• Suggested C++ books?

  - by Josh Bradley

  Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

• Animate 3D model programmatically-where to start?

  - by amile

  I am having a task to create a 3D model face that can talk like humans.without having any knowledge about 3D modeling. I have no clue where to start.I have searched a lot and find some of these things.OpenGL,WebGL,XNA and other similar tool can be helpful. please guide me where to start a step by step approach and which platform is better as i have programming background in JAVA. here is an idea what I need to do https://docs.google.com/viewer?a=v&pid=gmail&attid=0.2&thid=13f65486a46a1f67&mt=application/pdf&url=https://mail.google.com/mail/?ui%3D2%26ik%3D49f1f393c6%26view%3Datt%26th%3D13f65486a46a1f67%26attid%3D0.2%26disp%3Dsafe%26realattid%3Df_hi6ylzbv2%26zw&sig=AHIEtbQc8KQNHdprmEnL4UXyD3ox8vlKKQ

• Suggestions for a C++ IDE?

  - by AedonEtLIRA

  I know this is is a shifty question and really isn't easy to answer, but bare with me. For a while now I have been using Eclipse and doing Java programming. Now that I reach a point where I'm comfortable in Java, I wish to move on back into C++ and actually make something more than a single class that prints to terminal; and work in OpenGL :). So I wonder if anybody has a recomendation of IDE's that resemble or are as fluid as Eclipse? I am aware that Eclipse has a C++ plugin, but it really doesn't feel user friendly (at least to a pampered java programmer!). I have (I think I still have it?) a copy of Visual Studio 2005, but want to see if anyone has any better ideas. Thanks ~Aedon

• how to make a BufferedReader in C

  - by peiska

  I am really new programming in C. How can i do the same in C, maybe in a more simple way then the one a do in Java. Each line of the input have to Integers: X e Y separated by a space. 12 1 12 3 23 4 9 3 InputStreamReader in = new InputStreamReader(System.in); BufferedReader buf = new BufferedReader(in); int n; int k; double sol; String line =""; line=buf.readLine(); while( line != null && !line.equals("")){ String data [] = line.split(" "); n = Integer.parseInt(data[0]); k = Integer.parseInt(data[1]); calculus (n,k); line = buf.readLine(); }

• First and last window don't show up.

  - by SirGregg

  Hi, I'm creating a WinApi application for my programming course. The program is supposed to show an LED clock using a separate window for each 'block'. I have figured most of it out, except for one thing: when creating the two-dimensional array of windows, the first and last window never show up. Here's the piece of code from the InitInstance function: for (int x=0;x<8;x++) for (int y=0;y<7;y++) { digitWnd[x][y] = CreateWindowEx((WS_EX_LAYERED | WS_EX_TRANSPARENT | WS_EX_NOACTIVATE | WS_EX_STATICEDGE), szWindowClass, szTitle, (WS_POPUP| WS_BORDER), NULL, NULL, NULL, NULL, dummyWnd, NULL, hInstance, NULL); ShowWindow(digitWnd[x][y], nCmdShow); UpdateWindow(digitWnd[x][y]); } The same loop bounds are used everytime I interact with the windows (set position and enable/disable). All the windows seem to be working fine, except for digitWnd[0][0] and digitWnd[7][6]... Any ideas as to what is happening?

• How to create a static delegate from main-viewcontroller?

  - by geforce

  Hi, hope someone can help me on learning some new stuff about delegates in iOS-programming. I have a "MainViewController" which is the first VC when the app starts. I´ve a kind of modelselection with different UIImageViews and after choosing one of them, i´m pushing a new VC. I want to handle the modelChoice with a delegate, so all other viewControllers can listen to that and act based on the users choice. But does that mean that i have to alloc a new instance of that "MainViewController" in every VC? Whats the solution on that? How do i create (i think its called) static delegate? Would be great to learn that.. Thanks for sharing..

• Modifying an image with OpenGL ?

  - by chmike

  I have a device to acquire XRay images. Due to some technical constrains, the detector is made of heterogeneous pixel size and multiple tilted and partially overlapping tiles. The image is thus distorted. The detector geometry is known precisely. I need a function converting these distorted images into a flat image with homogeneous pixel size. I have already done this by CPU, but I would like to give a try with OpenGL to use the GPU in a portable way. I have no experience with OpenGL programming, and most of the information I could find on the web was useless for this use. How should I proceed ? How do I do this ? Image size are 560x860 pixels and we have batches of 720 images to process. I'm on Ubuntu.

• How to create an iPad directory view like animation?

  - by mahes25

  In the recent iOS 4.2 update, Apple introduced a nice animation for creating one level directories. I am trying to figure out how to implement a similar animation in my project. I would deeply appreciate it if anyone could give me any pointers to do this efficiently. From my investigation, I believe this animation or effect could be done very efficiently using Core Image which would allow me to write a custom filter. Unfortunately, Core Image is not available in iPhone. So how can do it? I read a blog post that explained a core animation scheme to create an iPad flip clock. The problem I have is similar but has important differences. Besides, I not excited about saving the subimage combinations, which I believe can cause a memory issue. Please enlighten me on the possible ways of doing this animation. I am relatively new to iOS programming, so I might have missed obvious ways of doing this animation or effect.

• Planning a skillset for a fallback career [closed]

  - by Davy Kavanagh

  I'm not too certain this is a SO question, but I didn't think it belonged in meta either. Long story short, I am bioinformatics researcher. I like to code, it's my favourite part of the job. I have been thinking for a while that if academia is not kind to me, I might seek a career in software development. My current contract is for three years and I would like to spend some time over the next 3 three years learning and practicing software development as possible. Python seems like a popular language and it what I mostly use to do things for me, but I am also in heavy use of R. So my main question is: Are python and R good things to be learning with a sotfware dev goal in mind, and if so, is there any particular type of programming or software that might be useful to have experience with. Hard questions to answer I know, but I thought I would get the answer from people who are in the know. Cheers, Davy.

• Operating System Widget Side Project

  - by Calpis

  I want to start on a side project and here's my idea: Whenever the user's mouse is pressed down, I want a small ring around the cursor to show up. I'm mainly doing this to learn more about programming and get myself to think outside of work related materials. My questions are: 1) is there a good source I can reference to start a project that deals with something like this? 2) Is visual studio a sufficient software to create such an application? Or would I need some other tool to do this. 3) What language should I choose to do this task? Thanks in advance!

• How to invoke static method in C#4.0 with dynamic type?

  - by Morgan Cheng

  In C#4.0, we have dynamic type, but how to invoke static method of dynamic type object? Below code will generate exception at run time. class Foo { public static int Sum(int x, int y) { return x + y; } } class Program { static void Main(string[] args) { dynamic d = new Foo(); Console.WriteLine(d.Sum(1, 3)); } } IMHO, dynamic is invented to bridge C# and other programming language. There is some other language (e.g. Java) allows to invoke static method through object instead of type. BTW, The introduction of C#4.0 is not so impressive compared to C#3.0.

• byte-sized bit pattern in C and its relevance?

  - by Nikunj Banka

  I a reading Kerninghan and Ritchie's C programming language book and on page 37 it mentions byte sized bit patterns like : '\013' for vertical tab . '\007' for bell character . My doubts : What is byte sized in it and and what's a bit pattern ? What relevance does this hold and where can I apply it ? Is it in any sense related to escape sequences ? I can't seem to find any information what so ever about these byte sized bit patterns on the web . please help . thanks .

• How do you invoke a web service from another web service using php?

  - by hello nottellingmyname

  So, I'm new to web programming, and for my homework I have to write some web services using PHP. Some of the web services have to use other web services, though, and we didn't learn how to do that. My professor said we should look up how to do that online. I think to call a web service using a GET parameter I just need to do file_get_contents(url), but I have no idea how to make a web service call using POST. So, how do I make a web service call from a web service using POST?

• Is there a c++ library that provides functionality to execute an external program and read its outpu

  - by BD at Rivenhill

  Basically, I'm looking for something that will allow me to replicate the following Perl code: my $fh = new FileHandle; $fh->open("foo |"); while (<$fh>) { # Do something with this line of data. } This is in the context of Linux, so a library that is specific to Windows will not help. I know how to write a program that does fork/exec/dup2 and all that basic shell-type jazz, but there are some fiddly details involving terminals that I don't feel like messing around with (and I don't have a copy of "Advanced Programming in the UNIX Environment" or a similar reference handy), so I'm hoping that someone has already solved this problem.

• What technology to use for a RIA

  - by user297159

  I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?

• What's the advantage for 'attach to process' compared with 'Start Debugging'?

  - by Nano HE

  Hi. I am new to programming. I know only Start debug before. Maybe start debug suit for some small application develop better. I found Visual studio IDE provide another method of attach to process for using. When & Why must I use the attach debugging? Such as multi-threading application debugging. Client/Service application debugging. etc. Thank you.

• Virtual directories as DB queries

  I have a site, e.g. site.com I would like users to be able to access it in their locale at site.com/somecity This is similar to craigslist, but they do it with subdomains e.g. sfbay.craigslist.org Using Apache HTTP server. MySql for DB. If you can provide a brief explanation and perhaps links to more thorough discussions, I would be quite interested in learning. I'm developing a web-app and wonder if I should focus some time to read up on Apache, or should I focus more of my time on server-side programming. Thanks!

• What exactly does "adopt a protocol" mean in the Objective-C / Cocoa documentation ?

  - by driis

  I am a C# developer getting started on Objective-C / Cocoa Touch programming. I think I might have gotten some terms wrong because I keep thinking about them "the C# way". Specifically, I have come around the term "protocol" in various documentation and tutorials. In Objective-C, what exactly is a protocol ? Can it be compared to a C# interface ? Is the following declaration the same as saying "The class is implementing the protocol UITextFieldDelegate" ? Or is UITextFieldDelegate to be compared with a generic type parameter in C# ? @interface MyViewController : UIViewController <UITextFieldDelegate> { }

• Grammatically correct double-noun identifiers, plural versions

  - by Michal Czardybon

  Consider compounds of two nouns, which in natural English would most often appear in the form "noun of noun", e.g. "direction of light", "output of a filter". When programming we usually write "LightDirection" and "FilterOutput". Now, I have a problem with plural nouns. There are two cases: 1) singular of plural e.g. "union of (two) sets", "intersection of (two) segments" Which is correct, SetUnion and SegmentIntersection or SetsUnion and SegmentsIntersection? 2) plural of plural There are two subcases: (a) Many elements, each having many related elements, e.g. "outputs of filters" (b) Many elements, each having single related element, e.g. "directions of vectors" Shell I use FilterOutputs and VectorDirections or FiltersOutputs and VectorsDirections? I suspect correct is the first version (FilterOutupts, VectorDirections), but I think it may lead to ambiguities, e.g. FilterOutputs - many outputs of a single filter or many outputs of many filters? LineSegmentProjections - projections of many segments or many projections of a single segment?

• Searching for a complex and well-designed PHP OOP application to learn from

  - by Raveren

  Basically, I am diving ever deeper into complex programming practices. I've almost no friends that are experienced (or more experienced than me) programmers to learn from, so I am looking for the next best thing - learning from the work of strangers. Can anyone recommend a real world finished and working application written well and OOP-centered. I'd like to take and analyze its source. Bonus if it's based on Zend Framework. What I am interested most in is objects that unlike desktop applications, have only one real operation done to them (or to their representation in DB or session) during their lifetime (or pageload), like user-logIn(). I'm interested in optimal and reusable design patterns and their real life implementations.

• Universal syntax file format?

  - by Isaiah

  Hey as a project to improve my programing skills I've begun programing a nice code editor in python to teach myself project management, version control, and gui programming. I was wanting to utilize syntax files made for other programs so I could have a large collection already. I was wondering if there was any kind of universal syntax file format much in the same sense as .odt files. I heard of one once in a forum, it had a website, but I can't remember it now. If not I may just try to use gedit syntax files or geany. thanks

• Claims-based Authentication: Are strings the essence of claims?

  - by Rising Star

  I've been programming with claims-based authentication for some time now with Windows Identity Foundation. It appears to me that in Windows Identity Foundation, once a user is logged in, the claims are basically strings of information that describe the user. With the old role-based authentication, I could say that a user is or is not a member of a given group, but with claims-based authentication, I can now have strings of information that describe a user. "This user is female". This user was born on "July 6, 1975". "This user logged in using a USB key". Is it the essence of claims-based authentication,that I have strings of information about the user given to the application by the framework?

• How can i convert between F# List and F# Tuple?

  - by ksharp

  Is there some way to convert between F# List and F# Tuple? For example: [1;2;3] -> (1,2,3) (1,2,3,4) -> [1;2;3;4] I need two Functions to do that: let listToTuple list = ... let tupleToList tuple = ... Thank you in advance. I think reflection is necessary to this problem. I know the performance is not good. I have to pay the cost of breaking functional programming rule.

• Does program need additional symbols from .so shared library except those declared in header file?

  - by solotim

  In C programming, I thought that a object file can be successfully linked with a .so file as long as the .so file offers all symbols which have been declared in the header file. Suppose I have foo.c, bar.h and two libraries libbar.so.1 and libbar.so.2. The implementation of libbar.so.1 and libbar.so.2 is totally different, but I think it's OK as long as they both offers functions declared in bar.h. I linked foo.o with libbar.so.1 and produced an executable: foo.bin. This executable worked when libbar.so.1 is in LD_LIBRARY_PATH.(of course a symbolic link is made as libbar.so) However, when I change the symbolic link to libbar.so.2, foo.bin could not run and complainted this: undefined symbol: _ZSt4cerr I found this symbol type is 'B' and it does not appear in libbar.so.2. Obviously this symbol has nothing to do with those functions I decared in bar.h. What's wrong here?

• How well does knowledge of J2ME generalize to other mobile platforms?

  - by dimatura

  I'm considering taking mobile phone software development course at my university. The course uses J2ME with an emulator. I'm interested in software development for mobile phones, but I get the impression that J2ME is somewhat stale and limited in comparison to the newer platforms like the iPhone and Android. I'm most interested in Android, as I dislike the closed nature of the iPhone. So if I take the course, how well would the skills acquired transfer to a platform like Android? And I have a related question. I'm pretty comfortable with Java (and various other programming languages), but I haven't used J2ME. Is there anything that makes it particularly painful to program with? (Not that Java is that pleasant anyway :))
