• WCF Service Impersonation

  - by robalot

  Good Day Everyone... Apparently, I'm not setting-up impersonation correctly for my WCF service. I do NOT want to set security on a method-by-method basis (in the actual code-behind). The service (at the moment) is open to be called by everyone on the intranet. So my questions are… Q: What web-config tags am I missing? Q: What do I need to change in the web-config to make impersonation work? The Service Web.config Looks Like... <configuration> <system.web> <authorization> <allow users="?"/> </authorization> <authentication mode="Windows"/> <identity impersonate="true" userName="MyDomain\MyUser" password="MyPassword"/> </system.web> <system.serviceModel> <services> <service behaviorConfiguration="wcfFISH.DataServiceBehavior" name="wcfFISH.DataService"> <endpoint address="" binding="wsHttpBinding" contract="wcfFISH.IFishData"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="wcfFISH.DataServiceBehavior"> <serviceMetadata httpGetEnabled="false"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration>

• MySQL Grant Problem

  - by Joel Dare

  Why might the following grant statement fail to work? grant all on kylie.* to 'kylie'@'localhost' identified by 'foo'; Here's the complete output. $ mysql -A Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 63 Server version: 5.1.37 Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> show databases like 'kylie%'; +-------------------+ | Database (kylie%) | +-------------------+ | kylie | +-------------------+ 1 row in set (0.00 sec) mysql> grant all on kylie.* to 'kylie'@'localhost' identified by 'foo'; Query OK, 0 rows affected (0.02 sec) mysql> exit Bye $ mysql -u kylie ERROR 1045 (28000): Access denied for user 'kylie'@'localhost' (using password: YES) It seems that these grant options get me every time. I think I have them memorized and the docs seem to check out too, but they often fail to work. What am I missing?

• NSFetchedResultsController not updating UITableView's section indexes

  - by Luther Baker

  I am populating a UITableViewController with an NSFetchedResultsController with results creating sections that populate section headers and a section index. I am using the following method to populate the section index: - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { return [fetchedResultsController_ sectionIndexTitles]; } and now I've run into a problem. When I add a new element to the NSManagedObjectContext associated with the NSFetchedResultsController, the new element is saved and appropriately displayed as a cell in the UITableView ... except for one thing. If the new element creates a new SECTION, the new section index does not show up in the right hand margin unless I pop the UINavigationController's stack and reload the UITableViewController. I have conformed to the NSFetchedResultsControllerDelegate's interface and manually invoke [self.tableView reloadSectionIndexTitles]; at the end of both these delegate methods: controller:didChangeSection... controller:didChangeObject... and while I can debug and trace the execution into the methods and see the reload call invoked, the UITableView's section index never reflects the section changes. Again, the data shows up - new sections are physically visible (or removed) in the UITableView but the section indexes are not updated. Am I missing something?

• How to compile a schema that uses a DataSet (xs:schema)?

  - by Yaron Naveh

  I have created the simplest web service in c#: public void AddData(DataSet ds) The generated schema (Wsdl) looks like this: <s:schema xmlns:s="http://www.w3.org/2001/XMLSchema"> ... <s:element ref="s:schema" /> ... </s:schema> Note the schema does not contain any import/include elements. I am trying to load this schema to a c# System.Xml.XmlSchema and add it to System.Xml.XmlSchemaSet: var set = new XmlSchemaSet(); var fs = new FileStream(@"c:\temp\schema.xsd", FileMode.Open); var s = XmlSchema.Read(fs, null); set.Add(s); set.Compile(); The last line throws this exception: The 'http://www.w3.org/2001/XMLSchema:schema' element is not declared. It kind of makes sense: The schema generated by .Net uses the "s:schema" type which is declared in a schema which is not imported. Why does .Net create a non valid schema? How to compile the schema anyway? Whay I did is download the schema in http://www.w3.org/2001/XMLSchema and added it to the XmlSchemaSet also. This did not work since that online schema contains DTD definition. I had to manually remove it and now all works. Does this make sense or am I missing something?

• UDK SettingsScene variable

  - by Ricket

  I am in the process of porting a script from UT3 to UDK. The script is for class ZOUIFrontEnd_MainMenu extends UTUIFrontEnd_MainMenu. I'm getting the following compiler error: C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZOUIFrontEnd_MainMenu.uc(18) : Error, Bad or missing expression in Call to 'OpenSceneByName', parameter 1 The referenced line is as follows: OpenSceneByName(SettingsScene); Okay, so I figured the OpenSceneByName function changed in UDK. Tracing the path of inheritance all the way up to UDKUIScene.uc, I found the definition: function UIScene OpenSceneByName(string SceneToOpen, bool bSkipAnimation=false, optional delegate<OnSceneActivated> SceneDelegate=None) Assuming SettingsScene is a string, everything looks fine, right? So I figured I would find SettingsScene to make sure it's a string. Well doing a search for "SettingsScene" in all files turned up only one other line; UTGameReplicationInfo.uc line 334: UTPC.OpenUIScene(class'UTUIFrontEnd_MainMenu'.default.SettingsScene); But UTUIFrontEnd_MainMenu doesn't have a SettingsScene variable in it! Just to check, I changed my line of code to match: OpenSceneByName(class'UTUIFrontEnd_MainMenu'.default.SettingsScene); And indeed, I get the following compile error now: C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZOUIFrontEnd_MainMenu.uc(18) : Error, Unknown Property 'SettingsScene' in 'Class UTGame.UTUIFrontEnd_MainMenu' How does UTGameReplicationInfo.uc successfully compile? Where is the SettingsScene variable?

• Parsing XML with jQuery... problem retrieving elements

  - by Don

  An XML snippet: <results> <review> <api_detail_url>http://api.giantbomb.com/review/1/</api_detail_url> <game> <api_detail_url>http://api.giantbomb.com/game/20462/</api_detail_url> <id>20462</id> <name>SingStar</name> </game> <score>4</score> </review> </results> And here's my testing code, just to show whether data is being collected or not ('data' holds the XML): var element; $(data).find('review').each(function() { element = $(this).find('name').text(); }); alert(element); Now here's the problem, only this query actually returns data: $(this).find('score').text(); The alert box in this case would pop up with '4'. These two other queries don't return anything (the alert box is blank): $(this).find('api_detail_url').text(); $(this).find('name').text(); I've tried using jQuery selectors, like... $(this).find('game > name').text(); ...but that doesn't work, either, still get a blank alert box. Am I missing something? Testing is being done in Chrome.

• Please help! request compression

  - by Naor

  Hi, I wrote an IHttpModule that compress my respone using gzip (I return a lot of data) in order to reduce response size. It is working great as long as the web service doesn't throws an exception. In case exception is thrown, the exception gzipped but the Content-encoding header is disappear and the client doesn't know to read the exception. How can I solve this? Why the header is missing? I need to get the exception in the client. Here is the module: public class JsonCompressionModule : IHttpModule { public JsonCompressionModule() { } public void Dispose() { } public void Init(HttpApplication app) { app.BeginRequest += new EventHandler(Compress); } private void Compress(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpRequest request = app.Request; HttpResponse response = app.Response; try { //Ajax Web Service request is always starts with application/json if (request.ContentType.ToLower(CultureInfo.InvariantCulture).StartsWith("application/json")) { //User may be using an older version of IE which does not support compression, so skip those if (!((request.Browser.IsBrowser("IE")) && (request.Browser.MajorVersion <= 6))) { string acceptEncoding = request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(acceptEncoding)) { acceptEncoding = acceptEncoding.ToLower(CultureInfo.InvariantCulture); if (acceptEncoding.Contains("gzip")) { response.AddHeader("Content-encoding", "gzip"); response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); } else if (acceptEncoding.Contains("deflate")) { response.AddHeader("Content-encoding", "deflate"); response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress); } } } } } catch (Exception ex) { int i = 4; } } } Here is the web service: [WebMethod] public void DoSomething() { throw new Exception("This message get currupted on the client because the client doesn't know it gzipped."); } I appriciate any help. Thanks!

• - (void)keyboardWasShown not called when switching to another UITextField

  - by Shawn

  I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

• Windows-mobile app won't run after being closed by Task Manager

  - by pithyless

  I've inherited some windows-mobile code that I've been bringing up-to-date. I've come across a weird bug, and I was hoping that even though a bit vague, maybe it will spark someone's memory: Running the app (which is basically a glorified Forms app with P/Invoke gps code), I switch to the task manager, and close the app via End Task. Seems to exit fine (no errors and disappears from Task Manager). Unfortunately, the app refuses to start a second time until I reboot the phone or reinstall the CAB. What's worse: this bug is reproducible on a HTC Diamond, but works fine (ie. can run again after EndTask) on an HTC HD2. The only thing I can think of is some kind of timing race between a Dispose() and the Task Manager. Any ideas? I'm also thinking of a workaround - I do have a working "Exit Application" routine that correctly cleans up the app; can I catch the EndTask event in the c# code in order to complete a proper cleanup? Maybe I'm just missing the pain point... all ideas welcome :)

• Java and tomcat vs ASP.NET and IIS

  - by Mark Cooper

  Until recently I'd considered myself to be a pretty good web programmer (coming up for 10yrs commercial experience on a variety of e-commerce, static and enterprise applications). I'm self taught and have always used the Microsoft product stack (ASP, ASP.NET)... My applications are always functional, relatively bug free, but have never been lightening quick. As a frequent web user I always found this to be the norm... how fast are the websites from the big tech players (eBay, Facebook, Microsoft, IBM, Dell, Telerik etc etc) - in truth none are particularly fast. I always attributed this to "the way things are with web apps"... ...then I cam across a product called Jira from atlasian and this has stopped me in my tracks... This application is fast, and I mean blindingly fast.. too fast to time the switches between pages, fully live content, lots of images and data and cross references etc etc... I run this on an intranet, with a large application DB, and this is running on a very normal server (single processor, SATA HDD, 8GB RAM). Am I missing something?? Are my programming techniques that bad?? I am wondering if this speed gain is down to it being written in Java and running on Tomcat. Does anyone have any benchmarks to compare JSP / ASP or Tomcat / IIS??? Thanks, Mark NOTE: this isn't a blatant plug for Jira. I don't work for them or have any affiliation to them... but I would like to be able to write applications like them :)

• Navigating between pages in a Facebook Platform iframe application

  - by Jimmy Cuadra

  I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

• Packaging a qt application compiled with shared libraries

  - by Surjya Narayana Padhi

  Hi Geeks, I downloaded the qt embedded demo source code recently on my linux machine. Following are the outcomes during running of the program I compiled it statically on my x86 machine and run the application on x86 machine it runs fine. But when i took the statically compiled binary file to other machine with Atom platform It run with some missing widgets. I found that the plugins cant be ported with static compilation. Can anybody tell me is it true? If no can anybody tell me the steps for it? I compiled it dynamically with shared libraries. Then got an executalbe on linux. I did "ldd MyAppName". It show me the shared library files it is using. But I dont know how to package these. Can anybody tell me the steps to package it? I checked in the article on deploying qt applications on X11-linux platforms. But its not complete. Can anybody give me the detailed steps? Any help will be appreciated......

• Android: ListActivity design - changing the content of the List Adapter

  - by Rob

  Hi, I would like to write a rather simple content application which displays a list of textual items (along with a small pic). I have a standard menu in which each menu item represents a different category of textual items (news, sports, leisure etc.). Pressing a menu item will display a list of textual items of this category. Now, having a separate ListActivity for each category seems like an overkill (or does it?..) Naturally, it makes much more sense to use one ListActivity and replace the data of its adapter when each category is loaded. My concern is when "back" is pressed. The adapter is loaded with items of the current category and now I need to display list of the previous category (and enable clicking on list items too...). Since I have only one activity - I thought of backup and load mechanism in onPause() and onResume() functions as well as making some distinction whether these function are invoked as a result of a "new" event (menu item selected) or by a "back" press. This seems very cumbersome for such a trivial usage... Am I missing something here? Thanks, Rob

• How to create X509 self signed certificate for use in Apache Tomcat

  - by DaveJohnston

  I have a Java application that runs on Windows Mobile devices using a 3rd Party JVM. The application communicates with an Apache Tomcat server over HTTP. We have also used HTTPS for some connections and the certificates were created using the Sun keytool utility. First a keystore was created using genkey, then the certificate exported using export and finally that was imported into another keystore using import. The file created by genkey was loaded into the Apache server and the keystore created using import was loaded into the JVM on the PDA. Everything works as expected. I am now working with a new JVM on the PDA and (for whatever reason) I have established that this JVM requires the keystore to be in X509 (DER) format. I started working on this about a month ago and had it working, but stupidly never wrote down the steps I took, and now I can't for the life of me remember what I did. I seem to remember using openssl but other than that I am totally lost. Anything I create now using openssl and try to load into Apache causes an error at startup (Invalid Keystore Format) so I am probably missing something out entirely. Does anyone have any ideas how I should be going about creating this self-signed X509 certificate that can be loaded into Apache server and JVM running on a PDA?

• Which itch does a gravatar scratch?

  - by WizardOfOdds

  This is a very serious question: I've seen lots of threads here about gravatars but I couldn't find and answer to this question: what computer identification/authentication (?) problem, if any, are gravatars supposed to solve? Neither the Wikipedia entry nor the official website are very useful. The official website mentions a "globally unique" picture. Unique in what sense? As far as I can see it's only the hash that is unique: two persons can have two pictures looking very similar if not identical. Note that this question is not about which problems do gravatars unarguably cause (like leaking 10% of the stackoverflow.com accounts email addresses like discussed here : "gravatars can leak email adresses" ) but about which authentication (?) problems, if any, are gravatars supposed to solve? Is the goal just to have a cool/funny/cute icon and save bandwith by having it stored on a remote website or is there more to it, like serving a real authentication purpose which I'd be completely missing? Note that I've got nothing against them and find them rather cool, but I'm just having a hard time figuring out what their purpose is and if I should care or not about them in the webapps I'm developping.

• DDMS won't load (or doesn't parse?) KML file

  - by nderraugh

  I can't get DDMS to load any KML files. I have a KML file for example with the following in it: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Placemark> <name>Simple placemark</name> <description>Attached to the ground. Intelligently places itself at the height of the underlying terrain.</description> <Point> <coordinates>-122.0822035425683,37.42228990140251,0</coordinates> </Point> </Placemark> </kml> The docs at http://developer.android.com/guide/developing/tools/ddms.html seem to indicate that I only need to launch my app and fire up DDMS and load the KML. That doesn't work. I even tried the Google Earth solution suggested at the same link. I'm using SDK 1.5_r2. I am doing something wrong or missing something?

• Manditory read-only fields in django

  - by jamida

  I'm writing a test "grade book" application. The models.py file is shown below. class Student(models.Model): name = models.CharField(max_length=50) parent = models.CharField(max_length=50) def __unicode__(self): return self.name class Grade(models.Model): studentId = models.ForeignKey(Student) finalGrade = models.CharField(max_length=3) I'd like to be able to change the final grade for several students in a modelformset but for now I'm just trying one student at a time. I'm also trying to create a form for it that shows the student name as a field that can not be changed, the only thing that can be changed here is the finalGrade. So I used this trick to make the studentId read-only. class GradeROForm(ModelForm): studentId = forms.ModelChoiceField(queryset=Student.objects.all()) def __init__(self, *args, **kwargs): super(GradeROForm,self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.id: self.fields['studentId'].widget.attrs['disabled']='disabled' def clean_studentId(self): instance = getattr(self,'instance',None) if instance: return instance.studentId else: return self.cleaned_data.get('studentId',None) class Meta: model=Grade And here is my view: def modifyGrade(request,student): student = Student.objects.get(name=student) mygrade = Grade.objects.get(studentId=student) if request.method == "POST": myform = GradeROForm(data=request.POST, instance=mygrade) if myform.is_valid(): grade = myform.save() info = "successfully updated %s" % grade.studentId else: myform=GradeROForm(instance=mygrade) return render_to_response('grades/modifyGrade.html',locals()) This displays the form like I expect, but when I hit "submit" I get a form validation error for the student field telling me this field is required. I'm guessing that, since the field is "disabled", the value is not being reported in the POST and for reasons unknown to me the instance isn't being used in its place. I'm a new Django/Python programmer, but quite experienced in other languages. I can't believe I've stumbled upon such a difficult to solve problem in my first significant django app. I figure I must be missing something. Any ideas?

• Reloading Sinatra app on every request on Windows

  - by Darth

  I've set up Rack::Reload according to this thread # config.ru require 'rubygems' require 'sinatra' set :environment, :development require 'app' run Sinatra::Application # app.rb class Sinatra::Reloader < Rack::Reloader def safe_load(file, mtime, stderr = $stderr) if file == Sinatra::Application.app_file ::Sinatra::Application.reset! stderr.puts "#{self.class}: reseting routes" end super end end configure(:development) { use Sinatra::Reloader } get '/' do 'foo' end Running with thin via thin start -R config.ru, but it only reloads newly added routes. When I change already existing route, it still runs the old code. When I add new route, it correctly reloads it, so it is accessible, but it doesn't reload anything else. For example, if I changed routes to get '/' do 'bar' end get '/foo' do 'baz' end Than / would still serve foo, even though it has changed, but /foo would correctly reload and serve baz. Is this normal behavior, or am I missing something? I'd expect whole source file to be reloaded. The only way around I can think of right now is restarting whole webserver when filesystem changes. I'm running on Windows Vista x64, so I can't use shotgun because of fork().

• Sharepoint.OpenDocuments Control Compatible with Forms Authentication?

  - by Richard Collette

  We are using the Sharepoint.OpenDocuments.EditDocument2 ActiveX control and method. The method is being called from JavaScript in an IE6 client on a Windows XP SP3 client (fully patched). The server is running IIS6 on Windows Server 2003 SP1 Fronting the IIS server is Tivoli Access Manager (TAM) which proxies access to the web applications sitting behind it. Similar to forms authentication, it creates a session cookie for authentication purposes, that must be present for the HTTP request to reach the IIS server. In front of TAM is an F5/BigIP load balancer and SSL encryption offloader, which enforces that incoming requests use the HTTPS protocol. What is happening is that HTTP requests issued by this control do not contain any session cookies that were present in the browser. It drops the ASP.NET session cookie, the ASP.NET forms authentication cookie and the TAM cookie Because the TAM cookie is missing the request is redirected to the TAM login page, which then shows up via HTML conversion in Word or Excel. The API documentation at http://msdn.microsoft.com/en-us/library/ms440037.aspx mentions nothing about security or appropriate usage scenarios for this control. Should these controls work in an ASP.Net Forms Authentication scenario or are they only supported with Windows Authentication. If Forms Authentication is supposed to function, how do we get the control to include the necessary session cookies in its requests?

• How does one use OpenFileDialog in C# in visual Studio 2010

  - by xarzu

  I have written a custom dialog (form) that I can use in a C# program that behaves much like a "File - Open" menu command and brings up a window where a user can select a file or directory. The question I have is this. It has "My Computer" as its root. How can I have it so that it searches on a Network? If the file or directory is located on a network. Or better yet, in Visual Studio 2010, is there some sort of canned FileOpenDialog that I can use right away? I tried calling the OpenFileDialog as described in the example code at http://msdn.microsoft.com/en-us/library/system.windows.forms.openfiledialog.aspx but the compiler does not seem to like DialogResult.OK as used in this line of code: if(openFileDialog1.ShowDialog() == DialogResult.OK) The compiler says: Error 1 'System.Nullable' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable' could be found (are you missing a using directive or an assembly reference?) I tried using the namespace Microsoft.Win32 instead of System.Windows.Forms and neither worked. They both produced this error.

• How to resize a Flot graph when its containing div changes size

  - by Will Gorman

  I'm using the Flot graphing library jQuery plugin and I haven't found a good way to handle resizing the graph when it's containing <div> changes size (for example, due to window resizing). When handling the onresize event, I've made sure that the width and height of the containing <div>are updated to the correct size and then tried calling both setupGrid and draw on the plot object but with no effect. I've had some success with the approach of just removing and readding the containing <div> and replotting the graph in it. However, this seems to be prone to getting stuck in infinite resize event loops if I have to add other <div> elements to the document at the same time (like for tooltips for the graph) as I'm guessing those can trigger resize events as well? Is there a good way to handle it that I'm missing? (I'm also using ExplorerCanvas for IE in order to be able to use Flot, if that might have anything to do with it. I haven't really tried in any other browsers yet)

• Cocoa Virtual Keystrokes Pain

  - by bhargav

  I'm writing an application to respond on a hotkey by copying highlighted text into NSPasteboard's generalPasteboard. After looking around here for a solution for sending virtual keystrokes, I found this: http://stackoverflow.com/questions/1505933/how-to-send-a-cmd-c-keystroke-to-the-active-application-in-objective-c-or-tell I tried the applescript suggested with NSAppleScript: NSLog(@"Hotkey Pressed"); NSPasteboard *pasteboard = [NSPasteboard generalPasteboard]; NSAppleScript *playScript; playScript = [[NSAppleScript alloc] initWithSource:@"tell application \"System Events\" to keystroke \"c\" using command down"]; if([playScript isCompiled] == NO){ [playScript compileAndReturnError:nil]; } id exerror = [playScript executeAndReturnError:nil]; if(exerror == nil){ NSLog(@"Script Failed"); } It works, but only on the first time I hit the hotkey. Each subsequent hit will not to grab the highlighted text. The generalPasteboard still contains the same contents as before the script is run again. Clearing the generalPasteboard before I run the code is no use, because then the code fails when attempting to read the pasteboard contents. So I tried the next suggested solution: CFRelease(CGEventCreate(NULL)); CGEventRef event1, event2, event3, event4; event1 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)50, true); event2 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)8, true); event3 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)8, false); event4 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)50, false); CGEventPost(kCGHIDEventTap, event1); CGEventPost(kCGHIDEventTap, event2); CGEventPost(kCGHIDEventTap, event3); CGEventPost(kCGHIDEventTap, event4); The above should send the keystrokes Command + c, but all I get is a beep, and the pasteboard contents are unchanged. I'm at wits end - can anyone enlighten me as to what I'm missing or point me out to what I'm overlooking for something so simple?

• ASP MVC Ajax Controller pattern?

  - by Kevin Won

  My MVC app tends to have a lot of ajax calls (via JQuery.get()). It's sort of bugging me that my controller is littered with many tiny methods that get called via ajax. It seems to me to be sort of breaking the MVC pattern a bit--the controller is now being more of a data access component then a URI router. I refactored so that I have my 'true' controller for a page just performing standard routing responses (returing ActionResponse objects). So a call to /home/ will obviously kick up the HomeController class that will respond in the canonical controller fashion by returning a plain-jane View. I then moved my ajax stuff into a new controller class whose name I'm prefacing with 'Ajax'. So, for example, my page might have three different sections of functionality (say shopping cart or user account). I have an ajax controller for each of these (AjaxCartController, AjaxAccountController). There is really nothing different about moving the ajax call stuff into its own class--it's just to keep things cleaner. on client side obviously the JQuery would then use this new controller thusly: //jquery pseudocode call to specific controller that just handles ajax calls $.get('AjaxAccount/Details'.... (1) is there a better pattern in MVC for responding to ajax calls? (2) It seems to me that the MVC model is a bit leaky when it comes to ajax--it's not really 'controlling' stuff. It just happens to be the best and least painful way of handling ajax calls (or am I ignorant)? In other words, the 'Controller' abstraction doesn't seem to play nice with Ajax (at least from a patterns perspective). Is there something I'm missing?
