• PHP to C# and Vice versa

  - by Daniel Sh.

  I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

• Test-driven Development: Writing tests for private / protected variables

  - by Chetan

  I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

• What lessons have you learned about using a wiki as a development tool?

  - by Vivek Kodira

  I'd asked a question a while back about ways to encourage my team to collaborate. The tool we use is a wiki. Since this is the first time we are using the wiki (formally and as a team), we are learning by committing mistakes. One of the lessons has been that a wiki isn't suitable for tracking activities. It is better to use a tool built for-the-job (will elaborate if necessary). Are there other such anti-patterns? What development tasks would you NOT recommend using a wiki for (even though it may seem suitable at first glance)? Edit: Making this a community-wiki since it is probably unlikely that there will be 'one' right answer.

• Self Executing jQuery Plugin?

  - by GnrlBzik

  I am working on expansion of my jQuery plug-in authoring knowledge, just playing around with my own ideas for learning benefits. So i was wondering how you guys tackle the need of plugin executing without any user specific input. So I have a need for plug-in that executes right away after document is ready, without any user's specific input just as long as doc is loaded, so the only way I see how to execute plug-in on it's own is to attach handler to ready listener that executes my function which I extended the jQuery with. And because this needs to be self enclosed, part of the code, I attach handler to event listener within the function. So how else could one tackle this? Any take at this is appreciated. Thank you in advance everyone.

• In MS Access is there a way to allow forms to update while maintaning Read Only

  - by Alex

  I have several forms linked tables via queries. The form pull data such as sales and ratios by selecting a product from the main's form's combo box. I am however having to issues: 1- I would ultimately prefer the combo box to be a free entry; however by just entering in the box and hitting enter (not a button called “enter on a screen” which would initiate recalcs, just normal enter), while it does bring the new information in sub-forms it also changes the information in the original table. If I make the table read only that it just doesn't allow the form to work by saying that the table is read only. 2- The same Read only issue occurs when another user with read only rights tries to use the database. I understand that ready only is functioning as intended, however I am wondering if there is way to make some functions work while disallowing the updating. I am unfortunately learning on the go, so go easy plz. Thank you

• Is there such a thing as a C# style extension method in C++ ?

  - by Gary Willoughby

  I'm currently learning C++ and i run into the simple problem of converting an int to a string. I've worked around it using: string IntToString(int Number) { stringstream Stream; Stream << Number; return Stream.str(); } but though it would be more elegant to use something like: int x = 5; string y = x.toString(); but how do i add the toString() method to a built in type? or am i missing something totally fundamental?

• How to make some simple GUI controls?

  - by daniels

  I need to make a DirectX or OpenGL app and i will need a custom GUI for that. I think a button, a input text box, a list box (that will need a scroll bar as there will be more items that can fit on the screen) and a slider control will be enough. I know about CeGUI framework but i just don't like it, way too many XML files for my taste. My question is where should i start in learning how to do this custom GUI controls, are there any tutorial available or any material that could get me started? I haven't done a GUI contol myself before.

• Compile C++ from VS08/10 without Run Time Library / MFC

  - by Lienau

  Are there settings I can adjust in Visual Studio so that it does not compile with any run time library or MFC. I started learning C++ to get away from C#'s .Net, and this is just as bad. When I execute the program in a Windows XP virtual machine I get an error. I can compile without the dependencies in Code::Blocks, but I'm more familiar with VS, and prefer many of it's features over those of Code::Blocks. If you know of to get past this, it would be greatly appreciated. Thanks.

• How to write syntax highlighting? c++

  - by ML

  Hi All, I am embarking on some learning and I want to write my own syntax highlighting for files in C++. Can anyone give me ideas on how to go about doing this? To me it seems that when a file is opened: 1. it would need to be parsed and decided what type of source file it is. Trusting the extension might not be full-proof a way to know what keywords/commands apply to what language a way to decide what color each keyword/command gets I want to do this on OS X, C++ or Objective-C Can anyone provide pointers on how I might get started with this?

• Using scanf() in C++ programs is faster than using cin ?

  - by zeroDivisible

  Hello, I don't know if this is true, but when I was reading FAQ on one of the problem providing sites, I found something, that poke my attention: Check your input/output methods. In C++, using cin and cout is too slow. Use these, and you will guarantee not being able to solve any problem with a decent amount of input or output. Use printf and scanf instead. Can someone please clarify this? Is really using scanf() in C++ programs faster than using cin something ? If yes, that is it a good practice to use it in C++ programs? I thought that it was C specific, though I am just learning C++...

• Pros and Cons of Proprietary Software

  - by Jon Purdy

  Proprietary software is about as good as open-source software. There are so many problems with proprietary technologies, however, that I'm beginning to think it's best to avoid them: The software will only be maintained as long as the company exists (and profits). The level of security of the application is as unknowable as the source code. Alterations and derivative works, however necessary and beneficial, are disallowed. I simply don't see any point in even learning to use such systems as those created by Microsoft and Apple. Of course I don't pretend that ignorance is the superior option: one has to have a certain working knowledge simply because of the ubiquity of these things. I just don't see any reason why, as an independent developer, I should ever consider it a remotely good idea to actually use them. So that's the question, or discussion topic, or what have you: In what ways do developers benefit at all from using closed-source development software?

• Difference between var and Class class in object creation

  - by Divine

  Its a silly question, however shocked to see different behaviors. Learning a lot. Lets say I have two classes below Class A { public void Display() { } } Class B : A { public void Display() { } } Class C : B { public void Display() { } } Class Final { static void Main() { var c = new C(); // B c = new C(); //My doubt is, both of the above gives different results. May I know B c = new C() creates object of B or C? What I understood is, it creates object of B. Then why we say "new C()"? I agree with C c = new C(); But I thought, B b = new C(); creates object of B. Where we use this style? Only when utilizing runtime polymorphism? (Overriding methods)? } }

• Using netbeans as IDE for Python

  - by morpheous

  I am about to embark on learning Python (largely for the purposes of using it as scripting glue between my applications). I use Netbeans (6.8) for both my C++ and PHP development work. Ideally, I would like to use the same IDE for Python - and there is a Python plugin for Netbeans (admittedly, its still in Beta). Does anyone have any experience using Python with Netbeans? Shall I use Netbeans (for the reasons stated above - i.e. already familiar environment), or is there a [GOOD] reason why I should use a different IDE?

  - by bino oetomo

  Dear All .. I'm learning to drive a stepper motor with Python. It's hard now to find a PC with paralel port.

• Sliding "pull-down" navigation - what do I use? How do I implement? jQuery?

  - by Josh Carey

  I'm new to Javascript and jQuery, but I'm learning. Here is what I'd like to accomplish: I have a row of navigation "pull-down" tabs that I'd like to animate. Some sliders will have text links to sub-pages and some will not. The bottom portion of the tab should be clickable to go to the main page. Then the sub-page, text links should also be clickable. Here is a graphic example that should make sense of what I'd like to do: http://lionheart.net/downloads/nav-example.png Mouse over, would slide it down. Mouse out, after a second, should auto-slide up. Is this possible with jQuery or something else? Thanks so much for any help you can give me!

• MVC, how view should be accessed from controller?

  - by Kirzilla

  Hello, I'm just learning MVC so you could find my question rather strange... My Controller have access to different shared objects through Container object passed to Controller's constructor. To access shared objects I should do $this-container-db to access Database adapter or $this-container-memcache to access Memcached adapter. I want to know should I put View object into Container with shared objects or no? From one side it is really comfortable to take view from this container, but this way I couldn't create multiple Views instances (for example, every time I'm calling Controller's method from View I should have one more View instance). What is the solution? How should I pass View object into Controller and/or how should I create new View instances from Controller? Thank you!

• 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.

• Create a javascript chome extention that does not execute in 6 months

  - by user1907657

  I have just started learning programming and I would like to make a script into a chrome extension. Its a basic script and I hope to practice more and more and develop bigger projects and set myself bigger tasks This script has to do the following : reload a page every 20 seconds (say google.com) after 6 months the script must not run (maybe prompt a window saying "its over 6 months") The code should be able to go into a small chrome extension and also the 6 month time period should be absolute not relative to the time the script was started; for example should the browser crash and i have to turn on the extension again it should not restart the 6 month counter. Also if anyone could recommend any good sources for JavaScript to learn (preferably books; nothingIi read online ever seems to stick)

• A way of allocating multidimensional arrays dynamically

  - by C77431

  salute.. I am learning dynamic allocations for multidimensional arrays in a book and I found some ways for that, And now haven't problem in it. But the author of the book shows us a way, but it doesn't work correctly. It is this: pbeans = new double [3][4]; // Allocate memory for a 3x4 array And this is the error: error C2440: '=' : cannot convert from 'int (*)[4]' to 'int *' how should i define pbeans ( if this type of coding is legal)? and what is the problem exactly? Regards.

• Good File Organization Suggestions for Developer

  - by Paul

  I am struggling a little with folder organization to organize the many projects that I work on. I work on OS X - right now I am using ~/Development/ as the root folder, and I have many types of projects. For example, I have my iPhone apps under ~/Development/Xcode I develop in many languages, from PHP, to Ruby, to Python, to Objective-C. So, for example, I might have a couple of open-source apps based on PHP where I am using the Zend framework. Some of these projects are for clients, others are tests/experiments when learning a new language or general experimenting. I am really interested in how other developers have organized code/projects and could pass along some advice to make it very easy to navigate through code/projects related to many languages and types of projects.

• Delphi developer switching to C#

  - by Dorin Duminica

  Hello, I'm a Delphiholic for quite some time now and lately I was thinking of learning some C# as well, however I'm kinda' "afraid of the unknown", I've done some simple apps as a test drive for C# and I have to admit that I've liked it, HOWEVER I do not really like the IDE... that being said here's the question that I would appreciate if others who went down this path would answer: As a Delphi developer what are the "main basic" changes from the Delphi language(by basic I mean basic -- utility functions, streams, etc.), I'm used to add "System, Classes, Windows" to uses not "use System.XXX.YYY.ZZZ", I'm trying to make a partial equality in my mind from Delphi to C# until I can see where does Delphi go hand-in-hand with C# and so on... I hope the question is pretty clear, if not, do not hesitate to swear me and I'll try to clarify as well as I can :-)

• TeamCity build triggers don't automatically run

  - by Phil.Wheeler

  I've been playing around with and learning a bit about TeamCity and have the server correctly set up with my .Net MVC project committed in Subversion successfully and build configurations and triggers sorted to kick off when any changes are committed to the repository. TeamCity polls on its default time period and is picking up that changes have been committed, but it is adding these to the queue without actually ever running them. I have to manually click the "Run" button to kick them off. What setting do I need to change in order to ensure that any new changes are automatically run?
