  • Turbo C++ to Visual Studio 2010 migration [closed]

    - by BigGenius
    OK, based on my previous questions and your help., I have gone to install Visual Studio Express. But now problem is, the programs which I successfully code at home on Visual Studio don't run on Turbo C++ compiler at school (assuming I type the program instead of exporting code). Is there anything I can do? Also I am just learning basic syntax and data handling, loops, structures, arrays and all. But Visual Studio has auto completion and pretty typing (which may be advantageous) but crap for a beginner getting hold on to language. Sorry, if I have been unclear. But what should I do? This will make me lazy programmer and will reflect in my grades. Is there any other IDE, which I can use, very similar to Turbo C++ and able to run in Windows 7 in fullsreen mode.

  • Exclude complete namespace from FxCop code analysis?

    - by hangy
    Is it possible to exclude a complete namespace from all FxCop analysis while still analyzing the rest of the assembly using the SuppressMessageAttribute? In my current case, I have a bunch of classes generated by LINQ to SQL which cause a lot of FxCop issues, and obviously, I will not modify all of those to match FxCop standards, as a lot of those modifications would be gone if I re-generated the classes. I know that FxCop has a project option to suppress analysis on generated code, but it does not seem to recognize the entity and context classes created by LINQ 2 SQL as generated code.

  • 'Other' Features in a programming language

    - by user12960
    Online (i cant remember where) i saw someone mention he wishes programming language has more built in features for tools like documentation and source control. Now i dont understand what needs to be built in for source control since tools like git (sorry but i dont have much experience with others) has everything i need and is very easy to use. Documentation i can understand, perhaps the ability to generate remote procedures calls from source to some kind of IDL would be cool. But really i dont understand what features a programming language can/should have that isnt tied with code generation and syntax (except the two i mention when it comes to libraries). What ideas do you guys have? What is your wishlist?

  • Fluent NHibernate Self Referencing Many To Many

    - by Jeremy
    I have an entity called Books that can have a list of more books called RelatedBooks. The abbreviated Book entity looks something likes this: public class Book { public virtual long Id { get; private set; } public virtual IList<Book> RelatedBooks { get; set; } } Here is what the mapping looks like for this relationship HasManyToMany(x => x.RelatedBooks) .ParentKeyColumn("BookId") .ChildKeyColumn("RelatedBookId") .Table("RelatedBooks") .Cascade.SaveUpdate(); Here is a sample of the data that is then generated in the RelatedBooks table: BookId RelatedBookId 1 2 1 3 The problem happens when I Try to delete a book. If I delete the book that has an ID of 1, everything works ok and the RelatedBooks table has the two corresponding records removed. However if I try to delete the book with an ID of 3, I get the error "The DELETE statement conflicted with the REFERENCE constraint "FK5B54405174BAB605". The conflict occurred in database "Test", table "dbo.RelatedBooks", column 'RelatedBookId'". Basically what is happening is the Book cannot be deleted because the record in the RelatedBooks table that has a RelatedBookId of 3 is never deleted. How do I get that record to be deleted when I delete a book? EDIT After changing the Cascade from SaveUpdate() to All(), the same problem still exists if I try to delete the Book with an ID of 3. Also with Cascade set to All(), if delete the Book with and ID of 1, then all 3 books (ID's: 1, 2 and 3) are deleted so that won't work either. Looking at the SQL that is executed when the Book.Delete() method is called when I delete the Book with an ID of 3, it looks like the SELECT statement is looking at the wrong column (which I assume means that the SQL DELETE statment would make the same mistake, therefore never removing that record). Here is the SQL for the RelatedBook SELECT relatedboo0_.BookId as BookId3_ , relatedboo0_.RelatedBookId as RelatedB2_3_ , book1_.Id as Id14_0_ FROM RelatedBooks relatedboo0_ left outer join [Book] book1_ on relatedboo0_.RelatedBookId=book1_.Id WHERE relatedboo0_.BookId=3 The WHERE statment should look something like this for thie particular case: WHERE relatedboo0_.RelatedBookId = 3 SOLUTION Here is what I had to do to get it working for all cases Mapping: HasManyToMany(x => x.RelatedBooks) .ParentKeyColumn("BookId") .ChildKeyColumn("RelatedBookId") .Table("RelatedBooks"); Code: var book = currentSession.Get<Book>(bookId); if (book != null) { //Remove all of the Related Books book.RelatedBooks.Clear(); //Get all other books that have this book as a related book var booksWithRelated = currentSession.CreateCriteria<Book>() .CreateAlias("RelatedBooks", "br") .Add(Restrictions.Eq("br.Id", book.Id)) .List<Book>(); //Remove this book as a Related Book for all other Books foreach (var tempBook in booksWithRelated) { tempBook.RelatedBooks.Remove(book); tempBook.Save(); } //Delete the book book.Delete(); }

  • Managing a difficult manager

    - by griegs
    I have a situation here at work. We are redeveloping our basic architecture across the entire company. Currently we have the following hierarchy; SQL Database <= Stored Procs not allowed. nHibernate Classes to convert nHibernate into our own objects Web Service <= for all external and [internal] calls. Class to take objects from Web Service and back into our own objects and then… Normal nTier application architecture such as Data Transformation Layer, Business layer etc. Within the database, when we are writing a hierarchy of objects to the database, say for example; Order Person Details Address Product Other We need to serialise the object and save it, in its entirety, to an image field in a table. No attempt has been made to store the objects in their own tables so that we can do useful stuff like report on it. This is an architecture that was implemented [way] before I started and as you can probably appreciate, is a complete nightmare not to mention slow as a wet weekend. We’re not even allowed to have stored procs within SQL server because in my boss’s last job they had a hundred or so and he had a problem identifying them all so therefore all stored procs are the devil. Now the same person that developed the above architecture has developed the new one. It came as no surprise that he’s essentially used the same framework only now it’s using DotNet 3.5 with interfaces and generics. We still have to go through web services, still need to serialise (everything), still not allowed to use stored procs etc. In fact, we’re only barely able to bang two rocks together here. He says to us that the framework is open for discussion but when you discuss it, unless you approve of his design, you are told flatly “No”. He simply won’t listen to any other suggestions. Even when you show him demo applications of his proposed architecture v’s yours and he can see the speed difference, he still won’t take that on board. So I guess my question is, and I know others have experienced the same things out there, how do I get through to someone like this? How do you convince someone to ditch Web Services for internal calls and applications? How do you demonstrate, and make it stick, that stored procs are a better way to go than ad-hoc sql statements? This is killing me. I don’t want to repeat the mistakes of the past and I certainly don’t want to write code that I know is going to be slow and cumbersome. Help!

  • unit testing variable state explicit tests in dynamically typed languages

    - by kris welsh
    I have heard that a desirable quality of unit tests is that they test for each scenario independently. I realised whilst writing tests today that when you compare a variable with another value in a statement like: assertEquals("foo", otherObject.stringFoo); You are really testing three things: The variable you are testing exists and is within scope. The variable you are testing is the expected type. The variable you are testing's value is what you expect it to be. Which to me raises the question of whether you should test for each of these implicitly so that a test fail would occur on the specific line that tests for that problem: assertTrue(stringFoo); assertTrue(stringFoo.typeOf() == "String"); assertEquals("foo", otherObject.stringFoo); For example if the variable was an integer instead of a string the test case failure would be on line 2 which would give you more feedback on what went wrong. Should you test for this kind of thing explicitly or am i overthinking this?

  • how to reuse subquery result in mysql

    - by chris
    I'm doing a statistic job like this: SUM |COND1 |COND2 |... -------------------------- 100 |80 | 70 |... The SUM result is calculated from multiple tables, and the CONDs are subset of that. I wrote a sql like this: select tmp1.id,sum,cond1,cond2 as count from ( select id, count(*) as sum from table_1 group by table1.id) tmp1 left join ( select id, count(*) as cond1 from table1 where condition1 group by table1.id) tmp2 on tmp1.id=tmp2.id left join ( select id, count(*) as cond2 from table1 where condition2 group by table1.id) tmp3 on tmp1.id=tmp3.id the problem is that this is very poor efficiency, it will be better if i could use the result of tmp1, but i don't know how to do that. update: simplified the sql, what i mean is how to reuse the first select result of table_1

    I have used Eclipse Helios 3.6.1 for Java development. I wanted to start C++ development in the same IDE so I installed Autotools Support For CDT, C/C++ Development Tools, C/C++ Library API Documentation Hover Help plugins.I have included #include "cocos2d.h" in my HelloWorldScene.h file now when writing the below statement cocos2d::CCSprite * ccSprite; I am not getting auto completion bar(template proposals) on writing like coco and pressing Ctrl + Space from my keyboard. What can be the problem?This might help you solve my problem. Please check here. This is what I got after clicking Right Click Project - Index - Search for Unresolved Index. But I have added all includes check here. I think this is causing problem in Content Assist. What should I do in this case? Inclusion seems proper.

  • Why does editor color scheme preference seem to vary by language?

    - by Carl Manaster
    I've spent most of my career in C++ and Java, and like most of my peers I have the editor configured to display dark (black with dark-colored syntax highlighting) on a white background. I spent a day this week with Rubyists, and they all seem to favor light text on a dark background. I've observed this before. Why is it? What cultural differences between the Java and Ruby communities explain it? Or is it as simple as these are the default settings for our respective editors?

  • how to create 2D collision detection

    - by Aidan Mueller
    I would like to know the best or most effective way to test for 2D collision. I also can do AABBs but when you have a line, for example, that is rotated 45º, and it is really long. it will be hitting things when it shouldn't. I might be able to go through the pixels to see if they are touching others, but that might be slow if I had a big picture. and it might add some complications if I had a movie clip made of several images. How do I check collision between two Images? How would I do circle to box? Please help : ) PS: I do know java so you can write with java syntax and then use a made up GL

  • sqlite on iphone can open db but not prepare statements

    - by jan
    I'm brand new to using sqlite so I may have missed something basic. I've created a database and copied it into my app's document's directory. I'm able to open it but when I make a call to sqlite3_prepare_v2 I receive SQLITE_ERROR, "SQL error or missing database". here's my code: sqlite3 *database; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { sqlite3_stmt *compiledStatement; NSString *sqlStatement = @"select * from dbname"; int result = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, nil); ... } the same sql statement works in the terminal. I've found this question in a few places either without answers or with solutions that don't fix my problem. I'm hoping someone here will be able to help. Thanks.

  • What are the drawbacks of Python?

    - by Rook
    Python seems all the rage these days, and not undeservingly - for it is truly a language with which one almost enjoys being given a new problem to solve. But, as a wise man once said (calling him a wise man only because I've no idea as to who actually said it; not sure whether he was that wise at all), to really know a language one does not only know its syntax, design, etc., advantages but also its drawbacks. No language is perfect, some are just better than others. So, what would be in your opinion, objective drawbacks of Python. Note: I'm not asking for a language comparison here (i.e. C# is better than Python because ... yadda yadda yadda) - more of an objective (to some level) opinion which language features are badly designed, whether, what are maybe some you're missing in it and so on. If must use another language as a comparison, but only to illustrate a point which would be hard to elaborate on otherwise (i.e. for ease of understanding)

  • 8 Ways to Tweak and Configure Sudo on Ubuntu

    - by Chris Hoffman
    Like most things on Linux, the sudo command is very configurable. You can have sudo run specific commands without asking for a password, restrict specific users to only approved commands, log commands run with sudo, and more. The sudo command’s behavior is controlled by the /etc/sudoers file on your system. This command must be edited with the visudo command, which performs syntax-checking to ensure you don’t accidentally break the file. HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • Are Language Comparisons Meaningful?

    - by Prasoon Saurav
    Dr Bjarne Stroustrup in his book D&E says Several reviewers asked me to compare C++ to other languages. This I have decided against doing. Thereby, I have reaffirmed a long-standing and strongly held view: "Language comparisons are rarely meaningful and even less often fair" . A good comparison of major programming languages requires more effort than most people are willing to spend, experience in a wide range of application areas, a rigid maintenance of a detached and impartial point of view, and a sense of fairness. I do not have the time, and as the designer of C++, my impartiality would never be fully credible. -- The Design and Evolution of C++(Bjarne Stroustrup) Do you people agree with his this statement "Language comparisons are rarely meaningful and even less often fair"? Personally I think that comparing a language X with Y makes sense because it gives many more reasons to love/despise X/Y :-P What do you people think?

  • Looking for an open source project in Python

    - by Roman Yankovsky
    I am looking for practical tasks to get experience with Python. Just reading the books and not doing any tasks in the language is not effective. I solved some problems on the Project Euler and TopCoder and it helped me to learn the syntax of the language better. But those tasks are hard algorithmically, but as a rule is quite simple from the point of view of programming. Now I'm looking for an interesting open source project in Python, participation in which will help me to better understand the OO-model of language. Although, this is my first step with Python, in general, I am an experienced programmer and I can be useful for a project. May be someone can suggest something?

  • Adding cards to a vector for computer card game

    - by Tucker Morgan
    I am writing a Card game that has a deck size of 30 cards, each one of them has to be a unique, or at least a another (new XXXX) statement in a .push_back function, into a vector. Right now my plan is to add them to a vector one at a time with four separate, depending on what deck type you choose, collections of thirty .push_back functions. If the collection of card is not up for customization, other than what one of the four suits you pick, is there a quicker way of doing this, seems kinda tedious, and something that someone would have found a better way of doing.

  • Web Developer interview questions

    - by Baba
    I read an article today that listed some basic questions about web development: Describe how POST data was submitted to a server by a browser. Explain a number of HTTP status codes (except maybe 404 and 500). Explain SOLID or name a design pattern. Explain ways to improve a page load speed or user experience. The author says "if you can’t answer the questions above there are a lot of people who wouldn’t think of you as a Senior Web Developer." My questions are: How relevant are these questions in respect to real life web programming and scalability? How true is that statement? In other words, do you consider this knowledge a requirement to be considered a Senior Web Developer? I was able to answer all the questions, too easily it seemed, so I'm wondering whether it is effective to use these or similar questions to screen developers rather than asking them to write sample code.
