• JQuery Validation using Remote posts empty data to webservice

  - by user319721

  I'm using the JQuery Validation plugin. I'm using the remote option to make a call to my webservice to check if a company name exists. The webservice only accepts JSON data. I pass the data to the webservice from the Company Input Field in my Form as follows: data: "{'company': '" + $('#Company').val() + "'}" But this always returns a blank value for company so the response is {'company':''} i.e. correct JSON but missing the Company Input Field value. Can anyone shed some light on why I always get a blank value here? Thanks for the help, Ciaran

• Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?!

  - by Ahmed

  Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?! As, I'm working on a website, which uses SAP .NET connector. I already added a reference for connector ddl, and while referencing its namespace "using namespace_name", or set class namespace to another one rather than connector namespace, I got error regarding connector classes with that error message "The type or namespace couldn't be found, are you missing a using directive or an assembly reference?". But while changing namespace name to connector namespace, everything is going well?! // Set namespace to be IDestinationConfiguration interface namespace. namespace SAP.Middleware.Connector { public class ConnectorConfiguration : IDestinationConfiguration { } } So, connector types forced me to set namespace of class to their namespace! Is this possible? If so, how?

• Using lock(obj) inside a recursive call

  - by Amby

  As per my understanding a lock is not released until the runtime completes the code block of the lock(obj) ( because when the block completes it calls Monitor.Exit(obj). With this understanding i am not able to understand the reason behind the behaviour of the following code. private static string obj = ""; private static void RecurseSome(int number) { Console.WriteLine(number); lock (obj) { RecurseSome(++number); } } //Call: RecurseSome(0) //Output: 0 1 2 3...... stack overflow exception There must be some concept that i am missing. Please help.

• Reduce Heroku Compiled Slug Size

  - by etrepat

  I've just updated rails to v2.3.6 on my app under a bamboo-ree-1.8.7 stack and the compiled slug size has grown up to 40.5Mb! Previous to that last git push, the slug size was about 20Mb and was using rails v2.3.5. Is it because my slug has both of rails versions installed? Probably I'm missing something but I haven't added any special code/files into my app as to increase the slug size by ~20Mb. Can you point me on how can I reduce the slug size? Any help will be greatly appreciated. Thank you very much in advance.

• Swiz mandates weak encapsulation.

  - by Faisal

  I just started using Swiz, and, it seems like Swiz forces you to create classes with weak encapsulation. Swiz requires all event handlers to be public in order to mediate events. Assume that component 'A' dispatches a few events, which I want to listen to in component 'B'. Traditionally, I'll just add event listeners on 'A' in 'B' and all the event handlers in 'B' can be kept private. However, if, I am using Swiz, I need to make all the handlers, mediating events, public. Am I missing something here, is there a way to bypass this problem. I really, don't want to pollute the public interface of my class. Thanks.

• vs2008 attach to process, can't see which process

  - by Mafti

  Hi, In vs2003 (and vs2005(not sure about that)) when I attached to a process, before actually attaching I could see which process were running under w3wp (I have a couple of websites running locally) so I knew which exact .net application I was about to debug. however in vs2008 the window doesn't show up anymore.. now I have to attach it, come to the conclusion it was the wrong process, stop debugging and attach it to the other process (if I haven't forgot teh processid :P ) Is there a way to "enable" that interesting window to see with .net apps are runnig in that specific w3wp process? or am i missing something obvious?

• App Engine remote_api with OpenID

  - by hawkettc

  Hi, I've recently tried to switch my app engine app to using openID, but I'm having an issue authenticating with remote_api. The old authentication mechanism for remote_api doesn't seem to work (which makes sense) - I'm getting a 'urllib2.HTTPError: HTTP Error 302: Found', which I assume is appengine redirecting me to the openid login page I've set up. I guess I'm missing something fairly obvious. Currently my remote_api script has the following in it - remote_api_stub.ConfigureRemoteDatastore(app_id=app_id, path='/remote_api', auth_func=auth_func, servername=host, secure=secure) where auth_func is def auth_func(): return raw_input('Username:'), getpass.getpass('Password:') Any ideas what I need to supply to remote_api? I guess similar issues would be encountered with bulkloader too. Cheers, Colin

• Permissions error for a signed Java applet when including external JAR files

  - by sri

  I have a signed Java applet. And it works fine. But now I have to integrate some 3rd party JAR files with it. When I test it from Eclipse, the whole thing works correctly. But when I test it as an applet, it gives me a FilePermission error. I thought this was because those 3rd party JAR files don't have a java.policy.applet within them. But manually adding the policy file doesn't get rid of the error. What am I missing? Thanks! ============================ All the 3rd party JAR files sit on the server filesystem like so: A.jar, B.jar, C.jar. And I include them in the applet tag like so: <applet archive="my.jar,A.jar,B.jar,C.jar"> </applet> Also, in the MANIFEST/MANIFEST.MF file in my.jar, I include those JAR files like so: Class-Path: A.jar,B.jar,C.jar

• Whats the python way for recursively setting file permissions?

  - by Geoff

  What's the "python way" to recursively set the owner and group to files in a directory? I could just pass a 'chown -R' command to shell, but I feel like I'm missing something obvious. I'm mucking about with this: import os path = "/tmp/foo" for root, dirs, files in os.walk(path): for momo in dirs: os.chown(momo, 502, 20) This seems to work for setting the directory, but fails when applied to files. I suspect the files are not getting the whole path, so chown fails since it can't find the files. The error is: 'OSError: [Errno 2] No such file or directory: 'foo.html' What am I overlooking here?

• Copying a 2D non-space array to another

  - by Jay

  I'm a total programming newb who started learning java programming this sem at uni. I'm up to a step where i need to copy some elements from one method to another. This program i'm creating is called an L_Game. The question I'm stuck is: the project(Slide other) method should take another slide as a parameter, and copy each non-space cell from this slide into the other slide (i.e. like a projector projecting slides onto a screen. I previously made a constructor with the parameter cells in it and believe i copied it to the project(Slide other) method. But i'm not sure what to do to copy each "non-space cell" With the "for" method or the "if" method? If my question isn't typed correctly or have information missing, please let me know. Any help will be appreciated. (I obviously have no idea with what i'm doing...)

• How do I build a DataTemplate in c# code?

  I am trying to build a dropdown list for a winform interop, and I am building the dropdown in code. However, I am having a problem getting the data to bind based on the DataTemplate I specify.

• How do i change the Scala version that sbt works with?

  - by ashy_32bit

  Firing up the SBT console it reads : [info] Building project AYLIEN 1.0 against Scala 2.8.1 [info] using MyProject with sbt 0.7.4 and Scala 2.7.7 How can I make it use MyProject with sbt 0.7.4 and Scala 2.8.1 ? Please pay attenetion that I'm not asking about the Scala version that is used to build my project (it is the 2.8.1 as you can see), but I rather want to make sbt use MyProject with Scala 2.8.1. Apparently sbt uses it's own scala version to work with project definition (MyProject here) which is different than one it uses to actually build the project! or perhaps I'm missing something ... ?

• In C, as free() knows an array size, why isn't there a function that gets the array size? [closed]

  - by user354959

  Possible Duplicate: If free() knows the length of my array, why can’t I ask for it in my own code? Searching around (including here at stackoverflow), I got that malloc() allocates an array and also creates a header to control the array info. In this header, there's also the array size. free() use such information to know how to deallocate that array. So, if the array size info is "there" (somewhere in the memory), why there isn't a function that returns an array size, looking for this at the array header? Or am I missing something?

• mysql replace matching but not changing

  - by alex

  I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work-it matches the rows, but doesn't replace. Here's what I'm trying to do: mysql> update contained_widgets set preference_values = replace(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

• How to access a website's url programmatically from within the page

  - by Jeff

  For work, I am working on a site that has a feature that lets users make custom instances of the site depending on who they want to show it to. So if they want to show their potential employer a little bit about themselves, they can send them a custom url, that has a uid on the end of it that tells the database what to show and what not to when the site is loaded up. Now, I need to be able to take the value that is on the end of the url, this unique uid that corresponds with their preferences in the db, accessable on run time. Meaning that when someone types in this custom url, I need to be able to show the name of the person whose portfolio is being viewed BEFORE password authentication takes place... If I could get the URL, I suppose I could parse through it to find the necessary UID...but how do I get the url? Maybe I am just missing something here, but if anyone has any thoughts or ideas, it would be appreciated!! Thanks

• Simulating brush strokes for painting application

  - by DrRobot

  I'm trying to write an application that can be used to create pictures that look like paintings using simulated brush strokes. Are there any good sources for simple ways of simulating brush strokes? For example, given a list of mouse positions that the user has dragged the mouse through, a brush width and a brush texture, how do I determine what to draw to the canvas? I've tried angling the brush texture in the direction of the mouse movement and dabbing several brush texture images along the path, but it doesn't look great. I think I'm missing something where the brush texture should shrink and grow on corners. Any simple to follow links would be appreciated. I've found complex academic papers on simulating e.g. oil paints but I just want a basic algorithm to use that produces OK results if possible.

• using C# how to convert iso8859-1 encoded text files that contain Latin-1 accented characters to utf

  - by Tim

  I am being sent text files saved in iso88591-1 format that contain accented characters from the Latin-1 range (as well as normal ASCII a-z etc). How to convert these files to utf-8 using C# so that the single-byte accented characters in iso8859-1 become valid utf-8 characters? I have tried to use a StreamReader with ASCIIEncoding, and then converting the ascii string to UTF-8 by instantiating an ascii encoding and a utf8 encoding and then using Encoding.Convert(ascii, utf8, ascii.GetBytes( asciiString) ) — but the accented characters are being rendered as question marks. What step am I missing? Thanks

• How do I specify a null relation in SQLAlchemy?

  - by Jesse

  Not sure what the correct title for this question should be. I have the following schema: Matters have a one-many relationship to WorkItems. WorkItems have a one-one (or one-zero) relationship to LineItems. I am trying to create the following relation between Matters and WorkItems Matter.unbilled_work_items = orm.relation(WorkItem, primaryjoin = (Matter.id == WorkItem.matter_id) and (WorkItem.line_item_id == None), foreign_keys = [WorkItem.matter_id, WorkItem.line_item_id], viewonly=True ) This throws: AttributeError: '_Null' object has no attribute 'table' That seems to be saying that the second clause in the primaryjoin returns an object of type _Null, but it seems to be expecting something with a "table" attribute. This seems like it should be pretty straightforward to me, am I missing something obvious?

• How to connect to a legacy Informix database?

  - by ivo

  I have to connect my app to a customer's Informix 7.2 legacy database. From what I was able to find out, in theory there should be a database service running on port 50000. The problem is that I cannot find any database service in the Operative System. So far I'm only able to use dbaccess and perform queries from the command line. I would like to use a database driver (such as http://code.google.com/p/ibm-db/) so my app can connect and query the database using a cursor, but since I cannot find any database service, apparently I can't... Am I missing something here? Are there options I'm not considering? Is it possible to have an Informix database in which the only interface is dbaccess?

• Is there simple way to play an rtp video/audio stream in WPF?

  - by Robin

  I need to create a WPF control that will play an rtp stream with the requirement that the latency needs to be as low as possible. I've looked at the following two projects: http://vlcdotnet.codeplex.com/ http://wpfmediakit.codeplex.com/ As far as I know, I can't use VLC because we're shipping a commercial application with a more restrictive license than GPL (i.e. we can't ship our source). Wpf media kit is nice, but I can't seem to find a good/free rtp directshow source filter and I wanted to ask if there is a simpler solution out there that I'm missing before I jump into writing my own. Any ideas?
