  • SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); whats that L in the argument for?

    - by ashishsony
    Hi, ive been working on c++ on linux for the past 2 years,and switched to windows c++ programming recently. can anyone tell me what that L is there in the argument of the function: SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); and on viewing certain sample code in MSVS C++ i came across hundereds of typedefs like.. LPARAM// typedef LONG_PTR LPARAM... here LONG_PTR is again typedef as __w64 long WPARAM// typedef UINT_PTR WPARAM... so there is a lot of chained typedefs.. I never saw this much of typedef chaining on c++ programming on linux using gcc.. what i want to say is that it just creates more confusion in this way for windows application programming.. while ive seen application programming on linux using frameworks like Qt.. there such things are rarely used.. so is there specific purpose in typedefining again and again on MSVSC++?? for eg.. there are typdefs like typedef int BOOL; whats the use of this when normal bool is available already..?? there are hundred other cases ive come across where just to decide what data type to use becomes so difficult.. it becomes difficult to understand a pre written code in this fashion too.. Thanks.

  • What are the most interesting equivalences arising from the Curry-Howard Isomorphism?

    - by Tom
    I came upon the Curry-Howard Isomorphism relatively late in my programming life, and perhaps this contributes to my being utterly fascinated by it. It implies that for every programming concept there exists a precise analogue in formal logic, and vice versa. Here's an "obvious" list of such analogies, off the top of my head: program/definition | proof type/declaration | proposition inhabited type | theorem function | implication function argument | hypothesis/antecedent function result | conclusion/consequent function application | modus ponens recursion | induction identity function | tautology non-terminating function | absurdity tuple | conjunction (and) disjoint union | exclusive disjunction (xor) parametric polymorphism | universal quantification So, to my question: what are some of the more interesting/obscure implications of this isomorphism? I'm no logician so I'm sure I've only scratched the surface with this list. For example, here are some programming notions for which I'm unaware of pithy names in logic: currying | "((a & b) => c) iff (a => (b => c))" scope | "known theory + hypotheses" And here are some logical concepts which I haven't quite pinned down in programming terms: primitive type? | axiom set of valid programs? | theory ? | disjunction (or)

  • How can i be sure that professional programming is not for me ?

    - by user17766
    Hello everybody I love programming, developing projects for hobby and learning new concepts. I am getting harder too much in current job Despite learnt many thing well. I can even hardly understand assigned tasks. I am asking why i am getting harder to myself. It may not my fault? Our architecture doesn't spend enough time to explain complicated sides of project for us or i am not enough smart one for understand fastly. Our architecture also doesn't know what kind of hell he is creating ? Seeing 3 level generic types and 4-5 level generic inheritance in domain model objects hell makes me think so really. It looks abusing concepts more than reduce complexity. Thinking that he hasn't experienced before such a big project while he is getting confused in problems of the project. May i am not in right company ? May i am not good programmer ? May i am really stupid ? Become good in programming concepts is not enough to deal big project's complications so someone should to tell me that i have to still effort too much even i am good programmer for adopting myself to any big project ? Also i had another bad experiences from previous job but my professional experiences is almost few months but i spend 2 years for learning and coding for fun and i really can say that i have well skills on OOP, Design Patterns, coding standards and deep knowledge in language currently used. Sometimes i am thinking to leave programming professionally and work in any lame job while doing programming just for hobby. Waiting suggestions and insights

  • Is there a resource that explains the benefits of layered programming?

    - by P.Brian.Mackey
    Some developers I know favor what I would call a procedural programming style. I recognize that procedural programming has its uses, albeit not in the business application world of .NET programming. So let's say we have a winform application with a buttonclick event. The buttonclick handles everything from the UI configuration to the database call and data manipulation. So you end up with a method that is 100's of lines of code long. Outside the fact that this code can't be considered test-able for various reasons, this style of programming is fragile to change. I can talk bout OO, Anti-patterns, etc. The problem is that any distinct topic I can dream up requires a great deal of explanation to understand the potential benefits. Outside of finding a new job (lots of businesses program this way), how can I teach these kinds of developers how to write better code? Obviously we can't sit around a round table and discuss pro's and con's all day due to time constraints and real work that has to be done. Although, training and intense training is the only thing I can think of to fix these problems. Not to say I write perfect code, I most certainly do not. I do believe there are certain best practices that should be followed as a rule E.G. OO in the context of .NET. The most common excuse I hear is "we can't write code fast enough if we do it like that".

  • Can One Get a Solid Programming Foundation Without Going To College/University?

    - by Daniel
    First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

  • [LAZARUS] Access Remote SQL Server Database on WinCE programming

    - by Dels
    I'm programming using Lazarus (Freepascal IDE, Delphi Like), and i have a problem when i need to connect into a remote SQL Server database on the network. My question: Is there any way to connect to a remote SQLdb on Lazarus? What is required connector type for SQL Server 2005? Is there any ODBC driver available for Windows CE (Windows Mobile 5/6)? (If so, I could use TODBCConnection...) I already searched and asked on the Lazarus community forum but didn't get any response

  • Sourcecode for Paymentroll example in Robert C. Martin book

    - by bitbonk
    Throughout the book "Agile Principles, Patterns, and Practices in C#" by Robert C. Martin a small Paymentroll application is build. While most of the source code is printed in place, some classes are missing and some are incomplete. The book says on the firest page: The book includes many source code examples that are also available for download from the authors' Web site. Unfortunately this seems to be a lie. Unless either this is not the author's website (the book forgets to mention the authors website adress) or I am blind. Does anyone have the comlete source code for that book preferably in form of a Visual Studio project or knows where I can find it.

  • Has there ever been a great print version of Why’s Poignant Guide to Ruby?

    - by Paul D. Waite
    Although it’s probably meant to be experienced on the web, I’d love to read a great print version of Why’s Poignant Guide to Ruby. It’s liberally licensed, so I can run off a copy for myself. But I think a work like that deserves more. Full colour illustrations. Main text on the left-hand page, sidebars on the right. (Stick in a few cartoons, or a slice of onion, when there aren’t any sidebars.) A built-in MP3 player and headphones for the soundtrack, but made completely out of telephone wires. Whilst that might be wishing for too much, have you (ever) seen any decent print versions of the book available?

  • book "Programming Role Playing Games with DirectX 2nd edition" and newer DirectX api

    - by numerical25
    I got the book "Programming Role Playing Games with DirectX 2nd edition" and I notice there are things in the book that are now considered deprecated. There is a whole Section on DirectPlay. And as much as I would like to avoid this section, I am afraid it might screw up the entire engine he is trying to build. So I was just curious to know even though DirectPlay is considered deprecated by XNA, and directX10. Is it possible to use it still in DirectX 9 ??

  • Java EE technologies after learning SE?

    - by jlafay
    Ok so there are lots of nifty little technologies included in Java EE. When one learns SE, where should they go from there? I think what I'm looking for is more abstract/high level technologies that pertain to EE. I want to learn more and it seems to be difficult to find a book to transition into EE from SE. Where should I go from here?

  • How to speed up calculation of length of longest common substring?

    - by eSKay
    I have two very large strings and I am trying to find out their Longest Common Substring. One way is using suffix trees (supposed to have a very good complexity, though a complex implementation), and the another is the dynamic programming method (both are mentioned on the Wikipedia page linked above). Using dynamic programming The problem is that the dynamic programming method has a huge running time (complexity is O(n*m), where n and m are lengths of the two strings). What I want to know (before jumping to implement suffix trees): Is it possible to speed up the algorithm if I only want to know the length of the common substring (and not the common substring itself)?

  • Introduction to 3D Graphics Programming

    - by Jacob Relkin
    Hi everyone! I'm a self-taught programmer with absolutely nil 3D programming experience. A client of mine has related to me an idea for an iPhone app that requires OpenGL ES 2.0 for it's inherently complex 3D structure and animations. Where do I start on this ( albeit long ) journey toward OpenGL ES competence? I'm willing to put in a tremendous amount of time and effort into learning, and if i could please get some pointers to where I should start and what to expect, that would be awesome!
