• HTTP Error 500.19 - Internal Server Error for silverlight application

  - by KentZhou

  Use VS2010 silverlight business application template to createa defaut solution. Change authentication to Windows in Web.config and the code in app.xaml.cs to use windows authentication. Nothing else changed. Then run this app from vs2010 built-in web server, it is fine, I can see the login user info from windws(from a AD domain account) display on the top-right of the screen, like DomainName\userName. Then deploy this web app to IIS on windows 7(same computer) and access this app again, I got following error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

• How to return model state from child action handler in ASP.NET MVC

  - by Joe Future

  In my blog engine, I have one controller action that displays blog content, and in that view, I call Html.RenderAction(...) to render the "CreateComment" form. When a user posts a comment, the post is handled by the comment controller (not the blog controller). If the comment data is valid, I simply return a Redirect back to the blog page's URL. If the comment data is invalid (e.g. comment body is empty), I want to return the ViewData with the error information back to the blog controller and through the blog view to the CreateComment action/view so I can display which fields are bad. I have this working fine via AJAX when Javascript is enabled, but now I'm working on the case where Javascript might be disabled. If I return a RedirecToAction or Redirect from the comment controller, the model state information is lost. Any ideas?

• Listening to the iPhone mic with SCListener and playing music at the same time: how?

  - by Eamon Ford

  Hello, I am using Stephen Celis' SCListener class (for iPhone) to "listen" from the microphone, but I also need to be playing music at the same time using the MediaPlayer framework. However, when I start listening with SCListener, the music fades out and stops. I have set the kAudioSessionCategory_PlayAndRecord property on the audio session in SCListener, which should allow me to play audio and record audio at the same time, but as far as I can tell it has no effect. I'm confused, because according to other developers' results, this works just fine, but not for me. I'm thinking maybe the kAudioSessionCategory_PlayAndRecord property allows you to play sound and record if you're using the AVAudioPlayer framework or something to play the sound, but maybe not the MediaPlayer framework? This would be a problem for me because I need to play music from the user's iPod library, which, as far as I know is only possible to do using the MediaPlayer framework. Does anyone know how I can get around this problem? Thanks in advance!

• Why does TheyWorkForYou (TWFY) web API always returns '{}'

  - by Tartley

  I'm calling a web API exposed by TheyWorkForYou (TWFI). http://www.theyworkforyou.com/api/ I'm using the Python bindings provided by twfython: http://code.google.com/p/twfython/ I wrote some code to call this API a few months ago, at which time it worked fine. But now I dig it out to run it again, no matter what query I ask of the API, it always returns '{}' (an empty dictionary). For example the following code, which should return a list of all MPs: from twfy import TWFY API_KEY = 'XXXXXXXXXXXXXXXXXXXXXX' twfy = TWFY.TWFY(API_KEY) print twfy.api.getMPs(output='js') Am I being really dumb? What else should I check?

• open webim ( Mibew Messenger ) time out, reconnecting

  - by Senthil Kumar

  hi, i hope you guys know about webim a.k.a mibew messenger. I know only java, jsp and no idea about php except for some basics. Anyways, i ran this app in my apache2.2 local server. Everything works superb! But if i change my db to a virtual machine and give its address in the config.php (previously i had used localhost), in the visitors page, i get timeout, reconnecting. Login has no prob, so my guess is db connection is fine. I even changed the default page refresh time from 2 to 10. Nothing happens. Still same thing. You guys have any idea?

• Dynamically load nib for iPhone/iPad within view controller

  - by qui

  Hello I have converted an iPhone application using the wizard like thing in XCode into a universal app. It builds fine but obviously looks a bit rubbish in some areas :) I need to load nibs according to which device is being used. I dont wish to create my view controllers using initWithNib as I already have code to create the controllers with some data (initWithMyLovelyData) which doesnt do anything to do with nib loading. I know to find out the device you use UI_USER_INTERFACE_IDIOT() so I tried overriding the initWithNibName within the actual view controllers themselves, assuming they get called internally somehow. But it's not working as I guess I am unsure of the syntax. I have tried if(ipad..) self = [super initWithNibName:@"MyIpadNib" bundle:nibBundleOrNil]; And that doesnt work :/ EDIT - I know I have massively edited this, made my question a bit more specific after doing some more research - apologies!

• FullText Search using multiple tables in SQL

  - by Caesar

  Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?

• Issue passing NSMutableDictionary to a method

  - by roswell

  Hello all, I've got a chunk of code that's passing an NSMutableDictionary (amongst other things) to a method in another class: [self.shuttle makeAPICallAndReturnResultsUsingMode:@"login" module:@"login" query:credentials]; The NSMutableArray credentials is previously defined like this: NSMutableDictionary *credentials = [[NSMutableDictionary alloc] init]; [credentials setObject:username forKey:@"username"]; [credentials setObject:password forKey:@"password"]; The method that receives it looks like this: -(id)makeAPICallAndReturnResultsUsingMode:(NSString *)mode module:(NSString *)module query:(NSMutableDictionary *)query The code works fine up until this point within the above method: [query setObject:self.sessionID forKey:@"session_id"]; At this point, the application terminates -- the console informs me of this exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSCFDictionary setObject:forKey:]: method sent to an uninitialized mutable dictionary object' This leads me to believe that I must initialize NSMutableDictionary in some way in my new method before I can access it, but I have no idea how. Any advice?

• Returning form errors for AJAX request in Django

  - by mridang

  Hi Guys, I've been finding my way around Django and jQuery. I've built a basic form in Django. On clicking submit, I'm using jQuey to make an AJAX request to the sever to post my data. This bit seems to work fine and I've managed to save the data. Django returns a ValidatioError when a form is invalid. Could anyone tell me how to return this set of error messages as a response to my AJAX request so i can easily iterate through it using JS and do whatever? I found this snippet. Looking at the JS bit (processJson) you'll see that he seems to get the error messages by extracting them from the response HTML. It seems kinda kludgy to me. Is this a best way to go about it? My apologies for any vagueness. Thanks in advance.

• Blacklight Expander problem while expanding programmatically

  - by David Brunelle

  Hi, I am doing a silverlight project in Silverlight 4 and I included the BlackLight project in my project so that I could use their new controls, especialy the dockpanel and the autoexpander, which is causing me at the moment some little problems. What I would like to do is to have several auto-expander that will expand or collapsed when I click on button. In my case more specifically, each auto-expander have a set of parameter to fill, which in turn will fill the other expander and the current one would collaps and the just filled one would expand. The idea is simple, yet when I use a button which is on one of my expander, it only works once... It would expand/collapse the first time, then after that, nothing. I trace the code and it seems to go through just fine, but the property value won't change Here is my code Private Sub BtnExpand_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles BtnExpand.Click ClientExpander.IsExpanded = False ProjetExpander.IsExpanded = True End Sub Could it be a known bug, or must I reset some flags to make it work? Thanks.

• UISearchBar and UINavigationController

  - by Calvin L

  I have an .xib file connected to a ViewController, which is init'ed as the root controller of an instance of UINavigationController in my appDelegate. In that view, I have a UISearchBar and a UITableView below it. When the view loads up, there's a navigationBar at the top, followed by a ~20 pixel gap, and then the UISearchBar, and the table beneath it: My problem is that when I enter the UISearchBar to type something, the navigation bar disappears (which is fine), but the search box is all screwy: I'm pretty new to this (a couple of weeks), so I'm not quite sure what's going on. Can anyone help me shed some light on this?

• Python 2.7 - Help using an API (HL7)

  - by atomicluis

  I am new to programming and Python. I have a very basic python script that connects to server and send a text message: #!/usr/bin/python import socket s = socket.socket() host = '127.0.0.1' port = 4106 s.connect((host, port)) message = 'test1' s.send(message) print s.recv(1024) s.close Everything is fine, except that this message is an HL7 message and needs to wrapped in MLLP I found this API that I think can do this for me (http://python-hl7.readthedocs.org/en/latest/api.html#mllp-network-client) So I modified my program to the following, but I keep getting the error message: NameError: name 'MLLPClient' is not defined #!/usr/bin/python import socket import hl7 host = '127.0.0.1' port = 4106 with MLLPClient(host, port) as client: client.send_message('test1') print s.recv(1024) s.close Thanks in advanced for all the help

• java.security.AccessControlException: access denied using Java Web Start

  - by killiancomputers

  I am having some issues with accessing files using JWS (Java Web Start). The program adds a new label and image. The program runs fine on my local computer but gives me pages of errors when I run the program on my remote server using JWS. Here's a sample of the error: Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission add2.png read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) This occurs even after making sure the images have read access. Ideas?

• Preserving DataRowState when serializing DataSet using DataContractSerializer

  - by user349453

  For various reasons I am having to send a typed dataset to a WCF service endpoint. This works fine except that upon Deserializing, the RowState of each row in each DataTable is set to 'Added', regardless of what they were on the client. If I write the serialized stream out to a file, I see that the RowState is not part of the Serialized data. How can I add this so that I can preserve the RowState across service boundaries? Not that I think it matters, but the client process is running .net 3.5 while the service process is running .net 4.0

• Qt: Background color on QStandardItem using StyleSheet

  - by Johan

  Hi I have a class that inherits QStandardItem and I put the elements in a QTreeWidget. The class receive notifications from the outside and I want to change the background color of the item based on what happened. If I do not use stylesheets it works just fine, like this: void myClass::onExternalEvent() { setBackground(0, QColor(255,0,0))); } However as soon as I put a stylesheet on the QTreeWidget this has no effect, the stylesheet seems to override the setBackground call. So I tried : void myClass::onExternalEvent() { this-setStyleSheet("background-color: red"); } but this is probably all wrong, it changed the color of some other element on my screen, not sure why. So anyone have an idea on how I can alter the background color like with setBackgroundColor but still be able to use stylesheet on my QTreeWidget?

• Computing MD5SUM of large files in C#

  - by spkhaira

  I am using following code to compute MD5SUM of a file - byte[] b = System.IO.File.ReadAllBytes(file); string sum = BitConverter.ToString(new MD5CryptoServiceProvider().ComputeHash(b)); This works fine normally, but if I encounter a large file (~1GB) - e.g. an iso image or a DVD VOB file - I get an Out of Memory exception. Though, I am able to compute the MD5SUM in cygwin for the same file in about 10secs. Please suggest how can I get this to work for big files in my program. Thanks

• Animating a CALayer's mask size change

  - by Alexander Repty

  I have a UIView subclass which uses a CAShapeLayer mask on its CALayer. The mask uses a distinct shape, with three rounded corners and a cut out rectangle in the remaining corner. When I resize my UIView using a standard animation block, the UIView itself and its CALayer resize just fine. The mask, however, is applied instantly, which leads to some drawing issues. I've tried animating the mask's resizing using a CABasicAnimation but didn't have any luck getting the resizing animated. Can I somehow achieve an animated resizing effect on the mask? Do I need to get rid of the mask, or will I have to change something about the way I currently draw the mask (using - (void)drawInContext:(CGContextRef)ctx). Cheers, Alex

• IPC::Open3 Fails Running Under Apache

  - by rjray

  I have a module that uses IPC::Open3 (or IPC::Open2, both exhibit this problem) to call an external binary (bogofilter in this case) and feed it some input via the child-input filehandle, then reads the result from the child-output handle. The code works fine when run in most environments. However, the main use of this module is in a web service that runs under Apache 2.2.6. And under that environment, I get the error: Cannot fdopen STDOUT: Invalid argument This only happens when the code runs under Apache. Previously, the code constructed a horribly complex command, which included a here-document for the input, and ran it with back-ticks. THAT worked, but was very slow and prone to breaking in unique and perplexing ways. I would hate to have to revert to the old version, but I cannot crack this.

• How to debug a tcl script which is argument to an executable?

  - by user321047

  I have a application which takes tcl script as argument. I want to debug tcl script when the application processes it. My development environment consists of Dynamic Languages Toolkit from www.eclipse.org/dltk along with Active state remote debugger -dbgp_tcldebug. I am able to debug the individual tcl scripts with this setup. I created a tcl project in eclipse and added 'startup.tcl' and 'argumentScript.tcl' scripts and added following command to the startup script, set ExecutableName "xyz.exe" set returnValue [catch {eval exec $ExecutableName "argumentScript.tcl" } result] My debugger works fine with 'startup.tcl' script. I added the breakpoint in 'argumentScript.tcl' but it is not working. How can I debug the "argumentScript.tcl" script ? Edit: A solution without using eclipse environment is Tcl Dev Kit with remote debugging feature.

• Process.Start concatenating cmd line from previous invocation

  - by Ralph

  Hi, I am using a Process.Start in .Net 2.0 to start a child win32 app. Process.start ( "SomeProcess.exe", "<Cmd line>" ); The process runs fine but and the user then closes this window. However if I then run the same process again in the same session, the cmd line recieved by the called process is now a concatentation of the previous call. I.e SomeProcess.exe recieves the cmd line " SomeProcess.exe ". Has anyone else seen this behaviour before? Any help much appreciated. Ralph.

• BSD Sockets don't behave in a iPhone 3G environment

  - by Kyle

  I noticed that many times while developing for an iPhone 3G, BSD socket functions will simply fail. I also noticed at the time, the 3G antenna wasn't even ON, nor was there WIFI Access to back up the network call (So it seems ridiculous that it doesn't turn on to support the network request).. This information was verified with an app from Apple in the SDK called Connectivity Test, or something of the sort. Basically if you load Safari or something, then quickly load up the App it would be fine.. Of course that's not ideal. Apparently, to apple, gethostbyname() or something of the sort is by no means a reason to turn on the Antenna. I contacted Apple about this, and they said that the BSD functions do not switch the Antenna on, but calling all of the Objective-C CFNetwork functions do. I want portable code, so is there a way to keep my existing BSD setup? I really dislike coding in Objective-C, so if anyone knows a work around, that would be awesome.
