• JQuery Validation Plugin not working when used on page that includes another page via AJAX

  - by droidy

  We have a long page that contains a bunch of different form elements. One part of the form is called remotely via AJAX and is populated in an empty div. This is the part which JQuery Validation plugin is not working correctly on. We have class="required" on the elements on this page, but they do not show up as required. I'm guessing it's because the Validation plugin is looking for class="required" on our main page, and since the content from the AJAX page is put into the empty div behind the scenes, it's not detected the required fields. Any help is greatly appreciated.

• How do I correctly use generics?

  - by ninjasense

  I basically am making webrequests and recieving a JSON response. Depending on the request, I am parsing JSON request into objects I have created. The parsing is pretty much the same no matter what the object Im parsing into looks like. So I have a bunch of methods doing the same work only with different objects, I was wondering how I could accomplish this with generics? Here is an example public static ArrayList<Contact> parseContacts(String responseData) { ArrayList<Contact> Contacts = new ArrayList<Contact>(); try { JSONArray jsonContacts = new JSONArray(responseData); if (!jsonContacts.isNull(0)) { for (int i = 0; i < jsonContacts.length(); i++) { Contacts.add(new Contact(jsonContacts.getJSONObject(i))); } } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { } return Contacts; }

• How can I tell what files are currently open by a process (i.e. my app)?

  - by chaiguy

  I am using a Lucene.Net index and want to give the user an option to move the index, but am having trouble closing it down so the directory/contents can be moved (I keep getting access denied exceptions). I need to be able to have some more information so I can debug this problem, such as being able to tell what files are currently open, and as much information about each use as possible. Alternatively, is there any way to simply force close a bunch of files so they can be moved? This would make things a lot easier to solve.

• Using SmtpClient.Send to send ~500-2500 emails what way would be faster.

  - by jamone

  I'm needing to send around 500-2500 emails out at a time to internal email accounts. I'm wondering which was would be faster both for the mail server and for my client app. Should I send multiple emails with just different TO addresses, or just one with multiple BCC addresses? I tried testing this by sending a bunch to my own email and the multiple emails method work, but with the BCC and a single message I only get that single message in my inbox. Shouldn't I be getting as many copies as the number of times I put my address in the BCC line?

• Splitting a string with variable number of spaces VBA

  - by GVBA

  I have a file with a bunch of number in columns. These numbers are separated by variable number of spaces. I want to skip the first line and get all the other lines and separte each number on the line. Finally, I want to write each number on Excel. I've been able to get the lines and write them on Excel but I can't separate each number (I'm getting the whole line as one string). Does any body know how to split a string that has a variable number of spaces? Here is my code. Sub Test() r = 0 With New Scripting.FileSystemObject With .OpenTextFile("C:\Users\User\Desktop\File.tab", ForReading) If Not .AtEndOfStream Then .SkipLine Do Until .AtEndOfStream ActiveCell.Offset(r, 0) = Split(.ReadLine, vbCrLf) r = r + 1 Loop End With End With End Sub

• Is it really wrong to version documents using CouchDB's behaviour?

  - by Tomas Sedovic

  This is one of those "I know I shouldn't do this but it's oh so convenient." questions. Sorry about that. I plan to use CouchDB for storing a bunch of documents and keeping their entire revision history. CouchDB does the versioning automatically, but it is strongly discouraged for programmer's use: "You cannot rely on document revisions for any other purpose than concurrency control." From what I've found on the CouchDB wiki, the versions can get deleted either during compaction or during replication. As far as I can tell, Compaction must always be triggered manually and Replication occurs only when there's more than one database server. The question is: if I won't run compaction and will use only single database instance for my documents, can I just use CouchDB's document versioning and expect it to work? What other problems I might run into? E.g. does not running compaction hurt the performance or consume significantly more disk space (than if I did handle the versioning manually)?

• Store code line in a string?

  - by user1342164

  I need to store code in a string so that if a value is true, it is in the code line if not true its not in the code line. When I populate summarytextbox if consulting amount is "" then dont use this code if is does have an amount include the code. Is this possible? Other wise I would have to do a bunch if then statements. When I do the following below it cant convert to double. Dim ConsultingFee As String Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Session("ConsultingFeeAmount") = "" Then Else 'Store the following line in a string???? ConsultingFee = +Environment.NewLine + Session("ConsultingFee") + " Amount: " + Session("ConsultingFeeAmount") End If SummaryTextBox.Text = Session("TeachingHospital") + Environment.NewLine + Session("HospitalAddress") + Environment.NewLine + Session("HospitalCity") + Environment.NewLine + Session("HospitalState") + Environment.NewLine + Session("HospitalZip") + Environment.NewLine + Session("HospitalTIN") + ConsultingFee End Sub

• Import C + Makefile into a linux IDE?

  - by Jessica

  I have a project for Linux that i've been developing for some time. Basically it's a bunch of C and H files together with a directory structure and a Makefile. Every time I need to debug something it's so painful, I need to manually search for var. definitions, structs, etc. Is there any good IDE out there for Linux that will allow me to import those files into a "project" and that will provide code completion or at least an easy way to get my bearings in the source code? thanks!

• Is it kEatSpeed or kSpeedEat?

  - by bobobobo

  I have a bunch of related constants that are not identical. What's the better way to name them? way #1 kWalkSpeed kRunSpeed kEatSpeed kDrinkSpeed Or, way #2 kSpeedWalk kSpeedRun kSpeedEat kSpeedDrink If we evaluate these based on readability understandability not bug prone with subtle errors due to using wrong variable name I think way #1 wins readability, they tie for understandability, and way #2 wins for not bug prone. I'm not sure how often it happens to others, but when variable names like this get long, then its easy to write kSpeedEatingWhenInAHurry when you really meant kSpeedEatingWhenInHome, especially when using autocomplete. Any perspectives?

• Calculating percentiles in Excel with "buckets" data instead of the data list itself

  - by G B

  I have a bunch of data in Excel that I need to get certain percentile information from. The problem is that instead of having the data set made up of each value, I instead have info on the number of or "bucket" data. For example, imagine that my actual data set looks like this: 1,1,2,2,2,2,3,3,4,4,4 The data set that I have is this: Value No. of occurrences 1 2 2 4 3 2 4 3 Is there an easy way for me to calculate percentile information (as well as the median) without having to explode the summary data out to full data set? (Once I did that, I know that I could just use the Percentile(A1:A5, p) function) This is important because my data set is very large. If I exploded the data out, I would have hundreds of thousands of rows and I would have to do it for a couple of hundred data sets. Help!

• Why only the constant expression can be used as case expression in Switch statement?

  - by sinec

  Hi, what is bothering me is that I can't found an info regarding the question from the title. I found that assembly form the Switch-case statement is compiled into bunch of (MS VC 2008 compiler) cmp and je calls: 0041250C mov eax,dword ptr [i] 0041250F mov dword ptr [ebp-100h],eax 00412515 cmp dword ptr [ebp-100h],1 0041251C je wmain+52h (412532h) 0041251E cmp dword ptr [ebp-100h],2 00412525 je wmain+5Bh (41253Bh) 00412527 cmp dword ptr [ebp-100h],3 0041252E je wmain+64h (412544h) 00412530 jmp wmain+6Bh (41254Bh) where for above code will in case that if condition (i) is equal to 2, jump to address 41253Bh and do execution form there (at 41253Bh starts the code for 'case 2:' block) What I don't understand is why in case that,for instance, function is used as 'case expression', why first function couldn't be evaluated and then its result compared with the condition? Am I missing something? Thank you in advance

• Sinatra Set Settings (Ruby)

  - by JP

  Using Sinatra in Ruby you can set the server's settings by doing: set :myvariable, "MyValue" and then access it anywhere in templates etc with settings.myvariable. In my script I need to be able to re-set these variables falling back to a bunch of defaults. I figured the easiest way to do this would be to have a function that performs all the sets calling it at the start of the Sinatra server and when I need to make the alterations: class MyApp < Sinatra::Application helpers do def set_settings s = settings_from_yaml() set :myvariable, s['MyVariable'] || "default" end end # Here I would expect to be able to do: set_settings() # But the function isn't found! get '/my_path' do if things_go_right set_settings end end # Etc end As explained in the code above, the set_settings function isn't found, am I going about this the wrong way?

• YUI and/or jQuery for a new project?

  - by Hortitude

  If I am starting a new project how should I pick between using YUI 2, YUI 3 and jQuery? I know there are a bunch of questions/answers already about can you use them together, but I am trying to figure out what criteria I should be thinking about to make my decision. Are they overlapping? Is one better at GUI and the other better at internals? Do they play well together? My understanding from other questions is that they can live in different namespaces, so they can live together, but that doesn't necessarily mean that it is good to use both. Thanks!

• How to handle dynamic site localizations?

  - by James Simpson

  I've got a website that is currently all in english. It is an online game, so it has a bunch of different pages with static text, as well as a lot of content in a database. I am trying to expand more globally and am gearing up to release some localizations of the site. However, I'm not sure about the best way to go about setting this up so that it'll be the easiest for me to manage and the easiest for users to use as well. Should I be storing the translated texts in a database, or should this be done in a completely different way? If it matters at all, the site is written in PHP and uses MySQL.

• How do I generate (ActionSctipt) classes for a new project?

  - by Iain

  Whenever I start a new game, I make a whole bunch of classes that extend my base classes, so: com.blah.Game extends com.iainlobb.Game and has some setup code com.blah.Player extends com.iainlobb.Player, and has some setup code etc Now all I need is a way to generate these classes at the start of the project so I don't have to create each one manually. It will save me at least an hour of faffing around per game. So how do I do it? I normally use FlashDevelop but I also have FlexBuilder 3, or I'm happy to download whatever other software I need (PC). Thanks.

• How to get array keys in Javascript?

  - by DisgruntledGoat

  I have an array created with this code: var widthRange = new Array(); widthRange[46] = { sel:46, min:0, max:52 }; widthRange[66] = { sel:66, min:52, max:70 }; widthRange[90] = { sel:90, min:70, max:94 }; I want to get each of the values 46, 66, 90 in a loop. I tried for (var key in widthRange) but this gives me a whole bunch of extra properties (I assume they are functions on the object). I can't use a regular for loop since the values are not sequential.

• Is GOTO really as evil as we are led to believe?

  - by RoboShop

  I'm a young programmer, so all my working life I've been told GOTO is evil, don't use it, if you do, your first born son will die. Recently, I've realized that GOTO actually still exists in .NET and I was wondering, is GOTO really as bad as they say, or is it just because everyone says you shouldn't use it, so that's why you don't. I know GOTO can be used badly, but are there any legit situations where you may possibly use it. The only thing I can think of is maybe to use GOTO to break out of a bunch of nested loops. I reckon that might be better then having to "break" out of each of them but because GOTO is supposedly always bad, I would never use it and it would probably never pass a peer review. What are your views? Is GOTO always bad? Can it sometimes be good? Has anyone here actually been gutsy enough to use GOTO for a real life system?

• How do I hook into a game and write a script to manipulate it?

  - by Ethan

  Hey SO, I know this is a pretty open question but I was wondering how people go about writing scripts that will "play" a game, or manipulate it in some way. I had been thinking that I'd try to get a working AI to play a game for fun, but don't even really know where to start. Are there any good resources to learn this? What are good languages to use? Once I have the language, how do I get my script hooked into the game? I was thinking of just trying simple flash games, if that helps. Thanks a bunch!

• How can I use a prefix for the fields in my strongly typed View?

  - by deadtime

  Hi, I have an EditProfile action in my PersonController, that finds a Person object by ID and does return View(person). The EditProfile view has a bunch of fields that should be filled in with the information from the Person object. One of the fields is named "Person.FirstName", and is not filled in automatically when the View is rendered. However, if I rename the textbox to "FirstName", it gets filled in. My question is: How can I specify to the view that it should use the "Person" prefix when filling in the information from the Person object? The reason I want to do this is because of consistency - in some of my views I allow the user to edit more than one object at the same time, and use prefixes in order to bind these correctly.

• How do you handle options that can't be used together with OptionParser?

  - by Joel

  My Python script (for todo lists) is started from the command line like this: todo [options] <command> [command-options] Some options can not be used together, for example todo add --pos=3 --end "Ask Stackoverflow" would specify both the third position and the end of the list. Likewise todo list --brief --informative would confuse my program about being brief or informative. Since I want to have quite a powerful option control, cases like these will be a bunch, and new ones will surely arise in the future. If a users passes a bad combination of options, I want to give an informative message, preferably along with the usage help provided by optparse. Currently I handle this with an if-else statement that I find really ugly and poor. My dream is to have something like this in my code: parser.set_not_allowed(combination=["--pos", "--end"], message="--pos and --end can not be used together") and the OptionParser would use this when parsing the options. Since this doesn't exist as far as I know, I ask the SO community: How do you handle this?

• iPhone UIImage Display Controller

  - by Bill Shiff

  Hello, I would like to be able to display a UIImage from within my app and support a lot of the functionality available in the built-in Photos app (i.e., pinch-to-zoom, pan, etc). I don't really want to write a bunch of code that someone has already written, so I'm wondering if there is a library out there already that I could just import into my project. I'm aware of the Three20 project, but I don't want to import a huge library if I don't have to. Is anyone aware of an available library that's already out there for displaying UIImages? Or part of some open-source project that can be pulled out on its own? Thanks!

• How to determine files that are subjected to filter via gitattributes when filter is executed?

  - by rasjani

  I have bunch of ruby scripts in a git repository and it seems to be really hard to enforce people to write properly indented code. I also have a small ruby script that formats to code to specific standard and now i would like to run that as a a filter script so that junk wont get committed into repository. echo "*.rb filter=rubyfilter" > .gitattributes echo "[filter \"rubyfilter\"]" >> .git/config echo " clean = /home/rasjani/bin/rbeauty" >> .git/config echo " smudge = /home/rasjani/bin/rbeauty" >> .git/config does the dirty trick git side but the ruby script should then process the files affected: how / where do i look those up from ?
