  • Some clarification on rvalue references

    - by Dennis Zickefoose
    First: where are std::move and std::forward defined? I know what they do, but I can't find proof that any standard header is required to include them. In gcc44 sometimes std::move is available, and sometimes its not, so a definitive include directive would be useful. When implementing move semantics, the source is presumably left in an undefined state. Should this state necessarily be a valid state for the object? Obviously, you need to be able to call the object's destructor, and be able to assign to it by whatever means the class exposes. But should other operations be valid? I suppose what I'm asking is, if your class guarantees certain invariants, should you strive to enforce those invariants when the user has said they don't care about them anymore? Next: when you don't care about move semantics, are there any limitations that would cause a non-const reference to be preferred over an rvalue reference when dealing with function parameters? void function(T&); over void function(T&&); From a caller's perspective, being able to pass functions temporary values is occasionally useful, so it seems as though one should grant that option whenever it is feasible to do so. And rvalue references are themselves lvalues, so you can't inadvertently call a move-constructor instead of a copy-constructor, or something like that. I don't see a downside, but I'm sure there is one. Which brings me to my final question. You still can not bind temporaries to non-const references. But you can bind them to non-const rvalue references. And you can then pass along that reference as a non-const reference in another function. void function1(int& r) { r++; } void function2(int&& r) { function1(r); } int main() { function1(5); //bad function2(5); //good } Besides the fact that it doesn't do anything, is there anything wrong with that code? My gut says of course not, since changing rvalue references is kind of the whole point to their existence. And if the passed value is legitimately const, the compiler will catch it and yell at you. But by all appearances, this is a runaround of a mechanism that was presumably put in place for a reason, so I'd just like confirmation that I'm not doing anything foolish.

  • Greasemonkey - jQuery not loading

    - by Sid
    Hi, I tried to load a copy of jQuery 1.3.2 from jquery.com (because it seems 1.4.0+ aren't treated too well by GM) using @require. Even after I uninstall and reinstall the script, GM does not copy jquery-1.3.2.js to my gm_scripts folder like it should. Tried this almost 10 times today. Also, when I click on "Manage Scripts", it shows my script as running on * even though I've added @include for http://www.catholicon.in/* I'm using the latest updates on both FF 3.6 and GM 0.8 Thanks

Also, are there others which are key to building ASP.NET applications?

  • Validate Strong Name of Running Assembly

    - by Kyle Rozendo
    Is it possible for one to check the strong name of a .NET application that is already currently running separately from your own running applications process? EDIT: For clarification, a solution that does not require a hard coded path to the executing assembly would be the most ideal solution. EDIT #2: Is there any way to do this without using reflection?

  • Vertical text alignment in Crystal Reports?

    - by George Mauer
    In the Crystal Reports editor that comes with Visual Studio (2008) is it possible to align text to the center of a text box rather than to the top? I can't find the option anywhere and a Google search is not encouraging but I just can't bring myself to believe that they would not include such an obvious feature.

  • Log4j show package name

    - by Stephane Grenier
    Right now for my ConversionPattern I have: log4j.appender.A1.layout.ConversionPattern=%d{yyyy MMM dd HH:mm:ss,SSS} %5p [%t] (%F:%L) - %m%n What I'd like to do is also include the full package name with the class (%F:%L) but I can't find any config to do so in the docs. I do understand that this will be slower, but it's only for debugging and not when the system will be in production.

  • Can't upload images with Magento 1.4 on Windows/IIS

    - by Jason
    Everything else works in Magento 1.4 but I can't upload images. Running on Windows/IIS. I know it isn't officially supported but seems odd that everything works but something as simple as image uploads. Tried updating the media path and that is correct. Also updated permissions on directories, but nothing has worked. Any other ideas to get this to work? thanks

  • Best PHP timezone list

    - by jimbo
    I have looked over the PHP list of supported timezones, but the whole list is a little long to include in a drop-down menu, for the user to select his or her timezone. Is there a list with the main city/area on that can be used? My geography is terrible and add that to not knowing all the area and which timezone they fall into it could be a long day to construct the list my self! Thanks in advance

  • How can I prevent segmentation faults in my program?

    - by worlds-apart89
    I have a C assignment. It is a lot longer than the code shown below, and we are given the function prototypes and instructions only. I have done my best at writing code, but I am stuck with segmentation faults. When I compile and run the program below on Linux, at "735 NaN" it will terminate, indicating a segfault occurred. Why? What am I doing wrong? Basically, the program does not let me access table-list_array[735]-value and table-list_array[735]-key. This is of course the first segfault. There might be more following index 735. #include <stdio.h> #include <stdlib.h> typedef struct list_node list_node_t; struct list_node { char *key; int value; list_node_t *next; }; typedef struct count_table count_table_t; struct count_table { int size; list_node_t **list_array; }; count_table_t* table_allocate(int size) { count_table_t *ptr = malloc(sizeof(count_table_t)); ptr->size = size; list_node_t *nodes[size]; int k; for(k=0; k<size; k++){ nodes[k] = NULL; } ptr->list_array = nodes; return ptr; } void table_addvalue(count_table_t *table) { int i; for(i=0; i<table->size; i++) { table->list_array[i] = malloc(sizeof(list_node_t)); table->list_array[i]->value = i; table->list_array[i]->key = "NaN"; table->list_array[i]->next = NULL; } } int main() { count_table_t *table = table_allocate(1000); table_addvalue(table); int i; for(i=0; i<table->size; i++) printf("%d %s\n", table->list_array[i]->value, table->list_array[i]->key); return 0; }

  • How do I get rid of LD_LIBRARY_PATH at run-time?

    - by Kjir
    I am building a C++ application that uses Intel's IPP library. This library is installed by default in /opt and requires you to set LD_LIBRARY_PATH both for compiling and for running your software (if you choose the shared library linking, which I did). I already modified my configure.ac/Makefile.am so that I do not need to set that variable when compiling, but I still can't find the shared library at run-time; how do I do that? I'm compiling with the -Wl, -R/path/to/lib flag using g++

    Hi, When writing a Maven plugin, you can configure various parameters within the mojo class, e.g. /** * The path to the properties files. * * @parameter expression="${project.build.directory}" */ private File buildDir; Is there a reference that lists all the available project properties (e.g. ${project.build.directory})? For example, how do I get the value of the resources directory? Thanks, Don
