  • What is a good program for storing “chunks” of commonly used source code

    - by Rob Wiley
    I've looked at CodeLocker (poorly styled and relatively unflexible, but free) and Source Code Library (Overzone software - very nicely styled, looks flexible, but very expensive - $80). Ideally, I'm looking for a relatively simple, inexpensive program (not an online website) that I can save text data (source code) with a title and keywords, maybe even a description. It would also have some type of search functionality.

  • Java Compare Addresses

    - by Tom
    Hi, Does anyone know a library to compare addresses in Java ? Something that would give equality on addresses, written in different ways. For example, it should recognize that "22 Acacia Avenue" and "22 acacia av." is the same address. Of course, this can escalate a lot, that's why i'm asking. Thanks in advance.

  • Generation of abstract class with JCodeModel

    - by SadJokerBY
    I'm trying to generate top-level abstract class with JCodeModel library, but I can't find any way to change class modifiers. It's possible for nested classes (JDefinedClass API provides methods that get modifiers as parameters). But for creation of top level classes I found only JCodeModel API methods that get fully qualified name with or without ClassType (class/interface/annotation/enum) as parameters. Does anybody can suggest me how to change modifiers of JDefinedClass to make it abstract?

  • C++ Reference Book

    - by m00st
    Can someone list a C++ book that is just a reference to the standard library? I don't need a "learning c++" book just one that is a reference. Or at least official documentation or something? Googling only reveals "fan-site" reference.

  • What browser incompatibilities does jquery solve?

    - by pd1138
    I'm currently on the fence about using or not using jquery. I've spent hours researching the pros and cons of using jquery (or any library for that matter). One of the big selling points of jquery is that it frees a developer from worrying about browser incompatibilities. I've tried to find any documentation on exactly which incompatibilities it overcomes. So far I haven't found any. Can anyone help me out with this.

  • Generic DRM (Distributed resource management) wrapper

    - by Pavel Bernshtam
    I need to write a software, which launches DRM jobs in a customer environment and monitors those jobs status. It should work with various customer environments and DRMs - like LSF, Sun Grid and others. Can you recommend some 3rd party library, which hides DRM differences from me and has API like "launch job", "get list of jobs", "get job status" etc. ? Both Java and native libraries are good for me.

  • SPNavigationNode.IsVisible property not working as expected.

    - by Manish
    My code is as under: using (SPSite spSiteTest = new SPSite(serverUrl)) { using (SPWeb mySite = spSiteTest.OpenWeb()) { SPNavigationNodeCollection quickLaunchNodes = mySite.Navigation.QuickLaunch; SPNavigationNode navQuickNode = new SPNavigationNode("Title", "www.stackoverflow.com", true); foreach (SPNavigationNode node in quickLaunchNodes) { if (node.Title == navQuickNode.Title) { node.Url = navQuickNode.Url; node.IsVisible = isVisible; node.Update(); //mySite.Update(); return; } } quickLaunchNodes.AddAsFirst(navQuickNode); } } I want to hide a quick launch node but using the above code, it's not working. :( Am I missing something?

  • Using mem_fun_ref with boost::shared_ptr

    - by BlueRaja
    Following the advice of this page, I'm trying to get shared_ptr to call IUnknown::Release() instead of delete: IDirectDrawSurface* dds; ... //Allocate dds return shared_ptr<IDirectDrawSurface>(dds, mem_fun_ref(&IUnknown::Release)); error C2784: 'std::const_mem_fun1_ref_t<_Result,_Ty,_Arg std::mem_fun_ref(Result (_thiscall _Ty::* )(_Arg) const)' : could not deduce template argument for 'Result (_thiscall _Ty::* )(Arg) const' from 'ULONG (_cdecl IUnknown::* )(void)' error C2784: 'std::const_mem_fun_ref_t<_Result,_Ty std::mem_fun_ref(Result (_thiscall _Ty::* )(void) const)' : could not deduce template argument for 'Result (_thiscall _Ty::* )(void) const' from 'ULONG (__cdecl IUnknown::* )(void)' error C2784: 'std::mem_fun1_ref_t<_Result,_Ty,_Arg std::mem_fun_ref(Result (_thiscall _Ty::* )(_Arg))' : could not deduce template argument for 'Result (_thiscall _Ty::* )(Arg)' from 'ULONG (_cdecl IUnknown::* )(void)' error C2784: 'std::mem_fun_ref_t<_Result,_Ty std::mem_fun_ref(Result (_thiscall _Ty::* )(void))' : could not deduce template argument for 'Result (_thiscall _Ty::* )(void)' from 'ULONG (__cdecl IUnknown::* )(void)' error C2661: 'boost::shared_ptr::shared_ptr' : no overloaded function takes 2 arguments I have no idea what to make of this. My limited template/functor knowledge led me to try typedef ULONG (IUnknown::*releaseSignature)(void); shared_ptr<IDirectDrawSurface>(dds, mem_fun_ref(static_cast<releaseSignature>(&IUnknown::Release))); But to no avail. Any ideas?

  • ELF: linking: Why do I get undefined references in .so files

    - by ki.lya.online.fr
    Hi, I'm trying to build a program against wxWidgets, and I get a linker error. I'd like to really understand what it means. The error is: /usr/lib/libwx_baseu-2.8.so: undefined reference to `std::ctype<char>::_M_widen_init() const@GLIBCXX_3.4.11' What I don't understand is why the error is at libwx_baseu-2.8.so. I thought that .so files had all its symbols resolved, contrary to .o files that still need linking. When I ldd the .so, I get can resolve all its linked libraries, so there is no problem there: $ ldd /usr/lib/libwx_baseu-2.8.so linux-gate.so.1 => (0x00476000) libz.so.1 => /lib/libz.so.1 (0x00d9c000) libdl.so.2 => /lib/libdl.so.2 (0x002a8000) libm.so.6 => /lib/libm.so.6 (0x00759000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x002ad000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x0068d000) libpthread.so.0 => /lib/libpthread.so.0 (0x006f0000) libc.so.6 => /lib/libc.so.6 (0x00477000) /lib/ld-linux.so.2 (0x007f6000) Does it means that the .so file was not compiled correctly (in that case, it's a bug in my distribution package) or does it means that there are missing libraries on the linker command line for my particular program? Additionally, do you know how I can get a list on undefined symbols in an ELF file. I tried readelf -s but I can't find the missing symbol. Thank you. Mildred

  • The cost of passing by shared_ptr

    - by Artem
    I use std::tr1::shared_ptr extensively throughout my application. This includes passing objects in as function arguments. Consider the following: class Dataset {...} void f( shared_ptr< Dataset const > pds ) {...} void g( shared_ptr< Dataset const > pds ) {...} ... While passing a dataset object around via shared_ptr guarantees its existence inside f and g, the functions may be called millions of times, which causes a lot of shared_ptr objects being created and destroyed. Here's a snippet of the flat gprof profile from a recent run: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls s/call s/call name 9.74 295.39 35.12 2451177304 0.00 0.00 std::tr1::__shared_count::__shared_count(std::tr1::__shared_count const&) 8.03 324.34 28.95 2451252116 0.00 0.00 std::tr1::__shared_count::~__shared_count() So, ~17% of the runtime was spent on reference counting with shared_ptr objects. Is this normal? A large portion of my application is single-threaded and I was thinking about re-writing some of the functions as void f( const Dataset& ds ) {...} and replacing the calls shared_ptr< Dataset > pds( new Dataset(...) ); f( pds ); with f( *pds ); in places where I know for sure the object will not get destroyed while the flow of the program is inside f(). But before I run off to change a bunch of function signatures / calls, I wanted to know what the typical performance hit of passing by shared_ptr was. Seems like shared_ptr should not be used for functions that get called very often. Any input would be appreciated. Thanks for reading. -Artem

  • Why isn't the reference counter in boost::shared_ptr volatile?

    - by Johann Gerell
    In the boost::shared_ptr destructor, this is done: if(--*pn == 0) { boost::checked_delete(px); delete pn; } where pn is a pointer to the reference counter, which is typedefed as shared_ptr::count_type -> detail::atomic_count -> long I would have expected the long to be volatile long, given threaded usage and the non-atomic 0-check-and-deletion in the shared_ptr destructor above. Why isn't it volatile?

  • Memory leak using shared_ptr

    - by nabulke
    Both code examples compile and run without problems. Using the second variant results in a memory leak. Any ideas why? Thanks in advance for any help. Variant 1: typedef boost::shared_ptr<ParameterTabelle> SpParameterTabelle; struct ParTabSpalteData { ParTabSpalteData(const SpParameterTabelle& tabelle, const string& id) :Tabelle(tabelle), Id(id) { } const SpParameterTabelle& Tabelle; string Id; }; Variant 2: struct ParTabSpalteData { ParTabSpalteData(const SpParameterTabelle& tabelle, const string& id) :Id(id) { // causes memory leak Tabelle2 = tabelle; } SpParameterTabelle Tabelle2; string Id; };

  • How do I share usercontrols/functionality between sites?

    - by Jimmy Engtröm
    Hi We have two asp.net sites (based on episerver). Using Telerik Asp.net controls. We have some funtionality that we want to have availible in both sites. Right now one of the sites use webparts/usercontrols and the other uses usercontrols. Is there any way to share the functionality between these sites? What I would like is to be able to share usercontrols between the sites. /Jimmy

  • perl dynamic path given to 'use lib'

    - by Ed Hyer
    So, my code (Perl scripts and Perl modules) sits in a tree like this: trunk/ util/ process/ scripts/ The 'util' directory has, well, utilities, that things in the 'process/' dir need. They get access like this: use FindBin; use lib "$FindBin::Bin/../util"; use UtilityModule qw(all); That construct doesn't care where you start, as long as you're at the same level in the tree as "util/". But I decided that 'scripts/' was getting too crowded, so I created scripts/scripts1 scripts/scripts2 Now I see that this doesn't work. If I run a script 'trunk/scripts/scripts1/call_script.pl', and it calls '/trunk/process/process_script.pl', then 'process_script.pl' will fail trying to get the routines from UtilityModule(), because the path that FindBin returns is the path of the top-level calling script. The first ten ways I thought of to solve this all involved something like: use lib $path_that_came_from_elsewhere; but that seems to be something Perl doesn't like to do, except via that FindBin trick. I tried some things involving BEGIN{} blocks, but i don't really know what I'm doing there, and will likely just end up refactoring. But if someone has some clever insight into this type of problem, this would be a good chance to earn some points!
