  • Headers to set for AJAX calls in a custom webserver

    - by ErJab
    I'm writing a custom web server. When I enter the URL of my server in the browser, I get the sample text I write out to the socket in my browser correctly. This is the HTTP response that I write: HTTP/1.1 200 OK\r\n Server: My Server\r\n Date: Blah\r\n \r\n This is some sample text. This appears in my browser correctly when I connect directly to the server entering the URL. However, if I use Ajax (jQuery) to access the same URL and then set the innerHTML of an element on the HTML page, I do not get any data printed. Is there any other header I need to set on my web server so that the browser's XMLHttpRequest object detects the response?

  • Facebook Connect: Error when clicking the Facebook Connect button

  • AD Password About to Expire check problem with ASP.Net

    - by Vince
    Hello everyone, I am trying to write some code to check the AD password age during a user login and notify them of the 15 remaining days.

  • JSONP callback method is not defined

    - by Micah
    I'm trying to get a jsonp callback working using jquery within a greasemonkey script. Here's my jquery: $.ajax({ url: "http://mydomain.com/MyWebService?callback=?", data: { authkey: "temphash" }, type: "get", dataType: "json", cache: false, success: function(data) { console.log(data); } }); in my webservice (asp.net) I'm returning the response with a content type of application/javascript. The response the server is actually sending back is: jsonp1276109314602({"message":"I'm getting tired of this not working"}) The jsonp1276109314602 method name is being randomly generated by jquery, and I'm grabbing it with Request.QueryString["callback"] However my success function is never called and the firebug console gives me an error saying jsonp1276109314602 is not defined. What am I doing wrong?

  • iPhone StoreKit - invalid product id's

    - by Achim
    I'm trying to test the in App purchase within the sandbox environment. In order to test the code I a) created a In App Purchase Test User account under 'Manage Users' in iTunes Connect b) created some in app purchase products under 'Manage Your In App Purchases'. I used numeric values and alpha-numeric values for the Product ID's. c) Loaded the app onto the iPhone, went to Settings-Store and logged out of the regular store and into the under a) created test account d) set a breakpoint in the (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response callback All the submitted Product ID's are in the response.invalidProductIdentifiers category. When submitting the request I use either the Product ID's used under b) directly or I tried to prefix them with the Bundle ID: NSString *id2 = @"com.super.duper.8"; NSSet *productList = [NSSet setWithObjects:id2, @"8", nil]; SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:productList]; Am I missing something obvious? Any help is appreciated. Achim

  • facebook oauth dialog doesn´t start

    - by Franz Deschler
    Hi i got the following problem: I want the user to authenticate my app, so i want to show the authorisation dialog. To do this, i tried the api function FB.api("/dialog/oauth", "get", {client_id: APP_ID, redirect_uri: URI}, function(response){ console.log(response); }); But i get this error: code: 2500 message: "Unknown path components: /oauth" type: "OAuthException" But why? The FB.api call should be the same like http://www.facebook.com/dialog/oauth?client_id=<app-id>&redirect_uri=<uri> If i put this url in the browser directly, the dialog is shown.

  • how to convert bitmap image to CIELab image?

    - by Neal Davis
    Hello to stackoverflow members! This is my first post but I love reading the questions and answers on this forum! I'm using VS2008, CSharp, NET 3.5 and Windows XP Pro latest patches on this project. I am reading in a jpeg file to a bitmap image using CSharp in the following way: Bitmap bmp = new Bitmap("background.jpg"); Graphics g = Graphics.FromImage(bmp); I then write some text and logos on g using various DrawString and DrawImage commands. I then want to write this bitmap to a tiff file using the command: bmp.Save("final_artwork.tif", ImageFormat.Tiff); I don't know what the TIFF tags in the header of the final resultant TIFF file will be when you do bmp.Save as shown above? But what I want to produce is a TIFF image file with PHOTOMETRIC CIELab, BITSPERSAMPLE 8, SAMPLESPERPIXEL 3, FILLORDER MSB2LSB, ORIENTATION TOPLEFT, PLANARCONFIG CONTIG, and also uncompressed and singlestrip. Im fairly certain, at least I have not found anything about Microsoft API and CIELab, I can not convert the bitmap image to CIELab photometric and the other requirements using anything from the Microsoft API or .NET 3.5 environment - someone please correct if I am wrong. I have used libtiff in a project in the past but just to write a tiff file where the tiff image in memory was already in CIELab format and all the other requirements as noted per above. Im not certain libtiff can convert from my CSharp bitmap image, which is probably RGB photometric, to CIELab, 8 bps, and 3 spp? Maybe I can use OpenCVImage or Emgu CV or something similiar? So the main question is what is going to be the easiest way to get my final bitmap image as outlined above into a CIELab TIFF and also meeting the other requirements per above? Thanks for any suggestions and code fragments you can provide? Neal Davis

  • Mercurial: Problem converting Windows cvs repository to mercurial

    - by jalperin
    I’m trying to convert an existing Windows CVS repository to Mercurial and getting the following response and error: C:\Windows\system32>hg convert c:\users\jeff\webs\shelter-cvs\shelter assuming destination shelter-hg initializing destination shelter-hg repository connecting to :local:c:\cvs abort: unexpected response from CVS server (expected "Valid-requests", but got 'E cvs [server aborted]: c:\\cvs: no such repository\n') Here’s the background: The repository was created with TortoiseCVS so I believe it’s actually cvsnt. I can properly checkout from the repository using either the command line or the TortoiseCVS gui, so I think it is set up correctly. I'm trying to convert a working copy, not the repository itself I’m running Windows 7, 64-bit I’ve installed TortoiseHG and enabled the convert extension.

  • How do I use Powershell to print a list of hyperlinks that appear in a Word document?

    - by dwwilson66
    I asked this question last week, and my script cannot find any hyperlinks to change. Now I'm backing up and trying to simply open a single document and list the hyperlinks within. I've verified that the document includes hyperlinks to a number of anchors in the same document, and two hyperlinks to documents in the same directory. However, either Powershell isn't finding links in the doc or I'm outputting the list to the console improperly. Here's my bare-bones code $word = New-Object -ComObject Word.Application $doc ="R:\path\Reporting_Emergency_Or_Hazardous_Situation_-_BC_CC.doc" $hyperlinks = @($doc.Hyperlinks) $hyperlinks $word.quit() or, for line 4 Write-Host $hyperlinks or, again for line 4 $hyperlinks | % {Write-Host $_.address} No errors, just blank results. Not even an object reference to the $hyperlinks array. When I modify line 4 to % $address in $hyperlinks { Write-Host $._address } I get the following error...but it's unclear if I'm trying to read a null array? or if the value is blank. ForEach-Object : Cannot bind parameter 'Process'. Cannot convert the "in" value of type "System.String" to type "System.Management.Automation.ScriptBlock". At F:\path\HyperLinkScrub.ps1:46 char:2 + % <<<< $address in $hyperlinks { + CategoryInfo : InvalidArgument: (:) [ForEach-Object], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.ForEachObjectCommand What am I missing here? I've verified that the Word doc has hyperlinks, and ultimately, I'm trying to diagnose if my script isn't looking for them properly, or if I'm not outputting them to the console properly.

  • AJAX get data from large HTML page as the large HTML page loads

    - by Ed
    Not entirely sure whether this has a name but basically I have a large HTML page that is generated from results in a db. So viewing the HTML page (which is a report) in a browser directly does not display all contents immediately but displays what it has and additional HTML is added as the results from the DB are retrieved... Is there a way I can make an AJAX request to this HTML page and as opposed to waiting until the whole page (report) is ready, I can start processing the response as the HTML report is loaded? Or is there another way of doing it? Atm I make my AJAX response it just sits there for a minute or two until the HTML page is complete... If context is of any use: The HTML report is generated by a Java servlet and the page making the AJAX call is a JSP page. Unfortunately I can't very easily break the report up because it is generated by BIRT (Eclipse reporting extension). Thanks in advance.

  • Parse an HTTP request Authorization header with Python

    - by Kris Walker
    I need to take a header like this: Authorization: Digest qop="chap", realm="[email protected]", username="Foobear", response="6629fae49393a05397450978507c4ef1", cnonce="5ccc069c403ebaf9f0171e9517f40e41" And parse it into this using Python: {'protocol':'Digest', 'qop':'chap', 'realm':'[email protected]', 'username':'Foobear', 'response':'6629fae49393a05397450978507c4ef1', 'cnonce':'5ccc069c403ebaf9f0171e9517f40e41'} Is there a library to do this, or something I could look at for inspiration? I'm doing this on Google App Engine, and I'm not sure if the Pyparsing library is available, but maybe I could include it with my app if it is the best solution. Currently I'm creating my own MyHeaderParser object and using it with reduce() on the header string. It's working, but very fragile. Brilliant solution by nadia below: import re reg = re.compile('(\w+)[=] ?"?(\w+)"?') s = """Digest realm="stackoverflow.com", username="kixx" """ print str(dict(reg.findall(s)))

  • Is there a difference between long-polling and using Comet

    - by Saif Bechan
    I am implementing a system where I need real-time updates. I have been looking at certain scenarios and among all was Comet. Implementing this I do not see any way this is different from traditional long-polling. In both cases you have to send a request, and then the server send a response back. In the browser you interpret the response and then you start a new request. So why should I use comet if in both cases I need to open and close connections.

  • XML/SOAP attributes for a complextype in kSOAP

It is not clear to me if and how I can parse the attributes (att1, att2 and att3) of the event node. Is it even possible with the current kSOAP implementation? Thanks.

  • Permission denied for cvs server via ssh

    - by NovumCoder
    I cant create a new project by importing a java project via eclipse onto my cvs server via internet. I created a directory as root called /priv/cvs/. Then i called "cvs -d /priv/cvs/ init". I created a user named cvs and a groups called cvs. The repository is owned by cvs and in group cvs. Then i created a user "ben" and his only group is cvs. I "chrooted" the user "ben" accessing only the cvs functionality by not allowing to access the server via ssh with password, only by using a public key which is added in his home directory on the server in file authorized_keys2. the contect of authorized_keys2 is as follows: no-port-forwarding,no-X11-forwarding,command="/usr/bin/cvs server" ssh-rsa [public_key_content] rsa-key Connecting to the server works pretty fine. Eclipse asks for the passphrase for the private key to connect to the server. Authentication works and eclipse is able to run cvs commands. But when importing my project by using Team-Share Project. I get the error: The server reported an error: Permission denied projectname: cvs server: cannot open /priv/cvs/CVSROOT/config: Permission denied projectname: Cannot access /priv/cvs/CVSROOT The access right for the cvs root (/priv/cvs/) is set to 770. Which means that the owner, which is cvs and the group participants of the group cvs are allowed to read and write. Why do i get Permission denied? When i set the folder to 777, which means read/write to ALL, then it works. But i dont want that. I only want cvs users read/write to this folder? Is there something i misunderstood about access rules?

  • Why are ASP.Net MVC2 area controller actions callable without including the area in the url path?

    - by Nathan Ridley
    I've just installed Visual Studio 2010 and have created a new MVC2 project so that I can learn about the changes and updates and have discovered an issue with areas that I'm not sure what to make of. I created a new EMPTY MVC2 project I right clicked the project and, from the context menu, added a new area called "Test" In the new test area, I added a controller called "Data". The code is: public class DataController : Controller { // // GET: /Test/Data/ public ActionResult Index() { Response.Write("Hi"); return new EmptyResult(); } } Now, I compile and call this address: http://localhost/mytest/test/data and get the output: Hi All good. Now I call this: http://localhost/mytest/data and get the same response! I thought routing was supposed to take care of this? Am I overlooking something? Or has the default project setup for MVC2 overlooked something?

  • Is That REST API Really RPC? Roy Fielding Seems to Think So.

    - by Rich Apodaca
    A large amount of what I thought I knew about REST is apparently wrong - and I'm not alone. This question has a long lead-in, but it seems to be necessary because the information is a bit scattered. The actual question comes at the end if you're already familiar with this topic. From the first paragraph of Roy Fielding's REST APIs must be hypertext-driven, it's pretty clear he believes his work is being widely misinterpreted: I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC. There is so much coupling on display that it should be given an X rating. Fielding goes on to list several attributes of a REST API. Some of them seem to go against both common practice and common advice on SO and other forums. For example: A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). ... A REST API must not define fixed resource names or hierarchies (an obvious coupling of client and server). ... A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. ... The idea of "hypertext" plays a central role - much more so than URI structure or what HTTP verbs mean. "Hypertext" is defined in one of the comments: When I [Fielding] say hypertext, I mean the simultaneous presentation of information and controls such that the information becomes the affordance through which the user (or automaton) obtains choices and selects actions. Hypermedia is just an expansion on what text means to include temporal anchors within a media stream; most researchers have dropped the distinction. Hypertext does not need to be HTML on a browser. Machines can follow links when they understand the data format and relationship types. I'm guessing at this point, but the first two points above seem to suggest that API documentation for a Foo resource that looks like the following leads to tight coupling between client and server and has no place in a RESTful system. GET /foos/{id} # read a Foo POST /foos/{id} # create a Foo PUT /foos/{id} # update a Foo Instead, an agent should be forced to discover the URIs for all Foos by, for example, issuing a GET request against /foos. (Those URIs may turn out to follow the pattern above, but that's beside the point.) The response uses a media type that is capable of conveying how to access each item and what can be done with it, giving rise to the third point above. For this reason, API documentation should focus on explaining how to interpret the hypertext contained in the response. Furthermore, every time a URI to a Foo resource is requested, the response contains all of the information needed for an agent to discover how to proceed by, for example, accessing associated and parent resources through their URIs, or by taking action after the creation/deletion of a resource. The key to the entire system is that the response consists of hypertext contained in a media type that itself conveys to the agent options for proceeding. It's not unlike the way a browser works for humans. But this is just my best guess at this particular moment. Fielding posted a follow-up in which he responded to criticism that his discussion was too abstract, lacking in examples, and jargon-rich: Others will try to decipher what I have written in ways that are more direct or applicable to some practical concern of today. I probably won’t, because I am too busy grappling with the next topic, preparing for a conference, writing another standard, traveling to some distant place, or just doing the little things that let me feel I have I earned my paycheck. So, two simple questions for the REST experts out there with a practical mindset: how do you interpret what Fielding is saying and how do you put it into practice when documenting/implementing REST APIs? Edit: this question is an example of how hard it can be to learn something if you don't have a name for what you're talking about. The name in this case is "Hypermedia as the Engine of Application State" (HATEOAS).

  • MVVM Madness: Commands

    - by JP
    I like MVVM. I don't love it, but like it. Most of it makes sense. But, I keep reading articles that encourage you to write a lot of code so that you can write XAML and don't have to write any code in the code-behind. Let me give you an example. Recently I wanted to hookup a command in my ViewModel to a ListView MouseDoubleClickEvent. I wasn't quite sure how to do this. Fortunately, Google has answers for everything. I found the following articles: http://blog.functionalfun.net/2008/09/hooking-up-commands-to-events-in-wpf.html http://joyfulwpf.blogspot.com/2009/05/mvvm-invoking-command-on-attached-event.html http://sachabarber.net/?p=514 http://geekswithblogs.net/HouseOfBilz/archive/2009/08/27/adventures-in-mvvm-ndash-binding-commands-to-any-event.aspx http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/ While the solutions were helpful in my understanding of commands, there were problems. Some of the aforementioned solutions rendered the WPF designer unusable because of a common hack of appending "Internal" after a dependency property; the WPF designer can't find it, but the CLR can. Some of the solutions didn't allow multiple commands to the same control. Some of the solutions didn't allow parameters. After experimenting for a few hours I just decided to do this: private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e) { ListView lv = sender as ListView; MyViewModel vm = this.DataContext as MyViewModel; vm.DoSomethingCommand.Execute(lv.SelectedItem); } So, MVVM purists, please tell me what's wrong with this? I can still Unit test my command. This seems very practical, but seems to violate the guideline of "ZOMG... you have code in your code-behind!!!!" Please share your thoughts. Thanks in advance.

  • HTTP Header - ntCoent-Length

    - by DMcKenna
    I get the following HTTP response headers in a particular response. All looks okay. However I have noticed that the content-length appears twice... Content-Length: 2424 ntCoent-Length: 2424 Is there a particular reason why the content-length is returned a second time as ntCoent-Length? HTTP/1.0 200 OK Date: Wed, 26 May 2010 09:38:19 GMT Server: Apache P3P: CP="NOI DSP COR CURa ADMa TA1a OUR BUS IND UNI COM NAV INT" Accept-Charset: iso-8859-1, unicode-1-1;q=0.8 Expires: Sun, 15 Jul 1990 00:00:00 GMT Pragma: no-cache Cache-Control: no-cache Content-Language: en ntCoent-Length: 2424 Connection: close Content-Type: text/html;charset=iso-8859-1 Content-Length: 2424

  • Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

    - by jdk
    I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)

  • How to prove writing specifications beats code cowboys?

    - by Andrew Grant
    So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!
