• Is it possible to use an input within a <label> field?

  - by javanix

  I have a bunch of optional "write-in" values for a survey I'm working on. These are basically a radio button with a textbox within the answer field - the idea being that you would toggle the button and write something into the box. What I'd like to do is have the radio button toggled whenever a user clicks in the text field - this seems like a use-case that makes a lot of sense. Doing this: <input type="radio" id="radiobutton"><label for="radiobutton">Other: <input type="text" id="radiobutton_other"></label> works fine in Chrome (and I am guessing, other WebKit browsers as well), but there are weird selection issues in Firefox, so I'm assuming its a non-standard practice that I should stay away from. Is there a way to replicate this functionality without using JavaScript? I have an onclick function that will work, but we're trying to make our site usable for people who might have NoScript-type stuff running.

• C# : What if a static method is called from multiple threads?

  - by Holli

  In my Application I have a static method that is called from multiple threads at the same time. Is there any danger of my data being mixed up? In my first attempt the method was not static and I was creating multiple instance of the class. In that case my data got mixed up somehow. I am not sure how this happens because it only happens sometimes. I am still debugging. But now the method is static on I have no problems so far. Maybe it's just luck. I don't know for sure.

• Winform not scrolling when drawing objects on it

  - by dezkev

  Hello All, C#3.0,.net framework 3.5 I am drawing ( using the draw method in the graphics class) a lot of solid rectangles on a windows form vertically. The form starts at 500 x 500 px and the rectangles are only drawn at runtime after data is downloaded from the net -and the number of rectangles depends on the download so I do not know it upfront. So only a few rectangles are drawn as the size of the form is fixed. So I googled/Binged ( lest someone suggest I do that) and found a few tips but they don't work in this case -like setting the forms AutoScroll property to true or trying double buffering.I also tried to draw on a listbox control and set it's scroll property etc...but no dice. I'm guessing there is no way to display , say 200 rectangles vertically on a windows form using draw. I need some other solution... any ideas please. Maybe a list of pictureboxes and then populate each picturebox with the solid color ? Thanks

• Atoms and references

  - by StackedCrooked

  According to the book Programming Clojure refs manage coordinated, synchronous changes to shared state and atoms manage uncoordinated, synchronous changes to shared state. If I understood correctly "coordinated" implies multiple changes are encapsulated as one atomic operation. If that is the case then it seems to me that coordination only requires using a dosync call. For example what is the difference between: (def i (atom 0)) (def j (atom 0)) (dosync (swap! i inc) (swap! j dec)) and: (def i (ref 0)) (def j (ref 0)) (dosync (alter i inc) (alter j dec))

• Parse and charset: why my script doesn't work

  - by Rebol Tutorial

  I want to extract attribute1 and attribute3 values only. I don't understand why charset doesn't seem to work in my case to "skip" any other attributes (attribute3 is not extracted as I would like): content: {<tag attribute1="valueattribute1" attribute2="valueattribute2" attribute3="valueattribute3"> </tag> <tag attribute2="valueattribute21" attribute1="valueattribute11" > </tag> } attribute1: [{attribute1="} copy valueattribute1 to {"} thru {"}] attribute3: [{attribute3="} copy valueattribute3 to {"} thru {"}] spacer: charset reduce [tab newline #" "] letter: complement spacer to-space: [some letter | end] attributes-rule: [(valueattribute1: none valueattribute3: none) [attribute1 | none] to-space [attribute3 | none] (print valueattribute1 print valueattribute3) | [attribute3 | none] to-space [attribute1 | none] (print valueattribute3 print valueattribute1 valueattribute1: none valueattribute3: none ) | none ] rule: [any [to {<tag } thru {<tag } attributes-rule {>} to {</tag>} thru {</tag>}] to end] parse content rule output is >> parse content rule valueattribute1 none == true >>

• How to always return a set number of records when using find_related_tags with acts-as-taggable-on

  - by hadees

  I'm using the acts-as-taggable-on gem and I need to use find_related_tags on my survey model to get back 3 surveys every time. In the event there aren't always 3 related I need to pick how ever many are related plus some random ones to get to 3. Additionally I have a method I wrote called completed_survey_ids which return an array of survey_ids that shouldn't be used because the user has already completed them. Also there is a rare case that there won't be enough surveys because the user has completed them all so in that event it is okay to return less surveys then requested. I did write a named_scope to handle getting rid of the completed_survey_ids that I think works named_scope :not, lambda { |survey_ids| {:conditions => "id NOT IN (#{survey_ids.join(',')})" } }

How to get the number from the score variable? Is there any easy way to let BeautifulSoup to return the value(in this case 524) itself?

• Is there a faster TList implementation ?

  - by dmauric.mp

  My application makes heavy use of TList, so I was wondering if there are any alternative implementations that are faster or optimized for particular use case. I know of RtlVCLOptimize.pas 2.77, which has optimized implementations of several TList methods. But I'd like to know if there is anything else out there. I also don't require it to be a TList descendant, I just need the TList functionality regardless of how it's implemented. It's entirely possible, given the rather basic functionality TList provides, that there is not much room for improvement, but would still like to verify that, hence this question.

• Simulating Ajax failures for QA testing

  - by womp

  Our first ASP.Net MVC/jQuery product is about to go to QA, and we're looking for a way for our QA guys to easily be able to simulate bad Ajax requests (without modifying the application code). A typical integration/UI test plan might be: Load page, click button "DoStuff" "DoStuff" fails Attempt button "DoStuff" again "DoStuff" succeeds Verify application state This is a simple test case - there will be cases with multiple failures and successes interspersed. Aside from "unplug your network cable" I'm looking for an easy way for our guys to simulate intermittent bad server responses. I'm open to any ideas so I won't go into too many details about our application setup or dependencies. How have you handled this?

• Alternate User select interface in django admin to reduce page size on large site?

  - by David Eyk

  I have a Django-based site with roughly 300,000 User objects. Admin pages for objects with a ForeignKey field to User take a very long time to load as the resulting form is about 6MB in size. Of course, the resulting dropdown isn't particularly useful, either. Are there any off-the-shelf replacements for handling this case? I've been googling for a snippet or a blog entry, but haven't found anything yet. I'd like to have a smaller download size and a more usable interface.

• DataGridView and checkboxes re-selecting automatically

  - by SuperFurryToad

  I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required. However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time. I'm sure I'm probably missing something obvious here?

• Vim Editor is very smart?

  - by Narek

  I am programming in C++ or Java. So I want to use Vim editor, because it is very flexible. I have heard that I can configure the Vim editor to be able to go from object to the definition from function to the definition from class name to the definition Do we have any professional Vim-er that could tell me how exactly to configure Vim for that? Thanks in advance. P.S. In case readers will consider this question is not connected with programming, I would say that this is improving speed of programming. So it is a help to the programmer. So please don't close this question. EDIT: Also I would like to know how vim works with code completion and can vim hint the list of methods that are available for the certain object? If yes, then I would like to know how to configure these options too?

• Using different versions of jQuery on the same page

  - by nimcap

  Users of my service includes a JS in their pages that I provide. I am hosting the script they are including. My script does some manipulation on their content. I am sick of writing my own DOM manipulators/selectors and wasting hours for jobs that can be done with 1 line of code if I can use jQuery. Some of the users of my service already uses jQuery (or Prototype etc.) on their pages, so if I include jQuery there will be a conflict. Because there will be version differences, I don't want to use their jQuery selectors, methods either in case jQuery exists. Keeping in mind that I have no control over their pages, how can I include jQuery and avoid conflict?

• Substring extraction using bash shell scripting and awk

  - by rohanbk

  So, I have a file called 'dummy' which contains the string: "There is 100% packet loss at node 1". I also have a small script that I want to use to grab the percentage from this file. The script is below. result=`grep 'packet loss' dummy` | awk '{ first=match($0,"[0-9]+%") last=match($0," packet loss") s=substr($0,first,last-first) print s}' echo $result I want the value of $result to basically be 100% in this case. But for some reason, it just prints out a blank string. Can anyone help me?

• Returning a ReadOnlyCollection from a method with an IList return type

  - by devoured elysium

  Here I have the following bit of code: private IList<IState> _states = new List<IState>(); private ReadOnlyCollection<IState> _statesViewer; public IList<IState> States { get { return _statesViewer; } } Generally it is preferable to return interfaces than the concrete classes themselves, but in this case, shouldn't I set as the return type of the States property a ReadOnlyCollection? Any user of my library will think it is possible to anything you can do with an IList if I set it as so, and that means adding elements. That is not true and I'm definitely breaking the contract exposing it as an IList. Am I right with this view or there is something else I am missing here?

• C# dealing with invalid user input

  - by Zka

  Have a simple console app where user is asked for several values to input. Input is read via console.readline(). Ex Name: Fred //string Lastname: Ashcloud //string Age: 28 //int I would like to make sure that int and double types are entered and if the user enters garbage, lets him repeat the procedure. Example, if the user enters "28 years old" where age expects int the app will crash. What is the best way to check for these inputs? Right now I can only think of: while (!Int32.TryParse(text, out number)) { Console.WriteLine("Error write only numbers"); text = Console.ReadLine(); } Is there any other way to do this? try catch statements if one wants to give a more detailed feedback to the user? How in that case?

• immediate=true is set on a jsf command button but still seeing validation

  - by Zack Macomber

  I have the following command button set up in a facelet: <h:commandButton action="#{addressAction.deletePreviousAddress}" value="#{bundle['button.deleteAddress']}" styleClass="deg-form-button" immediate="true"> <f:setPropertyActionListener target="#{addressAction.addressActionForm.previousAddress}" value="#{address}"> </f:setPropertyActionListener> </h:commandButton> In AddressAction, the following code gets run to delete a previous address on the form: public Enum<NavigationConstants> deletePreviousAddress() { addressActionForm.getPreviousAddresses().remove(addressActionForm.getPreviousAddress()); return NavigationConstants.addresses; } Before I made the address input components "required=true", this code worked fine and removed the previous address from the jsf form successfully. Right now, I can't successfully delete a previous address because validation is occurring and stating that the input components need to be filled in on the previous address record on the form. How can I bypass this validation? I thought the "immediate=true" attribute on the command button would have accomplished it but that's not cutting it in my case...

• Implementing a multi-state planner

  - by MoominTroll

  I've been asked to develop a system wherein employees can mark on a form their availability on a given day of the week - for instance an employee could mark themselves as available on a given time on a given week, and unavailable on some other time. It looks a little like this: Currently this works by rendering checkboxes within the table, picking up click events in each cell and marking the checkbox and hence the cell appropriately. I'm using the JQuery "click n drag checkbox" plugin from here. However, I've been informed that there could well be more than two states for a given cell (for instance available, unavailable, available in a given circumstance), in which case binding to a checkboxes checked value isnt going to be a lot of help. I've never used javascript or asp.net before and am unsure as to the best way to approach this problem. Ideally I could stick a data structure behind each cell which I could update to a certain state and then get my cell colour by binding to this - however I'm at something as a loss as how to best achieve this.

• Should I always call Page.IsValid in ASP.NET WebForms C#?

  - by mkelley33

  I know to never trust user input, since undesirable input could be compromise the application's integrity in some way, be it accidental or intentional; however, is there a case for calling Page.IsValid even when no validation controls are on the page (again, I know its bad practice to be trusting user input by omitting validation)? Does Page.IsValid perform any other kinds of validation? I looked at MSDN, and the docs seem to suggest that Page.IsValid is only effective if there are validation controls on the page, or the Page.Validate method has been called. A friend of mine suggested that I always check Page.IsValid in the button click handlers every time even if there are no validation controls or explicit Page.Validate calls. Thanks for any advice!

  - by Dobiatowski

  Hi, yesterday i noticed that sometimes on my webpage shows up javascript errors. when i went to source code, i found that one of .js files was totaly replaced with a ton of porn links. i checked the ftp for this file, but there was just old javascript file without any changes. yet i go back to check source code via browser and indeed there was again original .js today i visited my webpage again and the problem repeated. first visit showed me ton of porn pages cached .js file was hacked but after clearing browser cache js go back to oryginal i checked all files on my ftp against my offilne version, but all files are without any change. in last few years i was attacked by xss few times but in every case it was easy to diagnose and fix. but now i spend 12h and didnt find infection. do you have any idea how to find it? the webpage is: http://robert.frk.pl

• Can I interpolate two HEX color values without converting them to RGB?

  - by navand

  I'm trying to make a Gradient Class for a Blackberry app. At first I thought about converting the HEX values to RGB and then interpolating them before converting the result back into HEX, but since I will be doing this for every pixel line of an area, and the calculations will be made by a mobile, I thought that maybe there's a more efficient way of doing it. Maybe involving those pesky bitwise operators which I know nothing of... or something. So, is there a way of interpolating without converting to RGB and back? If so, is it faster than the original way? In any case, can you help me make the most efficient color interpolation? Thank you in advance!

• Should XML be used server-side, and JSON client-side?

  - by Michel Carroll

  As a personal project, I'm making an AJAX chatroom application using XML as a server-side storage, and JSON for client-side processing. Here's how it works: AJAX Request gets sent to PHP using GET (chat messages/logins/logouts) PHP fetches/modifies the XML file on the server PHP encodes the XML into JSON, and sends back JSON response Javascript handles JSON information (chat messages/logins/logouts) I want to eventually make this a larger-scale chatroom application. Therefore, I want to make sure it's fast and efficient. Was this a bad design choice? In this case, is switching between XML and JSON ok, or is there a better way?

• resetting the image in an NSView

  - by Josan

  I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?
