create; // not allowed in D2009 end; becomes TVector = record private FImpl: IVector; public procedure Create; // so change to procedure end; As far as I can see this should work, but I may be missing something.

  • Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

    - by Relequestual
    I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

  • Massive speed diff in upgrade to Java 7

    - by Brett Rigby
    We use Java within our build process, as it is used to resolve/publish our dependencies via Ivy. No problem, nor have we had with it for 2 years, until we've tried to upgrade Java 6 Update 26 to Version 7 Update 7, whereas a build on a local developer PC (WinXP) now takes 2 hours to complete, instead of 10 minutes!! Nothing else has changed on the PC, making it the absolute target for our concerns. Does anyone know of any reason as to why version 7 of Java would make such a speed difference like this?

  • GQL: I'm storing JSON in the DataStore. All json is getting converted to html entities, how to avoid

    - by fmsf
    The tittle says most: I'm storing JSON in the DataStore. All json is getting converted to html entities, how can I avoid this? Original I had myJson = db.StringProperty() it complained the json i had was to long and StringProperty had a limit of around 500 chars. Sugesting to use TextProperty instead. It inserted without problems but now myJson looks like this when i fetch it from the database: { &quot;timeUnit&quot;: &quot;14&quot;, &quot;taskCounter&quot;: &quot;0&quot;, &quot;dependencyCounter&quot;: &quot;0&quot;, &quot;tasks&quot;: [], &quot;dependencies&quot;: []} Any sugestions?

  • Cucumber works on Eclipse but not on Jenkins

    I am successfully running Cucumber test on my java/maven eclipse project. But when I add my project do Jenkins I always get the following error "cucumber.runtime.CucumberException: No features found at []". I read in this thread Setting cucumber-jvm options in Maven from the command line that: ...tests are running in separate JVM, so you need to specify that system property in the test plugin configuration (i.e. surefire or failsafe plugin config in your pom.xml) But I am not quite sure how to do this. Can anyone help me? PS: I am using "cucumber-java" and "cucumber-junit" dependencies.

  • Use WM_COPYDATA to send data between processes

    - by Charles Gargent
    I wish to send text between processes. I have found lots of examples of this but none that I can get working. Here is what I have so far: for the sending part: COPYDATASTRUCT CDS; CDS.dwData = 1; CDS.cbData = 8; CDS.lpData = NULL; SendMessage(hwnd, WM_COPYDATA , (WPARAM)hwnd, (LPARAM) (LPVOID) &CDS); the receiving part: case WM_COPYDATA: COPYDATASTRUCT* cds = (COPYDATASTRUCT*) lParam; I dont know how to construct the COPYDATASTRUCT, I have just put something in that seems to work. When debugging the WM_COPYDATA case is executed, but again I dont know what to do with the COPYDATASTRUCT. I would like to send text between the two processes. As you can probably tell I am just starting out, I am using GNU GCC Compiler in Code::Blocks, I am trying to avoid MFC and dependencies.

  • PHP won't parse MySQL statements

    - by Hussain
    I just installed Apache 2.2.15/PHP 5.3.2/MySQL 5.1.44 on Windows Vista. Apache is working fine, PHP is functional, and MySQL works on the CLI. However, when I try to access MySQL via PHP, I get an error (Fatal error: Call to undefined function mysql_connect()). extension=php_mysql.dll and extension=php_mbstring.dll are uncommented in the php.ini file, and PHP is in the system path. There is no libmysql.dll in either the top level PHP directory or the ext directory. There's a libmySQL.dll file in the MySQL bin directory (which is also in the system path); I tried renaming it, but that doesn't do anything Also, in case anyone wants to know, I originally installed PHP using the MSI installer, but it was missing some DLLs, so I installed from the zip file. I think I've exhausted all my options. Any help on this problem would be very appreciated. Thanks in advance.
