• Magento - Authorize.net - Get Payment Update for expired transactions

  - by pspahn

  Magento 1.6.1 I have set up Authorize.net (AIM) for the client's store. Previously they were using saved CC method and entering information manually in Authorize.net's merchant terminal. Most of it is working as expected, however for transactions that are flagged as 'Suspected Fraud' by Authorize.net, if the client does not update the transaction manually before the authorization expires, using 'Get Payment Update' in Magento fails because the transaction is expired (I believe it's five days for an authorize only transaction). For the client, it seems the only way to update this order in Magento is to simply delete the order, as it doesn't appear the Paygate model knows about expired transactions. Performing 'Get Payment Update' simply returns 'There is no update for this payment'. I have already modified the file: /app/code/core/Mage/Paygate/Model/Authorize.net to have the correct API URL as described in issue #27117 ( http://www.magentocommerce.com/bug-tracking/issue?issue=12991 - must be logged in to view ). This resolved the button not working for all other orders; however this does not fix the issue I am describing. Is anyone familiar with Authorize.net's AIM API so that we can update these orders in Magento to something that makes sense (canceled, etc.) without having to delete the order? I am thinking it should be a case of adding a new order status to Magento, checking the update for an 'Expired' status, and setting the order to the newly created order status. -- edit -- I just ran a diff for the file mentioned above and noticed that Magento 1.7.0.2 includes the _isTransactionExpired() method which seems like it would be the fix. Can it be as simple as updating this model with the newer version?

• Google Javascript v8 - multithreading

  - by willem

  Hi guys Suppose I have the following piece of code bool run (void) { HandleScope hande_scope; Handle<String> source; Local<Script> script; Persistent<Context> context; context = Context::New(); Context::Scope context_scope(context); script = Script::Compile("var a = 1; var b = 2;"); Local<Value> result = script->Run(); if (result.IsEmpty()) return false; else return true; } Is it true that one cannot execute this code using multiple threads? It seems like HandleScope is not designed to be used in multithreaded applications. I can use the v8::Locker and v8::Unlocker methodes but that would always give me execution traces as this: t1: a = 1 t1: b = 2 t2: a = 1 t2: b = 2 I hope someone can give me a hint on getting this code multithreaded so that a possible execution trace could like this: t1: a = 1 t2: a = 1 t1: b = 2 t2: b = 2 Thanks already in advance! Willem -- EDIT -- So I guess that this question has no answer :)

• Help me create a Firefox extension (Javascript XPCOM Component)

  - by Johnny Grass

  I've been looking at different tutorials and I know I'm close but I'm getting lost in implementation details because some of them are a little bit dated and a few things have changed since Firefox 3. I have already written the javascript for the firefox extension, now I need to make it into an XPCOM component. This is the functionality that I need: My Javascript file is simple, I have two functions startServer() and stopServer. I need to run startServer() when the browser starts and stopServer() when firefox quits. Edit: I've updated my code with a working solution (thanks to Neil). The following is in MyExtension/components/myextension.js. Components.utils.import("resource://gre/modules/XPCOMUtils.jsm"); const CI = Components.interfaces, CC = Components.classes, CR = Components.results; // class declaration function MyExtension() {} MyExtension.prototype = { classDescription: "My Firefox Extension", classID: Components.ID("{xxxx-xxxx-xxx-xxxxx}"), contractID: "@example.com/MyExtension;1", QueryInterface: XPCOMUtils.generateQI([CI.nsIObserver]), // add to category manager _xpcom_categories: [{ category: "profile-after-change" }], // start socket server startServer: function () { /* socket initialization code */ }, // stop socket server stopServer: function () { /* stop server */ }, observe: function(aSubject, aTopic, aData) { var obs = CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService); switch (aTopic) { case "quit-application": this.stopServer(); obs.removeObserver(this, "quit-application"); break; case "profile-after-change": this.startServer(); obs.addObserver(this, "quit-application", false); break; default: throw Components.Exception("Unknown topic: " + aTopic); } } }; var components = [MyExtension]; function NSGetModule(compMgr, fileSpec) { return XPCOMUtils.generateModule(components); }

• Question about functional OOP style in JavaScript

  - by valums

  I prefer to use functional OOP style for my code (similar to the module pattern) because it helps me to avoid the "new" keyword and all problems with the scope of "this" keyword in callbacks. But I've run into a few minor issues with it. I would like to use the following code to create a class. namespace.myClass = function(){ var self = {}, somePrivateVar1; // initialization code that would call // private or public methods privateMethod(); self.publicMethod(); // sorry, error here function privateMethod(){} self.publicMethod = function(){}; return self; } The problem is that I can't call public methods from my initialization code, as these functions are not defined yet. The obvious solution would be to create an init method, and call it before "return self" line. But maybe you know a more elegant solution? Also, how do you usually handle inheritance with this pattern? I use the following code, butI would like to hear your ideas and suggestions. namespace.myClass2 = function(){ var self = namespace.parentClass(), somePrivateVar1; var superMethod = self.someMethod; self.someMethod = function(){ // example shows how to overwrite parent methods superMethod(); }; return self; } Edit. For those who asked what are the reasons for choosing this style of OOP, you can look into following questions: http://stackoverflow.com/questions/1557386/prototypal-vs-functional-oop-in-javascript http://stackoverflow.com/questions/383402/is-javascript-s-new-keyword-considered-harmful

• How to select and crop an image in android?

  - by Guy

  Hey, I am currently working on a live wallpaper and I allow the user to select an image which will go behind my effects. Currently I have: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); i.putExtra("crop", "true"); startActivityForResult(i, 1); And slightly under that: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); Log.d("IMAGE SEL", "" + selectedImage); // TODO Do something with the select image URI SharedPreferences customSharedPreference = getSharedPreferences("imagePref", Activity.MODE_PRIVATE); SharedPreferences.Editor editor = customSharedPreference.edit(); Log.d("HO", "" + selectedImage); editor.putString("imagePref", getRealPathFromURI(selectedImage)); Log.d("IMAGE SEL", getRealPathFromURI(selectedImage)); editor.commit(); } } When my code is ran, Logcat tells me that selectedImage is null. If I comment out the i.putExtra("crop", "true"): Logcat does not give me the null pointer exception, and I am able to do what I want with the image. So, what is the problem here? Does any one have any idea how I can fix this? Thanks, for your time.

• Linux 2.6.31 Scheduler and Multithreaded Jobs

  - by dsimcha

  I run massively parallel scientific computing jobs on a shared Linux computer with 24 cores. Most of the time my jobs are capable of scaling to 24 cores when nothing else is running on this computer. However, it seems like when even one single-threaded job that isn't mine is running, my 24-thread jobs (which I set for high nice values) only manage to get ~1800% CPU (using Linux notation). Meanwhile, about 500% of the CPU cycles (again, using Linux notation) are idle. Can anyone explain this behavior and what I can do about it to get all of the 23 cores that aren't being used by someone else? Notes: In case it's relevant, I have observed this on slightly different kernel versions, though I can't remember which off the top of my head. The CPU architecture is x64. Is it at all possible that the fact that my 24-core jobs are 32-bit and the other jobs I'm competing w/ are 64-bit is relevant? Edit: One thing I just noticed is that going up to 30 threads seems to alleviate the problem to some degree. It gets me up to ~2100% CPU.

• Adding a guideline to the editor in Visual Studio

  - by xsl

  Introduction I've always been searching for a way to make Visual Studio draw a line after a certain amount of characters: Below is a guide to enable these so called guidelines for various versions of Visual Studio. Visual Studio 2010 Install Paul Harrington's Editor Guidelines extension. Open the registry at HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\Text Editor and add a new string called Guides with the value RGB(100,100,100), 80. The first part specifies the color, while the other one (80) is the column the line will be displayed. Or install the Guidelines UI extension, which will add entries to the editor's context menu for adding/removing the entries without needing to edit the registry directly. The current disadvantage of this method is that you can't specify the column directly. Visual Studio 2008 and Other Versions If you are using Visual Studio 2008 open the registry at HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Text Editor and add a new string called Guides with the value RGB(100,100,100), 80. The first part specifies the color, while the other one (80) is the column the line will be displayed. The vertical line will appear, when you restart Visual Studio. This trick also works for various other version of Visual Studio, as long as you use the correct path: 2003: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\7.1\Text Editor 2005: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Text Editor 2008: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Text Editor 2008 Express: HKEY_CURRENT_USER\Software\Microsoft\VCExpress\9.0\Text Editor This also works in SQL Server 2005 and probably other versions.

• SVN checkout browser

  - by phazei

  I've been looking all over for a SVN browser. Now I'm not talking about anything like WebSVN or TRAC, I don't want to browse the repository; I want to browse the checkout. I'm looking for a program that lets me browse the checkout (working copy) and shows me the info I'd normally need to SSH for. So I could mark specific files or folders for some commit button, or see the status, or view a diff between the working and a prev version. Basically a web GUI for a svn checkout. A [windows] program that can let you work on a remote checkout as if it were local would also work. Currently I have a checkout on my server running under dev.mysite.com. I log in via ftp and edit and upload the files. I also keep SSH open so I can do a svn st to see what files I've worked on and to commit changes. I want to work on the files on the same environment so I can't simply use a local checkout. But I don't want to need to work via SSH. Are there any apps such as I described? Like a repo browser but for checkouts to do commits. Like WebTortoiseSVN or such. Thanks

• What is the best way to do testing database (MYSQL spesific)

  - by justjoe

  Right now i'm on testing something in a database. It's a wordpress database. i have to write and delete and do other operation on it. As you know it, it has indexing mechanism that will always make every new post inherit the next highest possible ID. Please consider that this database is a copying of used database. it has been written before. So, i will need to make sure when i finish my testing, it will be the same Right now, my only solution is making backup. So if i have end in some section of planned testing, i will backup it and start next testing on another copy of it. Fortunately, the size of database is only a small one. so delete and copy and backup it will be easy. but i know this way of database testing is only partial solution.It force me to create too many backup copy. I don't know what i will do if the database has bigger size. it will be a very long of testing nightmare. so i wonder is there any solution that work just like rollback. So it will just lock the database and just put new entry as some kind of cache. I can erase it or write it into the database. i use mysql and phpmyadmin and use it to developed some custom solution. EDIT ::: How to effectively doing testing on database when developing PHP solution ?

• Winforms: How to display a "loading" form?

  - by Martijn

  I have a grid and when a row is double clicked a form is loaded. However a lot of data must be loaded, so I'd like to display a simple form with the text 'loading, please wait..'. And when all loading is finished, the form must disappear. This is what I have right now, but it doesn't work: Code that invokes the form with lots of data: FormWithLotData form = new FormWithLotData(); form.ShowDialog(this); Constructor of FormWithLotData: // Show load form FormIsLoading frm = new FormIsLoading(); _CloseLoadForm closeForm = new _CloseLoadForm(frm.Close); System.Threading.Thread thread = new System.Threading.Thread(frm.Show); thread.Start(); InitializeComponent(); this.Visible = false; LoadAllData(); this.Visible = true; // Close load form Invoke(closeForm); Hope you can help me out. EDIT: I'd like to show an animated gif on the loading form.

• MD5 Hashing Given a Key in C#

  - by Jared

  I've been looking for a way to hash a given string in C# that uses a predetermined key. On my adventures through the internet trying to find an example i have seen lots of MD5CryptoServiceProvider examples which seem to use a default key for the machine, but none of them that apply a specific key. I need to have a specific key to encode data as to synchronize it to someone else's server. I hand them a hashed string and an ID number and they use that analyze the data and return a similar set to me. So is there anyway to get md5 to hash via a specific key that would be consistent to both. I would prefer this to be done in C#, but if its not possible with the libraries can you do so with some web languages like php or asp? Edit: Misunderstood the scenario I was thrown into and after a little sitting and thinking about why they would have me use a key it appears they want a key appended to the end of the string and hashed. That way the server can appended the key it has along with the data passed to ensure its a valid accessing computer. Anyways... thanks all ^_^ Edit2: As my comment below says, it was the term 'salting' I was oblivious to. Oh the joys of getting thrown into something new with no directions.

• Databinding question: DataGridView <=> XDocument (using LINQ-to-XML)

  - by Pretzel

  Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• 3n+1 problem at UVa

  Hello, I am having trouble with the first question in the Programming Challenges book by Skiena and Revilla. I keep getting a "Wrong Answer" error message, and I don't know why. I've ran my code against the sample input, and I keep getting the right answer. Anyways, if anyone could help me, I would really appreciate it :) Here is the problem URL: http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&category=29&page=show_problem&problem=36 And here is the code:` import java.util.Scanner; public class Main { static Scanner kb = new Scanner(System.in); public static void main(String[] args) { while (kb.hasNext()) { long[] numericalInput = {0, 0}; long i = kb.nextLong(); long j = kb.nextLong(); if (i > j) { numericalInput[0] = i; numericalInput[1] = j; } else { numericalInput[0] = j; numericalInput[1] = i; } long maxIterations = 0; for (long n = numericalInput[0]; n <= numericalInput[1]; n += 1) { if (maxIterations < returnIterations(n)) maxIterations = returnIterations(n); } System.out.println(i + " " + j + " " + maxIterations); } System.exit(0); } public static long returnIterations(long num) { long iterations = 0; while (num != 1) { if (num % 2 == 0) num = num / 2; else num = 3 * num + 1; iterations += 1; } iterations += 1; return iterations; } } ` EDIT: I think the problem is with the output. I tried to make it accept all the input first and then display all the answers at once, but I didn't know the terminating condition. I resorted to this method, but I'm not sure that's what the judge wants...

• Dashcode code translation

  - by Alex Mcp

  Hi, a quick, probably easy question whose answer is probably "best practice" I'm following a tutorial for a custom-template mobile Safari webapp, and to change views around this code is used: function btnSave_ClickHandler(event) { var views = document.getElementById('stackLayout'); var front = document.getElementById('mainScreen'); if (views && views.object && front) { views.object.setCurrentView(front, true); } } My question is just about the if conditional statement. What is this triplet saying, and why do each of those things need to be verified before the view can be changed? Does views.object just test to see if the views variable responds to the object method? Why is this important? EDIT - This is/was the main point of this question, and it regards not Javascript as a language and how if loops work, but rather WHY these 3 things specifically need to be checked: Under what scenarios might views and front not exist? I don't typically write my code so redundantly. If the name of my MySQL table isn't changing, I'll just say UPDATE 'mytable' WHERE... instead of the much more verbose (and in my view, redundant) $mytable = "TheSQLTableName"; if ($mytable == an actual table && $mytable exists && entries can be updated){ UPDATE $mytable; } Whereas if the table's name (or in the JS example, the view's names) ARE NOT "hard coded" but are instead a user input or otherwise mutable, I might right my code as the DashCode example has it. So tell me, can these values "go wrong" anyhow? Thanks!

• Multiple dynamic timers

  - by Rickard

  I am working on a project where I need to let the user create one (or more) timers to fire off an event. The user is supposed to define variables such as if the timer should be active and how often the timer will fire along with some other variables of what will happen when the timer is fiering. All these variables are stored in a dictionary (Disctionary) where the object holds all the variables the user has set and the string is the name that the user has chosen for this timer. I then want my program to loop through this dictionary and search for all objects which has the variable t_Active set to true (this I have already achieved). What I need help with figuring out is the follwoing: When it detects the variable, and if it's set to true, I need the program to see if there is already a timer created for this. If it isn't, it should create one and set the relevant parameters for the timer. The two variables t_num and t_period should decide the interval of the timer. t_num is an int and t_period is a string which will be set to either minutes, hours or days. Combining t_num with 60000 (minutes), 3600000 (hours) or 86400000 should give the corrct interval. But how would I go on about programatically create a timer for each user-defined active object? And how do I get the program to detect wether or not a timer has already been created? I have been searching both here and on google, but so far I haven't come across something that makes sense to me. I am still learning C#, so what make sense to you guys may not neccessarilly make sense to me yet. :) I hope I have explaned what I need good enough, please do ask me to clarify if you don't get me. Edit: Maybe I should also mention that the mentioned dictionary will also be saved to an XML file to that the user can pick up all the settings they made at any time.

• jquery: prepopulating autocomplete fields

  - by David Tildon

  I'm using the tokenizing autocomplete plugin for jquery ( http://loopj.com/2009/04/25/jquery-plugin-tokenizing-autocomplete-text-entry ). I mostly use Ruby, and I'm really unfamiliar with javascript, though. My basic setup looks like this, and works fine for a new, blank form: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search" }); }); The problem comes when I try to prepopulate it, like for an edit page. I'm trying to do something like this (where the "#tag_ids_field" text box contains the JSON when the page is loaded - that way is just cleaner on the application side of things). $(document).ready(function () { var tags = $("#tag_ids_field").html(); $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: tags }); }); However, when the page loads I see that it's just filled with hundreds of entries that read 'undefined'. I get this even if I take the JSON output that Rails provides and try sticking it right in the .js file: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: "[{\"id\":\"44\",\"name\":\"omnis sit impedit et numquam voluptas enim\"},{\"id\":\"515\",\"name\":\"deserunt odit id doloremque reiciendis aliquid qui vel\"},{\"id\":\"943\",\"name\":\"exercitationem numquam possimus quasi iste nisi illum\"}]" }); }); That's obviously not a solution, I just tried it out of frustration and I get the same behavior. My two questions: One, why are my text boxes being filled with "undefined" tags when I try to prepopulate, and how can I get them to prepopulate successfully? Two, I'm planning on having many autocomplete fields like this on the same page (for when several records are edited at once - they all query the same place). How can I make each autocomplete field take it's prepopulated values from it's own textbox? Something like (applying these settings to all input boxes with a certain class, not just the one of a particular id): $(document).ready(function () { $(".tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: (the contents of that particular ".tag_ids_field" input box) }); });

• jQuery - script tags in the HTML are parsed out by jQuery and not executed

  - by Jose Jose

  I have an HTML page like so: <html> <body> <div id='something'> ... <script> var x = 'hello world'; </script> ... </div> </body> </html> On another page, I am doing this: $.ajax({ url: 'example.html', type: 'GET', success: function(data) { $('#mydiv').html($(data).find('#something').html()); alert(x); } }); jQuery, however, is not executing the javascript in the first file, even though the documentation says it does. How can I make it do that? EDIT: Unfortunately in the real world application I am working on I don't have control over what the "included" page has. We are on the same domain, but I can't modify the code that it outputs as it is a packaged product our IT department will not let us modify.

• how to combine widget webapp framework with SEO-friendly CSS and JS files

  - by Ali

  Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

• jquery click an img hide an LI

  i have something similar to the following... used a python script to JSON to populate. <ul> <li id="p1" class="x">val1 <img id="ip1" class="redx" src="redx.gif"/></li> <li id="p2" class="x">val2 <img id="ip2" class="redx" src="redx.gif"/></li> <li id="p3" class="x">val3 <img id="ip3" class="redx" src="redx.gif"/></li> <li id="p4" class="x">val4 <img id="ip4" class="redx" src="redx.gif"/></li> </ul> I'd like some jquery to... when click the red x image.. to hide the whole LI cell it is in. I have tried a few things but ... to no avail. EDIT: All in all.. this doesnt seem to trigger ... this seems like a fundamental issue. $(function(){ function removeli() { alert("got here" + this.id); } $("redx").click(removeli); }); Any ideas on the final jquery code to accomplish this?

• HttpWebRequest Timeouts After Ten Consecutive Requests

  - by Bob Mc

  I'm writing a web crawler for a specific site. The application is a VB.Net Windows Forms application that is not using multiple threads - each web request is consecutive. However, after ten successful page retrievals every successive request times out. I have reviewed the similar questions already posted here on SO, and have implemented the recommended techniques into my GetPage routine, shown below: Public Function GetPage(ByVal url As String) As String Dim result As String = String.Empty Dim uri As New Uri(url) Dim sp As ServicePoint = ServicePointManager.FindServicePoint(uri) sp.ConnectionLimit = 100 Dim request As HttpWebRequest = WebRequest.Create(uri) request.KeepAlive = False request.Timeout = 15000 Try Using response As HttpWebResponse = DirectCast(request.GetResponse, HttpWebResponse) Using dataStream As Stream = response.GetResponseStream() Using reader As New StreamReader(dataStream) If response.StatusCode <> HttpStatusCode.OK Then Throw New Exception("Got response status code: " + response.StatusCode) End If result = reader.ReadToEnd() End Using End Using response.Close() End Using Catch ex As Exception Dim msg As String = "Error reading page """ & url & """. " & ex.Message Logger.LogMessage(msg, LogOutputLevel.Diagnostics) End Try Return result End Function Have I missed something? Am I not closing or disposing of an object that should be? It seems strange that it always happens after ten consecutive requests. Notes: In the constructor for the class in which this method resides I have the following: ServicePointManager.DefaultConnectionLimit = 100 If I set KeepAlive to true, the timeouts begin after five requests. All the requests are for pages in the same domain. EDIT I added a delay between each web request of between two and seven seconds so that I do not appear to be "hammering" the site or attempting a DOS attack. However, the problem still occurs.

• Why can't I set boolean columns with update?

  - by Benjamin Oakes

  I'm making a user administration page. For the system I'm creating, users need to be approved. Sometimes, there will be many users to approve, so I'd like to make that easy. I'm storing this as a boolean column called approved. I remembered the Edit Multiple Individually Railscast and thought it would be a great fit. However, I'm running into problems which I traced back to ActiveRecord::Base#update. update works fine in this example: >> User.all.map(&:username) => ["ben", "fred"] >> h = {"1"=>{'username'=>'benjamin'}, "2"=>{"username"=>'frederick'}} => {"1"=>{"username"=>"benjamin"}, "2"=>{"username"=>"frederick"}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:username) => ["benjamin", "frederick"] But not this one: >> User.all.map(&:approved) => [true, nil] >> h = {"1"=>{'approved'=>'1'}, "2"=>{'approved'=>'1'}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:approved) => [true, nil] Chaging from '1' to true didn't make a difference when I tested. What am I doing wrong?

• Hidden controls, iframes or divs

  - by user287745

  What happens to the controls or the iframe or the div, which are hidden? Do they get transferred to the user side? Disabled: does it get transferred to the user side? What I want is, an aspx page will be having many iframes to display different pages. There will be many div tags to display CSS formatted information. To understand what I mean by many:- I have to transfer a complete website with 30 aspx pages into one single page! I have simply combined everything resulting in one extremely huge page. My concern is that on local host it loads fast, but when on online server accessed by numerous people for education purposes, the site (ONE PAGE) WILL SLOW DOWN terribly. To overcome this I thought of using hidden and disable options. What is an improved way of achieving the above? Yes, it sounds silly but this is the requirement. Edit: Yes, I know id and server tag must be set, but what I am asking will the div tag be sent to the user's browser? One answer is no. So can I enable them using JavaScript? Like document.getElementById(id).style.visibility="visible" What if I disable them, and from coding of JavaScript enable them? Will they be loaded at the time of enabling?

• ASP.NET dynamically reassign controls in the control tree

  - by pbz

  Let's say I have a custom control that looks like this <cc:MyControl runat="server" ID="myc" LinkControlID="NewParent" /> and, on the same page: <asp:TextBox runat="server" ID="NewParent" /> What I would like to do is, from MyControl, change NewParent's parent so that it would be part of MyControl's Controls collection. When I try to do this, from OnInit, I get: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. Which makes sense, but is there a way around this? I'm OK if NewParent remains the child of the Page as long as from MyControl I can somehow redirect the rendering to MyControl's control. Can this be done? Thanks. EDIT: To clarify here's a mockup of MyControl: public class MyControl : Panel { protected override void OnInit(System.EventArgs e) { base.OnInit(e); if (!String.IsNullOrEmpty(LinkControlID)) { Control link = Parent.FindControl(LinkControlID); if (link != null) { Controls.Add(link); } } } public string LinkControlID { get; set; } } This assumes that MyControl and LinkControlID are placed on the same level in the tree hierarchy, which is OK in my case.

• Get a JQuery function to execute after and independently of onLoad

  - by lewicki

  Is is possible to execute a JQuery function by injecting it into the page? IT CAN'T be attached to the .ready function. The reason is that the user will be uploading an image via iframe. I need JCrop to execute after I display the uploaded image. echo "<script>$('#pictures_step1_right_bottom1', window.parent.document).html('<img id=\"cropbox\" src=\"../../box/" . 'THM' . $filenameAlt . '.jpg' . "\">');</script>"; echo "<script>jQuery(function(){jQuery('#cropbox').Jcrop();});</script>"; This is executed in the iframe that is processing the image. it then sends it to the main page. This does not work however. EDIT: Ended up running a timer: function checkPic() { if($('#cropbox1').length != 0) { jQuery(function() { jQuery('#cropbox1').Jcrop(); }); } timer(); // Check size again after 1 second } function timer(){ var myTimer = setTimeout('checkPic()', 3000); // Check size every 1 second}
