  • In Perl, how can I iterate over the Cartesian product of multiple sets?

    - by nubie2
    I want to do permutation in Perl. For example I have three arrays: ["big", "tiny", "small"] and then I have ["red", "yellow", "green"] and also ["apple", "pear", "banana"]. How do I get: ["big", "red", "apple"] ["big", "red", "pear"] ..etc.. ["small", "green", "banana"] I understand this is called permutation. But I am not sure how to do it. Also I don't know how many arrays I can have. There may be three or four, so I don't want to do nested loop.

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • Can you have a web application project produce multiple DLLS?

    - by chris
    I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

  • How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

    - by Kendrick Ledet
    Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

  • multiple calls to realloc() seems to cause a heap corruption..

    - by Windindeed
    What's the problem with this code? It crashes every time. One time it's a failed assertion "_ASSERTE(_CrtIsValidHeapPointer(pUserData));", other times it is just a "heap corrpuption" error. Changing the buffer size affects this issue in some strange ways - sometimes it crashes on the "realloc", and other times on the "free". I have debugged this code many times, and there is nothing abnormal regarding the pointers. char buf[2000]; char *data = (char*)malloc(sizeof(buf)); unsigned int size = sizeof(buf); for (unsigned int i = 0; i < 5; ++i) { char *ptr = data + size; size += sizeof(buf); char *tmp = (char*)realloc(data, size); if (!tmp) { std::cout << "Oh no.."; break; } data = tmp; memcpy(ptr, buf, sizeof(buf)); } free(data); Thanks!

  • How to test that variable is not equal to multiple things? Python

    - by M830078h
    This is the piece of code I have: choice = "" while choice != "1" and choice != "2" and choice != "3": choice = raw_input("pick 1, 2 or 3") if choice == "1": print "1 it is!" elif choice == "2": print "2 it is!" elif choice == "3": print "3 it is!" else: print "You should choose 1, 2 or 3" While it works, I feel that it's really clumsy, specifically the while clause. What if I have more acceptable choices? Is there a better way to make the clause?

  • Is there a point to have multiple VS projects for an ASP.NET MVC application?

    - by mare
    I'm developing MVC application where I currently have 3 projects in solution. Core (it is supposed to be for Repositories, Business Classes, Models, HttpModules, HttpFilters, Settings, etc.) Data access (Data provider, for instance SqlDataProvider for working with SQL Server datastore - implements Repository interfaces, XmlDataProvider - also implements Repository interfaces but for local XML files as datastore) ASP.NET MVC project (all the typical stuff, UI, controllers, content, scripts, resources and helpers). I have no Models in my ASP.NET MVC project. I've just run into a problem because of that coz I want to use the new DataAnnotation feature in MVC 2 on my Bussiness class, which are, as said in Core, however I have I want to be able to localize the error messages. This where my problem starts. I cannot use my Resources from MVC project in Core. The MVC project references Core and it cannot be vice-versa. My options as I see them are: 1) Move Resources out but this would require correcting a whole bunch of Views and Controllers where I reference them, 2) Make a complete restructure of my app What are your thoughts on this? Also, Should I just move everything business related into Models folder in MVC project?? Does it even make any sense to have it structured like that, because we can just make subfolders for everything under MVC project? The whole Core library is not intended to ever be used for anything else, so there actually no point of compiling it to a separate DLL. Suggestions appreciated.

    - by Vishakha Kinjawadekar
    I am working on android geolocation application in that I have added marker for current location and want to add markers for other geopoints also. I have created objects of OverlayItem for other points and adding it to ItemizedOverlay like itemizedOverlay.addOverlay(overlayItem) and then adding it to mapOverlay.add(itemizedOverlay). For the current location geopoints getting from "Location" object and other points are hard-coded values. After executing it only current location marker is displayed not the other hardcoded points.How can I add marker for these geopoints and where? Thanks , Vishakha.

  • How do i create multiple URLs with /controller/action/ format?

    - by Angela
    I have several controller/actions where no :id needs to be passed. what I did with the first two was make a custom route defining the controller and action. I thought that the default would allow me to create controller/action.xml by using respond_to in the controller, but that doesn't appear to be the right way. How can I create controller/action URL's (some are .xml) without creating a special route with map.connect?

  • Is it possible to create a resource with multiple names in xaml?

    - by mos
    In a ResourceDictionary, is there any way to specify an alias for a resource? For example, <Color x:Key="BorderColor">#FF000000</Color> <Color x:Key="AlternateBorderColor">{StaticResource BorderColor}</Color> I don't really want another resource called "AlternateBorderColor", I would just like to be able to refer to the original resource by another name.

  • How to deal with multiple screensizes + dynamic controls in Android?

    - by chobo2
    Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

    I need to track the completion of tasks for users. I started by having a row called "first_login", "profile_complete", "other_thing_complete", etc... I'd like to combine these all into one row "activity_state". I just don't know how to properly store data in this field, and how to retrieve it. What kind of field should it be, and how should I read/write to it?

  • How can I use SQL Server's full text search across multiple rows at once?

    - by Morbo
    I'm trying to improve the search functionality on my web forums. I've got a table of posts, and each post has (among other less interesting things): PostID, a unique ID for the individual post. ThreadID, an ID of the thread the post belongs to. There can be any number of posts per thread. Text, because a forum would be really boring without it. I want to write an efficient query that will search the threads in the forum for a series of words, and it should return a hit for any ThreadID for which there are posts that include all of the search words. For example, let's say that thread 9 has post 1001 with the word "cat" in it, and also post 1027 with the word "hat" in it. I want a search for cat hat to return a hit for thread 9. This seems like a straightforward requirement, but I don't know of an efficient way to do it. Using the regular FREETEXT and CONTAINS capabilities for N'cat AND hat' won't return any hits in the above example because the words exist in different posts, even though those posts are in the same thread. (As far as I can tell, when using CREATE FULLTEXT INDEX I have to give it my index on the primary key PostID, and can't tell it to index all posts with the same ThreadID together.) The solution that I currently have in place works, but sucks: maintain a separate table that contains the entire concatenated post text of every thread, and make a full text index on THAT. I'm looking for a solution that doesn't require me to keep a duplicate copy of the entire text of every thread in my forums. Any ideas? Am I missing something obvious?

  • Why can't I display same object in multiple viewports?

    - by user288973
    Hi, I'm pretty new to OpenGL. Was playing around with some code but can't figure out why the following will not produce two viewports with the same object view. Heres the code: glViewport(0, windowHeight/2, windowWidth/2, windowHeight); glScissor(0, windowHeight/2, windowWidth/2, windowHeight); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective( 45.0, (GLfloat)(windowWidth/2)/(GLfloat)(windowHeight/2), 0.1f, 500.0 ); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT); drawParticleView(); glViewport(windowWidth/2, 0, windowWidth, windowHeight/2); glScissor(windowWidth/2, 0, windowWidth, windowHeight/2); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective( 45.0, (GLfloat)(windowWidth/2)/(GLfloat)(windowHeight/2), 0.1f, 500.0 ); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT); drawParticleView(); drawParticleView() just draws an array of rectangles. The problem is that the second viewport is a squashed representation of the first. My window width is 1280 and height 960. I'm obviously doing something wrong but what? Thanks
