• How do I read a secure rss feed into a SyndicationFeed without providing credentials?

  - by John Kaster

  For whatever reason, IBM uses https (without requiring credentials) for their RSS feeds. I'm trying to consume https://www.ibm.com/developerworks/mydeveloperworks/blogs/roller-ui/rendering/feed/gradybooch/entries/rss?lang=en with a .NET 4 SyndicationFeed. I can open this feed in a browser and it loads just fine. Here's the code: using (XmlReader xml = XmlReader.Create("https://www.ibm.com/developerworks/mydeveloperworks/blogs/roller-ui/rendering/feed/gradybooch/entries/rss?lang=en")) { var items = from item in SyndicationFeed.Load(xml).Items select item; } Here's the exception: System.Net.WebException was unhandled by user code Message=The remote server returned an error: (500) Internal Server Error. Source=System StackTrace: at System.Net.HttpWebRequest.GetResponse() at System.Xml.XmlDownloadManager.GetNonFileStream(Uri uri, ICredentials credentials, IWebProxy proxy, RequestCachePolicy cachePolicy) at System.Xml.XmlDownloadManager.GetStream(Uri uri, ICredentials credentials, IWebProxy proxy, RequestCachePolicy cachePolicy) at System.Xml.XmlUrlResolver.GetEntity(Uri absoluteUri, String role, Type ofObjectToReturn) at System.Xml.XmlReaderSettings.CreateReader(String inputUri, XmlParserContext inputContext) at System.Xml.XmlReader.Create(String inputUri, XmlReaderSettings settings, XmlParserContext inputContext) at System.Xml.XmlReader.Create(String inputUri) at EDN.Util.Test.FeedAggTest.LoadFeedInfoTest() in D:\cdn\trunk\CDN\Dev\Shared\net\EDN.Util\EDN.Util.Test\FeedAggTest.cs:line 126 How do I configure the reader to work with an https feed?

• How is jQuery so fast?

  - by ClarkeyBoy

  Hey, I have a rather large application which, on the admin frontend, takes a few seconds to load a page because of all the pageviews that it has to load into objects before displaying anything. Its a bit complex to explain how the system works, but a few of my other questions explains the system in great detail. The main difference between what they say and the current system is that the customer frontend no longer loads all the pageviews into objects when a customer first views the page - it simply adds the pageview to the database and creates an object in an unsynchronised list... to put it simply, when a customer views a page it no longer loads all the pageviews into objects; but the admin frontend still does. I have been working on some admin tools on the customer frontend recently, so if an administrator clicks the description of an item in the catalogue then the right hand column will display statistics and available actions for the selected item. To do this the page which gets loaded (through $('action-container').load(bla bla bla);) into the right hand column has to loop through ALL the pageviews - this ultimately means that ALL the pageviews are loaded into objects if they haven't been already. For some reason this loads really REALLY fast. The difference in speed is only like a second on my dev site, but the live site has thousands of pageviews so the difference is quite big... So my question is: why is it that the admin frontend loads so slowly while using $(bla).load(bla); is so fast? I mean whatever method jQuery uses, can't browsers use this method too and load pages super-fast? Obviously not as someone would've done that by now - but I am interested to know just why the difference is so big... is it just my system or is there a major difference in speed between the browser getting a page and jQuery getting a page? Do other people experience the same kind of differences? Thanks in advance, Regards, Richard

• Reduce number of config files to as few as possible

  - by Scott

  For most of my applications I use iBatis.Net for database access/modeling and log4Net for logging. In doing this, I need a number of *.config files for each project. For example, for a simple application I need to have the following *.config files: app.config ([AssemblyName].[Extention].config) [AssemblyName].SqlMap.config [AssemblyName].log4Net.config [AssemblyName].SqlMapProperties.config providers.config When these applications go from DEV to TEST to PRODUCTION environments, the settings contained in these files change depending on the environment. When the number of files get compounded by having 5-10 (or more) supporting executables per project, the work load on the infrastructure team (the ones doing the roll-outs to the different environments) gets rather high. We also have a high risk of one of the config files being missed, or a mistype in the config file. What is the best way to avoid these risks? Should I combine all of the config files into one file? (is that possible with iBatis?) I know that with VisualStudio 2010 they introduce transforms for these config files that allow the developer to setup all the settings for the different environments and then dynamically (depending on the build kicked off) the config files get updated to the correct versions. (VS 2010 - transforms) Thank you for any help that you can provide.

• Are there more Cocoa and Cocoa Touch videos which are worth looking at?

  - by dontWatchMyProfile

  To gain a better understanding, I think it would be a good idea to watch every cocoa video available on the net. I tend to find session videos from conferences or good podcast videos only by accident, so maybe someone has a handy list of links to great ressources. I already know all the WWDC stuff and the stuff from stanford, but a lot of universities around the world publish session videos as well in local languages. Also, there are like thousands of conferences around the world with great session videos. This list should compensate for all those who can't afford beeing at WWDC. Therefore, guys, let's create a handy list to fill the gaps for everyone! This is community wiki, so just list them all! I'll start with: English 360 Conferences (360iDev) Videos Oredev with some good iPhone dev session videos German Macoun 2009 with some interesting session videos, if you can speak German Please don't hesitate to post links to videos in other languages than English. Many of us speak more languages, so go ahead! We'll be excited!

• How can I capture Rake output when invoked from with a Ruby script?

  - by Adrian O'Connor

  I am writing a web-based dev-console for Rails development. In one of my controller actions, I am calling Rake, but I am unable to capture any of the output that Rake generates. For example, here is some sample code, from the controller: require 'rake' require 'rake/rdoctask' require 'rake/testtask' require 'tasks/rails' require 'stringio' ... def show_routes @results = capture_stdout { Rake.tasks['routes'].invoke } # @results is nil -- the capture_stdout doesn't catpure anything that Rake generates end def capture_stdout s = StringIO.new $stdout = s yield s.string ensure $stdout = STDOUT end Does anybody know why I can't capture the Rake output? I've tried going through the Rake source, and I can't see where it fires a new process or anything, so I think I ought to be able to do this. Many thanks! Adrian I have since discovered the correct way to call Rake from inside Ruby that works much better: Rake.application['db:migrate:redo'].reenable Rake.application['db:migrate:redo'].invoke Strangely, some rake tasks work perfectly now (routes), some capture the output the first time the run and after that are always blank (db:migrate:redo) and some don't seem to ever capture output (test). Odd.

• Exclude string from wildcard in bash

  - by Peter O'Doherty

  Hi, I'm trying to adapt a bash script from "Sams' Teach Yourself Linux in 24 Hours" which is a safe delete command called rmv. The files are removed by calling rmv -d file1 file2 etc. In the original script a max of 4 files can by removed using the variables $1 $2 $3 $4. I want to extend this to an unlimited number of files by using a wildcard. So I do: for i in $* do mv $i $HOME/.trash done The files are deleted okay but the option -d of the command rmv -d is also treated as an argument and bash objects that it cannot be found. Is there a better way to do this? Thanks, Peter #!/bin/bash # rmv - a safe delete program # uses a trash directory under your home directory mkdir $HOME/.trash 2>/dev/null # four internal script variables are defined cmdlnopts=false delete=false empty=false list=false # uses getopts command to look at command line for any options while getopts "dehl" cmdlnopts; do case "$cmdlnopts" in d ) /bin/echo "deleting: \c" $2 $3 $4 $5 ; delete=true ;; e ) /bin/echo "emptying the trash..." ; empty=true ;; h ) /bin/echo "safe file delete v1.0" /bin/echo "rmv -d[elete] -e[mpty] -h[elp] -l[ist] file1-4" ;; l ) /bin/echo "your .trash directory contains:" ; list=true ;; esac done if [ $delete = true ] then for i in $* do mv $i $HOME/.trash done /bin/echo "rmv finished." fi if [ $empty = true ] then /bin/echo "empty the trash? \c" read answer case "$answer" in y) rm -i $HOME/.trash/* ;; n) /bin/echo "trashcan delete aborted." ;; esac fi if [ $list = true ] then ls -l $HOME/.trash fi

• Migrating to web application with AjaxControlToolkit

  - by Chris

  Hi All, We are currently migrating our ASP.NET website to a web application in Visual Studio 2008. Most of the process has been fairly straight forward, but I have hit one block that is driving me a bit nuts. We are using the AjaxControlToolkit for some functionality, specifically an AutoControlExtender. When this is run locally through VS's development server the extender (dropdown) does not render after the service returns the resultset. However if I deploy the migrated solution to our UAT server the extender functions correctly. I have ensured the Ajax Control Toolkit is properly installed locally on my dev machine (and the dll available in the bin directory), and using debugging have ensured the service is called correctly and runs through without error (which it does). The web application was taken from a server running IIS7. Can anyone confirm if Visual Studio 2008 development server requires a different configuration to IIS 7 (as I believe IIS 6 requires a different configuration to IIS 7), and if there is a resource that provides more info? My own searches have turned up very little in this area. On the other hand, if I am looking in the wrong area any other tips would be appreciated. Thanks Chris

• How do I use an SWT Control to render the content of an SWT/JFace table?

  - by jastram

  I have a JFace TableViewer with an SWT Table, and I would like to custom render the content of some cells. I would like to use an SWT Control to render the cell content. I would prefer to have only one instance of the Control doing the rendering, but if I have to instantiate one for each row, that would be acceptable. Next, the solution MUST be compatible with the ContentProvider/LabelProvider approach (I am using EMF). This means that I cannot use the solution described in Sniplet 126 (http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets). Next, I though about using custom drawing. But here the catch is, that I have to send individual drawing operations to the graphics context. I was trying to have the Control render the content for me by calling redraw() or print(GC) upon SWT.PaintItem, but that just lead to uncontrollable flickering. At this point, my best guess is to use SWT.PaintItem to do the drawing. This will result in duplicate code, as I already have a Control that can render the content the way I'd like it. I'd like to prevent this redundancy. Any help is appreciated!

• "QFontEngine(Win) GetTextMetrics failed ()" error on 64-bit Windows

  - by David Murdoch

  I'll add 500 of my own rep as a bounty when SO lets me. I'm using wkhtmltopdf to convert HTML web pages to PDFs. This works perfectly on my 32-bit dev server [unfortunately, I can't ship my machine :-p ].

• SQLiteDataAdapter Fill exception C# ADO.NET

  - by Lirik

  I'm trying to use the OleDb CSV parser to load some data from a CSV file and insert it into a SQLite database, but I get an exception with the OleDbAdapter.Fill method and it's frustrating: An unhandled exception of type 'System.Data.ConstraintException' occurred in System.Data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is the source code: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=No;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); // <-- Exception here InsertData(ds, tableName); // <-- Inserts the data into the my SQLite db } } } class Program { static void Main(string[] args) { SQLiteDatabase target = new SQLiteDatabase(); string csvFileName = "D:\\Innovations\\Finch\\dev\\DataFeed\\YahooTagsInfo.csv"; string tableName = "Tags"; target.InsertData(csvFileName, tableName); Console.ReadKey(); } } The "YahooTagsInfo.csv" file looks like this: tagId,tagName,description,colName,dataType,realTime 1,s,Symbol,symbol,VARCHAR,FALSE 2,c8,After Hours Change,afterhours,DOUBLE,TRUE 3,g3,Annualized Gain,annualizedGain,DOUBLE,FALSE 4,a,Ask,ask,DOUBLE,FALSE 5,a5,Ask Size,askSize,DOUBLE,FALSE 6,a2,Average Daily Volume,avgDailyVolume,DOUBLE,FALSE 7,b,Bid,bid,DOUBLE,FALSE 8,b6,Bid Size,bidSize,DOUBLE,FALSE 9,b4,Book Value,bookValue,DOUBLE,FALSE I've tried the following: Removing the first line in the CSV file so it doesn't confuse it for real data. Changing the TRUE/FALSE realTime flag to 1/0. I've tried 1 and 2 together (i.e. removed the first line and changed the flag). None of these things helped... One constraint is that the tagId is supposed to be unique. Here is what the table look like in design view: Can anybody help me figure out what is the problem here?

• Binary file email attachment problem

  - by Alan Harris-Reid

  Hi there, Using Python 3.1.2 I am having a problem sending binary attachment files (jpeg, pdf, etc.) - MIMEText attachments work fine. The code in question is as follows... for file in self.attachments: part = MIMEBase('application', "octet-stream") part.set_payload(open(file,"rb").read()) encoders.encode_base64(part) part.add_header('Content-Disposition', 'attachment; filename="%s"' % file) msg.attach(part) # msg is an instance of MIMEMultipart() server = smtplib.SMTP(host, port) server.login(username, password) server.sendmail(from_addr, all_recipients, msg.as_string()) However, way down in the calling-stack (see traceback below), it looks as though msg.as_string() has received an attachment which creates a payload of 'bytes' type instead of string. Has anyone any idea what might be causing the problem? Any help would be appreciated. Alan builtins.TypeError: string payload expected: File "c:\Dev\CommonPY\Scripts\email_send.py", line 147, in send server.sendmail(self.from_addr, all_recipients, msg.as_string()) File "c:\Program Files\Python31\Lib\email\message.py", line 136, in as_string g.flatten(self, unixfrom=unixfrom) File "c:\Program Files\Python31\Lib\email\generator.py", line 76, in flatten self._write(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 101, in _write self._dispatch(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 127, in _dispatch meth(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 181, in _handle_multipart g.flatten(part, unixfrom=False) File "c:\Program Files\Python31\Lib\email\generator.py", line 76, in flatten self._write(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 101, in _write self._dispatch(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 127, in _dispatch meth(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 155, in _handle_text raise TypeError('string payload expected: %s' % type(payload))

• What strategy do you use to sync your code when working from home

  - by Ben Daniel

  At my work I currently have my development environment inside a Virtual Machine. When I need to do work from home I copy my VM and any databases I need onto a laptop drive sized external USB drive. After about 10 minutes of copying I put the drive in my pocket and head home, copy back the VM and databases onto my personal computer and I'm ready to work. I follow the same steps to take the work back with me. So if I count the total amount of time I spend waiting around for files to finish copying in order for me to take work home and bring it back again, it comes to around 40 minutes! I do have a VPN connection to my work from home (providing the internet is up at both sites) and a decent internet speed (8mbits down/?up) but I find Remote Desktoping into my work machine laggy enough for me to want to work on my VM directly. So in looking at what other options I have or how I could improve my existing option I'm interested in what strategy you use or recommend to do work at home and keeping your code/environment in sync. EDIT: I'd prefer an option where I don't have to commit my changes into version control before I leave work - as I like to make meaningful descriptive comments in my commits, committing would take longer than just copying my VM onto a portable drive! lol Also I'd prefer a solution where my dev environment stays in sync too. Having said that I'm still very interested in your own solutions even if they don't exactly solve my problem as best as I'd like. :)

• Trying to use a authlogic-connect as a plugin in place of gem - Server doesn't start

  - by Arkid

  I am trying to use Authlogic-connect as a plugin in Rails 3 in place of a gem. I have made an entry in the gemfile as gem "authlogic-connect", :require => "authlogic-connect", :path => "localgems" Now when I run the bundle install, it runs fine. When I try to start the server i get the error Could not find gem 'authlogic-connect (>= 0, runtime)' in source at localgems.

• Dropdown menu disappears in IE7

  - by Justine

  A weird problem with a dropdown menu in IE7: http://screenr.com/SNM The dropdown disappears when the mouse moves to a part that hovers above other layers. The HTML structure looks like this: <div class="header"> <ul class="nav> <li><a href="">item</a> <ul><li><a href="">sub-item</a></li></ul> </li> </ul> </div><!-- /header--> <div class="featured"></div> <div class="content"></div> The sub-menu is positioned absolutely and has visibility:hidden, then it's set to visible using jQuery, like so: $(".header ul.nav li").hover(function(){ $(this).addClass("hover"); $('ul:first',this).css('visibility', 'visible'); }, function(){ $(this).removeClass("hover"); $('ul:first',this).css('visibility', 'hidden'); }); I had a problem with the dropdown hiding under other content in IE7, fixed easily by giving the z-index to its parent and other divs: *:first-child+html .header { position: relative; z-index: 2 !important; } *:first-child+html .content, *:first-child+html .main, *:first-child+html .primary *:first-child+html .featured { position: relative; z-index: 1 !important; } Now, I have no idea why the menu disappears when hovered over other divs, you can view the site live here: http://dev.gentlecode.net/ama/ubezpieczenia.html I would love any help, been staring at this code for ages now without any solution. I guess it's just me tunnel visioning already... Thanks in advance for any help!

• Proper way to set PYTHONPATH (including precedence)

  - by Wells

  In .bashrc I have: export PYTHONPATH=/home/wells/py-mlb I've verified this is actually being set. so, in this directory is another directory called 'py_mlb'- the actual module. So I go python -v and then import py_mlb but it does: >>> import py_mlb import py_mlb # directory /usr/local/lib/python2.6/dist-packages/py_mlb Then I do import sys and print sys.path and I see: >>> print sys.path ['', '/usr/local/lib/python2.6/dist-packages/python_memcached-1.44-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/pymc-2.1alpha-py2.6-linux-i686.egg', '/usr/local/lib/python2.6/dist-packages/nose-0.11.1-py2.6.egg', '/home/wells/py-mlb', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/local/lib/python2.6/dev-packages', '/usr/lib/pymodules/python2.6', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/local/lib/python2.6/dist-packages'] So my path from .bashrc IS in there, and from the look of it it's even before dist-packages but it's importing the module from dist-packages. How can I finagle this so the PYTHONPATH as defined by .bashrc takes precedence? Thanks!

• jQuery problem with change event and IE8

  - by Marcus

  There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8. Here is the test code: <html> <head> <script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery(".myDropDown").change(function() { }); }); </script> </head> <body> <select class="myDropDown" onchange="alert('hello');"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> </select> </body> </html> Ticket to actual bug: http://dev.jquery.com/ticket/6593 This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem. Is there anyone who knows a way around this in the meantime until this issue is fixed?

• How do you tune Eclipse IDE? How do you use Eclipse IDE?

  - by Kirzilla

  Hello, I've started to read the book "Code Craft" by Pete Goodliffe. The fourth chapter is about instruments that developer uses during his daily work; this chapter made me to review my work and I've seriously decided to make it easier with fully personalized IDE. Eclipse IDE is what I've started my learning from... I've read documentation and found that it's really easy to do tasks routine from Eclipse. We are using Mantis for tracking tasks and it was great surprise for me to find out Mantis Connector for Mylyn. Also I was pretty glad to see SVN client integrated into Eclipse IDE. Also I've found UML2 tool for Eclipse, but was disappointed because there is no any graphic interface for building diagramms. (Or, maybe, I'm was searching in wrong place?) What useful plugins do you use in your daily work? How do you use Eclipse for collaboration in your team? Do you have any links about intergration Eclipse IDE experience in dev. team? Thank you!

• Sharepoint: Integrity of lookup fields after a list import

  - by driAn

  Hi there I got a question about the behavior of lookup fields when importing data. I wonder how the lookup fields behave when the list they point to is being replaced/imported. To explain the issue, I will provide a quick example below: As example, assume we have these two sharepoint lists: Product Types ------------- + Type Name + Code Nr + etc Products -------- + Product Name + Product Type (Lookup field to list "Product Types") + etc In my scenario, the Products List contains production data on the production Sharepoint platform. It is filled with data by the business users. However the Product Types list contains rather static data and is maintained by the developer. Now after a development cycle, the developer wants to deploy his new webparts and his new data (product types list). The developer performs the following procedure: On the dev machine: Export "product type" list using stsadm On the production machine: Delete all items in the "product type" list On the production machine: Import the "product type" list using stsadm This means we basically replace the "product type" list on the production server while keeping the "product" list as it is. Now the question: Is this safe? Will the lookup references break under certain circumstances? Any downside of this import/export procedure? What happens if someone accesses a "product" during the import? Will the (now invalid) reference clear its own content (become a null value). What happens if the schema of the "product type" list changes (new column)? Will this cause any troubles? Thanks for all feedback and suggestions!

• Learning Objective-C: Need advice on populating NSMutableDictionary

  - by Zigrivers

  I am teaching myself Objective-C utilizing a number of resources, one of which is the Stanford iPhone Dev class available via iTunes U (past 2010 class). One of the home work assignments asked that I populate a mutable dictionary with a predefined list of keys and values (URLs). I was able to put the code together, but as I look at it, I keep thinking there is probably a much better way for me to approach what I'm trying to do: Populate a NSMutableDictionary with the predefined keys and values Enumerate through the keys of the dictionary and check each key to see if it starts with "Stanford" If it meets the criteria, log both the key and the value I would really appreciate any feedback on how I might improve on what I've put together. I'm the very definition of a beginner, but I'm really enjoying the challenge of learning Objective-C. void bookmarkDictionary () { NSMutableDictionary* bookmarks = [NSMutableDictionary dictionary]; NSString* one = @"Stanford University", *two = @"Apple", *three = @"CS193P", *four = @"Stanford on iTunes U", *five = @"Stanford Mall"; NSString* urlOne = @"http://www.stanford.edu", *urlTwo = @"http://www.apple.com", *urlThree = @"http://cs193p.stanford.edu", *urlFour = @"http://itunes.stanford.edu", *urlFive = @"http://stanfordshop.com"; NSURL* oneURL = [NSURL URLWithString:urlOne]; NSURL* twoURL = [NSURL URLWithString:urlTwo]; NSURL* threeURL = [NSURL URLWithString:urlThree]; NSURL* fourURL = [NSURL URLWithString:urlFour]; NSURL* fiveURL = [NSURL URLWithString:urlFive]; [bookmarks setObject:oneURL forKey:one]; [bookmarks setObject:twoURL forKey:two]; [bookmarks setObject:threeURL forKey:three]; [bookmarks setObject:fourURL forKey:four]; [bookmarks setObject:fiveURL forKey:five]; NSString* akey; NSString* testString = @"Stanford"; for (akey in bookmarks) { if ([akey hasPrefix:testString]) { NSLog(@"Key: %@ URL: %@", akey, [bookmarks objectForKey:akey]); } } } Thanks for your help!

• Crystal Reports Failed Database Login

  - by Marlon

  Hello, After spending a good 3 to 4 hours on google trying to find any solution to my problem I haven't had much luck. Basically, we use crystal reports for our .NET applications with a sql server back end, we have many clients each with their own server and so our reports need to have their connections dynamically set. Up until a week ago this worked fine. However a few days ago a client reported they were getting a database login prompt for a report (only one report, the rest worked fine). We were quite stumped but we managed to reproduce it on a netbook which didn't have visual studio or sql server installed. In the end the dev decided to reproduce the report in the hope it was just an oddity in that particular report. Unfortunately a new client today also experienced the same problem, but this time for every crystal report they had - and also they worked on the netbook, so we are really quite lost here. Below is a screenshot of what our clients get presented with - and here is the code that I use to set the connection information in the report cI.ServerName = (string)builder["Data Source"]; cI.DatabaseName = (string)builder["Initial Catalog"]; cI.UserID = (string)builder["User ID"]; cI.Password = (string)builder["Password"]; foreach (IConnectionInfo info in cryRpt.DataSourceConnections) { info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password); } foreach (ReportDocument sub in cryRpt.Subreports) { foreach (IConnectionInfo info in sub.DataSourceConnections) { info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password); } } As always, any help much appreciated.

• Shopify JSONP issue in ajaxAPI

  - by Aaron U

  I'm getting some odd response back from shopify ajaxapi for jsonp. If you cURL a Shopify ajax api location http://storename.domain.com/cart.json?callback=handler you will get a jsonp response. But something is breaking the same request in browsers. It appears to be related to compression? Here are some responses from each browser when attempting to call the jsonp as documented. Firefox: The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Internet Explorer: Internet Explorer cannot display the webpage Chrome/Safari/Webkit: Cannot decode raw data, or failed (chrome) Attempted use via jquery: $.getJSON('http://storename.domain.com/cart.json?callback=?', function(data) { ... }); // Results in a failed request, viewable network request panels of dev tools Here is some output from cURL including response headers: $ curl -i http://storename.domain.com/cart.json?callback=CALLBACK_FUNC HTTP/1.1 200 OK Server: nginx Date: Tue, 18 Dec 2012 13:48:29 GMT Content-Type: application/javascript; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive Status: 200 OK ETag: cachable:864076445587123764313132415008994143575 Cache-Control: max-age=0, private, must-revalidate X-Alternate-Cache-Key: cachable:11795444887523410552615529412743919200 X-Cache: hit, server X-Request-Id: a0c33a55230fe42bce79b462f6fe450d X-UA-Compatible: IE=Edge,chrome=1 Set-Cookie: _session_id=b6ace1d7b0dbedd37f7787d10e173131; path=/; HttpOnly X-Runtime: 0.033811 P3P: CP="NOI DSP COR NID ADMa OPTa OUR NOR" CALLBACK_FUNC({"token":null,"note":null,"attributes":{},"total_price":0,...}) Also related unanswered here: Shopify Ajax API JSONP supported?

• Has Twisted changed its dependencies?

  - by cdecker

  Hi all, I'm currently working on a Python/Twisted project which is to be distributed and tested on Planetlab. For some reason my code was working on friday and now that I wanted to test a minor change it refuses to work at all: Traceback (most recent call last): File "acn_a4/src/node.py", line 6, in <module> from twisted.internet.protocol import DatagramProtocol File "/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/__init__.py", line 18, in <module> from twisted.python import compat File "/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/python/compat.py", line 146, in <module> import operator File "/home/cdecker/dev/acn/acn_a4/src/operator.py", line 7, in <module> File "/home/cdecker/acn_a4/src/node.py", line 6, in <module> from twisted.internet.protocol import DatagramProtocol File "/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/internet/protocol.py", line 20, in <module> from twisted.python import log, failure, components File "/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/python/log.py", line 19, in <module> from twisted.python import util, context, reflect File "/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/python/util.py", line 5, in <module> import os, sys, hmac, errno, new, inspect, warnings File "/usr/lib/python2.5/inspect.py", line 32, in <module> from operator import attrgetter ImportError: cannot import name attrgetter And since I'm pretty new to python I have no idea what could have caused this problem.
