  • javascript "associative" array access

    - by cp
    Hello I have a simple simulated aarray with two elements: bowl["fruit"]="apple"; bowl["nuts"]="brazilian"; I can access the value with an event like this: onclick="testButton00_('fruit')">with `testButton00_` function testButton00_(key){ var t = bowl[key]; alert("testButton00_: value = "+t); } However whenever I try to access the aarray from within code with a key that is just a non-explicit string I get undefined. Do I have somehow have to pass the parameter with the escaped 'key'. Any ideas? tia.

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • How to use SQLiteOpenHelper without or less restrictive use of Context?

    - by Pentium10
    If you extend SQLiteOpenHelper, for the Constructor you have to use a Context. I am wondering if there is a way to leave this out, and be able to work with database tables without a Context. Or at least be least restrictive, I mean a way of project/class structure that will make history the several context passings I have to do now. As it is my application has several level of classes, chained in each other, and there are a few that connects to the database, but have no whatsoever influence on the interface, so they don't actually need the Context. Are you creating your classes in the way that you pass each time a Context to them? If not, how you do, how you reuse a Context in a short class?

  • Show a django relationship in a template

    - by kevin_82
    I have a django model as follows: class Person(models.Model): name = models.CharField(max_length=255) class Relationship(models.Model): parent = models.ForeignKey(Person) child = models.ForeignKey(Person) description = models.TextField(blank=True) In my view, I pass a certain person, and the relationships in which he/she is parent: person = Person.objects.filter(name ='some name') descendant_relationships = Relationship.objects.filter(parent = person) An I want to show this person's descendants in a list in a template: <ul> {% for item in descendant_relationships%} <li> {{item.child.name}} - {{item.description}} </li> {% endfor %} </ul> But this template code will not show the children of children (i.e. grandchildren, great-grandchildren etc.). How can I get these lower level descendants to show up? I imagine recursion is necessary somewhere, but where?

  • Commenting system for CakePHP blog tutorial

    - by Ryan
    I'm building off the CakePHP tutorial for the blog engine by adding comments to each post. I am able to add comments by selecting the post that it should be attached to, via a select box. I would like to be able to click an "Add Comment" link within the post and have the association to the post formed programatically. I am unsure how I can pass the post_id to the add method within my comments_controller. The body of my add method is the auto-generated scaffold code. Is it as easy as adding a $postId argument to the add method and write this to the post_id in my comments model? This doesn't feel right though, since I would expect add to be called when my submit button is click on my comments add view. Thanks all.

  • Django: do I need to do HttpResponseRedirect to render a simple string after a POST?

    - by AP257
    I've got a mobile app that makes POST requests to a Django site. I want to return a simple string (not a template-based page) after the app makes the POST request, saying 'Success' or 'Failure' as appropriate. However I know that after a POST request in Django you're supposed to do a HttpResponseRedirect. But, do I really need to redirect to another page and write a new function to handle it, all to output a string? And if so, how do I pass the success/failure status of the app in the HttpResponseRedirect, since it's only supposed to take one argument? Thanks!

  • passing parameters to a thread

    - by assassin
    I want to pass a function that takes a parameter to the ThreadStart Constructor in C#. But, it seems that this is not possible, as I get a syntax error it I try to do something like this Thread t1 = new Thread(new Thread Start(func1(obj1)); where obj1 is an object of type List<string> (say). If I want a thread to execute this function that takes in an object as a parameter, and I plan to create 2 such threads simultaneously with different parameter values what is the best method to achieve this?

  • getting HtmlTextWriter of a control

    - by lissa
    is it possible to get HtmlTextWriter of a control? if no, then how can i call the RenderEndTag of a control in code behind? i am facing a problem in my application. i extended the listbox user control and override its RenderEndTag event. if i used the new listbox (Mylistbox) normally inside a WebPage, everything works fine. but when i put Mylistbox in a Webusercontrol and include the Webusercontrol in a WebPage, the RenderEndTag of the control is not called for some reason. so i guessed that i should explicitly call 'RenderEndTag' of the control. to do so i need to pass an HtmlTextWriter...

  • Local variable not being passed to partial template by render?

    - by brad
    I don't seem to be able to pass a variable to my partial template in rails (2.3.5). My code is as follows; In the main view .html.erb file: <% f.fields_for :payments do |payment_form| %> <%= render 'payment', {:f => payment_form, :t => "test" } %> <% end %> and in the _payment.html.erb file: <%= t %> produces a wrong number of arguments (0 for 1) error. The payment_form object is being passed to the partial as f without any problems. I've tried a number of variations on the above syntax (e.g. :locals => {:f => payment_form, :t => "test" } without success. I presume I'm doing something pretty basic wrong but just can't see it.

  • What is the accepted way to replace java.util.Date(year,month,day)

    - by dagw
    I'm trying to do something really simple, but starting to realize that dates in Java are a bit of minefield. All I want is to get passed groups of three ints ( a year, a month and a date) create some Date objects, do some simple test on them (along the lines of as date A before date B and after January 1 1990), convert them to java.sql.Date objects and pass them off to the database via JDBC. All very simple and works fine using the java.util.Date(int year,int month,int day) constructor. Of course that constructor is depreciated, and I'd like to avoid using depreciated calls in new code I'm writing. However all the other options to solve this simple problem seem stupidly complicated. Is there really no simple way to do what I want without using depreciated constructors? I know the standard answer to all Java date related questions is "use joda time", but I really don't want to start pulling in third party libraries for such a seemingly trivial problem.

  • Referral System PHP

    - by Liam
    I have a membership based website and im planning on implementing a referral system. My website is credit based, the idea is that if User X refers User Y, then User X gets 100 bonus credits. Has anybody built a referral system before and if so what obstacles should I bear in mind? I've had a snoop round SO tonight but couldn't find any suitable answers. My theory is to give each user a random string which is generated and stored in the DB when they sign up, The user will then be presented with a URL incl. that string which when they pass to somebody (User Z), User Z is then sent to a page, the page then uses the GET method to gather the Random string and update the DB Row they currently occupy, does this sound feasible or could it easily be breached? Thanks

  • How do I supply values to an referenced assembly without calling a method it explicitly?

    - by Rob
    Currently I have a static class that I use as my logging module. I’ve added the class to my visual studio solution. Within the class I’ve specified the name and location of the log file to use. Which lets me do stuff like this – which I like and want. Logger.Information(“Page_Load”,”controls loaded correctly”); I’d like to refactor the code and move the logging functionality into a separately compiled assembly, if I did this I would then need to pass in the log file name and location to save the files too. However I don’t want to have to supply this information every time I call the ‘Logging’ method, this would be bad... Logger.Informtaion(“Page_Load”,”controls loaded correctly”,”logfile.txt”,”c:\temp”); Is there any way I can supply this information without having to specify it within each page or via the method call.

  • Auto Re-Running of Tests that fail

    - by Tangopop
    I have a set of Selenium/MbUnit Tests that work fine, but tend to take a while to run (over 4 hours) A problem i am finding is that about 1 in 20 test seems to timeout when running. I have confirmed the Selenium GRID is working and the Selenium RC's are all fine, it just seems to be a qwerk of the system. What is really annoying though is that if i run these tests again they will usually pass. What i want to know is if there is a way for me to auto rerun the tests (probably in the code) if a perticular type of exception is caught... I have attempted to put a few lines of code in the catch statement but i know this is a very hacky way of re running the tests. Here is the code: catch (AssertionException e) { if (e.Message() == "TimeOut") //Something similar to this { this.Test(); } else { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } } Any suggestions?

  • What did I do wrong here when trying to unit test a class that references a web service

    - by zachary
    So I had a class that referenced a class that referenced another class that called a web service. So I learn how to create an interface using partial classes. I inject the web service through the constructor. Then my unit test fails because I am newing up the actual web service in the second level of the class. So I end up modifying all three classes to pass the web service down through the constructor... was not happy :-( gave up.... what should I be doing in this case?

  • Is it possible to remove all event handlers of a given element in javascript?

    - by MartyIX
    Hi, I would like to remove ALL handlers for a given event type. Let's say I've added twice "onclick event" to a button and now I would like to return back to the original state where no event handler was set to the button. How can I do that? P.S.: I've found removeEventListener (non-IE)/detachEvent (IE) methods but the functions want me to pass as a parameter the function that handles the event which seems to me quite clumsy because I would have to store the functions somewhere. EDIT: http://ejohn.org/blog/flexible-javascript-events/ - I'm now using this code Thank you!

  • How can I embed a flash movie in a zend view programmatically?

    - by curro
    I have tried to embed a flash movie in a zend view using the htmlFlash helper. In theory you only have to pass the movie path to the htmlFlash helper in a phtml view: echo $this-htmlFlash('/path/to/myMovie.swf'); And the framework will generate the html code in the html page: <object data="/path/to/flash.swf" type="application/x-shockwave-flash" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab"> </object> However, I have done so and the code doesn't appear on the source code. Has anyone had this problem? Thank you

  • ColdFusion Timeout Error

    - by Jason
    I have a scheduled task that runs once a day that builds an XML file that I pass off to another group. Recently the amount of data has greatly increased and is now causing the task to time out (I think). I have tried to optimize my script as much as possible but with no luck. It times out long before an hour and I don't get any kind of ColdFusion error. Instead I get a "This page cannot be found" after it runs. Could this be a timeout someplace other than Coldfusion? Is there a more efficient way to build this XML file? select PersonID, FirstName, LastName from People select d.DepartmentID, DepartmentName, pd.PersonID from Department d inner join PersonDepartment pd on d.DepartmentID = pd.DepartmentID select PaperID, PaperTitle, PaperDescription, pp.PersonID from Paper p inner join PersonPaper pp on p.PaperID = pp.PaperID select DepartmentID, DepartmentName from getDepartments where PersonID = #getPeople.PersonID# select PaperID, PaperDescription from getpapers where PersonID = #getPeople.PersonID# #getPeople.PersonID# #getPeople.Firstname# #getPeople.LastName# #getPersonDepartments.DepartmentID# #getPersonDepartments.DepartmentName# #getPersonPapers.PaperID# #getPersonPapers.PaperDescription# Done!

  • escaping query string with special characters with python

    - by that_guy
    I got some pretty messy urls that i got via scraping here, problem is that they contain spaces or other special characters in the path and query string, here is some example http://www.example.com/some path/to the/file.html http://www.example.com/some path/?file=path to/file name.png&name=name.me so, is there an easy and robust way to escape the urls so that i can pass them to urlopen? i tried urlib.quote, but it seems to escape the '?', '&', and '=' in the query string as well, and it seems to escape the protocol as well, currently, what i am trying to do is use regex to separate the protocol, path name, and query string and escape them separately, but there are cases where they arent separated properly any advice is appreciated

  • Are Sting int values guaranteed to be constant over different projects

    - by jax
    I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English. So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?

    Hi, I'm using java servlets and jsp in my application and I need to read the remote XML file and properly render it into HTML and display on a web page...What is the technology used for reading process?Should I use HTTPURLConnection class to read the contents of the xml file or there is some other way? And also,if I use servlet as a controller and JSP as a view,what would be the responsibility of servlet and jsp in this process?Should servlet just read the whole XML file and then just pass the read output to JSP which will just print it and render properly using XSL for example? I really hope to hear from any people who may help, With kind regards

  • C# Spawn Multiple Threads for work then wait until all finished

    - by pharoc
    just want some advice on "best practice" regarding multi-threading tasks. as an example, we have a C# application that upon startup reads data from various "type" table in our database and stores the information in a collection which we pass around the application. this prevents us from hitting the database each time this information is required. at the moment the application is reading data from 10 tables synchronously. i would really like to have the application read from each table in a different thread all running in parallel. the application would wait for all the threads to complete before continuing with the startup of the application. i have looked into BackGroundWorker but just want some advice on accomplishing the above. Does the method sound logical in order to speed up the startup time of our application How can we best handle all the threads keeping in mind that each thread's work is independent of one another, we just need to wait for all the threads to complete before continuing. i look forward to some answers

  • Access to bytes array of a Bitmap

    - by Deulis
    1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?

  • Can you make VB.NET compilation as strict as C#?

    - by pete the pagan-gerbil
    In VB.NET, it is entirely possible to pass an integer as a string parameter to a method without calling .ToString() - it's even possible to call .ToString without the ()'s. The code will run without a problem, VB will interpret the integer as a string without having been told to. In C#, these would cause compilation errors - you are required to call .ToString() and to call it correctly in that situation before it will compile. Is there a way to make the VB compilation process check for the same things as the C# compilation process? Would it be best practice in a mixed team to force this check?
