• C/C++ usage of special CPU features

  - by b-gen-jack-o-neill

  Hi, I am curious, do new compilers use some extra features built into new CPUs such as MMX SSE,3DNow! and so? I mean, in original 8086 there was even no FPU, so compiler that old cannot even use it, but new compilers can, since FPU is part of every new CPU. So, does new compilers use new features of CPU? Or, it should be more right to ask, does new C/C++ standart library functions use new features? Thanks for answer.

• Java source code generation frameworks

  - by Superfilin

  I have a set of Java 5 source files with old-style Doclet tags, comments and annotations. And based on that I would like to write a generator for another set of Java classes. What is the best way to do that? And are there any good standalone libraries for code analysis/generation in Java? Any shared exprience in this field is appreciated. So, far I have found these: JaxME's Java Source Reflection - seems good, but it does not seem to support annotations. Also it had no release since 2006. Annogen - uses JDK's Doclet generator, which has some bugs under 1.5 JDK. Also it had no releases for a long time. Javaparser - seems good as well and pretty recent, but only supports Visitor pattern for a single class i.e. no query mechanism like in the 2 above packages.

• How to convert full outer join query to O-R query?

  - by Kugel

  I'm converting relational database into object-relational in Oracle. I have a query that uses full outer join in the old one. Is it possible to write the same query for O-R database without explicitly using full outer join? For normal inner join it simple, I just use dot notation together with ref/deref. I'm interested in this in general so let's say the relational query is: select a.attr, b.attr from a full outer join b on (a.fk = b.pk); I want to know if it's a good idea to do it this way: select a.attr, b.attr from a_obj a full outer join b_obj b on (a.b_ref = ref(b));

• Releasing WinForm Program Updates

  - by Tinkerer_CardTracker

  Hello, Another quick question. I'd like to release some updates for a WinForm program, but to date I have simply released an all-new compile. People have to un-install the old version and install the new version. I bet there's a way to get around this, but I don't know what it's called. As you may guess, searches for "updates" "new version" "install" and the other obvious things I've tried have generated an impressive number of irrelevant results. _< I suspect this process has a particular name, which should point me in the right direction, but if it doesn't please link to a tutorial or something. Thanks again, this site is great! :)

• VS 2010 Entity Repository Error Class member EntityBase.id is unmapped.

  - by Steve

  In my project I have it set up so that all the tables in the DB has the property "id" and then I have the entity objects inherit from the EntityBase class using a repository pattern. I then set the inheritance modifier for "id" property in the dbml file o/r designer to "overrides" Public MustInherit Class EntityBase MustOverride Property id() As Integer End Class Public MustInherit Class RepositoryBase(Of T As EntityBase) Protected _Db As New DataClasses1DataContext Public Function GetById(ByVal Id As Integer) As T Return (From a In _Db.GetTable(Of T)() Where a.id = Id).SingleOrDefault End Function End Class Partial Public Class Entity1 Inherits EntityBase End Class Public Class TestRepository Inherits RepositoryBase(Of Entity1) End Class the line Return (From a In _Db.GetTable(Of T)() Where a.id = Id).SingleOrDefault however produces the error "Class member EntityBase.id is unmapped" when i use VS 2010 using the 4.0 framework but I never received that error with the old one. Any help would be greatly appreciated. Thanks in advance.

• Building Boost with LSB C++ Compiler

  - by Alex Farber

  I want to build my program with LSB C++ Compiler from the Linux Standard Base http://www.linuxfoundation.org/collaborate/workgroups/lsb. Program depends on the Boost library, built with gcc 4.4 version. Compilation fails. Is it possible to build the Boost library with LSB C++ Compiler? Alternatively, is it possible to build the Boost library with some old gcc version, what version is recommended? My final goal is to get my executable and third-party Boost libraries running on most Linux distributions. Generally, what can be done to get better binary compatibility for Linux distributions, developing C++ closed-source application depending on the Boost library?

• is XULRUNNER suitable as a replacement for other C++ desktop applications frameworks such as QT?

  - by Gabriel Cuvillier

  XulRunner/Gecko seems to be really interesting for developing gui-intensive applications (by using widely used technologies such as HTML / CSS / SVG / XUL / Javascript). But the underlaying C++ APIS (XPCOM, NECKO, ...) looks so old and complex. Moreover the general lack of documentation/developper tools is really frightening. On the other hand, QT have a quite nice platform, and is well documented and supported. The UI part is really "traditional" though. What are your experiences with XULRUNNER, specially compared to other C++ desktop applications frameworks such as QT/GTK/MFC...? What is missing? What is awesome? Side question: If I wanted to migrate an existing MFC app to a cross platform C++ desktop application framework, would it be wise to use XULRUNNER instead of QT or GTK?

• Most Efficient way to set Register to 1 or (-1)

  - by Bob

  I am taking an assembly course now, and the guy who checks our home assignments is a very pedantic old-school optimization freak. For example he deducts 10% if he sees: mov ax, 0 instead of: xor ax,ax even if it's only used once. I am not a complete beginner in assembly programing but I'm not an optimization expert, so I need your help in something (might be a very stupid question but I'll ask anyway): if I need to set a register value to 1 or (-1) is it better to use: mov ax, 1 or do something like: xor ax,ax inc ax I really need a good grade, so I'm trying to get it as optimized as possible. ( I need to optimize both time and code size)

• Using windows CopyFile function to copy all files with certain name format

  - by Ben313

  Hello! I am updating some C code that copys files with a certain name. basically, I have a directory with a bunch of files named like so: AAAAA.1.XYZ AAAAA.2.ZYX AAAAA.3.YZX BBBBB.1.XYZ BBBBB.2.ZYX Now, In the old code, they just used a call to ShellExecute and used xcopy.exe. to get all the files starting with AAAAA, they just gave xcopy the name of the file as AAAAA.* and it knew to copy all of the files starting with AAAAA. now, im trying to get it to copy with out having to use the command line, and I am running into trouble. I was hoping CopyFile would be smart enough to handle AAAAA.* as the file to be copied, but it doesnt at all do what xcopy did. So, any Ideas on how to do this without the external call to xcopy.exe?

• How do I temporarily change the require path in Ruby ($:)?

  - by John Feminella

  I'm doing some trickery with a bunch of Rake tasks for a complex project, gradually refactoring away some of the complexity in chunks at a time. This has exposed the bizarre web of dependencies left behind by the previous project maintainer. What I'd like to be able to do is to add a specific path in the project to require's list of paths to be searched, aka $:. However, I only want that path to be searched in the context of one particular method. Right now I'm doing something like this: def foo() # Look up old paths, add new special path. paths = $: $: << special_path # Do work ... bar() baz() quux() # Reset. $:.clear $: << paths end def bar() require '...' # If called from within foo(), will also search special_path. ... end This is clearly a monstrous hack. Is there a better way?

• C++ Constructor Initializer List - using member functions of initialized members

  - by Andy

  I've run into the following a few times with initializer lists and I've never been able to explain it well. Can anyone explain why exactly the following fails (I don't have a compiler to catch typos, so bear with me): class Foo { public: Foo( int i ) : m_i( i ) {} //works with no problem int getInt() {return m_i;} ~Foo {} private: int m_i; }; class Bar { public: Bar() : m_foo( 5 ), //this is ok m_myInt( m_foo.getInt() ) //runtime error, seg 11 {} ~Bar() {} private: Foo m_foo; int m_myInt; }; When trying to call member functions of members initialized higher up the initializer list, I get seg faults. I seem to recall this is a known problem (or perhaps somehow by design) but I've never seen it well described. The attached example is contrived with plain old data types, but substitute the Bar::m_myInt with another object lacking a default (empty) constructor and the issue is more real. Can anyone enlighten me? Thanks!

• Windows environment variables change when opening command line?

  - by Jakobud

  Sometimes when I change my environment variables in Windows, and then use software the depends on those variables, they are not properly updated. And good example is to change a variable, then open up Windows Command Line and echo the variable and see that it hasn't been changed, even though you properly changed it in the Environment Variables window. Another example I'm dealing with right now: I've been using Python 2.4.x for a while for a project, which uses the env var PYTHONPATH who's value has been: C:\Python24;C:\Python24\lib Today I installed Python 2.5.x for the project. I changed my PYTHONPATH to be: C:\Python25;C:\Python25\lib When I use Python 2.5 to run a script and do this: import sys print sys.path It prints: 'C:\\PYTHON24', 'C:\\PYTHON24\\lib' (and some other Python 2.5 related default installation paths) So clearly, the old PYTHONPATH environment variable changes aren't really sticking.... Does anyone know why this happens and how to fix it?

• creating a wordpress dev enviornment and uploading to production

  - by Jeff

  I am an old school java developer who is considering a using wordpress. I'm used to developing locally on my PC (yeah yeah not even a mac) and then ftping my files up to a production environment on a remote server. My high level review of wordpress gives me the impression that typically there is no concept of lower environments and that all updates occur directly in production. Is this the case? If not, can someone explain how one goes about uploading the files to a web site? Thanks, Jeff

• Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

  - by nganju

  I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

• OpenGL ES 2.0 Rendering with a Texture

  - by Kyle

  The iPhone SDK has an example of using ES 2.0 with a set of (Vertex & Fragment) GLSL shaders to render a varying colored box. Is there an example out there on how to render a simple texture using this API? I basically want to take a quad, and draw a texture onto it. The old ES 1.1 API's don't work at all anymore, so I'm needing a bit of help getting started. Most shader references talk mainly about advanced shading topics, but I'm really unsure about how to tell the shader to use the bound texture, and how to reference the UV's. Thanks!

• git: rename remote branch

  - by Albert

  I have the branch master which tracks the remote branch origin/master. I want to rename them to "master-old" both locally and remote. Is that possible? For other users who tracked origin/master (and who updated their local master branch always just via 'git pull'), what whould happen after I renamed the renamed the remote branch. Would their 'git pull' still work or would it throw an error that it coudln't find origin/master anymore? Then, further on, I want to create a new master branch (both locally and remote). Again, after I did this, what would happen now if the other users do the 'git pull' now? I guess all this would result in a lot of trouble. Is there a clean way to get what I want? Or should I just leave master as it is and create a new branch master-new and just work there further on?

• What should I do that GWT use <th> instead of <td>?

  - by Paulus

  To build a HTML table I use direct DOM instead of a predefined Widget to set thead and tbody. But when I insert a cell with the insertCell() method GWT inserts an td element but should insert an th element. So TableElement table = Document.get().createTableElement(); TableSectionElement thead = table.createTHead(); TableRowElement headRow = thead.insertRow(-1); headRow.insertCell(-1).setInnerText( "header1" ); gives table/thead/tr/td but should give table/thead/tr/th Any idea how to solve this problem? Use the "old-school" DOM.createXXX()-Methods?

• Book resources for x86/x64 assembly programming on Win platform

  - by Scott Davies

  Hello, I ran a search for assembly language resources on stackoverflow.com and found some interesting results, but they seemed to boil down to two groups: 1) Assembly references to old ia32 architecture, such as the 80386 to Pentium 2) Windows agnostic books. Most of the commenters make the point that assembler is CPU dependent and that the OS is irrelevant, but it seems pointless to me to pick a book that has assembly examples that refer to MS-DOS interrupts and memory layouts. Likewise, learning assembler on Linux would seem to produce Linux executables Are there any: 1) Modern 2) x86/x64 3) on Windows platform - book resources available ? The reason I am targeting the Win platform is I would like to do low-level, OS internals programming, to supplement my Win C/C++ work. Thanks

• JavaScript helper libraries? No DOM or AJAX stuff

  - by Melmacian

  As I'm writing JavaScript I'm always missing some fairly basic language features that JavaScript just don't have. So is there any library that would bring such features as trim, sprintf, str.endwith and etc. functions to JavaScript ? I just have written those functions too many times and I'm also tired of copy/pasting them from my old code. It would be nice to have some library which has those implemented and tested in one place. Note that I'm not talking about Ajax/DOM-libraries like jQuery or Dojo and such. I know that those libraries bring some of the features that I'm talking here, but not all. And I would like to have also an environment independent library so that same library could be used with server side JavaScript . Best library so far that I've found is php.js, but I don't like how it is polluting the global namespace. I'm also not too fond of how PHP-functions are named.

• Template class implicit copy constructor issues

  - by Nate

  Stepping through my program in gdb, line 108 returns right back to the calling function, and doesn't call the copy constructor in class A, like (I thought) it should: template <class S> class A{ //etc... A( const A & old ){ //do stuff... } //etc... }; template <class T> class B{ //etc... A<T> ReturnsAnA(){ A<T> result; // do some stuff with result return result; //line 108 } //etc... }; Any hints? I've banged my head against the wall about this for 4 hours now, and can't seem to come up with what's happening here.

• Why should I use mock objects (Java)? Do all mocking frameworks serve the same purpose?

  - by Mehmet Yesin

  I'm preparing a presentation and I need to get a better understanding of what mocking is, what is the purpose of using it, what are the common situations that I should use mock objects? I found out that there are a bunch of mocking frameworks out there. Do they all do the same thing or do I use a specific framework for specific testing purpose? What are the differences between these frameworks? Which one would you recommend for testing Java? here are some stuff that I found: 1.MockingToolkitComparisonMatrix which seems biased. 2.What are mock objects in Java? This is a year old. I thought there might be some better answer today. Thank you.

• Best direction for displaying game graphics in C# App

  - by Mike Webb

  I am making a small game as sort of a test project, nothing major. I just started and am working on the graphics piece, but I'm not sure the best way to draw the graphics to the screen. It is going to be sort of like the old Zelda, so pretty simple using bitmaps and such. I started thinking that I could just paint to a Picture Box control using Drawing.Graphics with the Handle from the control, but this seems cumbersome. I'm also not sure if I can use double buffering with this method either. I looked at XNA, but for now I wanted to use a simple method to display everything. So, my question. Using the current C# windows controls and framework, what is the best approach to displaying game graphics (i.e. Picture Box, build a custom control, etc.)
