• display classes of a namespace in visual studio (C#)

  - by ericyoung7001

  I am a Java programmer, and just starting to use Visual Studio to do C# programming. In Java IDE such as Eclipse, if I do not know the classname in a package, I can just type a dot (.) after a package name, then I will get a list of all the classes in that package in the IDE. How I can configure visual studio to do the similar thing, say, if I click a namespace name in a file (for example, using System), or add a dot after the namespace, all the classes in that namespace will be displayed somewhere in the IDE?

• Problem: connecting to drupal on hostgator without pointed domain.

  - by Kirk

  I need to connect to drupal on a website that I'm programming on a hostgator account. The website that I'm working on currently receives a lot of traffic, and I would like to make sure that it is fully functional before I launch the new website. The old website was programmed with .asp which hostgator doesn't support, and the old webhost doesn't support drupal or .php which are integral to the new web design. Drupal 6 has been freshly installed on my website, but when I try to login, it redirects me to http://gator83.hostgator.com/?q=node&destination=node instead of the drupal control panel. Is it possible to work around this? Thank you in advance.

• Javascript clarity of purpose

  - by JesDaw

  Javascript usage has gotten remarkably more sophisticated and powerful in the past five years. One aspect of this sort of functional programming I struggle with, esp with Javascript’s peculiarities, is how to make clear either through comments or code just what is happening. Often this sort of code takes a while to decipher, even if you understand the prototypal, first-class functional Javascript way. Any thoughts or techniques for making perfectly clear what your code does and how in Javascript? I've asked this question elsewhere, but haven't gotten much response.

• How do Ruby and Python implement their interactive consoles?

  - by sxa

  When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share" the code? How is the code entered handled? Example: >> def x: >> print("Blah") >> >> x() Where is the function stored so it can be called at any time again? How can the interactive console take everything entered as obviously one program without executing everything over and over again?

• Creating a program to find longest path

  - by stef89

  Hi everyone, I'm fairly new to programming and I'm having a few problems. Basically I have to make a function that will find the lengths of all the paths through a network diagram. I've been working on this for hours but I can't seem to get anywhere. Using recursion I can navigate through every path but I'm just unsure as to how I should record the lengths of the paths. Any help would be greatly appreciated. Thanks! $dependencies = array("","","","1","3","4,2"); $durations = array("5","3","4","11","9","10"); function tracePath($path,$dependencies,$durations,$returnArray=array()) { if($dependencies[$path] != "") { $currentTaskDependencies = preg_split("/[\s]*[,][\s]*/", $dependencies[$path]); for($i=0;$i<count($currentTaskDependencies);$i++) { tracePath($currentTaskDependencies[$i]-1,$dependencies,$durations,$returnArray[$i]); } } return $returnArray; } tracePath(6,$dependencies,$durations);

• Is there a Chrome extension to add mailto links to email addresses?

  - by Martin Burch

  Wait, wait, this is a programming question! I want to build an extension if none exists. Imagine this: you come across a webpage that says "Just send a message to [email protected]" but to actually send the email, you need to highlight the address and then cut and paste it into the recipient field of a new compose window of your email client of choice. Obviously life would be easier if it were simply a mailto: link, so you could click on it and have a new message created automatically. (Or if the page designer had used a form, perhaps ...) I was originally going to ask if there was an extension to enable similar functionality for unlinked twitter @username mentions but I thought this email address problem would be a simpler situation. If you think it would be useless, perhaps I should look at the twitter username problem instead. Thanks for your feedback.

• How can I maximally partition a set?

  - by Gregory Higley

  I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

• How to set background image in Java?

  - by Dew

  I am developing a simple platform game using Java using BlueJ as the IDE. Right now I have player/enemy sprites, platforms and other items in the game drawn using polygons and simple shapes. Eventually I hope to replace them with actual images. For now I would like to know what is the simplest solution to setting an image (either URL or from local source) as the 'background' of my game window/canvas? I would appreciate it if it isn't something long or complex as my programming skills aren't very good and I want to keep my program as simple as possible. Kindly provide example codes with comments to elaborate on their function, and also if it's in its own class, how to call on relevant methods used by it on other classes. Thank you very much.

• Design pattern for extending Android's activities?

  - by Carl

  While programming on Android, I end up writing a parent activity which is extended by several others. A bit like ListActivity. My parent activity extends Activity. if I intend to use a Map or a List, I can't use my parent activity as superclass - the child activity can only extend one activity obviously. As such I end up writing my parent activities with the same logic for Activity, ListActivity, MapActivity and so forth. What am I looking for is some sort of trait functionality/design pattern which would help in this case. Any suggestions?

• c arrays: setting size dynamically?

  - by user336994

  Hello, I am new to C programming. I am trying to set the size of the array using a variable but I am getting an error: Storage size of 'array' isn't constant !! 01 int bound = bound*4; 02 static GLubyte vertsArray[bound]; I have noticed that when I replace bounds (within the brackets on line 02) with the number say '20', the program would run with no problems. But I am trying to set the size of the array dynamically ... Any ideas why I am getting this error ? thanks much,

• For what programs are Objective C and Ruby ideal on the Mac?

  - by Kurt

  Hi, as a Mac outsider it seems that two popular programming languages on the Mac appear to be Objective C and Ruby. From what I understand the main API Cocoa seems to be written in and optimized for Objective C, but it is also possible to use Ruby for that. Are there different areas where each language is ideal, for example, I could imagine Objective C could be ideal for a GUI layer, or standalone desktop app, and Ruby could be good for web services etc. What about classic business logic, or data access layers? What language would be a good choice for a library of services for example? Can we write a library in one language and link to it from a main program written in the other language? If I wanted to write a layered enterprise application using domain driven design and dependency injection which languages could support each concerns? Are things like DDD and DI common amongst Mac devs? Just a curious outsider.

• VB.NET: Force user to use the topmost form

  - by SiliconCelery

  I'm programming a Minesweeper clone in Visual Studio 2010, with VB.NET, as a Windows Form Application, and I'm having trouble with the Game Won and Game Lost forms. When I show those forms, I want the game form to still be visible, so that the player can see where the mines were, but I don't want the game form to be enabled until the Game Won or Game Lost form is closed. Exactly like Windows Minesweeper does when you win or lose. There aren't any obvious properties for this, as far as I can see, and I've had no luck Googling, I don't know what terms to search. Any help is appreciated, thanks.

• How to call/execute another ASP.net page from the parent ASP.Net page without disrupting the flow of

  - by NJTechGuy

  When a button/link is clicked, I want this URL to be called followed by the execution of the following statements. The ASP.Net page is in C# btw. Function A statement A call abc.apsx statement B abc.aspx is a silent page, doesn't display anything on the page but creates an output.txt file. So when abc.aspx is called, output.txt file is created and Statement B is executed seamlessly. Hope I made sense. I have no .Net programming knowledge. Please help me. Thank you..

• How does one search/poll all modal info in a frame automatically?

  - by user310631

  As you'll no-doubt be able to tell momentarily, I have little knowledge of the programming world. That being said, here goes.... In this scenario, there's a Java-based game that has a map of the game world oriented in an X, Y coordinate tile system. Some of the grid tiles are player cities, some are non-player locations. The game runs inside a frame in the browser, the X, Y coordinate map feature is one optional view, and the entire map is not available to view at any one time. Each grid tile has an "Onclick" event and an "Onmouseover" event. The mouseover event is a tooltip, the click event is something called a "modal" that has information specific to that tile. What I'd like to find out is: How can I poll all the grid tiles' "modal" information using some kind of script or other auto-running polling feature?

• Confusing Perl code

  - by titaniumdecoy

  I don't understand the last line of this function from Programming Perl 3e. Here's how you might write a function that does a kind of set intersection by returning a list of keys occurring in all the hashes passed to it: @common = inter( \%foo, \%bar, \%joe ); sub inter { my %seen; for my $href (@_) { while (my $k = each %$href) { $seen{$k}++; } } return grep { $seen{$_} == @_ } keys %seen; } I understand that %seen is a hash which maps each key to the number of times it was encountered in any of the hashes provided to the function.

• Default.png images and iPad.

  - by Leg10n

  I'm about to submit my first iPad app, and I have 2 questions regarding to Default.png images. I would prefer a "splash screen" showing some artwork of my app, instead of the UI as if it was loaded, the app is a bit heavy and I've seen the users dispair when the UI is apparently loaded but it's not working. Does anyone know if apple is accepting apps with "splash screens"? I want to provide a Default-X.png for every orientation, I've read the iPad programming guide, my question is, is "Default-LandscapeLeft" a Default image rotated 90 degrees clockwise, and "Default-LandscapeRight" rotated 90 degrees counter clockwise? I'm asking this because I don't have an iPad yet to test this on. Thank you a lot in advance.

• controlling bluetooth connection in matlab

  - by Mehreen Shahid

  we have a project in which we have to pick randomly generated numbers from a remote device, say mobile. there is a simple java application to generate numbers. next, we have to recieve those numbers in our matlab program via bluetooth connection with the device. assuming those numbers are temperature readings, we want to recieve a new number after every 10 sec and display the number on our matlab GUI program. the problem is do we implement bluetooth protocol through our programming? or use the matlab templates? because otherwise whenever we want to transfer file from a mobile to computer, we have to manually click "recieve a file" in blutooth wizard , just like we normally do to transfer a file. we want to enable the connection once, and then recieve text files after every 10 seconds to be read in our matlab program. can anyone please tell is it even possible in matlab? if yes, how do we establish such an automatic real time connection?

• MD5 hash differences between Python and other file hashers

  - by Sam

  I have been doing a bit of programming in Python (still a n00b at it) and came across something odd. I made a small program to find the MD5 hash of a filename passed to it on the command line. I used a function I found here on SO. When I ran it against a file, I got a hash "58a...113". But when I ran Microsoft's FCIV or the md5sum.py in \Python26\Tools\Scripts\, I get a different hash, "591...ae6". The actual hashing part of the md5sum.py in Scripts is m = md5.new() while 1: data = fp.read(bufsize) if not data: break m.update(data) out.write('%s %s\n' % (m.hexdigest(), filename)) This looks functionally identical to the code in the function given in the other answer... What am I missing? (This is my first time posting to stackoverflow, please let me know if I am doing it wrong.)

• Bash variable kills script execution

  - by Kyle Terry

  Sorry if this is better suited at serverfault, but I think it learns more towards the programming side of things. I have some code that's going into /etc/rc.local to detect what type of touch screen monitor is plugged in and changes out the xorg.conf before launching X. Here is a small snippet: CURRENT_MONITOR=`ls /dev/usb | grep 'egalax_touch\|quanta_touch'` case $CURRENT_MONITOR in '') CURRENT_MONITOR='none' ;; esac If one of those two touch screens is plugged in, it works just fine. If any other monitor is plugged in, it stops at the "CURRENT_MONITOR=ls /dev/usb | grep 'egalax_touch\|quanta_touch'." For testing I touched two files. One before creating CURRENT_MONITOR and one after CURRENT_MONITOR and only file touched before is created. I'm not a bash programmer so this might be something very obvious.

• Learning Objective-C 2.0 and ASP.NET 4.0 simultaneously?

  - by Sahat

  (HOBBY) I own a Macbook Pro and iPod Touch so developing iPhone/iPod/iPad apps seems like a logical thing to do in order to get some experience in the programming field. Besides I want to write a new application similar to the Capsuleer (Character skills monitor app for EVE Online MMO) but with more features. It's something I'd love to have on my own iPod Touch and I am sure other people will welcome a new EVE Online app for their iPhone or iPod Touch. (CAREER) I want to learn ASP.NET (and possibly Silverlight later on) for my potential future job. I plan to work in the .NET field, so it's a good idea for me to start learning C# and ASP.NET ASAP. Is it a good idea to learn completely unrelated technologies at the same time? Or would it be better to learn one thing at a time? Objective-C first, and ASP.NET second. Or vice versa. Thanks, Sahat

• How to write applications that modifies the Windows UI?

  - by StevenGilligan

  Hi, I have this programming question that's been bothering me for some time now. I'm wondering how is it possible to write applications that change the Windows UI? More precisely how could you write an application that modifies the Windows Taskbar or the Windows Desktop? I'm really interested in this topic but cannot find a lot of information. I've read about extending the Windows Shell but I can't seem to find anything related to modifying the Taskbar and the Desktop. I'm looking for something along the lines of Rainmeter. How did those guys create an application that lives inside the Windows Desktop? I'd like to point out that my prefered language for this would be C# but if you want to give me hints in other languages I'm fine with it and I am running on Windows 7. Thank you

• New to javascript, why is jQuery such a beast?

  - by gnucom

  Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

• VB6 Parser/Lexer/Scripter

  - by rlb.usa

  I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them. I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before. My question is: Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?

• What should I do to practice?

  - by simion

  I start a year long industrial placement in September where i will be coding in Java predominantly. I am going to use the summer to brush up on my Java as in year one of the degree Java was the main language taught for OOP modules. However this year i have had no Java exposure except for an algorithms module, which was one of eight, so as you can see i am probably getting really rusty!. What i wanted to know is, how does the "real world" java programming differ from university coding and what do you suggest i brush up on that would be different to my normal workings. As a start I definitely need to get familiar with a professional IDE like NetBeans, opposed to having used BlueJ throughout but more specifically what coding practices should I get more familiar with. I appreciate they wont expect me to be a qualified full developer and will give me time, but I would like to hit the ground running as it were, with me having full hopes to secure a permanent position after I finish my degree.
