• Creating a "Universities Attended" Profile field/block (Drupal)

  - by Frank0051

  Interesting question for everyone. So I have am thinking of adding a "university attended" field to the profile page of members in Drupal. I guess I am trying to figure out the best way to go about it. I was originally thinking of a text field, but than I thought you could get multiple instances of of university names, making it hard to sort people by school (ie. UF, University of Florida, Florida, U of F, etc). I then began to think about creating a drop down, but I wasn't quite sure where I could get a listing of all the schools. Perhaps I could find a database population that a site like LinkedIn or Facebook uses. Then I thought of what happens when someone has attended multiple schools, how would I account for that? So, I guess I wanted to pose the question of how would you go about adding a University(ies) attended field to profile pages if you had to design a site to do so?

• Get result from mysql orderd by IN clause

  - by SchlaWiener

  I have the following query SELECT * FROM invoice WHERE invoice_id IN (13, 15, 9, 27) My result is: invoice_id | invoice_number | ... ------------------------------------ 9 | 201006003 | 13 | 201006020 | 15 | 201006022 | 27 | 201006035 | which is the result set I want except that is ordered by the invoice_id (which is an autoincrement value). Now I want the result in the order I specified in my query (13, 15, ...). Is there a way to achive that? The background is that I have a DataTable bound to a DataGridView. The user can filter and sort the result but if he want's to print the result I don't use the DataTable for printing because it only contains the most important columns and instead I pull the whole records from the database and pass it to my printing control. I also tried to extend the existing DataTable with the missing results but that seems to slower than using the IN (...) query.

• PHPUnit test for error thrown with wrong argument type

  - by Spencer Mark

  I'm just starting with PHPUnit and am ok with all assert* methods, but can't figure out how to test for error thrown when the wrong argument is provided to the method - say hinted with array like so: public function(array $list) { } and then tested with null as argument. Could someone please provide an example of how to test for this sort of errors? I've checked quite a few posts on stackoverflow, but couldn't find the answer to this specific issue. Edit Ok - just to give you an idea of what I'm testing - here's the ArrayHelper::removeIfValueIsEmpty() method: public static function removeIfValueIsEmpty(array $array) { if (empty($array)) { return array(); } return array_filter($array, function($value) { return !Helper::isEmpty($value); }); } and now test: class ArrayHelperTest extends PHPUnit_Framework_TestCase { public function testRemoveIfValueIsEmpty() { $this->assertEmpty( \Cmd\Helper\ArrayHelper::removeIfValueIsEmpty(null), '\Cmd\Helper\ArrayHelper::removeIfValueIsEmpty method failed (checking with null as argument)' ); } } This throws an error: PHPUnit_Framework_Error : Argument 1 passed to Cmd\Helper\ArrayHelper::removeIfValueIsEmpty() must be of the type array, null given

• Design patter 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?

• Sorting 1 million 8-digit numbers in 1MB of RAM

  - by Favourite Chigozie Onwuemene

  I have a computer with 1M of RAM and no other local storage. I must use it to accept 1 million 8-digit decimal numbers over a TCP connection, sort them, and then send the sorted list out over another TCP connection. The list of numbers may contain duplicates, which I must not discard. The code will be placed in ROM, so I need not subtract the size of my code from the 1M. I already have code to drive the ethernet port and handle TCP/IP connections, and it requires 2k for its state data, including a 1k buffer via which the code will read and write data. Is there a solution to this problem?

• Trigger on database using a web application and a winform application

  - by Michael

  Hello all, Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how. Can anyone help me with this?

• How to open the command prompt and insert commands using Java?

  - by 404 Not Found

  There have been a few other questions on here sort of like this, but none seem to have any answers. Is it possible to open the command prompt (and I guess any other terminal for other systems), and execute commands in the newly opened window? Currently what I have is this: Runtime rt = Runtime.getRuntime(); rt.exec(new String[]{"cmd.exe","/c","start"}); I've tried adding the next command after the "start", I've tried running another rt.exec containing my command, but I can't find a way to make it work. If it matters, I'm trying to run a command similar to this: java -flag -flag -cp terminal-based-program.jar

• Parse file to hash in Ruby

  - by Taschetto

  I'm a ruby newcomer who's trying to read a text file (a Valgrind simulation output) like this: -------------------------------------------------------------------------------- Profile data file 'temp/gt_1024_2_16.out' -------------------------------------------------------------------------------- I1 cache: 1024 B, 16 B, 2-way associative D1 cache: 32768 B, 64 B, 8-way associative LL cache: 3145728 B, 64 B, 12-way associative Profiled target: bash run.sh Events recorded: Ir I1mr ILmr Dr D1mr DLmr Dw D1mw DLmw Events shown: Ir I1mr ILmr Dr D1mr DLmr Dw D1mw DLmw Event sort order: Ir I1mr ILmr Dr D1mr DLmr Dw D1mw DLmw Thresholds: 99 0 0 0 0 0 0 0 0 Include dirs: User annotated: Auto-annotation: off -------------------------------------------------------------------------------- Ir I1mr ILmr Dr D1mr DLmr Dw D1mw DLmw -------------------------------------------------------------------------------- 1,894,017 246,981 2,448 519,124 4,691 2,792 337,817 1,846 1,672 PROGRAM TOTALS // other data I want to extract the PROGRAM TOTALS table and put it into a hash. Something like... myHash = { :Ir => 1894017, :I1mr => 246981, ILmr => 2448, ..., DLmw => 1672 } What are the best options for doing this? Could the CSV classes help me out? Thanks a bunch.

• Why does schema.rb change (in the eyes of Git) when just running rake db:migrate?!

  - by erskingardner

  This is a little general I know, but it's been bugging the hell out of me. I've been working on lots of rails projects remotely with Git and every time I do a git pull and see that there is some sort of data change (migration, or schema.rb change) I do a rake db:migrate. These generally run fine and I can continue working. But if you do a git pull and then git status, your working directory is clean (obviously) then do a rake db:migrate (obviously when there are changes) and another git status and all the sudden your db/schema.rb has changed. I have been just doing a git checkout immediately to reset back to the latest committed version of the schema.rb file, but why should this be necessary?! What is rails doing? Updating a timestamp? I can't seem to figure out what the diff is but maybe I'm just missing something?

• Python: Best practice for including a version number in an app?

  - by Ben

  I have a PyQt application that reads and writes data files. I am including a 'version number' in each file written. This is a simple number similar to: 1.2 or something (major and minor versions). I am doing this so that I can change the format of these data files in future versions and then still correctly parse them simply by checking to see what the version is inside the file. My question is what is the best practice for keeping this number stored inside the app itself. I.e. do I just hard-code the app version number into the class that is responsible for reading and writing files? Or should I have some sort of object/variable stored at the top-level of the app and somehow access it from the class responsible for reading and writing these files. If the latter, how do I store it and how do I access it? Thanks.

• copying files from one windows server to another

  - by Saju Pillai

  I have to copy a file from a windows 2008 server to one or more windows 2008 servers. I have accounts on the target machines with enough privileges to let me use powershell remoting and use wmi. The remote machines do not run ftp, ssh or similar file transfer mechanisms. I am not allowed to install software or run new services on the target server. I can run services on the source server. The file copy action must be initiated from the source server. i.e. I cannot manually logon to the target machines and initiate the copy - though an automated way to do this is acceptable. Is it possible to use WMI or PowerShell Remoting to push or pull the file from the source to the target ? Is it possible to invoke some sort of built in http client or invoke the BITS service/agent on the remote servers to pull files from the source server ? Other suggestions please.

• I need to create a web service using .NET-- where should I start?

  - by j-t-s

  Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

• Using variables within Attributes in C#

  - by tehp

  We have some Well-Attributed DB code, like so: [Display(Name = "Phone Number")] public string Phone { get; set; } Since it is quite generic we'd like to use it again, but with a different string in the Name part of the attribute. Since it's an attribute it seems to want things to be const, so we tried: const string AddressType = "Student "; [Display(Name = AddressType + "Phone Number")] public string Phone { get; set; } This seems to work alright, except that having a const string means we can't overwrite it in any base classes, thereby removing the functionality that we originally were intending to add, and exposing my question: Is there a way to use some sort of variable inside of an attribute so that we can inherit and keep the attribute decorations?

• What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

  - by Richard

  I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?

• In Magento, how can I preview a page before saving it?

  - by jeremysawesome

  I am using the Magento ver. 1.4.0.1 Community Edition. The problem I am running into is that Magento only allows me to preview pages that I have already saved. This works fine if I am creating a new page - but what if I am editing a current page? I want to be sure that the changes I make look good on the site before saving them. Does anyone know of a way to preview a static cms page before saving the changes made? I'm open to using some sort of plugin if anyone knows of one. Thanks

• Is my way of doing threads in Android correct?

  - by Charlie

  Hi, I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread? Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop...I don't understand that one...

• Take input through Buttons in java

  - by stash211

  I understand that the title might not be descriptive enough, but I'm making a magic square game in Java and basically, I'm trying to replicate user input as found in the sudoku game here: http://www.websudoku.com/. What I have is a n x n grid of Buttons (not JButton) as the board and what I want the user to be able to do is when the user clicks on one of the buttons, similar to the game above, it allows the user to type in his guess in the button itself instead of popping up a dialog box with an input field of some sort. I don't know where to start, I am a beginner in Java (not very beginner, but my knowledge with the various Java APIs is very limited), so I'm trying to find out if this would be possible and if it is, how would I go about doing it? Thanks for any help.

• Getting the last element of a Postgres array, declaratively

  - by Wojciech Kaczmarek

  How to obtain the last element of the array in Postgres? I need to do it declaratively as I want to use it as a ORDER BY criteria. I wouldn't want to create a special PGSQL function for it, the less changes to the database the better in this case. In fact, what I want to do is to sort by the last word of a specific column containing multiple words. Changing the model is not an option here. In other words, I want to push Ruby's sort_by {|x| x.split[-1]} into the database level. I can split a value into array of words with Postgres string_to_array or regexp_split_to_array functions, then how to get its last element?

• Compiling C-dll for Python OR SWIG-module creation, how to continue ??

  - by ljuju

  I reference this file "kbdext.c" and its headerfile listed on http://www.docdroppers.org/wiki/index.php?title=Writing_Keyloggers (the listings are at the bottom). I've been trying to compile this into a dll for use in Python or Visual Basic, but have not succeeded. I'm not familiar with C or GCC to sort out the problems or do the dll compile correctly. (I also get an error about snprintf not being declared when doing a regular compile of all the files). What are the steps I should do to make all functions available for other languages and external apps? Or is it perhaps easier to use SWIG and make a python module, instead of compiling a DLL?

• PHP - Using strcpsn() to protect against SQL injection?

  - by MichaelMitchell

  I am making a sort of form validation system and I need to check the SQL database to see if the username is already there. So, my question, is it effective to use a little if statement like this to protect against an attack? if (strcspn($string, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=" == strlen($string)){ return true; } So essentially, if the string contains any of these characters, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=", then the length will not equal that of the original $string. I am just wondering if this is sufficient to protect, or if there is more that I must do. Thanks.

• Prism for Silverlight: How to maintain views in a specific order inside a region.

  - by ArielBH

  Hi I am creating sort of a "Navigation panel" (which is actually an ItemControl) for SL and using Regions to allow each module to add his link to the panel. Problem is that modules loading is inconsistent and thus order of links in the panel can change according to modules loading order. Restricting the modules order is out of the question. Other feasible option is the order the region's Views Collection that is binded to the ItemControl, the problem is that ViewCollection is very limited, so ordering it is pretty hard. Did I miss an option, do you have an idea? Thanks Ariel

• How can I locally debug file permission issues in Visual Studio?

  - by robertc

  I want to debug an ASP.Net website as it attempts to write a file to a directory. When actually deployed this file would possibly not be writeable by the worker process so an error would be thrown, this is not a problem as I just want to catch the error, inform the user and move on. Of course, if I'm debugging on my local machine then I'm an administrator and I have permission to write to the file, so I can't check that I've trapped the correct errors and I can't step through an see where it goes wrong if I haven't. Is there a standard approach to this sort of thing?

• best method for background uploader in Android

  - by Dr.Dredel

  Problem: I want to write a process that will allow a user to take photos with the device and for those photos to then be uploaded to some listener in the cloud. The user should not have to do anything to initiate the upload, a background listener would just watch the folder and as long as it finds files in it it would upload them and delete them. Two problems: 1) how to keep the program running in the background even after the user is no longer taking pictures (and if they reboot the device for it to wake up and finish the uploads, if any remain) 2) assuming the connection is spotty (as it always is) how to verify that a given image has completed its upload, and if not, to resubmit it. I don't need any code examples, I just would like opinions on the best strategy to get this implemented. I was going to use Apache commons and just do an upload to a PHP, but am not sure what sort of error checking exists to take into account a connection drop mid file. TIA.

• best method for creating a universal extention/plugin

  - by rashcroft44

  Hi, I'm looking to create an extension for the leading browsers (firefox, safari and ie). Its rather simple, and I'm looking for the most efficient way to go about this. I need to get the hostname of the current site the user is on, and if it matches a certain parameter(eg, mysite.org), I'll need to append to the link some extra data and refresh to the new link. What is the simplest way to go about this? (I don't want to go in the direction of a bookmarklet - since this would require the user to click. I'd like this to happen automatically) sort of something like this: if(window.location.hostname == 'mysite.org') { location.replace(document.location.href + '/&mystuff=xyz'); } Thanks!
