• C++: Copying to dereferenced pointer...

  - by bbb

  Hi. I currently have a weird problem with a program segfaulting but im not able to spot the error. I think the problem boils down to this. struct S {int a; vector<sometype> b;} S s1; // fill stuff into a and b S* s2 = new S(); *s2 = s1; Could it be that the final copying is illegal in some way? Im really confused right now... Thanks

• Make network changes permanent - C++

  - by pparescasellas

  I need to allow an external client to change the IP of the Linux machine where the program is running (C++). I already know how to list all the local interfaces and the current IPs assigned to them. I also know how to programatically change said IPs. What I need to know is how to make this change permanent so, if the machine reboots, it keeps the same network configuration. What's the best way to do this? Manually parsing /etc/network/interfaces? Calling some linux command? Edit: I'm using Debian. Thanks!

• Email delivery failure - bounceback address

  - by user808532

  I've been looking for documentation on the standard behaviour for mail servers who fail to deliver their mail. I want the 'From' field to be different from the account that receives emails when there is a delivery failure. E.g. My program sends an email from '[email protected]', and on failure to deliver I want to be sent the delivery failure bounceback at '[email protected]'. Is this accomplished by setting the reply-to? Or should I login with the 'failedemails' account and therefore it will receive the email back? Thanks.

• How do you deal with non-logical people in the workplace?

  - by unrealtrip

  I ask this because you are probably the best audience I could think of. I program for a living, and it goes hand in hand with my personality type which is likely true for most of us, as such I live and work in the world of logic and logical decisions. A problem I have is in dealing with people that live and work in a world of emotional responses and reactions that typically make no sense, or have any real bearing on any given situation. What is the trick to dealing with these people? It is nothing but an act of futility, leading to utter exasperation dealing with people like this when attempting to get them to understand some pretty basic concepts. How do you do it?

• Processing a method after the view has loaded..

  - by Susanth

  Hi ! I have implemented a subview which is supposed to load immediately when I click a button in the parent view. After loading the subview(which is basically holding an activityindicator), the program is supposed to process a method(which gets data from a server, so takes time) in it. However, I am unable to do it. What happens now is, when I click the button on the parent view, it processes the method first and only after that does the subview load on screen. Why is this so? Is there any specific functions I could use to make my method load only after the view has loaded?

  I am using GUI2Exe to compile my python/pygame, game to a .exe I have a problem with the font module. using python 2.7 and the py2exe option in GUI2Exe I have updated python, pygame and py2exe with the 2.7 versions. My program runs fine but after I compile it with py2exe I get this. Here is the error I get: Fatal Python error: (pygame parachute) Segmentation Fault This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. My game starts off as a console and that part runs. But as soon as the display starts I get the crash. Thanks

• How do I create a certain control using Windows Forms in Visual C++?

  - by Dalze

  I am new to using Windows Forms in C++ (and just in general), and I am not exactly sure of the name or if it's even possible to do. Currently I am currently working on a school project in which we must make a program for an imaginary bookstore. I am trying right now to make a sort of list that shows what the "customer" is buying. I have to make it sort by price and ISBN and any other variable that the book has. In essence I am trying to make something like the following: I just need to know how to get started. I can't figure out what the name of the control is or how to even get it to sort every time the user clicks on the header.

• strategy to allocate/free lots of small objects

  - by aaa

  hello I am toying with certain caching algorithm, which is challenging somewhat. Basically, it needs to allocate lots of small objects (double arrays, < 256 elements), with objects accessible through mapped value, map[key] = array. time to initialized array may be quite large, generally more than 10 thousand cpu cycles. By lots I mean around gigabyte in total. objects may need to be popped/pushed as needed, generally in random places, one object at a time. lifetime of an object is generally long, minutes or more, however, object may be subject to allocation/deallocation several times during duration of program. What would be good strategy to avoid memory fragmentation, while still maintaining reasonable allocate deallocate speed? I am using C++, so I can use new and malloc. Thanks. I know there a similar questions on website, http://stackoverflow.com/questions/2156745/efficiently-allocating-many-short-lived-small-objects, are somewhat different, thread safety is not immediate issue for me.

• Can JQuery/JavaScript be used to write a substantial client side application?

  - by Ian

  I have an unusual situation - I have an embedded video streaming device with a complicated UI, and I need to use an embedded web server to reproduce that UI through a web browser. I'm thinking of using JavaScript/JQuery on a C++ backend (I am NOT coding all this myself, I need to hire people for the grunt work). The embedded web server is much less powerful than a PC, so I want to write an application that runs the entire UI in the browser, and only communicates with the server to pass new program settings back and forth, get status updates from the device, and control video playback. In other words, the client gets one big page or a small number of big pages (effectively downloading the application), the application maintains significant local memory storage, and once the pages are first loaded the server never sends anything layout-related. The application has two rows of tabs to navigate ~40 menu pages, drag-and-select controls to pick cells in a grid, sorted lists, lots of standard data entry options, and it should be able to control up to 16 embedded video players at once (preferably VLC). Is this possible in JavaScript/JQuery with a C++ backend?

• squid url_rewrite with cookie

  - by geekGod

  I have a squid 3.0 deployed which has a url_rewriter program which rewrites certain HTTP requests. I now need to modify this prpogram to rewrite along with the cookie setting code. As much as I have seen the url_rewrite_program documentation, it appears that I may not be able to set a cookie along with the 302 response. Is this correct? Can i set a cookie in the redirect response or would this require modifying the squid code. Appreciate any help in this regard!

• What is wrong with the below statement(C#3.0 / Lambda)

  - by Newbie

  what is wrong in the below Enumerable.Range(0, objEntityCode.Count - 1).Select(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; }) .ToArray(); Throwing error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. But this works Enumerable.Range(0, objEntityCode.Count - 1).ToList().ForEach(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; } ); Using C#3.0. Purpose: I am learning LINQ / LAMBDA and trying to do the same program in different way. Thanks.

• (Win Api) Check if an external application window is on the taskbar

  - by Jorge Branco

  Hello. I'd like to know if it's possible to know if an external application has an window that is showing up on the taskbar. I have a program that sometimes shows up an error message and it appears on the taskbar. If I "close" the message, it will go invisible, but from what I've seen it still exists. So the only way for me to know if that window is visible and thus "clickable" is to check if it is being shown on the taskbar or not. How can I do this? Thanks

• Why does this C++ char array seem to be able to hold more than its size?

  - by Phenom

  #include <iostream> using namespace std; typedef struct { char streetName[5]; } RECORD; int main() { RECORD r; cin >> r.streetName; cout << r.streetName << endl; } When I run this program, if I enter in more than 5 characters, the output will show the whole string I entered. It does not truncate at 5 characters. Why is that? How can I get this to work correctly?

• BufferedInputStream.read(byte[]) Causes problems. Anyone have this problem before?

  - by K-RAN

  Hello! I've written a Java program that downloads audio files for me and I'm using BufferedInputStream. The read() function works fine but is really slow so I've tried using the overloaded version using byte[]. For some reason, the audio becomes lossy and strange after download. I'm not totally sure what I'm doing wrong so any help is appreciated! Here's the simplified, sloppy version of the code. BufferedInputStream bin = new BufferedInputStream((new URL(url)).openConnection().getInputStream()); File file = new File(fileName); FileOutputStream fop = new FileOutputStream(file); int rd = bin.read(); while(rd != -1) { fop.write(rd); rd = bin.read(); }

• Writing a C++ wrapper for a C library

  - by stripes

  I have a legacy C library, written in an OO type form. Typical functions are like: LIB *lib_new(); void lib_free(LIB *lib); int lib_add_option(LIB *lib, int flags); void lib_change_name(LIB *lib, char *name); I'd like to use this library in my C++ program, so I'm thinking a C++ wrapper is required. The above would all seem to map to something like: class LIB { public: LIB(); ~LIB(); int add_option(int flags); void change_name(char *name); ... }; I've never written a C++ wrapper round C before, and can't find much advice about it. Is this a good/typical/sensible approach to creating a C++/C wrapper?

• Visual Studio C++ adds "junk" to my programs

  - by sub

  I have looked into the binaries produced by MSVC 2010 from my source code, and saw everything being filled with "junk". I don't know how to explain, but my executables are being added too much unnecessary information, like: Lots of Microsoft default error messages, I don't want them XML schema settings (Why!?) Other things not important for the execution of the main program How can I stop MSVC doing this? Do I have to switch to GCC? In all other programs (written in C++ too, from Word processors to games), this junk simply doesn't exist.

• MediaType of REST

  - by user357243

  Hi, I am beginner in REST web services. I wrote a program of REST to display the HTML or XML. The @Path annotation's value is @Path("{typeDocument}"). There are two methods for GET : @GET @Produces(MediaType.TEXT_XML) public String getXml(@PathParam("typeDocument") String typeDocument) to display XML file, and @GET @Produces(MediaType.TEXT_HTML) public String getHtml(@PathParam("typeDocument") String typeDocument) to display HTML. The browser Firefox always excutes getHtml() when URL is either http://localhost:8080/sources/html or localhost:8080/sources/xml But IE always excutes getXml(). How to excute the correct method, as defined by URL, in different browser ? Thanks a lot.

• A better way of representing File Attachment into a list(c#3.0)

  - by Newbie

  I have written List<Attachment> lstAttachment = new List<Attachment>(); //Check if any error file is present in which case it needs to be send if (new FileInfo(Path.Combine(errorFolder, errorFileName)).Exists) { Attachment unprocessedFile = new Attachment(Path.Combine(errorFolder, errorFileName)); lstAttachment.Add(unprocessedFile); } //Check if any processed file is present in which case it needs to be send if (new FileInfo(Path.Combine(outputFolder, outputFileName)).Exists) { Attachment processedFile = new Attachment(Path.Combine(outputFolder, outputFileName)); lstAttachment.Add(processedFile); } Working fine and is giving the expected output. Basically I am attaching the file to the list based on whether the file is present or not. I am looking for any other elegant solution than the one I have written. Reason: Want to learn differnt ways of representing the same program. I am using C#3.0 Thanks.

• How to encode(represent) an ornament?

  - by Daniyar

  I would like to find a numeric representation of kazakh national ornaments for generating new ones. The ornaments essentially consist of combinations of relatively basic ornaments. Usually the ornaments are symmetrical. Here are few examples of basic elements: (The images are a bit distorted) And this is an example of a more complex ornament: How could I encode an ornament's representation in as few numbers as possible? So that I could write a program that would generate an ornament, given some sequence of numbers Any ideas are appreciated. As I write this, I have thought that generating images of snowlfakes may be somewhat relevant, although it's possibly just a fractal.

• .NET applications sometimes doesn’t work on Windows CE

  - by KZChris

  Hi, I write applications for Windowe ME and CE in C# .NET 2.0. Sometimes I’ve got problems because applications don’t work on some navigation devices. On Windowe ME it is not problem because .NET can be installed from a cab, but on most Windows CE devices it is impossible because after soft reset all changes disappear. I found out that in most difficult cases good solution is to put all dll-s belonging to .NET installation cab in the folder where the application runs and everything work well. However there are some devices for example Navroad NR460 (Windows CE 5.0) on which none of .NET applications work (it is funny because previous and next version of that navigation works well). I didn’t found on this device cgacutil.exe program. Is this possible to force the device to run any .NET application without installing the Windows again? What should I try to do to check if running .NET a applications is possible? What conditions should be fulfilled to run easiest application written even in .NET 1.0

• Solve Physics exercise by brute force approach..

  - by Nils

  Being unable to reproduce a given result. (either because it's wrong or because I was doing something wrong) I was asking myself if it would be easy to just write a small program which takes all the constants and given number and permutes it with a possible operators (* / - + exp(..)) etc) until the result is found. Permutations of n distinct objects with repetition allowed is n^r. At least as long as r is small I think you should be able to do this. I wonder if anybody did something similar here..

• Putting a variable inside a string (python)

  Hi I am quite new to python and this is probably quite a basic question but the help would be much appreciated. I would like to put an int within a string. This is what I am doing at the moment.. end = smooth(data,window_len=40) plot.plot(time[0:len(end)],end) plot.savefig('hanning(40).pdf') #problem line I have to run the program for several different numbers instead of the two 40's. So I'd like to do a loop but inserting the variable like this doesn't work: plot.savefig('hanning',num,'.pdf') Thanks!
