• Cannot run/debug Java applications in Eclipse (JavaTimeZone issue)

  - by Andre

  I'm trying to get started with Eclipse/Java/Scala on a MacBook. The installed JDK was 1.5. The SDT plugin for Scala requires 1.6 which was included in an OS update, but I also manually installed a package from Apple to update 1.6. The problem is that I cannot run anything from Eclipse. I always get the following error: An internal error occurred during: "Launching TestFooBasicTest". Could not initialize class com.ibm.icu.impl.JavaTimeZone I also tried to use the old 1.5 version, but to no avail. What is going wrong here?

• Detect if a table contains a column in Android/sqlite

  - by sandis

  So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function. Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution. Cheers,

• Paypal subscription API - transaction variables not POSTed

  - by morpheous

  I am writing a payments system based around paypal, I am using the HTML 'API'. I am passing the following form fields to PayPal: 'rm' = 2 'return = http://www.example.com/payment-handler.php?token=sometoken Where 'token' is a token I generated. According to the paypal documentation, a return method (rm) of 2 indicates to Paypal that the transaction data be posted back to the callback url using the POST method. When processing items using 'buy_now' buttons, the transaction items are correctly POSTed to my callback url (payment-handler.php), but for 'subscribe' operations, although the callback url is called, no POST data is sent to the url, and also, the 'token' field is missing. Instead, there is a parameter called 'auth'. I cant see anything in the paypal docs about a 'auth' field - so I dont know whats generating it and if I can reliably using it. Can anyone shed some light on this?

• Regarding Multiple Tab-Class

  - by Christine

  Hi! I've problem regarding GUI with one Menu and one Order Class. I've created a variable to store how many items have been selected in the Menu Class. private int totalSelected; The var totalSelected is live updated. It can be changed anytime depending on actionPerformed() function.(Exp: totalSelected will add up all the selected items) In the Order Class, how can I access to the live update variable totalSelected in order to retrieve the live update value? When I invoke getTotalSelected() function inside the Menu Class, I will only obtain a 0 value. Thanks for your help ^^!

• BindingList projection wrapper

  - by Groo

  Is there a simple way to create a BindingList wrapper (with projection), which would update as the original list updates? For example, let's say I have a mutable list of numbers, and I want to represent them as hex strings in a ComboBox. Using this wrapper I could do something like this: BindingList<int> numbers = data.GetNumbers(); comboBox.DataSource = Project(numbers, i => string.Format("{0:x}", i)); I could wrap the list into a new BindingList, handle all source events, update the list and fire these events again, but I feel that there is a simpler way already.

• Drools Rules: How can I use a method on "when" section?

  - by manoelhc

  Hi, I need to execute a method on "when" section of a DSLR file and I´m not sure if it´s possible. Example: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(isInAgeRange("30-100")==true) Reminder(clickPercentual >= 10) User(haveAtLeastOptIns("1,2,3,4") == true) then $reminder.setPriority(1);update($reminder); end (note: isInAgeRange() and haveAtLeastOptIns() are methods of User) I tried with eval() and no errors appeared, but it didn´t execute. Like this: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(eval($user.isInAgeRange("30-100")==true)) Reminder(clickPercentual >= 10) User(eval($user.haveAtLeastOptIns("1,2,3,4") == true)) then $reminder.setPriority(1);update($reminder); end How can I resolve this problem?

• Boiler plate code replacement - is there anything bad about this code?

  - by Benjol

  I've recently created these two (unrelated) methods to replace lots of boiler-plate code in my winforms application. As far as I can tell, they work ok, but I need some reassurance/advice on whether there are some problems I might be missing. (from memory) static class SafeInvoker { //Utility to avoid boiler-plate InvokeRequired code //Usage: SafeInvoker.Invoke(myCtrl, () => myCtrl.Enabled = false); public static void Invoke(Control ctrl, Action cmd) { if (ctrl.InvokeRequired) ctrl.BeginInvoke(new MethodInvoker(cmd)); else cmd(); } //Replaces OnMyEventRaised boiler-plate code //Usage: SafeInvoker.RaiseEvent(this, MyEventRaised) public static void RaiseEvent(object sender, EventHandler evnt) { var handler = evnt; if (handler != null) handler(sender, EventArgs.Empty); } } EDIT: See related question here UPDATE Following on from deadlock problems (related in this question), I have switched from Invoke to BeginInvoke (see an explanation here). Another Update Regarding the second snippet, I am increasingly inclined to use the 'empty delegate' pattern, which fixes this problem 'at source' by declaring the event directly with an empty handler, like so: event EventHandler MyEventRaised = delegate {};

• Building dictionary of words from large text

  - by LiorH

  I have a text file containing posts in English/Italian. I would like to read the posts into a data matrix so that each row represents a post and each column a word. The cells in the matrix are the counts of how many times each word appears in the post. The dictionary should consist of all the words in the whole file or a non exhaustive English/Italian dictionary. I know this is a common essential preprocessing step for NLP. Does anyone know of a tool\project that can perform this task? Someone mentioned apache lucene, do you know if lucene index can be serialized to a data-structure similar to my needs?

• jQuery to PHP: no input... kinda

  - by Seva Alekseyev

  Hi all, I'm using jQuery to post HTTP requests to my PHP page (Apache/Linux, if that matters). I carefully validate on the client so that empty requests are not sent. However on occasions, I'd get an empty request like this: - $_POST collection empty ($_GET collection also empty); - Content-Length is nonzero (a number below 100, consistent with a valid POST from my script) - Content-Type properly application/x-www-form-urlencoded - reading from php://input yields an empty string It's as if $_POST is somehow eaten on the way. I checked the code very carefully - I don't do anything to the contents of $_POST. Any ideas, please?

• In JQuery 1.4.2 .ajax converts JSON wrong.

  - by Carl

  My code worked fine in JQuery 1.3.2, but in 1.4.2 it seems to be broken. What is should get in the post is something like this: ?pks=108;pks=107 What I now get is: ?pks[]=108;pks[]=107; When I trace this code through, the JSON object seems to be fine until it enters .ajax. Firebug after the response is received shows the post was: Parameters application/x-www-form-urlencoded pks[] 108 pks[] 107 Source pks%5B%5D=108&pks%5B%5D=107 Which is not what I got on JQuery 1.3.2. Where are those extra braces coming from?

• solution for COMET and PHP

  - by codemaker

  Is there a real solution for COMET AND PHP combination? Basically, I've come to a point that I need to update a user home page periodically whenever there is new data in the database. As far as I understand, I need to open a persistent connection between my server and my clients browsers to update the contents of their home page as soon as new info. available without dedicating a lot of resources but I had no luck finding anything clear about this issue. I read many articles suggests that PHP is not a good language to implement COMET. My web application is completely programmed in PHP and I don't want to learn another language but if I'm forced to, Would you suggest a good language to start with? Do you think that I can program an interface just to handle this issue? Thanks in advance.

• Microsoft BizTalk Server vNext (after 2009 R2) - Feature Request

  - by Saravana Kumar

  All, This post is not a question; it’s more of asking for feed back and future request. The product team is always looking for feed back to facilitate the future direction of the product. Some of us as BizTalk Server MVP’s/partners get that privilege to work with the product team closely to give our feedback regularly based on our real world experience. But I believe there is a much wider BizTalk community out there working on closed door project that tests the strength of the product to extreme levels. I would like those passionate people to come forward and put their feature request. Let’s use the power of StackOverflow to help us here. We can vote up and down on each feature request, and see what's going to top the chart. I hope this will be a useful exercise. Updated 24th Feb: If you got more than one request, please post it as separate answers. So, its easy to vote against them.

• AppEngine BlobStore upload failing with a request that works in the Development Environment

  - by Joe Ludwig

  I have an AppEngine application that uses the blobstore to store user-provided image data. When I upload images to that application from a form in Chrome it works fine. When I try to upload an image from an Android application it fails. Both methods work fine if I am running against the development server, but the Android upload doesn't work against the live service. This is the request from Chrome: POST /_ah/upload/?userToken=11001/AMmfu6ZCyMQQ9YdiXal3SmSXIRTQIuSRXkNc-i3JmU0fqx_kJbUJ2OMLcS2lXhVJSK4qs7regViTKzOPz5ejoZYi0nAD5o8vNltiOViQw6DZO7_byZz3Ut0/ALBNUaYAAAAAS_lusgPMAGmpPrg0BuNsJyymX-57ob4i/ HTTP/1.1 Host: photohuntservice.appspot.com Connection: keep-alive User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1064 Safari/532.5 Referer: http://photohuntservice.appspot.com/debug_newpuzzle?userToken=11001 Content-Length: 60360 Cache-Control: max-age=0 Origin: http://photohuntservice.appspot.com Content-Type: multipart/form-data; boundary=----WebKitFormBoundarybl05YLmLbFRf2MzN Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 ------WebKitFormBoundarybl05YLmLbFRf2MzN Content-Disposition: form-data; name="userToken" 11001 ------WebKitFormBoundarybl05YLmLbFRf2MzN Content-Disposition: form-data; name="img"; filename="Photo_020908_001.jpg" Content-Type: image/jpeg <image data> ------WebKitFormBoundarybl05YLmLbFRf2MzN Content-Disposition: form-data; name="longitude" -122.084095 ------WebKitFormBoundarybl05YLmLbFRf2MzN Content-Disposition: form-data; name="latitude" 37.422006 ------WebKitFormBoundarybl05YLmLbFRf2MzN-- This is the request from my client (which is written in Java on Android, but I don't think that's relevant): POST /_ah/upload/?userToken=11001/AMmfu6Zf9an6AU4lT9UuhIpxOZyOYb1LMwimFpeSh8zr6J1sX9F2ddJW3Qlsw0kwV3oALv-TNPWRQ6g4_Dgwk0UTwF47bbc78Yl44kDeV69MydTuR3N46S4/ALBNUaYAAAAAS_mMr3CYqTg3aVBDjhRxP0DyyRdvotyG/ HTTP/1.1 Content-Type: multipart/form-data;boundary=----WebKitFormBoundaryhdyNAhmOouRDGErG Cache-Control: max-age=0 Accept: */* Origin: http://photohuntservice.appspot.com Connection: keep-alive Referer: http://photohuntservice.appspot.com/getuploadurl?userToken=11001 Content-Length: 2638 Host: photohuntservice.appspot.com User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4) Expect: 100-Continue ------WebKitFormBoundaryhdyNAhmOouRDGErG Content-Disposition: form-data; name="userToken" 11001 ------WebKitFormBoundaryhdyNAhmOouRDGErG Content-Disposition: form-data; name="img";filename="PhotoHunt.jpg" Content-Type: image/jpeg <image data> ------WebKitFormBoundaryhdyNAhmOouRDGErG Content-Disposition: form-data; name="latitude" 37.422006 ------WebKitFormBoundaryhdyNAhmOouRDGErG Content-Disposition: form-data; name="longitude" -122.084095 ------WebKitFormBoundaryhdyNAhmOouRDGErG-- In both cases the AppEngine Python code to catch the request is the same: class UploadPuzzle( blobstore_handlers.BlobstoreUploadHandler ): def post(self): upload_files = self.get_uploads( ) The problem is that when running on the production AppEngine service self.get_uploads() returns an empty list when the request is made from my client app. Both requests return what I expect (a list with one blob_info in it) on the development server, and Chrome returns what I expect in both cases.

• Need to add totals of select list, and subtract if taken away

  - by jeremy

  This is the code I am using to calculate the sum of two values (example below) http://www.healthybrighton.co.uk/wse/node/1841 This works to a degree. It will add the two together but only if #edit-submitted-test is selected first, and even then it will show NaN until I select #edit-submitted-test-1. I want it to calculate the sum of the fields and show the amount live, i.e. the value of edit-submitted-test-1 will show 500, then if i select another field it will update to 1000. If i take one selection away it will then subtract it and will be back to 500. Any ideas would be helpful thanks! Drupal.behaviors.bookingForm = function (context) { // some debugging here, remove when you're finished console.log('[bookingForm] started.'); // get number of travelers and multiply it by 100 function recalculateTotal() { var count = $('#edit-submitted-test').val(); count = parseFloat( count ); var cost = $('#edit-submitted-test-1').val(); cost = parseFloat( cost ); $('#edit-submitted-total').val( count + cost ); } // run recalculateTotal every time user enters a new value var fieldCount = $('#edit-submitted-test'); var fieldCount = $('#edit-submitted-test-1'); fieldCount.change( recalculateTotal ); // etc ... }; EDIT This is all working beautiful, however I now want to add all the values together, and automatically update a total cost field that is the sum of a the added field with code above and field with value passed from previous page. I did this where accomcost is the field that is added together, but the total cost field does update, but not automatically, it is always one selection behind. i.e. If i select options and accomodation cost updates to £900, total cost remains empty. If i then change the selection and the accomodation updates to £300, the total cost updates to the previous selection of £900. Any help on this one Felix? ;) thanks. var accomcost = $('#edit-submitted-accomodation-cost').val(); accomcost = accomcost ? parseFloat(accomcost) : 0; var coursescost = $('#edit-submitted-courses-cost-2').val(); coursescost = coursescost ? parseFloat(coursescost) : 0; $('#edit-submitted-accomodation-cost').val( w1 + w2 + w3 + w4 + w5 + w6 + w7 + w8 + w9 + w10 + w11 + w12 + w13 + w14 + w15 + w16 + w17 + w18 + w19 + w20 + w21 + w22 + w23 + w24 + w25 + w26 + w27 + w28 + w29 + w30 ); $('#edit-submitted-total-cost').val( accomcost + coursescost ); var fieldCount = $('#edit-submitted-accomodation-cost, #edit-submitted-courses-cost-2') .change( recalculateTotal );

• Multi choice form field in Django

  - by Dingo

  Hi! I'am developing application on app-engine-path. I would like to make form with multichoice (acceptably languages for user). Code look like this: Language settings: settings.LANGUAGES = ((u"cs", u"Ceština"), (u"en", u"English")) Form model: class UserForm(forms.ModelForm): first_name = forms.CharField(max_length=100) last_name = forms.CharField(max_length=100) languages = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=settings.LANGUAGES) The form is rendered o.k. (all languages have checkbox. IDs, NAMEs is ok.) But if I save some languages for user, those languages don't check checkboxes. User model look like this class User(User): #... languages = db.StringListProperty() #... and view: def edit_profile(request): user = request.user if request.method == 'POST': form = UserForm(request.POST) if form.is_valid(): # ... else: form = UserForm(instance=user) data = {"user":user, "form": form} return render_to_response(request, 'user_profile/user_profile.html', data)

• Custom Display Form with Custom Workflow button

  - by Ifi

  I have created a new custom list form that will show 4 fields on the page from a Custom List called "Shipment". I have added Form Action button that I would like to run a custom action that is set inside of a Workflow. Currently, the form displays the fields for "Manifest Number", "Pickup Location", "Delivery Location", & "Scheduled Pickup Time". When the user clicks the Form Action button, what I want the Workflow to do is go to the ID field of the displayed content in the Form and change the value of the "Picked Up" column from No to Yes. The problem I am having is passing the ID of the displayed information from the Form to the Workflow as a variable. I can get the "Picked Up" column to update if I specify the value in the "Update List Item" window under the "Find the List Item" section, but I cannot figure out how to do this dynamically from the Form

• Which design pattern to manage windows?

  - by Lu Lu

  Hello, I am using .NET 2.0 & C# to develop a WinForm Mdi application. It will have a Main Window and a lot of mdi windows. I am thinking I should use which design pattern to manage mdi windows. Because I want only one instance for each window, if window is existed, I will show it on top, & otherwise I will create and show it. Note: a mdi window is opened from Menus of Main Window or open from another mdi window. An example is very good. Update: Menu's status is depended on mdi window's status. Ex: If Window 'A' is openned - menu 'A' - disabled. When window 'A' is closed - I update menu 'A' status to Enabled. Thanks.

• Does anyone have any EPiServer Exam Tips?

  - by gilles27

  Myself and some colleagues have just been told that we are all taking the EPiServer CMS certification exam on Friday. Having done some research on the web it does sound like a challenging exam - I've heard that only one in six people pass it. There doesn't seem to be much in the way of learning material, beyond what is described on the EPiServer site, this blog post and this blog post. Has anyone else out there passed recently and if so can they provide any hints or tips? Any help would be appreciated.

• How do I get ELMAH to work with SQL Server (permission problems)

  - by Gary McGill

  I've got ELMAH working on my (Cassini) development server, and was quite happy with it, but now that I'm trying to move everything to my production server (IIS7), the honeymoon looks like being over. I've got past the "gotcha" with IIS7, which frankly could have been better highlighted in the documentation, and if I just use the in-memory log then it works. However, I'm trying to get it to use the SQL Server log (as I do on my development system), and I'm getting an error along the lines of: The EXECUTE permission was denied on the object ELMAH_GetErrorsXml Well, fine. I know how to grant database permissions, but I'm really struggling to understand which user and which stored procs/tables I need to grant access to. The thing that's really confusing me is that I didn't have to do anything like this to get it to work on my development server. The only difference I can see is that on my development server it seems to connect as NT AUTHORITY\IUSR, whereas on my production server it seems to connect as NT AUTHORITY\NETWORK SERVICE. (It's just using a trusted connection so I've not explicitly configured it to do that - I presume it's to do with the web server). UPDATE: I've since established that because I'm using Cassini, it was actually logging in as me (an admin) and not IUSR, which explains why I didn't get any permission problems. On my development server, the IUSR account is a member of the public database role, and has access to the required database (again as "public"). There's no explicit granting of object-level permissions. [See update above - this is irrelevant]. On my production server, I've added NETWORK SERVICE in exactly the same way (public database role, explicit access to the database as "public"). Yet, I get this permission error. Why?!! [See update above - the only reason I don't get a permission error is because I'm running as an admin]. And, of course, if the fact that it works locally is just "luck", I will need to know which SPs/tables to grant access to. My guess would be all 3 SPs and not the table, but it would be good (again) to see some documentation that makes this explicit.

• Highlighting effect to text and/or image similar to be synchronized with audio

  - by Irfan Mulic

  I am looking how to approach following problem: We have application that displays text with audio recorded material. We use Browser Control (Internet Explorer) in Delphi App to do this. We respond to events in Delphi code setting innerHTML for elements if we have to update the style ... Now, request is to add option to dynamically move the cursor or dynamically highlight the words spoken from the paragraph. It doesn't need to match absolutely the exact word spoken so we will have to dynamically update the content of position of highlighted word based on some timer or something (because it is not text to speach). What should be the most practical and easy approach to this kind of problem, all answers are greatly appreciated. Thanks.

• Validating only selected fields using ASP.NET MVC 2 and Data Annotations

  - by thinknow

  I'm using Data Annotations with ASP.NET MVC 2 as demonstrated in this post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx Everything works fine when creating / updating an entity where all required property values are specified in the form and valid. However, what if I only want to update some of the fields? For example, let's say I have an Account entity with 20 fields, but I only want to update Username and Password? ModelState.IsValid validates against all the properties, regardless of whether they are referenced in the submitted form. How can I get it to validate only the fields that are referenced in the form?
