• Getting content of a Facebook page in Adobe Flex

  - by cuneyt

  Hi guys, I wrote a Flex application that sends a UrlRequest to Facebook and gets the content of page as a string. The application user clicks a button, and the application connects to Facebook. And no I do not mean using Facebook API. It is like a screen scraper. This application worked locally, but when deployed to server it gives a sandbox security error. I have my crossdomain.xml on the root, but I think the problem is not that. Not only Facebook, but I cannot get any web site when the application is deployed on server. What should I do to get the content of a remote web page?

• Compare a DateTime to the current date

  - by looloobs

  Hi I am trying to use a condition on events when the start_at DateTime is equal to or greater than Today's date. I want to list upcoming events, but clearly they are not upcoming if they have already passed. I have: @appointments = Event.find(:all, :conditions => ['move_id = ? AND start_at = ?', @move.id, Date.today]) I think I may be comparing apples and oranges here. It doesn't throw and error, just doesn't do what it is supposed to. Help! Thanks in advance.

• SQL Drop Index on different Database

  - by Jim

  While trying to optimize SQL scripts, I was recommended to add indexes. What is the easiest way to specify what Database the index should be on? IF EXISTS (SELECT * FROM sysindexes WHERE NAME = 'idx_TableA') DROP INDEX TableA.idx_TableA IF EXISTS (SELECT * FROM sysindexes WHERE NAME = 'idx_TableB') DROP INDEX TableB.idx_TableB In the code aboce, TableA is in DB-A, and TableB is in DB-B. I get the following error when I change DROP INDEX TableA.idx_TableA to DROP INDEX DB-A.dbo.TableA.idx_TableA Msg 166, Level 15, State 1, Line 2 'DROP INDEX' does not allow specifying the database name as a prefix to the object name. Any thoughts are appreciated.

• When designing an event, is it a good idea to prevent listeners from being added twice?

  - by Matt

  I am creating an event-based API where a user can subscribe to an event by adding listener objects (as is common in Java or C#). When the event is raised, all subscribed listeners are invoked with the event information. I initially decided to prevent adding an event listener more than once. If a listener is added that already exists in the listener collection, it is not added again. However, after thinking about it some more, it doesn't seem that most event-based structures actually prevent this. Was my initial instinct wrong? I'm not sure which way to go here. I guess I thought that preventing addition of an existing listener would help to avoid a common programming error. Then again, it could also hide a bug that would lead to code being run multiple times when it shouldn't.

• How to do insert one row from one table to another table(what has less columns)?

  - by chobo2

  Hi I am trying to find rows that are not in one table and insert them into another. The table I am trying to insert into has less columns then the other one. These columns are null but it would be cool if I could hardcode a value before I do the insert. But I am having so much trouble with just trying to get it to insert. I have something like this SELECT p.ProductId, p.ProductName INTO SomeTable FROM Product as p WHERE p.ProductName != 'iPad' I will get a error like this though Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "p.ProductId" could not be bound. I am not sure what I am doing wrong. I copied and pasted the names in so I don't think it is a spelling mistake. I am using ms sql 2005 express.

• How to disable typing in values in Dojo's NumberSpinner?

  - by callie16

  Hi, is there a way to disable typing in of values in the NumberSpinner of Dojo? Or is there a way for me to set back a previous value to it? Here's a sample situation: I have a spinner where the range is 1-3. However, the user types in an invalid value... say, a letter. The usual error handling happens. However, if the user deletes the value and focuses out (e.g. goes to another widget/control/etc. in the page), the spinner stays blank. Either I reset it to the last valid value or I disable typing so that the user can just use the up and down arrows to manipulate the widget. Any thoughts? Thanks!

• Can't search in a certain field using solR

  - by intrance

  Hi, I'm setting up an environment using Nutch 1.0 + solR 1.4. In Nutch I configured the subcollection plugin which seems to work nicely. If I search as normal adding fl=* I can see the subcollection field is filled as intented. (something like <str name="subcollection">mysite.com</str>). My problem is, I would like to be able to search only in one or more given subcollections, but whenever my searchquery is something like q=subcollection:mysite.com it won't work. I've also tried to add a fl=* or searched in mysite* instead but I never get any results. Obviously solR "knows" the subcollection field, as it doesn't result with an error but simply whith an empty result. I'd be glad for any help

• Website/App on Dotcloud is down

  - by user1576866

  The website is nhslhs.tk . The last time I edited something was four days ago. I tried to get a calendar on the Django datable, but deleted it all and never actually pushed it to the Dotcloud server. Also, few hours before that I was able to update HTML files, push them, and see the edits on the website. The link should take you to a log-in page (this is available when you google "nhslhs.tk" and click cache view) but it takes you to a search magnified advertisement-esque page. On a few sites, people claimed the error was due to a Trojan horse virus or server being down. Do you know how to fix this? Thanks!

• Getting service unavailable message when sending messages to google xmpp using wokkel

  - by Code freak

  Hi, I made a wokkel (twisted python) bot to send and receive messages from the google xmpp service. Everything (auth, presence) etc works fine. One of the rquirements of our prject is that we need to send broadcast messages to everyone in the list. Normal messages and replies work fin, but when i snd a broadcast message, i get this service unavailable error 503 message. There are about 1000 user in my contact list. Is this some bug in the code or is it google policy to prevent rapid messaging. Also, how do other google bots cater to a large contact base ? does google provide a commercial solution for such applications ? Thanks

• Unable to bind in asp.net grid Template Column

  - by OneSmartGuy

  I am having trouble accessing the data field. I receive the error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. I can get the value but using <%# getOpenJobs((string)Eval("ParentPart")) % but I need to use it in the if to display a certian picture if it passes the condition. Is there a better way to do this or am i just missing something simple? <telerik:GridTemplateColumn UniqueName="hasOpenJobs" HeaderText=""> <ItemTemplate> <% if (getOpenJobs((string)Eval("ParentPart")) > 1) { %> <img src="../images/job-icon.gif" alt="Open Jobs" /> <%} %> </ItemTemplate> </telerik:GridTemplateColumn>

• Is it possible to place Joomla under revision control?

  - by Tom

  We are a team of many developers working on a website that uses both Joomla and custom PHP scripts. The problem is that there are multiple developers working on various features which need to update information in Joomla (adding modules, changing existing ones or changing settings) and when one developer changes something, he usually makes the change locally first and then does the same thing (hopefully) on the production server. Not only that this is very error-prone, but the developers often forget to tell other developers about the changes. The custom PHP scripts are easily shared between developers, but the changes in Joomla are often forgotten and they lead to serious conflicts when a developer tries to replicate his local changes in production. I have thought about placing Joomla in a Mercurial repository, but how could we distribute the changes in the database between the development, the testing and the production machines?

• How to port C# code which uses a callback to VB.NET?

  - by Bob

  I need to port the following from the ASP.NET MVC 2 sourcecode from C# to VB.NET. It's from AuthorizeAttribute.cs beginning on line 86: HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache; cachePolicy.SetProxyMaxAge(new TimeSpan(0)); cachePolicy.AddValidationCallback(CacheValidateHandler, null /* data */); where CacheValidateHandler is: private void CacheValidateHandler(HttpContext context, object data, ref HttpValidationStatus validationStatus) { validationStatus = OnCacheAuthorization(new HttpContextWrapper(context)); } The VB.NET port from http://converter.telerik.com doesn't quite work for this line: cachePolicy.AddValidationCallback(CacheValidateHandler, Nothing) ' Error where CacheValidateHandler is: Private Sub CacheValidateHandler(ByVal context As HttpContext, ByVal data As Object, _ ByRef validationStatus As HttpValidationStatus) validationStatus = OnCacheAuthorization(New HttpContextWrapper(context)) End Sub VS2008 complains that CacheValidateHandler does not specify its arguments for context, data, and validationStatus. Any ideas how to port this code?

• FTP .NET Sockets

  - by Jojo

  Hi Everyone, I have an FTP auto downloader program. It downloads new files from a given FTP folder. The application was successful for some FTP folders that i have tested. These folders contain 30 - 50 files. However, when i tried an FTP folder with 150 and 18000 files, i receive this error message: An established connection was aborted by the software in your host machine. My first assumptions will be because of firewalls or anti virus. I don't have administrative access to this computer so I would like to ask if there are other reasons for this before i raise this to our systems dept? Need anyone's help asap. Thanks :)

• how many dojo fliteringselect can I have on a form?

  - by Grant Collins

  I have a quick question How many dojo filteringselects can I have on a form? I have a form with 2 filteringselects on it, both getting data from different json datastores to populate the values. However only the first filteringselect is being populated, the other grabs no data. I am using Zend Framework and Zend_Dojo_Form to create the form elements for this. Many thanks. Ok looks like my code is broken somewhere then. The element that is failing in my form is: $location = new Zend_Dojo_Form_Element_FilteringSelect('location'); $location->setAutocomplete(true) ->setStoreId('countiesstore') ->setStoreType('dojo.data.ItemFileReadStore') ->setStoreParams(array('url' => $baseUrl.'/dojo/counties')) ->setAttrib('searchAttr', 'title') ->setRequired(true) ->removeDecorator('DtDdWrapper') ->removeDecorator('label') ->removeDecorator('HtmlTag') ->removeDecorator('Error'); When I go to http://localhost/dojo/counties I get the json file to read, but the element isn't populated with any data. Any ideas?

• ASP.NET Custom Control With A Property That Is An Interface

  - by user129674

  I want to have a property on my custom control that is an interface type. For example: [ ToolboxData("<{0}:MyTextBox runat=server></{0}:MyTextBox"), ParseChildren(true, "Validation") ] class MyTextBox : WebControl { [ Category("Behavior"), Description("The validation to use"), DesignerSerializationVisibility(DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerDefaultProperty) ] public IValidation Validation { get; set; } } Then when I go to use my control in a web form I would like to be able to do: <my:MyTextBox ID="txt" runat="server"> <my:FancyValidator /> </my:MyTextBox> That way I will be able to define one class that could use any number of validators. When I try and do this now, I end up with an error saying: Type 'IValidator' does not have a public property named 'FancyValidator' What do I need to do to make this work? Thanks!

• Reading in a file - Warning Message in R

  - by Sheila

  I have a file that has 22268 rows BY 2521 columns. When I try to read in the file using this line of code: file <- read.table(textfile, skip=2, header=TRUE, sep="\t", fill=TRUE, blank.lines.skip=FALSE) I get the following error: Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : number of items read is not a multiple of the number of columns I also used this command to see what rows had an incorrect number of columns: x <-count.fields("train.gct", sep="\t", skip=2) which(x != 2521) and got back a list of about 20 rows that were incorrect. Is there a way to fill these rows with NA values? I thought that is what the "fill" parameter does in the read.table function, but it doesn't appear so. Any help would be greatly appreciated. Thank you.

• Display graph without saving using pydot

  - by user506710

  Hello all I am trying to display a simple graph using pydot. My question is that is there any way to display the graph without writing it to a file as currently I use write function to first draw and then have to use the Image module to show the files. However is there any way that the graph directly gets printed on the screen without being saved ?? Also as an update I would like to ask in this same question that I observe that while the image gets saved very quickly when I use the show command of the Image module it takes noticeable time for the image to be seen .... Also sometimes I get the error that the image could'nt be opened because it was either deleted or saved in unavailable location which is not correct as I am saving it at my Desktop..... Does anyone know what's happening and is there a faster way to get the image loaded..... Thanks a lot....
