• insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

• Mootools not loading fast enough IE6

  - by Tom

  Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom

• Is the single <form runat="server">-element requirement really necessary for ASP.NET WebForms?

  - by michielvoo

  Looking at some of the changes coming to WebForms in ASP.NET 4.0 I can see many improvements that give developers even more control over the output. Some of these improvement have been a long time coming, and for some time it seemed that it wasn't even possible. It made me wonder if the current model with the single form element that runs on the server is really the only possible way. Why couldn't the ASPNET WebForm architecture work with multiple forms that all run on the server? Imagine if you could architect this change. How would it impact the way we write codebehind today? Would it introduce extra complexity? Would it change the way event handlers work, or validation, or ASP.NET Ajax with the ScriptManager and UpdatePanel controls?

• Get Hardware Information for HWs that is not installed

  - by Isaac

  I am pretty sure how to retrieve hardware information with WMI classes. but WMIs have a big limitation: They Just can get information for installed hardwares. I need to retrieve information about CPU (model,speed,etc..),Video Card, Sound Card, USB Ports, etc. I found a really good software (HWiNFO) that can do this even the drivers for hardware parts is not installed. It seems that HWiNFO uses a internal database to give a name for each hardware part. So is there any free library/DLL/component that can do this in Windows XP or higher Note: Although HWiNFO SDK seems good, it's not free. So it doesn't exist! ;) I need a free library.

• software/languages for online structured data collection from (human) clients

  - by Ben

  I need to develop a web interface to collect and validate a range of data from many of my organization's clients. This isn't a single form, but a collection of forms with interdependencies (i.e., field X on form Y is needed if field A was equal to C on form B), and variable length lists (please provide the details for all Xs in your possession). I had a look at the marketing on Microsoft InfoPath and Adobe LiveCycle, but I get the impression that they're principally electronic forms solutions rather than data collection tools. (e.g., If a user has entered their address once, they should never have to see it on a form again). Any suggestions of good tools, applications or domain-specific languages?

• Extending Django-tagging, adding extra field to each tag?

  - by victorhooi

  heya, We're coding together a Django app to handle reviews of newspaper articles. Each newspaper article model will an arbitrary number of tags associated with it. Also, each tag will have an optional ranking (0 to 10). I was thinking of using django-tagging to do this (http://code.google.com/p/django-tagging/), but I'm not sure of the best way to add the ranking to the system. Should I extend django-tagging somehow? (Not sure if this is possible, without changing django-tagging's actual code?). Or is there a better way of achieving this? Cheers, Victor

• Google Analytics Widget Tracking

  - by Kevin Lamb

  Hello, I have a form that is generated on a customer's website (lets say customer.com) with javascript that a user fills out and it sends to my site (app.com). I would like to be able to provide information to the customer such as how effective their AdWords campaign was and what search engines users used to end up filling out the form. I have started looking at the multiple domain linking option but I am not sure this is the right way. Is there a way to query what search engine and key words they used and pass this along with the form?

• Using the ASP.NET membership provider database with your own database?

  - by Shaharyar

  Hello everybody, We are developing an ASP.NET MVC Application that currently uses it's own databse ApplicationData for the domain models and another one Membership for the user management / membership provider. We do access restrictions using data-annotations in our controllers. [Authorize(Roles = "administrators, managers")] This worked great for simple use cases. As we are scaling our application our customer wants to restrict specific users to access specific areas of our ApplicationData database. Each of our products contains a foreign key referring to the region the product was assembled in. A user story would be: Users in the role NewYorkManagers should only be able to edit / see products that are assembled in New York. We created a placeholder table UserRightsRegions that contains the UserId and the RegionId. How can I link both the ApplicationData and the Membership databases in order to work properly / having cross-database-key-references? (Is something like this even possible?) All help is more than appreciated!

• Sync GIT and ClearCase

  - by Senthil A Kumar

  I am currently working on ClearCase and now migrating to GIT. But we need this migration in a way that all work will be done in GIT and the data will be synced backed to ClearCase stream. We will have the same branch names and stream names in both GIT and CC, so scripting shouldn't be a problem. The problem here is, Can someone suggest which is the best model to sync CC and GIT Have all the Vobs in CC as single repo in GIT, and have the major stream in CC as various branches in GIT. - Single GIT repo (VOBS) and many branches (CC streams). - This takes up less space as VOBs are kept as single repo with many branches. Have important CC branches as independent GIT repositories and each repository having all the CC VOBs. - Many GIT repo for many CC branch - This will take up lots of space as VOBs will be replicated across. Which do you think is the best way to keep it in sync with ClearCase

• Why is there a limit of max 20 parameters to a clojure function

  - by GuyC

  Hi, there seems to be a limit to the number of parameters a clojure function can take. When defining a function with more than 20 parameters I receive the following: Obviously this can be avoided, but I was hitting this limit porting the execution model of an existing DSL to clojure, and I have constructs in my DSL like the following, which by macro expansion can be mapped to functions quite easily except for this limit: (defAlias nn1 ((element ?e1) (element ?e2)) number "@doc features of the elements are calculated for entry into the first neural network, the result is the score computed by the latter" (nn1-recall (nn1-feature00 ?e1 ?e2) (nn1-feature01 ?e1 ?e2) ... (nn1-feature89 ?e1 ?e2))) which is a DSL statement to call a neural network with 90 input nodes. Can work around it of course, but was wondering where the limit comes from. Thanks.

• qtableview (libqt) how do I correctly create a QModelIndex

  - by Chris Camacho

  I'm trying to enter edit mode on a specific cell like this void MainWindow::on_addButton_released(void) { tm->addRow(); tableView->scrollToBottom(); int ec=tm->firstWritableColumn(); int r=tm->rowCount(QModelIndex()); QModelIndex id = tm->index(r, ec, QModelIndex()); tableView->setCurrentIndex(id); tableView->edit(id); qDebug() << "row:" << r << " col:" << ec << "index:" << id; } my model creates an index like this QModelIndex TableModel::index(int row,int column,QModelIndex parent) const { Q_UNUSED(parent); return createIndex(row,column,0); } the debug output looks like this row: 9 col: 1 index: QModelIndex(9,1,0x0,TableModel(0xbf3f50) ) I'm fairly sure that the index is somehow invalid as setCurrentIndex doesn't seem to be working

• Unable to save to wincache from cakePHP shell

  - by Phillaf

  I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

• Convert data retrieved from MySQL database into JSON object using Python/Django

  - by rohanbk

  I have a MySQL database called People which contains the following schema <id,name,foodchoice1,foodchoice2>. The database contains a list of people and the two choices of food they wish to have at a party (for example). I want to create some kind of Python web-service that will output a JSON object. An example of output should be like: { "guestlist": [ {"id":1,"name":"Bob","choice1":"chicken","choice2":"pasta"},{"id":2,"name":"Alice","choice1":"pasta","choice2":"chicken"} ], "partyname": "My awesome party", "day": "1", "month": "June", "2010": "null" } Basically every guest is stored into a dictionary 'guestlist' along with their choices of food. At the end of the JSON object is just some additional information that only needs to be mentioned once. The question that I have is regarding the method that I need to utilize to grab the data from my database, and create the JSON object. Do I need to use a standard Model/View structure of Django or can I get away with something that is much simpler since what I need to do is really simple?

• Rails show latest entry

  - by Danny McClelland

  Hi Everyone, I have a working Rails application on version 2.3.5 - I am using many to many model relations and have got almost everything working. What I would like to do is on my new kase page show the most recent kase job ref at the top. So for example, if I created a new kase with a job ref of "001", if I then went to create a new kase it would show at the top "Your previous kases reference was 001". I have the field of jobref in the new kase form, so I am trying to workout what I need to do to output only the last jobref. If that makes sense! Thanks, Danny

• Separation of concerns and authentication

  - by Tom Gilder

  I'm trying to be a Good Developer and separate my concerns out. I've got an ASP.NET MVC project with all my web code, and a DAL project with all the model code. Sometimes code in the DAL needs to check if the current user is authorized to perform some actions, by checking something like CurrentUser.IsAdmin. For the web site, the current is derived from the Windows username (from HttpContext.Current.User.Identity), but this is clearly a web concern and shouldn't be coupled to the DAL. What's the best pattern to loosely couple the authentication? Should the DAL be asking the MVC code for a username, or the MVC be telling the DAL? Are there advantages or disadvantages to one or the other? Thank you!

• Javascript back button for iframe parent window

  - by DisgruntledGoat

  I have some pages with iframes in them. I want to add a link/button inside the iframe, to make the browser go back one page in history. But I want the PARENT to go back, not the iframe itself. I originally had this, which makes the iframe page go back (if it exists): <a href="javascript:history.back()">&laquo; Go back</a> I've tried window.parent.history.back() and window.parent.document.history.back() but neither one works. There are no cross-domain issues accessing the iframe from the parent and vice-versa.

• WSDL for other protocols different than SOAP?

  - by SDReyes

  From wikipedia: The Web Services Description Language (WSDL, pronounced 'wiz-d?l') is an XML-based language that provides a model for describing Web services. But in most cases, I found that WSDL is used in conjunction with SOAP. but as far as I know, if the WSDL is a language to describe web services. there should be possible to describe another kind of web services different from SOAP. is this possible? any examples? Thanks!

• How to run report in ReportViewer without having to click View Report button?

  I've set up my report with params and it's value. When I run the page, it wants me to click the View Report button, but I need it to just run instead of interacting. Any ideas on this?

• Star-schema: Separate dimensions for clients and non-clients or shared dimension for attendants?

  - by celopes

  I'm new to modeling star schemas, fresh from reading the Data Warehouse Toolkit. I have a business process that has clients and non-clients calling into conference calls with some of our employees. My fact table, call it "Audience", will contain a measure of how long an attending person was connected to the call, and the cost per minute of this person's connection to the call. The grain is "individual connection to the conference call". Should I use my conformed Client dimension and create a non-client dimension (for the callers that are not yet clients) this way (omitting dimensions that are not part of this questions): Or would it be OK/better to have a non-conformed Attending dimension related to the conformed Client dimension in this manner: Or is there a better/standard mechanism to model business processes like this one?

• Adding custom context menu items to an Outlook MailItem using Outlook 2007 VSTO 3.0

  - by cbass

  Hi I've been trying to figure out how to create a context menu in VSTO 2007. I'm hoping that is possible. When I make this call. Dim commandBar As Microsoft.Office.Core.CommandBar = _word.CommandBars("Text") I get the following error. This object model command is not available in e-mail. I've look all over and from what I can tell it's not possible to add to the context menu in Office 2007. This doesn't seem right. I've also tried this event without any luck since it isn't being fired when right clicking on the MailItem ItemContextMenuDisplay(ByVal commandBar As Microsoft.Office.Core.CommandBar, ByVal selection As Microsoft.Office.Interop.Outlook.Selection) Hoping that someone can help. Thanks in advance.
