  • MVC moq unit test the object before RedirecToAction()

    - by Daoming Yang
    I want to test the data inside the "item" object before it redirect to another action. public ActionResult WebPageEdit(WebPage item, FormCollection form) { if (ModelState.IsValid) { item.Description = Utils.CrossSiteScriptingAttackCheck(item.Description); item.Content = Utils.CrossSiteScriptingAttackCheck(item.Content); item.Title = item.Title.Trim(); item.DateUpdated = DateTime.Now; // Other logic stuff here webPagesRepository.Save(item); return RedirectToAction("WebPageList"); } Here is my Test method: [Test] public void Admin_WebPageEdit_Save() { var controller = new AdminController(); controller.webPagesRepository = DataMock.WebPageDataInit(); controller.categoriesRepository = DataMock.WebPageCategoryDataInit(); FormCollection form = DataMock.CreateWebPageFormCollection(); RedirectToRouteResult actionResult = (RedirectToRouteResult)controller.WebPageEdit(webPagesRepository.Get(1), form); Assert.IsNotNull(actionResult); Assert.AreEqual("WebPageList", actionResult.RouteValues["action"]); var item = ((ViewResult)controller.WebPageEdit(webPagesRepository.Get(1), form)).ViewData.Model as WebPage; Assert.NotNull(item); Assert.AreEqual(2, item.CategoryID); } It failed at this line: var item = ((ViewResult)controller.WebPageEdit(webPagesRepository.Get(1), form)).ViewData.Model as WebPage; I am thinking about is there any ways to test the "item" object before it redirect to other actions?

  • Try/Catch with jquery ajax request

    - by Anthony
    I am trying to build a Google Chrome extension that makes an ajax request. Something similar to the GMail Checker extension. The problem is that when I do the request using jquery, and I put in the wrong username/password, it fails silently, with the error callback function ignored. If I move the ajax call out of the background.html script (where I can't see the requests in the developer window), to the options.html script, I get a dialog box to re-authenticate. If I hit cancel, THEN the jquery error callback fires. But in the original model extension (again, the Gmail checker), they use plain (non-jquery) ajax calls with a try/catch, and if I put in the wrong credentials, I get an alert saying as much. I tried wrapping the entire jquery call in a try/catch, like so: try { $.ajax({ type: "POST", url: someurl, contentType : "text/xml", data: somedata, username: user, password: pass, success: function(data,status,xhr){ alert("Hurrah!"); }, error: function(xhr, status, error){ alert("Error!" + xhr.status); }, dataType: "xml" }); } catch(e) { alert("You messed something up!"); } But still nothing. Is the error due to it being asynchronous, or is Chrome not returning the request as an error since it wants to re-prompt for credentials? Or do I just not know how to use try/catch? Update Here is a very slimmed down version of how the model code does the request: var req = new XMLHttpRequest(); req.onreadystatechange = function() { try { if ( req.readyState == 4 ) { //Do some stuff with results } } catch (ex) { alert('Error parsing response.'); } } try { req.send (data); } catch (ex) { alert ('Something went wrong with the request.'); }

  • How to use Guice in Swing application

    - by Gerco Dries
    I have a Swing application that I would like to convert from spaghetti to using dependency injection with Guice. Using Guice to provide services like configuration and task queues is going great but I'm now starting on the GUI of the app and am unsure of how to proceed. The application is basically a JFrame with a bunch of tabs in a JTabbedPane. Each of the tabs is a separate JPanel subclass that lays out the various components and needs services to perform actions when certain buttons are pressed. In the current application, this looks somewhat like this: @Inject public MainFrame(SomeService service, Executor ex, Configuration config) { tabsPane = new JTabbedPane(); // Create the panels for each tab and add them to the tabbedpane somePanel = new SomeTabPanel(service, ex, config); tabsPane.addTab("Panel 1", somePanel); someOtherPanel = new SomeOtherTabPanel(service, ex, config); tabsPane.addTab("Panel 2", someOtherPanel); ... do more stuff } Obviously, this doesn't exactly follow DI best practices. I don't want to have to @Inject the tabs because that would get me a constructor with dozens of parameters. I do want to use Guice to inject the required dependencies into whatever tab objects I need without me having to pass all of those dependencies to the tab constructors. All of the dependencies for the tab objects are services that my Module knows about, so basically all I think I want to do is to ask Guice for the required objects and have them constructed for me.

  • How to use Scala in IntelliJ IDEA (or: why is it so difficult to get a working IDE for Scala)?

    - by Alex R
    I recently gave up trying to use Scala in Eclipse (basic stuff like completion doesn't work). So now I'm trying IntelliJ. I'm not getting very far. I've been able to edit programs (within syntax highlighting and completion... yay!). But I'm unable to run even the simplest "Hello World". This was the original error: Scala signature Predef has wrong version Expected 5.0 found: 4.1 in .... scala-library.jar But that was yesterday with IDEA 9.0.1. See below... UPDATE Today I uninstalled IntelliJ 9.0.1, and installed 9.0.2 Early Availability, with the 4/14 stable version of the Scala plug-in. Then I setup a project from scratch through the wizards: new project from scratch JDK is 1.6.u20 accept the default (project) instead of global / module accept the download of Scala 2.8.0beta1 into project's lib folder Created a new class: object hello { def main(args: Array[String]) { println("hello: " + args); } } For my efforts, I now have a brand-new error :) Here it is: Scalac internal error: class java.lang.ClassNotFoundException [java.net.URLClassLoader$1.run(URLClassLoader.java:202), java.security.AccessController.doPrivileged(Native Method), java.net.URLClassLoader.findClass(URLClassLoader.java:190), java.lang.ClassLoader.loadClass(ClassLoader.java:307), sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301), java.lang.ClassLoader.loadClass(ClassLoader.java:248), java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:169), org.jetbrains.plugins.scala.compiler.rt.ScalacRunner.main(ScalacRunner.java:72)] FINAL UPDATE I uninstalled 9.0.2 EA and reinstalled 9.0.1, but this time went with the 2.7.3 version of Scala rather than the default 2.7.6, because 2.7.3 is the one shown in the screen-shots at the IntelliJ website (I guess the screen-shots prove that they actually tested this version!). Now everything works!!!

  • SharePoint 2010 HttpModule problem

    - by Chris W
    I'm trying to write an HttpModule to run on our SharePoint farm - essentially it will check whether the user is authenticated and if they are it will validate some info against another database and potentially redirect the user to sign a variety of usage agreements. Whenever I enable the module in the web.config I'm finding that SharePoint has issues rendering the page - it's almost like the CSS is not getting loaded as the page is devoid of any styling. As a test I've even tried an empty module - i.e. an empty init block so it's not even hooking up any code to any events and the same issue arises. At this point it's an empty class that just implements IHttpModule so it's not even my dodgy coding causing the issue! The module is in a class library that I've dropped in to the bin folder of the application it needs to run against. In the web.config of the app I've simply added an entry as below: <modules runAllManagedModulesForAllRequests="true"> ... (default stuff ommitted) <add name="SharePointAUP" type="SPModules.SharePointAUP" /> </modules> I must be missing something really obvious here as I've done exactly the same as every sample I've found and yet I'm getting this strange behaviour. Is there something extra I need to do to get SharePoint to play nice with a custom module?

  • UISearchDisplayController "shouldReloadTableForSearchString return NO" reloads table

    - by Jeena
    Why does my UISearchDisplayController show "No results" even if the shouldReloadTableForSearchString method returns NO? Shouldn't it just do nothing and stay black? How can I prevent it from doing so? #import "RootViewController.h" #pragma mark Table view methods - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } // Customize the number of rows in the table view. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (tableView == self.searchDisplayController.searchResultsTableView) { return 0; } return 10; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. cell.textLabel.text = [NSString stringWithFormat:@"row %d", indexPath.row]; return cell; } #pragma mark SearchController stuff - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { return NO; } - (void)dealloc { [super dealloc]; } @end

  • jQuery addClass on $.post

    - by Tim
    I am basically trying to create a small registration form. If the username is already taken, I want to add the 'red' class, if not then 'green'. The PHP here works fine, and returns either a "YES" or "NO" to determine whether it's ok. The CSS: input { border:1px solid #ccc; } .red { border:1px solid #c00; } .green { border:1px solid green; background:#afdfaf; } The Javascript I'm using is: $("#username").change(function() { var value = $("#username").val(); if(value!= '') { $.post("check.php", { value: value }, function(data){ $("#test").html(data); if(data=='YES') { $("#username").removeClass('red').addClass('green'); } if(data=='NO') { $("#username").removeClass('green').addClass('red'); } }); } }); I've got the document.ready stuff too... It all works fine because the #test div html changes to either "YES" or "NO", apart from the last part where I check what the value of the data is. Here is the php: $value=$_POST['value']; if ($value!="") { $sql="select * FROM users WHERE username='".$value."'"; $query = mysql_query($sql) or die ("Could not match data because ".mysql_error()); $num_rows = mysql_num_rows($query); if ($num_rows 0) { echo "NO"; } else { echo "YES"; } }

  • What are best practices for collecting, maintaining and ensuring accuracy of a huge data set?

    - by Kyle West
    I am posing this question looking for practical advice on how to design a system. Sites like amazon.com and pandora have and maintain huge data sets to run their core business. For example, amazon (and every other major e-commerce site) has millions of products for sale, images of those products, pricing, specifications, etc. etc. etc. Ignoring the data coming in from 3rd party sellers and the user generated content all that "stuff" had to come from somewhere and is maintained by someone. It's also incredibly detailed and accurate. How? How do they do it? Is there just an army of data-entry clerks or have they devised systems to handle the grunt work? My company is in a similar situation. We maintain a huge (10-of-millions of records) catalog of automotive parts and the cars they fit. We've been at it for a while now and have come up with a number of programs and processes to keep our catalog growing and accurate; however, it seems like to grow the catalog to x items we need to grow the team to y. I need to figure some ways to increase the efficiency of the data team and hopefully I can learn from the work of others. Any suggestions are appreciated, more though would be links to content I could spend some serious time reading. THANKS! Kyle

  • PHP session_write_close() causes empty response

    - by Xeoncross
    When using session_write_close() in a shutdown function at the end of my script - PHP just dies. There is no error logged, response headers (firebug), or data (even whitespace!) returned. I have full PHP error reporting on with STRICT enabled and PHP 5.2.1. My guess is that since session_write_close() is being called after shutdown - some fatal error is being encountered that crashes PHP before it has a chance to send the output or log anything. This only happens on the logout page where I first: ... //If there is no session to delete (not started) if ( ! session_id()) { return; } // Get the session name $name = session_name(); // Delete the session cookie (if exists) if ( ! empty($_COOKIE[$name])) { //Get the current cookie config $params = session_get_cookie_params(); // Delete the cookie from globals unset($_COOKIE[$name], $_SESSION); //Delete the cookie on the user_agent setcookie($name, '', time()-43200, $params['path'], $params['domain'], $params['secure']); } // Destroy the session session_destroy(); ... then 2) do some more stuff 3) issue a redirect and 4) finally, after the whole page is done the register_shutdown_function(); I placed earlier runs and calls session_write_close() which saves the session to the database. The end. Since this blank response only occurs on logout I'm guessing that I'm not restarting the session properly which is causing session_write_close() to die fatally at the end of the script.

  • File extensions and MIME Types in .NET

    - by Marc Climent
    I want to get a MIME Content-Type from a given extension (preferably without accessing the physical file). I have seen some questions about this and the methods described to perform this can be resumed in: Use registry information. Use urlmon.dll's FindMimeFromData. Use IIS information. Roll your own MIME mapping function. Based on this table, for example. I've been using no.1 for some time but I realized that the information provided by the registry is not consistent and depends on the software installed on the machine. Some extensions, like .zip don't use to have a Content-Type specified. Solution no.2 forces me to have the file on disk in order to read the first bytes, which is something slow but may get good results. The third method is based on Directory Services and all that stuff, which is something I don't like much because I have to add COM references and I'm not sure it's consistent between IIS6 and IIS7. Also, I don't know the performance of this method. Finally, I didn't want to use my own table but at the end seems the best option if I want a decent performance and consistency of the results between platforms (even Mono). Do you think there's a better option than using my own table or one of other described methods are better? What's your experience?

  • problem with addressfilter in WCF

    - by Zé Carlos
    I've build my own WCF channel with all necessary stuff (like encoders, bindings, etc) to use it with ServiceHost. I just want to build the "channel stack" making no custumizations at "Service Model". To acomplish this, my encoder returns perfect ServiceModel.Messages with a XML infoset just like other channel does. Lets assume the following service implementation: [ServiceContract(Namespace = "http://MyNS")] public interface IService1 { [OperationContract(IsOneWay = true)] void dummy(); } public class Service1 : IService1 { public void dummy() { Console.WriteLine("In Service1:dummy()"); } } I used this service through other bindings and traced the following ServiceModel.Message contents (SOAP format): <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing"> <s:Header> <a:Action s:mustUnderstand="1">http://MyNS/IService1/dummy</a:Action> <a:To s:mustUnderstand="1">amqp://localhost</a:To> </s:Header> <s:Body> <dummy xmlns="http://MyNS"></dummy> </s:Body> </s:Envelope> Then (just to debug) i changed my encoder to allways return this message. When i use my custom channel the WCF's runtime replay with an faul message telling: "The message with To '' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree." I read that the default EndPointDispatcher.AddressFilter simply looks to the "TO" header and delivery the message to corresponding service. This is happening with other bindings, why not happens with my custom channel too? Is there any way to i check what default AddressFilter is doing? Thanks

  • Problem with XElement and XslCompiledTransform

    - by Graham Clark
    I'm having some trouble using a combination of XElement and XslCompiledTransform. I've put the sample code I'm using below. If I get my input XML using the GetXmlDocumentXml() method, it works fine. If I use the GetXElementXml() method instead, I get an InvalidOperationException when calling the Transform method of XslComiledTransform: Token Text in state Start would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. The CreateNavigator method on both XElement and XmlDocument returns an XPathNavigator. What extra stuff is XmlDocument doing so this all works, and how can I do the same with XElement? Am I just doing something insane? static void Main(string[] args) { XslCompiledTransform stylesheet = GetStylesheet(); // not shown for brevity IXPathNavigable input = this.GetXElementXml(); using (MemoryStream ms = this.TransformXml(input, stylesheet)) { XmlReader xr = XmlReader.Create(ms); xr.MoveToContent(); } } private MemoryStream TransformXml( IXPathNavigable xml, XslCompiledTransform stylesheet) { MemoryStream transformed = new MemoryStream(); XmlWriter writer = XmlWriter.Create(transformed); stylesheet.Transform(xml, null, writer); transformed.Position = 0; return transformed; } private IXPathNavigable GetXElementXml() { var xml = new XElement("x", new XElement("y", "sds")); return xml.CreateNavigator(); } private IXPathNavigable GetXmlDocumentXml() { var xml = new XmlDocument(); xml.LoadXml("<x><y>sds</y></x>"); return xml.CreateNavigator(); }

  • json_encode with mysql content and umlauts in utf-8

    - by i3rutus
    Hey, i feel my beard growing while trying to find out the Problem here. Basic the Problem is, that Umlauts/Special Signs äöß ... don't work. I guess everyone is sick and tired of that questions but all the solutions found online don't seem to work. Im having utf-8 content in a utf-8 Mysql Database. I feel the Problem ist somewhere in the Database connection but i just can't figure out. character_set_client utf8 character_set_connection utf8 character_set_database utf8 character_set_filesystem binary character_set_results utf8 character_set_server latin1 character_set_system utf8 Im not sure if the problem is the latin1 for character_set_server because im not into that mysql stuff. I also dont know how to change cause i can't access the mysql server's config files. Whatever is confusing me, that if i get my results from the Database and echo it, print_r gives the right result. ini_set('default_charset','utf-8'); header('Content-Type: text/plain; > charset=utf-8'); Firefox says char encode is utf-8 but if when i output: print_r($listnew); echo json_encode($listnew[5]); print_r results everything right but json_encode does wrong. print_r: [5] => Array ( [id] => 5 [data] => U-Bahnhof Theresienstraße [size] => 17 ) json_encode: {"id":5,"data":"U-Bahnhof Theresienstra\u00dfe","size":17} i know json_encode needs a utf-8 string to work properly there and i feel im having a encode trouble here but i just can't firgure out where it is. Any help would be appreciated, thanks in advance. i3

  • Rotate UIViewController to counteract changes in UIInterfaceOrientation

    - by Peter Hajas
    Hi there, I've been searching a lot on this, and can't find anything to help me. I have a UIViewController contained within another UIViewController. When the parent UIViewController rotates, say from Portrait to LandscapeLeft, I want to make it look as though the child didn't rotate. That is to say. I want the child to have the same orientation to the sky regardless of the parent's orientation. If it has a UIButton that's upright in Portrait, I want the right-side of the button to be "up" in UIInterfaceOrientationLandscapeLeft. Is this possible? Currently, I'm doing really gross stuff like this: -(void) rotate:(UIInterfaceOrientation)fromOrientation: toOr:(UIInterfaceOrientation)toOrientation { if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationLandscapeRight)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationLandscapeLeft))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationLandscapeLeft)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationLandscapeRight))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationLandscapeRight)) || ((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationLandscapeLeft))) { } } which seems like a perfectly good waste of code. Furthermore, I was planning on using CGAffineTransform (like cited here: http://www.crystalminds.nl/?p=1102) but I'm confused about whether I should change the view's dimensions to match what they will be after the rotation. The big nightmare here is that you have to keep track of a global "orientation" variable. If you don't, the illusion is lost and the ViewController is rotated into whatever. I could really use some help on this, thanks!

  • What tools/techniques can benefit a solo developer?

    - by Michael Runyon
    Hello, I am a solo developer, working in a very small web development firm. There is occasional support for development from contractors, but for the most part, if code is written in the office, I am writing it. Many of the articles and such on here talk extensively about the tools and techniques used for collaboration of developers in teams, but that is a non-issue with me, as there is no one to (technically) collaborate with. Yet, I feel that in many ways, there are things that could be adjusted for efficiency. Our small office doesn't participate in many of the meetings/team constructions that most of the techniques rely heavily upon....we mostly just walk around and talk to one another when something is needed. This works great for all of the Just-In-Time, 15 minute fix stuff that probably populates 50% of my day, but I am also constantly working on major projects that require my total concentration, and between a flurry of tiny fixes, and being the primary admin on the 4-6 servers that we own, I find it almost impossible to get real, heavy lifting done. What suggestions can you some of you offer to help me/us become more productive/efficient, without adopting all of the corporate/teamwork practices that we are trying desperately to avoid? At what cost for efficiency is our total relaxation?

  • Cannot convert IAsyncResult to AsyncResult when using a service refrence

    I have a WCF service running, I added a reference to the service by using Add Service Reference in the solution explorer, and I checked the box for create asynchronous operations. My call works fine, I have a two way channel that reports back some events from the server and I am receiving the events. However, when the asynchronous task finishes in my callback handeler I get the error Unable to cast object of type 'SendAsyncResult' to type 'System.Runtime.Remoting.Messaging.AsyncResult'.

  • Parallel WCF calls to multiple servers

    - by gregmac
    I have a WCF service (the same one) running on multiple servers, and I'd like to call all instances in parallel from a single client. I'm using ChannelFactory and the interface (contract) to call the service. Each service has a local <endpoint> client defined in the .config file. What I'm trying to do is build some kind of generic framework to avoid code duplication. For example a synchronous call in a single thread looks something like this: Dim remoteName As String = "endpointName1" Dim svcProxy As ChannelFactory(Of IMyService) = New ChannelFactory(Of IMyService)(remoteName) Try svcProxy.Open() Dim svc As IMyService = svcProxy.CreateChannel() nodeResult = svc.TestRemote("foo") Finally svcProxy.Close() End Try The part I'm having difficulty with is how to specify and actually invoke the actual remote method (eg "TestRemote") without having to duplicate the above code, and all the thread-related stuff that invokes that, for each method. In the end, I'd like to be able to write code along the lines of (consider this psuedo code): Dim results as Dictionary(Of Node, ExpectedReturnType) results = ParallelInvoke(IMyService.SomeMethod, parameter1, parameter2) where ParallelInvoke() will take the method as an argument, as well as the parameters (paramArray or object() .. whatever) and then go run the request on each remote node, block until they all return an answer or timeout, and then return the results into a Dictionary with the key as the node, and the value as whatever value it returned. I can then (depending on the method) pick out the single value I need, or aggregate all the values from each server together, etc. I'm pretty sure I can do this using reflection and InvokeMember(), but that requires passing the method as a string (which can lead to errors like calling a non-existing method that can't be caught at compile time), so I'd like to see if there is a cleaner way to do this. Thanks

  • Extract known pattern substring from NSString (without regex)

    - by d11wtq
    I'm really tempted to drop RegexKit (or my own libpcre wrapper) into my project in order to do this, but before I do that I want to know how Cocoa developers manage to do half of this basic stuff without really convoluted code or without linking with RegexKit or another regular expression library. I find it gobsmacking that Cocoa does not include any regular expression matching features. I've so accustomed to using regular expressions for all kinds of things that I'm lost without them. I can do what I need without them, but the code would be rather convoluted. So, Cocoa devs, I ask you, what's the "Cocoa way" to do this... The problem is an everyday problem in programming as far as I'm concerned. Cocoa must have ways of doing this with the built-in features. Note that the position of the elements I want to match changes, and sometimes "quotes" are present. Whitespace is variable. Take the following strings: Content-Type: application/xml; charset=utf-8 Content-Type: text/html; charset="iso-8859-1" Content-Type: text/plain; charset=us-ascii Content-Type: text/plain; name="example.txt"; charset=utf-8 From all of these strings, how would you go about determining the mime type (e.g. text/plain) and the charset (e.g. utf-8) using just the built-in Cocoa classes? I'd end up performing a series of -rangeOfString: and substring calls, with conditional checks to deal with the optional quotes etc. Is there a way to do this with NSScanner? The NSScanner class seems to have a pretty naive API to me. Something like C's sscanf() that works for NSString objects would be an ideal fit. Most of my string parsing needs are simple such as this example so maybe regular expressions, while I'm accustomed to them, are overkill?

  • Import error ft2font from matplotlib (python, macosx)

    - by Tomas K
    I was installing matplotlib to use basemap today when I had to install a lot of stuff to make it work. After installing matplotlib and be able to import it I installed basemap but I can't import basemap because of this error: from mpl_toolkits.basemap import Basemap Traceback (most recent call last): File "", line 1, in File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/mpl_toolkits/basemap/init.py", line 36, in from matplotlib.collections import LineCollection File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/collections.py", line 22, in import matplotlib.backend_bases as backend_bases File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/backend_bases.py", line 38, in import matplotlib.widgets as widgets File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/widgets.py", line 16, in from lines import Line2D File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/lines.py", line 23, in from matplotlib.font_manager import FontProperties File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/font_manager.py", line 52, in from matplotlib import ft2font ImportError: dlopen(/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so, 2): Symbol not found: _FT_Attach_File Referenced from: /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so Expected in: dynamic lookup So when I tried to import ft2font in python by: from matplotlib import ft2font I got this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so, 2): Symbol not found: _FT_Attach_File Referenced from: /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so Expected in: dynamic lookup Any idea what to do?

  • How to dynamically set control IDs inside a repeater template?

    - by Bryan
    Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this: <asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound"> <ItemTemplate> <li id="id?"> All the other stuff </li> </ItemTemplate> </asp:Repeater> The question... is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.

  • file layout and setuptools configuration for the python bit of a multi-language library

    - by dan mackinlay
    So we're writing a full-text search framework MongoDb. MongoDB is pretty much javascript-native, so we wrote the javascript library first, and it works. Now I'm trying to write a python framework for it, which will be partially in python, but partially use those same stored javascript functions - the javascript functions are an intrinsic part of the library. On the other hand, the javascript framework does not depend on python. since they are pretty intertwined it seems like it's worthwhile keeping them in the same repository. I'm trying to work out a way of structuring the whole project to give the javascript and python frameworks equal status (maybe a ruby driver or whatever in the future?), but still allow the python library to install nicely. Currently it looks like this: (simplified a little) javascript/jstest/test1.js javascript/mongo-fulltext/search.js javascript/mongo-fulltext/util.js python/docs/indext.rst python/tests/search_test.py python/tests/__init__.py python/mongofulltextsearch/__init__.py python/mongofulltextsearch/mongo_search.py python/mongofulltextsearch/util.py python/setup.py I've skipped out a few files for simplicity, but you get the general idea; it' a pretty much standard python project... except that it depends critcally ona whole bunch of javascript which is stored in a sibling directory tree. What's the preferred setup for dealing with this kind of thing when it comes to setuptools? I can work out how to use package_data etc to install data files that live inside my python project as per the setuptools docs. The problem is if i want to use setuptools to install stuff, including the javascript files from outside the python code tree, and then also access them in a consistent way when I'm developing the python code and when it is easy_installed to someone's site. Is that supported behaviour for setuptools? Should i be using paver or distutils2 or Distribute or something? (basic distutils is not an option; the whole reason I'm doing this is to enable requirements tracking) How should i be reading the contents of those files into python scripts?

  • How can I debug why this click handler never fires?

    - by tixrus
    I am going to be excrutiatingly detailed here. I am using Firefox 3.6.3 on Max OSX with Firebug 1.5.3. I have two versions of a project, one which works and one with a bug. One I downloaded and one I typed by hand. Take a guess which one doesn't work. They should be the same except that mine uses a newer version of jQuery and the files are named differently. jQuery version is not the issue. I made mine use the older jquery and I made the working one use the newer jquery. Either way, mine still broke and the downloaded one still works. I've busted my eyes trying to see how these projects are different. The only thing I don't want to do is copy the working code to the busted code because I need to be able to figure this stuff out when it is my own unique code causing similar issues. There are no errors that I can see in Firebug in my code, in fact, 2/3 of it works just fine. just the second button does nothing. So I wanted to step through. These are always eyeball errors and I really suck at seeing them. I put it on a public server. http://colleenweb.com/jqtests/ex71.html And I want to debug ex71.js If you firebug the working one and set a break point at line 13 in ex71.js the variable json has the expected values when you click on the second button. But If you firebug this one, it never gets there. I've been over the html and all the names of everything seem to match up. I also wonder why the buttons aren't right justified but that's a css thing. Please tell me what I'm missing, and more importantly, what tool/technique I could use to find these types of bugs.

  • Using NSURLRequest to pass key-value pairs to PHP script with POST

    - by Ralf Mclaren
    Hi, I'm fairly new to objective-c, and am looking to pass a number of key-value pairs to a PHP script using POST. I'm using the following code but the data just doesn't seem to be getting posted through. I tried sending stuff through using NSData as well, but neither seem to be working. NSDictionary* data = [NSDictionary dictionaryWithObjectsAndKeys: @"bob", @"sender", @"aaron", @"rcpt", @"hi there", @"message", nil]; NSURL *url = [NSURL URLWithString:@"http://myserver.com/script.php"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[NSData dataWithBytes:data length:[data count]]]; NSURLResponse *response; NSError *err; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; NSLog(@"responseData: %@", content); This is getting sent to this simple script to perform a db insert: <?php $sender = $_POST['sender']; $rcpt = $_POST['rcpt']; $message = $_POST['message']; //script variables include ("vars.php"); $con = mysql_connect($host, $user, $pass); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("mydb", $con); mysql_query("INSERT INTO php_test (SENDER, RCPT, MESSAGE) VALUES ($sender, $rcpt, $message)"); echo "complete" ?> Any ideas?
