  • Computing e^(-j) in C..

    - by Erkan H
    I need to compute imaginary exponential in C. As far as I know, there is no complex number library in C. It is possible to get e^x with exp(x) of math.h, but how can I compute the value of e^(-j), where j = sqrt(-1)?

  • About the armlink behavior when the linked object is not explicitly used by the main executable

    - by thincal
    I want to link the example with liba.so, and also the example is NOT using anything inside the liba.so ... armlink --userlibpath /mylib/lib liba.so --fpic --shared -o example main.o demo.o So finally I got nothing from: readelf -d example | grep NEEDED, it seems that armlink do some optimization to remove the linked library which is not really used by the "example" ? If I want to let the liba.so be always linked into example, what need I do with armlink options ? Any information is very appreciated ;)

  • Embedding a Jar into a C# Form

    - by clone1018
    Ok this situation is a bit difficult. But I am trying to embed a Java Jar into a C# form. Not as a new window or new process. The Jar will be a game that uses the LWJGL library. The C# Form will be a "wrapper" for it with tools and more. Anyone have any ideas? Is this even possible?

  • Easy way to add custom prerequisite in clickonce publish (VS 2010)

    - by Maciej
    I would like to add Infragistics dlls as custom prerequisite when publishing my project. I've read about that: http://msdn.microsoft.com/en-us/library/aa730839%28VS.80%29.aspx But this seems to be a bit complicated... I wonder if exists a bit simple way to archive that (eg by passing URL to setup.exe or such) ? EDIT This Might be also interesting: http://www.codeproject.com/KB/aspnet/Add_Custom_Prerequisite.aspx?msg=2520811 will check and let you know...

  • How To Read C# Code From Java Background

    - by ChloeRadshaw
    I come from a Java background and have been using C# for the last year - So far the API docs I use are at MSDN (http://msdn.microsoft.com/en-us/library/ms132397.aspx). I tend to use the lightweight C# docs. What annoys me about that is that I don't see one page with details of the class, a list of members, a list of methods and properties like I would with a Java API definition. Is this possible?

  • Is there a sorted_vector class, which supports insert() etc.?

    - by Frank
    Often, it is more efficient to use a sorted std::vector instead of a std::set. Does anyone know a library class sorted_vector, which basically has a similar interface to std::set, but inserts elements into the sorted vector (so that there are no duplicates), uses binary search to find elements, etc.? I know it's not hard to write, but probably better not to waste time and use an existing implementation anyway.

  • Reading a SquashFS archive

    - by p-static
    (SquashFS is a compressed filesystem - http://en.wikipedia.org/wiki/SquashFS) I'm looking for a way to read a SquashFS filesystem from a program. So far, I've know about the in-kernel drivers for it, but I'm sure that a userspace library for it must exist somewhere. Any language would be fine, but C is preferred. Just mounting the filesystem and using it that way is technically possible, but I'd rather avoid that route because the application I'm looking at would involve working with at least a few dozen archives at any given time.

  • (vqmod) Error: Could not load language total/sub_total

    - by Steve
    I have moved my Opencart website to a new host, and I receive the error: Notice: Error: Could not load language total/sub_total! in .../vqmod/vqcache/vq2-system_library_language.php on line 41 How do I resolve this? I have tried renaming vqmod/xml to vqmod/xml.bad, with no result. I have tried renaming /vqmod/vqcache to /vqmod/vqcache.bad, with no result. Update: In \system\library\language.php, I commented out an else branch which resulted in an application exit.

  • How to Block images (img tags) from an iFrame?

    - by ramayac
    Hello, Im searching for ideas to solve the following problem: I'm loading an URL (any for that matter) into an iFrame, and then block (server side) all image tags, o object tags before sending the page to the client. -- What I was thinking to do is: fetching the URL, and then manipulating the fetched content using a Java library (any recomendation on that matter?). And after that, send the modify content to que client. Would that be the best approach to solve this problem? suggestions are wellcome :)

  • (iphone) how can I tell I need a 3.0 + iOS installed device when looking at apple doc?

    - by Eugene
    Hi, I've seen iphone related open source library which says something like, "You need 4.0+ iOS build environment but the code will run on 3.0+ iOS device." I wonder how those two requirements can differ and how can I tell a minimum 'device' iOS version which a certain api would need. For instance I want to use UIGestureRecognizer but the apple doc says it's 3.2+, but I want my app run on 3.12+. Is there a difference between build os requirement and device os requirement to run an app? Thank you

  • Curl CONNECTION OPTIONS in C++

    - by cinek1lol
    HI I'd like to know how to check out the speed of a file being uploaded in real time using the curl library in c++. This is what I have written: curl_easy_getinfo(curl,CURLINFO_SPEED_UPLOAD,&c); But the manual says that it shows average speed, but even this doesn't seem to work with me, because I can only see a 0. There is one more thing: How to set an upload limit that works, because if I write this: curl_easy_setopt(curl, CURLOPT_MAX_SEND_SPEED_LARGE, 100); I get an error 502 message

  • This is a valid C code but not a valid C++ code?

    - by claws
    In some library I'm using (written in C) its StorePGM(image, width, height, filename) char *image; int width, height; char *filename; { // something something } All functions are defined this way. I never seen such function definitions in my life. They seem to be valid to MSVC but when I compile it as C++ it gives errors. What is it? some kind of old version C?

  • How do you take snapshots of an iPhone screen within a C# application?

    - by Kovu
    I would like to be able to take a snapshot of the screen of an attached iPhone from within a C# application I am writing for Windows, similar to how Xcode's Organizer takes snapshots. I have heard that you can use ITunesMobileDevice.dll to communicate with an attached iPhone, but I don't know how to take snapshots using this library. Does anyone have an idea how to do this?
