  • What are the list of Patterns and Principals the programmer must/should know?

    - by pang
    I have been doing code for a few years and still feeling that my knowledge still not broad enough to become a professional. I have studied some books related to Design Pattern but I know there are many others. So could anyone list the one which you think it is good to learn to become a better programmer and more professional? Programming Languages I work on : C# , Ruby, Javascript

  • How do I superimpose one bitmap image on another in GDI+?

    - by Old Man
    Using GDI+ I've made a heatmap bmp and I'd like to superimpose it on top of my bmp map. I've saved the two bmps to disk, and they look good, I just need a way to put them together. Is there any way to do this, perhaps using the Graphics object? How is transparency/alpa involved? I'm very new to GDI programming so please be as specific as possible.

  • How Do I Setup the Notepad++ Run Command for Ruby?

    - by EstanislaoStan
    I'm trying to setup the Notepad++ IDE so that when I press F6 the Ruby script I'm editing will run. After searching the internet I've found that putting [cmd /K ruby "$(FULL_CURRENT_PATH)"] without the brackets into the run dialogue box that pops up when I press F5 will run basic scripts in the Command Prompt (I'm using Windows 7). However, if my code loads any external data such as .txt files, or as I've found with Gosu, loads any image files, Ruby complains that things do not exist which do in fact exist. I know my code and Ruby installation (Ruby 1.9.3) are fine because prior to now I've been using FreeRIDE, an older, somewhat buggy IDE that I've grown tired of, and my code runs fine when I press F5 using that IDE. Some examples of the complaints follow.

  • void foo(int &x) -> Ruby? Passing integers by reference?

    - by Earlz
    Hello, as a way to spice up my C++ programming homework, I've decided to instead of typing the C++ from the book onto my computer, instead reforming it in Ruby. Yes it's a bit silly, but I'm bored. Anyway, I'm having trouble converting this kind of function to Ruby void swap(int &a,int &b){ int c=b; b=a; a=c } What would the equivalent ruby code looking inside a function ?

  • ASP.NET Free Online E-books or tutorials

    - by the_drow
    I need to learn programming ASP.NET with C# but I can't find a good online book to do so. Is there an ASP.NET equivalent to Diving into python? All of the books are quite expensive. I already know Java and C++, are there any major differences between them and C#? If so are there materials that cover only the differences and what I should learn?

  • Accessing the "super of this" in Java

    - by gerdemb
    This is what I'm doing now. Is there a better way to access the super class? public class SearchWidget { private void addWishlistButton() { final SearchWidget thisWidget = this; button.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { // A better way to access the super class? // something like "this.super" ...? workWithWidget(thisWidget); } } } } I'm programming with Google Web Toolkit, but I think this is really a generic Java question.

  • Where can I find a web-project "security checklist?"

    - by iaagty
    I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e., Cross Site Scripting Cross Site Request Forgery Sanitize form data that goes into database Disable register globals and error reporting in custom php.ini Upload files below web root ...(the list goes on) I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines. Thanks in advance.

  • Setting up separate ctags db's for C/C++ standard libs, boost, and third party libs

    - by Robert S. Barnes
    I want to set up separate ctags databases for various libraries in /usr/include/ for use with OmniCppComplete. The idea is to be able to pull in only the libraries needed for a particular project in the target language - C or C++. For example, I'd like to have one database for the standard C libraries, one for system libraries that might be used by either C or C++ programs ( sockets / networking comes to mind ) one for the standard C++ libs / STL / Boost, and then other databases for various third party libraries such as QT or glib. Then I could pull something in simply by typing set tags+= ~/.vim/somelib.tags in vim. I assume that everything related to the C++ stdlib and STL are in the /usr/include/c++ and that Boost is all in /usr/include/boost. Unfortunately it seems that the standard C libs and system libs are just kind of dumped directly into /usr/include/ with a variety of other stuff. How can I get a list of which files and directories belong to which libs? I'm on Ubuntu 8.04.

  • What potential do you see in Silverlight?

    - by Cyril Gupta
    Silverlight has been available since quite some time, and Silverlight 2 allows .Net programming on the front-end. I've been thinking about the apps that I can make using Silverlight, but I can't decide if I should go for development in Silverlight because i am still concerned about accessibility and acceptance. What potential do you see in Silverlight judging from the current trends, and what do you think Silverlight will be used for in the coming years?

  • Any application to bind documents of different kind

    - by Codeslayer
    A situation that may be quite common in offices is: We communicate with clients over e-mails, exchange documents and spreadsheets with them. Is there any tool which will help me in binding all these outputs. Maybe I may get flamed on this as this is not exactly a programming question. But some inputs may certainly help me. Thanx
