  • How to link C# and C++ assemblies into a single executable

    - by swingkid
    I have VS2008 solution containg a project that generates a C# executable that references a project that generates a dll containing both C++/CLI and unmanaged C++. I would like to merge these into a single executable, as the C++ dll contains security code that I want to embed in the main executable. I cannot use ILMerge, as the dll contains both managed and unmanaged code. The suggested solution seems to be to use link.exe to link the C# assembly with the C++ object files. This is what I am trying to do. I manually edited the project file for the c# executable to generate a netmodule. I added a post build step to the executable project to run link.exe to link the c# netmodule and the compiled C++ object files together, then run mt.exe to merge the assembly manifests created by both projects. This runs successfully, but the exe still contains a reference to and uses the c++ types defined in the dll generated by the normal build process for the C++ project. I then specified /NOASSEMBLY in the project settings for the C++ dll, so it also generates a netmodule. In the C# project, I removed the reference to the C++ project, but added a project dependancy in the solution. I manually edited the C# project file to include similar to: <ItemGroup> <AddModules Include="..\Debug\librarycode.netmodule" /> </ItemGroup> i.e. to reference the C++ netmodule that is now generated by the C++ project. However, now the linker step in my post build event fails with: error LNK2027: unresolved module reference 'librarycode.netmodule' fatal error LNK1311: 1 unresolved module references: This is entirely understandable, as I am not linking in the librarycode netmodule; I am linking in the C++ object files used to generate the netmodule instead. So in short, how do I merge a c# executable and C++ object files into a single assembly? What have I missed? My source of reference so far (appart from the link.exe command link reference etc on MSDN) are the two following articles: http://blogs.msdn.com/texblog/archive/2007/04/05/linking-native-c-into-c-applications.aspx http://www.hanselman.com/blog/MixingLanguagesInASingleAssemblyInVisualStudioSeamlesslyWithILMergeAndMSBuild.aspx I have a demonstration solution that shows my workings so far, if this helps. Thank you very much in advance.

  • What’s the strategy to recover data during DAO unit test?

    - by Michael Lu
    When I test DAO module in JUnit, an obvious problem is: how to recover testing data in database? For instance, a record should be deleted in both test methods testA() and testB(), that means precondition of both test methods need an existing record to be deleted. Then my strategy is inserting the record in setUp() method to recover data. What’s your better solution? Or your practical idea in such case? Thanks

  • South migration error: NoMigrations exception for django.contrib.auth

    - by danpalmer
    I have been using South on my project for a while, but I recently did a huge amount of development and changed development machine and I think something messed up in the process. The project works fine, but I can't apply migrations. Whenever I try to apply a migration I get the following traceback: danpalmer:pest Dan$ python manage.py migrate frontend Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) File "/Library/Python/2.6/site-packages/django/core/management/__init__.py", line 362, in execute_manager utility.execute() File "/Library/Python/2.6/site-packages/django/core/management/__init__.py", line 303, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 195, in run_from_argv self.execute(*args, **options.__dict__) File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 222, in execute output = self.handle(*args, **options) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/management/commands/migrate.py", line 102, in handle delete_ghosts = delete_ghosts, File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/migration/__init__.py", line 182, in migrate_app applied = check_migration_histories(applied, delete_ghosts) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/migration/__init__.py", line 85, in check_migration_histories m = h.get_migration() File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/models.py", line 34, in get_migration return self.get_migrations().migration(self.migration) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/models.py", line 31, in get_migrations return Migrations(self.app_name) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/migration/base.py", line 60, in __call__ self.instances[app_label] = super(MigrationsMetaclass, self).__call__(app_label_to_app_module(app_label), **kwds) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/migration/base.py", line 88, in __init__ self.set_application(application, force_creation, verbose_creation) File "/Library/Python/2.6/site-packages/South-0.7-py2.6.egg/south/migration/base.py", line 159, in set_application raise exceptions.NoMigrations(application) south.exceptions.NoMigrations: Application '<module 'django.contrib.auth' from '/Library/Python/2.6/site-packages/django/contrib/auth/__init__.pyc'>' has no migrations.

I ran 'easy_install -U South' just to make sure. Thanks for any help that you can provide. I really appreciate it.

  • C program debugging in gdb problem

  • gcc precompiled headers weird behaviour with -c option

    - by pachanga
    Folks, I'm using gcc-4.4.1 on Linux and before trying precompiled headers in a really large project I decided to test them on simple program. They "kinda work" but I'm not happy with results and I'm sure there is something wrong about my setup. First of all, I wrote a simple program(main.cpp) to test if they work at all: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> int main() { return 0; } Then I created the precompiled headers file pre.h(in the same directory) as follows: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> ...and compiled it: $ g++ -I. pre.h (pre.h.gch was created) After that I measured compile time with and without precompiled headers: with pch $ time g++ -I. -include pre.h main.cpp real 0m0.128s user 0m0.088s sys 0m0.048s without pch $ time g++ -I. main.cpp real 0m0.838s user 0m0.784s sys 0m0.056s So far so good! Almost 7 times faster, that's impressive! Now let's try something more realistic. All my sources are built with -c option and for some reason I can't make pch play nicely with it. You can reproduce this with the following steps below... I created the test module foo.cpp as follows: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> int whatever() { return 0; } Here are the timings of my attempts to build the module foo.cpp with and without pch: with pch $ time g++ -I. -include pre.h -c foo.cpp real 0m0.357s user 0m0.348s sys 0m0.012s without pch $ time g++ -I. -c foo.cpp real 0m0.330s user 0m0.292s sys 0m0.044s That's quite strange, looks like there is no speed up at all!(I ran timings for several times). It turned out precompiled headers were not used at all in this case, I checked it with -H option(output of "g++ -I. -include pre.h -c foo.cpp -H" didn't list pre.h.gch at all). What am I doing wrong?

  • What are codepad.org's Perl runner limitations?

    - by Lemurik
    Sometimes I see people use http://codepad.org as a way to quickly run/test their Perl snippets (it supports doing that with a wide variety of languages, from C to Scheme to Perl). It's pretty obvious that there must be some limitations as to what code/features can be tested with codepad - does anyone know what those limitations are for Perl runner? I'll get the ball rolling on my own observation: not every CPAN module is available :(

  • Prevent checkins to SVN

    - by Joseph Mastey
    My team uses SVN for our software platform, and we create tags periodically to help keep module versions straight. Best practice, as I understand it, is not to modify a tag once it has been created. However, it seems that sometimes the temptation is too great and a modification is made to one of the tags. Is there a way to prevent these kinds of checkins, or at least make them a complete pain so that we can discourage them automatically? Thanks, Joe

  • Graph layouting with Perl

    - by jonny
    Ok, I have a flowchart definition (basically, array of nodes and edges for each node). Now I want to calculate coordinates for every task in the flow, preferably hierarchycal style. I need something like Graph::Easy::Layout but I have no idea how to get nodes coordinates: I render nodes myself and I only want to retrieve box coordinates/size. Any suggestions? What I need is a cpan module avialable even in Debian repository.

  • MySQL -- enable connection to remote server via local /tmp/mysql.sock

    - by Kevin
    Hey all, I run a shared hosting provider and we're looking to move to a High Availability (replicated across multiple datacenters) setup for our hosting. We have created a replicated MySQL setup with failover that works wonderfully, and we'd like to move all of our clients' databases to it. The only trouble is that we have many many customers, all of whom have configured their Wordpress, Drupal, etc. installations to connect to MySQL via a local socket, not to the address of the remove server. I would hate to have to go through manually and change the connection statement in all of our clients' sites. What I'd ideally love to see is a program that listens on /tmp/mysql.sock and forwards connections there to the remote server I specify. I've seen SQL Relay, but it seems to require that I hardcode all of the database names and usernames and passwords into its configuration file. This is not going to work for me because our users add new databases dynamically all of the time, and I'd rather not have to write code to updated SQLRelay's config file every time. Does anyone have an idea on how to do this? Alternatively, I'd accept idea on how to handle this at the PHP level. (i.e. redirect any attempted calls to mysql_connect() to use that hostname rather than localhost) Thanks, Kevin

  • Detect marker with opencv and python

    - by Mitch
    Hi im trying to detect a marker in a webcam video feed and overlay it with a 3d object - pretty much exactly like this: http://www.morethantechnical.com/2009/06/28/augmented-reality-with-nyartoolkit-opencv-opengl/ i know artoolkit is the best module for this, but i was hoping to just use opencv in python since i dont know nearly enough c/c++ to be able to use artoolkit. im hoping someone will be able to get me on the right track towards detecting the marker and determining its location and orientation etc since i have no idea how best to go about this or what functions i should be using thanks mitch

  • How do I determine the cause of a sustained spike in mysql queries/activity?

    - by mattmcmanus
    So this is more of a "I'm trying to learn about how this works" question rather than "there is a serious problem I can't figure out!" question. I'm setting up a VPS and have been tweaking and changing things here and there. I recently installed munin (like two days ago) and yesterday I noticed a significant increase in mysql activity. So now my curiosity is going crazy. How do I setup/access mysql's query log? I have about 5 databases on the server so I want to see which one is getting all the action. Is there anything else I can do to keep a better eye on what's going on? Here are the graphs. As you can tell, it's not that much activity at all but I'm just curious at the change. The sites that are on the server right now do not get a lot of traffic. It's running a couple drupal sites, only one of which is live. The live one hasn't had a spike in traffic and the last spike was 250 visitors so it's barely a spike at all.

  • How to deploy a rar file to jboss

    - by Joshua
    Refer original post here for a reference to the original issue. What plugin should I use to deploy the jackrabbit rar as a separate entity to the jboss installation. I tried the rar module within the maven-ear-plugin which was actually packaging this within the ear file and the rar plugin which seems to be used for packaging a rar. Currently I am using the antrun plugin to deploy the rar file and it's associated ds.xml, is there a different plugin to automate direct deployment.

  • imagick showing script url instead of image

    Hi, currently i'm trying to use imagick to generate some images without saving them on the server and then outputting to the browser, my method of choice was image magic with the imagick extension for php.
