• How can I prevent Telerik RadChart from generating an onerror attribute?

  - by Sean McMillan

  We're using the Telerik Rad Controls for ASP.Net Ajax on an ASP.Net MVC project. The RadChart generates the following HTML: <img onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" src="ChartImage.axd?UseSession=true&amp;ChartID=e25ad666-e05b-4a92-ac0c-4f2c729b9382_chart_ctl00$MainContent$AverageCTMChart&amp;imageFormat=Png&amp;random=0.501658702968461" usemap="#imctl00_MainContent_AverageCTMChart" style="border-width: 0px;" alt=""> I'd like to remove the onerror attribute; I don't really want the customers being offered the option to see a stack trace if something goes wrong. I can't see any way to control the markup that this control generates. Google searches provide no help. Has anyone dealt with this before? How do I remove the onerror attribute?

• Seeking enlightenment - global variables in AppEngine (aeoid.get_current_user())

  - by jerd

  Hello This may be a 'Python Web Programming 101' question, but I'm confused about some code in the aeoid project (http://github.com/Arachnid/aeoid). here's the code: _current_user = None def get_current_user(): """Returns the currently logged in user, or None if no user is logged in.""" global _current_user if not _current_user and 'aeoid.user' in os.environ: _current_user = User(None, _from_model_key=os.environ['aeoid.user']) return _current_user But my understanding was that global variables were, ehm, global! And so different requests from different users could (potentially) access and update the same value, hence the need for sessions, in order to store per-user, non-global variables. So, in the code above, what prevents one request from believing the current user is the user set by another request? Sorry if this is basic, it's just not how i thought things worked. Thanks

• How to determine MS Access field size via OleDb

  - by Andy

  The existing application is in C#. During startup the application calls a virtual method to make changes to the database (for example a new revision may need to calculate a new field or something). An open OleDb connection is passed into the method. I need to change a field width. The ALTER TABLE statement is working fine. But I would like to avoid executing the ALTER TABLE statement if the field is already the appropriate size. Is there a way to determine the size of an MS Access field using the same OleDb connection?

• What's viewport mean to the jQuery guys?

  - by justSteve

  I came here intent on asking a 'how do i' type question focused on a particular UI problem i have to solve and i started using the term 'viewport'. Seems there's lots of contexts that tag evokes. Before i outline mine i should ask - is there a generally recognized consensus as to what a 'viewport' is? Any gallery or object browser that focuses on a UI principle where multiple frames/panes show feeds of different graphs where each feed might be a complex grid/graph? I'm imagining something where my page may open with a half dozen different grids (tabular data) stay updated via ajax interactions with various servers. UI elements provide control scale up or down a given grid with a quasi accordion slide kinda thingie. For example, one click on a scale up-or-down control would rescale the other viewports in the opposite direction. More clicks - more pronounced effect. So my 'how do i' question morphs into a 'how have others...' thx

• dynamic insert php mysql and preformance

  - by Ross

  I have a folder/array of images, it may be 1, maximum of 12. What I need to do is dynamically add them so the images are added to an images table. At the moment I have $directory = "portfolio_images/$id/Thumbs/"; $images = glob("" . $directory . "*.jpg"); for ( $i= 0; $i <= count($images); $i += 1) { mysql_query("INSERT INTO project_images (image_name, project_id)VALUES ('$images[0]', '$id')") or die(mysql_error()); } this is fine but it does not feel right, how is this for performance? Is there a better way? The maximum number of images is only ever going to be 12. Thanks, Ross

• How safe am I singing into Google Spreadsheets with yeroon.net/ggplot2

  - by Farrel

  I am impressed by what I have seen of yeroon.net/ggplot2 which is a web interface for Hadley Wickham's R package ggplot2. I want to try it out on my own data. The part that has me very excited is that one can use data stored in one's own Google spreadsheet as the data. One just signs into their Google Account so that yeroon.net/ggplot2 can access the spreadsheet list. I have been hesitant to do it. If I sign in whilst on yeroon.net am I handing over my username and password to a third party? It would not be wise of me to divulge my google password to third parties since Google is fast becoming my repository of everything. How do I know if Jeroon's application is using ClientLogin or OAuth? My understanding is very basic and may be wrong but nevertheless here it is. OAuth would be better since it does not actually pass the password onto the third party application.

• Spring GAE/J Could Not find API version error

  Hello, I am trying to use Spring MVC 3 on GAE/J and I got this error and I do not know what it means, does anybody have an idea and perhaps give me pointers on how to fix this?

• Getting sectionNameKeyPath to work with CoreData/UITableViewController

  - by Elon

  In my AppDelegate I create an NSFetchedResultsController with sectionNameKeyPath set to @"group". In viewWillAppear in my TableViewController I performFetch, then call a method called findGroups. findGroups does some complicated analysis of the entire dataset to identify groups, then sets the "group" transient property on each object to the correct string value. I can see with NSLog that these are all set correctly and in coherent groups. But, tinker as I may, my cells are shown in a single section with the title of the first group. Any ideas?

• ASP.NET MVC 2 validation using DTOs instead of domain entities

  - by Kevin Pang

  I'm struggling to mesh two best practices together: Using DataAnnotations + ModelBinding for validation in ASP.NET MVC 2 Using DTOs instead of domain entities when passing data via the ViewModel If I want to pass over DTOs instead of domain entities, then leveraging DataAnnotations + ModelBinding for validation would require me to specify validation attributes on my DTO classes. This results in a lot of duplicated work since multiple DTOs may hold overlapping fields with the same validation restrictions. This means that any time I change a validation rule in my domain, I have to go find all DTOs that correspond with that value and update their validation attributes.

• Changing UIImageView animation speed

  - by Nikolas Stephan

  I am using the UIImageView to animate a bunch of images. I know that I can change the speed by altering animationDuration, but that doesn't seem to take effect until the animation is restarted. My problem is that beside not really wanting to have to restart the animation as this limits me to only being able to change the speed once per cycle, there also doesn't seem to be a way to find out what frame is currently being shown and I would therefore have to rely on a timer to "guess" which one it is. So my question is whether there is a way to change the speed without restarting the animation and if not is there some way I could avoid the aforementioned problem? I'm not too keen to write my own animation class, but may end up having to if there isn't a nicer solution.

• CACLS Confusion

  - by codeulike

  During my NSIS setup script for a WinForms app, I use the following CACLS command to give the Users group full rights to a subfolder: Exec 'CACLS "$INSTDIR\SubFolder" /E /T /C /G "Users":F' So in effect the CACLS command executed is something like: CACLS "c:\Program Files\MyApp\SubFolder" /E /T /C /G "Users":F When I then look at the Folder permissions in Windows Explorer (right click on the folder and choose Properties, go to the Security tab), the correct permissions are there but they are uneditable. Furthermore, clicking the Advanced button for the 'Advanced Security Settings' shows that SubFolder is inheriting the "Users" group permissions from a 'Parent Object', but what is that Parent Object, because its not the folder above. Why are the permissions added by CACLS uneditable, and why are they inherited from nonexistent parent object? I thinking I may have set the options on CACLS wrong. I'm on Windows XP.

• FileInfo..ctor(string fileName) throwing exception: bug in SL 4.0 or .NET 4.0?

  - by Duncan Bayne

  The following test case passes in .NET 4.0: var fiT = new FileInfo("myhappyfilename"); Assert.IsNotNull(fiT); ... but fails in Silverlight 4.0 with the following error: System.ArgumentNullException: Value cannot be null. Parameter name: format at System.String.Format(IFormatProvider provider, String format, Object[] args) at System.Environment.GetResourceString(String key, Object[] values) at System.IO.FileSecurityState.EnsureState() at System.IO.FileInfo.Init(String fileName, Boolean checkHost) at System.IO.FileInfo..ctor(String fileName) Either the failure is a bug in SL 4.0, or the non-failure is a bug in .NET 4.0. Anyone know which it is? (For the record, I'm running SL 4.0 on VS 2010 RC, which may be contributing to the problem).

• How are these numbers converted to a readable Date/Time string?

  - by duckwizzle

  I have 2 XML files I'm reading - one has a date/time attribute that's readable (ex. May 1, 2010 12:03:14 AM) and the other... not so much (ex. 1272686594492). Both files have the complicated date/time format, but only the newer one has the readable version. I cannot figure out how to make the complicated version readable. Any ideas? The numbers are in the pastbin below. http://pastebin.com/HMLEAGhf Thanks!

• php vs python. scalability

  - by Quamis

  Why is PHP considered more scalable than python? I've heard may times that one of the reasons PHP is "better" than python is that PHP is more easily scalable, and that Yahoo proves that(assumig Yahoo still uses PHP). Whats the difference between PHP and Python when it comes to scalability? -- edit -- well, i have no evidence, the question arose after a discussion with a friend. -- edit2 -- here: http://www.oreillynet.com/ruby/blog/2007/09/7%5Freasons%5Fi%5Fswitched%5Fback%5Fto%5Fp%5F1.html , even if this dosent say anything about scaling..

• actionscript swf: why the swf is cached in one web server

  - by Bin Chen

  Hi, I have one swf and a program to load this swf. The swf is put in a server. I encounter a weird problem that if I put this swf in serverA, each time my program will issue a http request to that webserver(with 304 response). But when I move the swf from serverA to serverB, some weird things happen, the progrom will only issue the first time http request, and after that, it didn't send any http request, it looks like it uses the cache in the disk. I wonder is how can I configure serverA make the behavior the same as serverB, as I guess the problem may exists in the http response that make the program not retrieving the swf from serverB any more.

• Scrape HTML tables from a given URL into CSV

  - by dreeves

  I seek a tool that can be run on the command line like so: tablescrape 'http://someURL.foo.com' [n] If n is not specified and there's more than one HTML table on the page, it should summarize them (header row, total number of rows) in a numbered list. If n is specified or if there's only one table, it should parse the table and spit it to stdout as CSV or TSV. Potential additional features: To be really fancy you could parse a table within a table, but for my purposes -- fetching data from wikipedia pages and the like -- that's overkill. The Perl module HTML::TableExtract can do this and may be good place to start for writing the tool I have in mind. An option to asciify any unicode. An option to apply an arbitrary regex substitution for fixing weirdnesses in the parsed table. Related questions: http://stackoverflow.com/questions/259091/how-can-i-scrape-an-html-table-to-csv http://stackoverflow.com/questions/1403087/how-can-i-convert-an-html-table-to-csv http://stackoverflow.com/questions/2861/options-for-html-scraping

• Open Source/Free Social Networking SDK

  - by Nix

  I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extensible framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will more than likely consist of the following: IIS 7.0 WCF Data Services SQL Server 2005/2008 ASP.NET front end. So my two questions are 1) C# Open Source Social Network SDK 2) C# Open Source Social Netowrk APIs (facebook, linked in, etc) If there is any more information you may need please let me know.

• Reading multiple Emacs info files simultaneously

  - by pajato0

  For reading programming (and other) documentation, the Emacs INFO mode is outstanding. So outstanding that I would like to be able to read say, the Emacs Lisp info file and the org-mode info files simultaneously without traversing back up to the beginning of the info tree. Either I've missed something obvious or I will need to hack some Emacs Lisp to achieve the goal. And yet again, someone may have already cracked this nut. So I guess my question is: what is the state of the practice for reading mulitple INFO files in Emacs simultaneously?

• Grails Shiro plugin : confirming my understanding

  - by bsreekanth

  I'm bit vague about how to start using the shiro plugin, after reading few documents. I decided against Nimble, as it comes with few tables and UI plugins. I setup shiro plugin with wildcard realm, with my own tables. I may use permission based (rather tan role based) access control as it scales well. Now, the steps for it. assign the permission string to the subject, and save it in the db check the permission through isPermitted, hasPermission (or relevant tags in GSP). Now, 1. when to use the accesscontrol through filter? 2. is there a closure injected into the controller where I can define the permission for the actions in it? 3. How do I create a typical access control scenario like only the creator of (something, a post etc) can delete it? thanks a lot.. Babu.

• C# Pragma to suppress break on thrown error

  - by Courtney de Lautour

  First off I run my applications with exceptions thrown on any error (handled or not). Second I am using a TypeConverter to convert from a user input string to the actual object. Third TypeConverter offers no TryConvert method so I'm stuck using exceptions for validation, using this rather ugly bit of code here: try { this._newValue = null; #pragma Magic_SuppressBreakErrorThrown System.Exception this._newValue = this.Converter.ConvertFromString(this._textBox.Text); #pragma Magic_ResumeBreakErrorThrown System.Exception this.HideInvalidNotification(); } catch (Exception exception) { if (exception.InnerException is FormatException) { this.ShowInvalidNotification(this._textBox.Text); } else { throw; } } I'm finding it rather distracting to have VS break execution every-time I type the - of -1, or some other invalid character. I could use something similar to this but not all the types I'm converting to have a TryParse method either. I'm hoping there may be some way to disable breaking for the section of code within the try without changing my exception settings.

• Logic / Probability Question: Picking from a bag

  - by Rosarch

  I'm coding a board game where there is a bag of possible pieces. Each turn, players remove randomly selected pieces from the bag according to certain rules. For my implementation, it may be easier to divide up the bag initially into pools for one or more players. These pools would be randomly selected, but now different players would be picking from different bags. Is this any different? If one player's bag ran out, more would be randomly shuffled into it from the general stockpile.

• Enumerations and String values in ASP.NET

  - by Jason

  I'm looking for some best practice advice on enumerations and retrieving an associated string value. Given this: public enum SerialKillers { TedBundy, EdGein, AlbertFish, GeorgeBush } What is the best way to get a related string value of the name? Eg. "Ted Bundy", given that the string value may not match the representation in the enumeration. eg "George W Bush" My current thinking is function accepting an enum and returning a string, but would that not mean hard coding the string values (which I prefer not to do)? Is using a resources file where the string can be retrieved via the enumeration too heavy handed? Should I accept the fact I am going to Hell for victimising Ted Bundy by associating him with George Bush?
