• multiplayer / visitors interactions with Ruby on Rails?

  - by Jordi

  I want to have interactions between visitors on my site. Imagine a chat room. It basically involves getting the data from everyone and sending it to everyone, this can be done by ajax and what not but I wonder if there is something already there in the wild that would do the heavy lifting for me. I have to say that I got very lost once I start programming Ajax, dont even know how to make tests for it... I have found the Q42multiplayer library that looks like what I want but they use C# as backend. There is something similar or any other multiplayer thingy I can get some idea or rip some code from (the whole thing will be opensource) for Ruby on Rails?

• Perspective Rotation about Y axis

  - by N.A.Reddy

  Hello Experts, I have a 2D image and I want to create a anaglyph image for this single 2D image. To do this I need to create Left and Right views. I will considar my 2D image as Left view and I want to create Right View now. I came to know that the perspective rotation (about Y axis) and perspective skews will give the right image. I know that the perspective projection is related to 3D. Basically I am new to 3D programming. Can you plz explain how to do perspective rotation abuout Y-axis. And how can I apply this to my 2D image.I am using C++. Thank you verymuch N.A.Reddy.

• WPF Localization Using LocBaml: Handling Special Symbols

  - by Aryeh

  Hello, I’m dealing with localization of a WPF application (Visual Studio 2010 under Windows 7). I’ve just accomplished the whole process of localization using LocBaml tool, as explained in WPF Globalization and Localization Overview and in related posts. The target language is Italian (it-IT culture). When I run my application in Italian, I have a problem with interpretation of the special symbols of © and ™: they both appear there as a white question sign upon a black diamond-shaped background. The symbols © and ™ appear identically in both English and Italian CSV-files. I tried also the special letters (such as È, à etc.) that are present in Italian but absent in English, and they also are interpreted as the above diamond-shaped question. In Region and Language, I changed the system locale to Italian[Italy], restarted the PC and ran the application again – this helped me in the past to cope with a similar problem in localization of C++ applications under Windows XP, but now it didn’t help, either. Has somebody any idea what is the catch here?

• WCF Certificate issue

  - by Morgeh

  I am developing a WCF service on my local computer using Visual Studios built in ASP.NET development sever and I'm having issues creating and using temporary Certificates. I have created a cert call TempCA and added it to the Trusted Root Certificate folder and I have created another called SignedByCA which has been added to the personal folder. The service config file has been set up to use SignedByCA but when I run the service I get the following error. The certificate 'CN=SignedByCA' must have a private key that is capable of key exchange. The process must have access rights for the private key. I have tried using WinHttpCertCfg.exe to give other users access to the key but I have since found out that WinHttpCertCfg.exe has be deprecated in windows Vista. Has anyone had this issue before in a similar circumstance??

• in TFS can we customize the merge algorithm (conflict resolution)

  - by Jennifer Zouak

  In our case we want to igonore changes in code comment headers for generated code. In Visual Studio, we can change the merge tool (GUI that pops up) and use a 3rd party tool that is able to be customized to ignore changes (http://msdn.microsoft.com/en-us/library/ms181446.aspx). Great, so a file comparison no longer highlights code comments as differences. However when it comes time to checkin, the TFS merge algorith is still prompting us to resolve conflicts. Is there any way to better inform the merge conflict resolution algorithm about which changes are actually important to us? Or can we replace the algorithm or otherwise have it subcontract its work to a 3rd party?

• Project roles discovery

  - by Lirik

  I have a school project in which we're going to write a financial engine prototype by a group of 4 people. Most of us have never met each other before, so I'm trying to create a questionnaire to help us find the appropriate roles for each team-member. We have the following responsibilities: Database design Programming User interface design Training Documentation / technical writing Network design Project management Business analysis Testing And we have the following roles: Project Manager Developer Tester Business Analyst Our group has people with various experience: a full-time graduate student, an associate director at the CME (Chicago Mercantile Exchange), full-time professionals, etc. Do any of you know of any tools that would help build a questionnaire or do you have a reference to an online questionnaire that can help us identify the most suitable role(s) for each team member?

• Recursion and Iteration

  - by Doug

  What is the difference? Are these the same? If not, can someone please give me an example? MW: Iteration - 1 : the action or a process of iterating or repeating: as a : a procedure in which repetition of a sequence of operations yields results successively closer to a desired result b : the repetition of a sequence of computer instructions a specified number of times or until a condition is met Recusion - 3 : a computer programming technique involving the use of a procedure, subroutine, function, or algorithm that calls itself one or more times until a specified condition is met at which time the rest of each repetition is processed from the last one called to the first

• ASP.Net 2.0 Web application cannot find specified module.

  - by Brian Walker

  Recently my ASP.NET application quit working. It is local to my machine. It quit working after installing and uninstalling some third party developer tools. (I believe) I emptied out my directory and started adding modules until I narrowed it down to a managed C++ dll. When I load the dll into Dependency Walker it says that "c:\windows\winsxs\x86_microsoft.vc80.debugcrt_1fc8b3b9a1e18e3b_8.0.50727.762_x-ww_5490cd9f\MSVCM80D.DLL" loads fine, but "MSVCR80D.DLL" could not be found. However this dll exists in the same directory. The managed dll contains an embedded manifest and I am using Visual Studio 2005 service pack 1.

• Can HTTP URIs have non-ASCII characters?

  - by Cheeso

  I tried to find this in the relevant RFC, IETF RFC 3986, but couldn't figure it. Do URIs for HTTP allow Unicode, or non-ASCII of any kind? Can you please cite the section and the RFC that supports your answer. NB: For those who might think this is not programming related - it is. It's related to an ISAPI filter I'm building. Addendum I've read section 2.5 of RFC 3986. But RFC 2616, which I believe is the current HTTP protocol, predates 3986, and for that reason I'd suppose it cannot be compliant with 3986. Furthermore, even if or when the HTTP RFC is updated, there still will be the issue of rationalization - in other words, does an HTTP URI support ALL of the RFC3986 provisos, including whatever is appropriate to include non US-ASCII characters?

• Behavior of a pipe after a fork()

  - by Steve Melvin

  When reading about pipes in Advanced Programming in the UNIX Environment, I noticed that after a fork that the parent can close() the read end of a pipe and it doesn't close the read end for the child. When a process forks, does its file descriptors get retained? What I mean by this is that before the fork the pipe read file descriptor had a retain count of 1, and after the fork 2. When the parent closed its read side the fd went to 1 and is kept open for the child. Is this essentially what is happening? Does this behavior also occur for regular file descriptors?

• Exposing.NET assembly as COM 101

  - by Jan Zich

  I have trouble to expose a .NET assembly in COM. It seems that I must be missing some basic step because I think I followed all tutorials and documentation I found as well as common sense, but still when I do (in a test VBScript): Set o = CreateObject("MyLib.MyClass") It keeps saying that the object cannot be created. Here are the steps I have done: I have simple one method dummy class with no attributes. The class is in a class library which has "Make assembly COM-visible" ticked in Visual Studio. The class library is signed. The DLL is registered via RegAsm.exe with the /codebase parameter (I don’t want / cannot add the DLL to GAC). Just to be sure, I tried to copy the library to the same directory as the test VBScript, but it does not help. Edit: I should have mentioned that the I can instantiate the class in COM if I put the DLL into GAC.

• Informix & .NET

  - by Giuliano

  I'm connecting to Informix 6.5 using the IBM OLE DB Driver. Some clarification: Informix Dynamic Server Workgroup Edition. Please note that there are many versions of IDS/WE - it helps to be precise about which version you have. It might be something like 10.00.TC1; the version number could be as old as 7.xx.TCx, or as new as 11.50.TCx. If your server is not on Windows but on Unix - or is on 64-bit Windows - the letter 'T' would change to 'U' (32-bit Unix) or 'F' (64-bit - Unix or Windows), or even 'H' (a particular HP-UX configuration). When I try to create a dataset using the VS DataSet wizard, after clicking on test connection it tells me 'Base Table not found'? The OLEDB driver is the official one provided by IBM. The problem with the 'Table not found' dialog is that Visual Studio doesn't tell me the table name but only the error! Has anyone else had this problem?

• What Features Do You Want To See in .NET 5/C# 5?

  - by Randolpho

  .NET 4 and Visual Studio 2010 are finally here, along with a host of new features. But we wouldn't be who we are if we didn't long for a feature that didn't make the cut, or that was never even considered. So sound off and let the folks at Microsoft know: What features do you want to see in .NET 5? What features do you want to see in C# 5? F#? VB.NET? Before you vote to close: some may find this question too subjective to let stand, but there are other threads that have stood the test of time. Let this one stand as well.

• Problems with installing jcc and pylucene

  I'm trying to install pylucene on Windows XP. I installed JDK on C:\Programme\Java\jdk1.6.0_18 . I also installed Visual Studio C++ Express to have a C++ compiler.

• Why is my app running

  - by John Smith

  I have compiled my iPhone app with setting (Device, Release). I install it on the test machine and it runs with no problem. Here's the problem. The app is linked to a C++ library. The compilation on the simulator has no errors. However the device compilation produces 568 errors, mostly about different visibilities w.r.t AppDelegate.o. They all look like: QL::Error::~Error()has different visibility (default) in /QL/build/Release-iphoneos/libQLLibrary.a(abcd.o) and (hidden) in /Programming/ObjC/Second/build/Second.build/Release-iphoneos/FG.build/Objects-normal/armv6/AppDelegate.o Why is this, and how can I stop the errors anyway?

• Spinlocks, How Much Useful Are They?

  - by unknown

  How often do you find yourself actually using spinlocks in your code? How common is it to come across a situation where using a busy loop actually outperforms the usage of locks? Personally, when I write some sort of code that requires thread safety, I tend to benchmark it with different synchronization primitives, and as far as it goes, it seems like using locks gives better performance than using spinlocks. No matter for how little time I actually hold the lock, the amount of contention I receive when using spinlocks is far greater than the amount I get from using locks (of course, I run my tests on a multiprocessor machine). I realize that it's more likely to come across a spinlock in "low-level" code, but I'm interested to know whether you find it useful in even a more high-level kind of programming?

• Return a pointer to a char array in C

  - by snitko

  I've seen a lot of questions on that on StackOverflow, but reading the answers did not clear that up for me, probably because I'm a total newbie in C programming. Here's the code: #include <stdio.h> char* squeeze(char s[], char c); main() { printf("%s", squeeze("hello", 'o')); } char* squeeze(char s[], char c) { int i, j; for(i = j = 0; s[i] != '\0'; i++) if(s[i] != c) s[j++] = s[i]; s[j] = '\0'; return s; } It compiles and I get segmentation fault when I run it. I've read this faq about about returning arrays and tried the 'static' technique that is suggested there, but still could not get the program working. Could anyone point out exactly what's wrong with it and what should I be paying attention in the future?

• All possible combinations of n items selected randomly from a set of x items (algorithm)

  - by SubPortal

  I have a set of x string items e.g("A","B","C","D","E","F") I need to know the formula that calculates how many combinations of n items and what is the algorithm that generates all possible combinations e.g if we need to select 4 items from the list randomly. those 4 items could be: ("A","B","C","D") or ("A","B","C","E") or ("A","B","C","F") or ("A","B","D","E") ...etc I need the formula that calculates how many sets of items will be generated without repetition, that is we consider ("A","B","C","D") as one of the resulted combinations we cannot consider the same items as another resultant combination with replacing the positions of the items in the set like ("A","B","D","C") Also I need the algorithm that generates all possible combinations in any programming language. [C#,VB.NET,Java,C++] Thank you for any help.

• How to compare two TXT files before send it to SQL

  - by adopilot

  I have to handle TXT dat files which coming from one embed device, My problem is in that device always sending all captured data but I want to take only difrences between two sending and do calculation on them. After calculation I send it to SQL using bulkinsert function. I want to extract data which is different according to first file I got from device. Lats say that device first time device send data like this in some.dat (ASCII) file 0000199991 0000199321 0000132913 0000232318 0000312898 On second calls to get data from device it is going to return all again (previous and next captured records) something like this 0000199991 0000199321 0000132913 0000232318 0000312898 9992129990 8782999022 2323423456 But this time I do want only to calculate and pass trough data added after first insert.

• Why is VB so popular? [closed]

  - by aaaidan

  To me, Visual Basic seems clumsy, ugly, error-prone, and difficult to read. I'll let others explain why. While VB.net has clearly been a huge leap forward for the language in terms of features, I still don't understand why anyone would choose to code in VB over, say, C#. However, I still see (what seems to be) the vast majority of commercial web apps from "MS shops" are built in VB. I could stand corrected on this, but VB still seems more popular than it deserves. Can anyone help answer any (or all) of these questions: Am I missing something with VB? Is it easier to learn, or "friendlier" than C#? Are there features I don't know about? Why is VB/VB.net so frequently used today, especially in web projects?

• SQL Server Upgrade 'Developer > Enterprise'

  - by JD

  Hey guys, My company purchased Visual Studio Pro 2008 last year, which had a 'free' copy of SQL Server Developer, which I have been using for development. We are wanting to upgrade the copy of developer edition to enterprise (As we now want to use the server as a production server), and have purchased the licenses for this. Now... Morally we're in the clear... However does this comply with MS licensing T&C's? We have Developer installed how we want it, and don't really want to uninstall SQL Server Dev just to install SQL Server Ent. Is there a way to transfer the license key to our Enterprise key without having to reinstall? Thanks, JD

• Passing Custom headers from .Net 1.1 client to a WCF service

  - by sreejith

  I have a simple wcf service which uses basicHttp binding, I want to pass few information from client to this service via custom SOAP header. My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header. Tried to override "GetWebRequest" and added custom headers in the proxy but for some reason when I tried to access the header using "OperationContext.Current.IncomingMessageHeaders.FindHeader" it is not thier. Any idea how to solve this prob? This is how I added the headers protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("tesData", "test"); return request; }

• Facebook API - Get comments

  - by Simon R

  Our business has a Facebook Fan Page. The fan page doesn't seem to generate any emails to us when updates are made to the page, whether someone adds a new status or someone comments on one of the statuses etc. Currently, we are running a very crude script to grab the content of the page and then use regular expressions to get the information we require. Obviously this is not fool proof and I'm looking into alternatives to this method. I've been looking at the facebook API and wonder if the rest server might be an option. I cannot, however, seem to find out how to return information of fan page statuses and their comments. Is anyone able to direct me how to use the API to retrieve this information. I am an admin of the fan page. The programming language I'm using is PHP. Many thanks.

• How to spot empty parking spaces?

  - by mithila

  I want to do a final year B.Sc project on parking space detection. Can anybody give me some link related to it? Any text-book, tutorial or anything? What would be prerequisite for this project? What type of skills(programming/math) are needed? What are the initial steps to do? What type of readings(algorithms of image processing) are needed? Detail added in comments: i'm going to use camera, not infrared. i would like to use still images, or one camera which captures images from a parking lot. i think reak-time processing will be tough, at this moment i just need to start the project. so still images will work fine. but later it may b a real-time project

• Bounce Email handling with PHP??

  - by mcfadder_09

  I am really new to this (not new to php). Here is my scenario: I have 2 emails accounts. [email protected] and [email protected]. I want to send email to all my users with [email protected] but then "reply to" [email protected] (until here, my php script can handle it). When, the email cant be sent, it sent to [email protected], the error message could be 553 (non existent email ...) etc. My question is: How do I direct all those bounce emails (couldn't sent emails) to [email protected] through a handling script to check for the bounce error codes? What programming language should I be for the "handling script"? What would the "handling script" looks like? Can give a sample? OR:(Big Question) What are the procedures I should follow to handle the bounce email ??
