  • Java Implementing htonl

    - by Hamza Yerlikaya
    I am communicating with a server, each message sent to the server has to be padded with the length of the message, unsigned int len = htonl(msg.size()); In C running the length through htonl and padding the message works, in Java AFAIK byte order is already in network order so I assumed all I have to do is write the string length before the message to the stream, but this does not work am I missing something? stream.write(msg.length()); stream.write(msg.getBytes()); Stream is an OutputStream.

  • Cannot use Html.ActionLink in asp.net mvc spark files

    - by midas06
    I'm using the spark view engine with my asp.net mvc application. In my aspx pages, I can succesfully use Html.Actionlink, but when I attempt it in spark files, it doesnt show up in intellisense, and when i try to run it anyway, i get: Dynamic view compilation failed. c:\Users\midas\Documents\Visual Studio 2008\Projects\ChurchMVC\ChurchMVC\Views\Home\Index.spark(73,25): error CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'ActionLink' and no extension method 'ActionLink' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?) I do have system.web.mvc referenced, and I have added in _global.spark. None of that helps. Any ideas?

  • Why is LOGON_USER Server Variable is blank on New Windows / New Tab?

    - by Alex Papadimoulis
    We are noticing some very strange behavior on an installation of a .NET2-based webapp on Server 2008. Our app uses "old school" Integrated Windows Authentication and simply reads the LOGIN_USER server variable from the request collection. There's a good reason for this, but that's somewhat irrelevant to the question, since the underlying WindowsAuthentication code from ASP.NET does the same thing. Anyway... When you enter the URL in the browser, it loads up just fine and displays the username (from LOGIN_USER) no problem. When you click on a link within the web app, it loads the page just fine and authenticates without any problems. When you "hard refresh" (Ctrl-F5) it also works just fine. However, when you click "open in a new window" or "open in a new tab", the LOGON_USER variable is blank Any ideas? Am I missing some IIS7 setting somewhere? Tested clients are Windows 7 with IE8 or Windows XP with IE6.

  • How to gracefully exit SLIME and EMACS

    - by Gregory Gelfond
    Hi All, I have a question regarding how to "gracefully exit SLIME", when I quit Emacs. Here is the relevant portion of my config file: ;; SLIME configuration (setq inferior-lisp-program "/usr/local/bin/sbcl") (add-to-list 'load-path "~/Scripts/slime/") (require 'slime) (slime-setup) ;; configure SLIME to gracefully quit when emacs ;; terminates (defun slime-smart-quit () (interactive) (when (slime-connected-p) (if (equal (slime-machine-instance) "Gregory-Gelfonds-MacBook-Pro.local") (slime-quit-lisp) (slime-disconnect))) (slime-kill-all-buffers)) (add-hook 'kill-emacs-hook 'slime-smart-quit) To my knowledge this should automatically kill SLIME and it's associated processes whenever I exit Emacs. However, every time I exit, I still get the prompt: Proc Status Buffer Command ---- ------ ------ ------- SLIME Lisp open *cl-connection* (network stream connection to 127.0.0.1) inferior-lisp run *inferior-lisp* /usr/local/bin/sbcl Active processes exist; kill them and exit anyway? (yes or no) Can someone shed some insight as to what I'm missing from my config? Thanks in advance.

  • What is purpuse of T4 Generator in T4toolbox

    - by Fred Yang
    I am using T4toolbox, I am confused what the generator is for. I can run the following public class Generator1 : Generator { protected override void RunCore() { Template1 t = new Template1(); t.Output.File = "t3.txt"; t.Render(); } } or I can run t4 script directly like the following. Template1 t = new Template1(); t.Output.File = "t3.txt"; t.Render(); But I can do the same using t4 script without generator as well. So I mean can do the same thing with two approach "script -- generator -- template" and "script -- template", am I missing something? Thanks

  • Why doesn’t ABPersonViewController show any properties besides the name?

    - by abrahamvegh
    For some reason, ABPersonViewController is unwilling to display any properties aside from the name, no matter what properties are set for it to display. I’m unable to use the AddressBookUI controllers to let a user select a contact to display, since my UI has custom requirements, otherwise I’d go that route (as Apple does in their sample project.) Here’s the code that doesn’t work — am I missing something? - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // ABContact is of my own creation ABContact *contact = [self contactAtIndexPath: indexPath]; ABPersonViewController *viewController = [[ABPersonViewController alloc] init]; // This returns a valid ABRecordRef, as indicated by the fact that the // controller does display the name of this contact when it is loaded viewController.displayedPerson = contact.record; // Copied directly from Apple’s QuickContacts sample project NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty], [NSNumber numberWithInt:kABPersonEmailProperty], [NSNumber numberWithInt:kABPersonBirthdayProperty], nil]; viewController.displayedProperties = displayedItems; [self.navigationController pushViewController: viewController animated: YES]; [viewController release]; }

  • com.sun.management.OperatingSystemMXBean use in an OSGi bundle

    - by Paul Whelan
    I have some legacy code that was used to monitor my applications cpu,memory etc that I want to convert to a bundle. Now when i start this bundle its complaining Missing Constraint: Import-Package: com.sun.management; version="0.0.0" I had used the OperatingSystemMXBean to get access to stats on the JVM. My question is can I use this class inside an OSGI container and if so how? Or should I use some other way to monitor my application. I was making an RMI call to the application from a web frontend to get the nodes performance figures pre OSGi.

  • processing: convert int to byte

    - by inspectorG4dget
    Hello SO, I'm trying to convert an int into a byte in Processing 1.0.9. This is the snippet of code that I have been working with: byte xByte = byte(mouseX); byte yByte = byte(mouseY); byte setFirst = byte(128); byte resetFirst = byte(127); xByte = xByte | setFirst; yByte = yByte >> 1; port.write(xByte); port.write(yByte); According to the Processing API, this should work, but I keep getting an error at xByte = xByte | setFirst; that says: cannot convert from int to byte I have tried converting 128 and 127 to they respective hex values (0x80 and 0x7F), but that didn't work either. I have tried everything mentioned in the API as well as some other blogs, but I feel like I'm missing something very trivial. I would appreciate any help. Thank you.

  • PHP regex to match sentences that contain a year

    - by zen
    I need a regular expression that will extract sentences from text that contain a year in them. Example text: Next, in 1988 the Bradys were back again for a holiday celebration, "A Very Brady Christmas". Susan Olsen (Cindy) would be missing from this reunion, Jennifer Runyon took her place. This was a two hour movie in which the Bradys got together to celebrate Christmas, introducing the world to the spouses and children of the Brady kids. This movie was the highest rated TV-movie of 1988. If the example text was variable $string, I need it to return: $sentenceWithYear[0] = Next, in 1988 the Bradys were back again for a holiday celebration, "A Very Brady Christmas". $sentenceWithYear[1] = This movie was the highest rated TV-movie of 1988. If it's possible to retain the year via regex, I'd use the year within the sentence and eventually insert the sentences into a database like: INSERT INTO table_name (year, sentence) VALUES ('$year', '$sentenceWithYear[x]')

  • How do you run PartCover with spaces in the path?

    - by nportelli
    I have a msbuild file that I'm trying to run from Hudson CI. It outputs like this "C:\Program Files\Gubka Bob\PartCover .NET 2\PartCover.exe" --target "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\MSTest.exe" --target-args "/noisolation" "/testcontainer:C:\CI\Hudson\jobs\Video Raffle\workspace\Source\VideoRaffleCaller\Source\VideoRaffleCaller.Test.Unit\bin\Debug\VideoRaffleCaller.Test.Unit.dll" --include "[VideoRaffleCaller*]*" --output "Coverage\partcover.xml" I get this error Invalid switch "raffle\workspace\source\videorafflecaller\source\videorafflecall er.test.unit\bin\debug\videorafflecaller.test.unit.dll". For switch syntax, type "MSTest /help" WTF? Looks like PartCover doesn't handle spaces in the --target-args well. Or am I missing some quotes somewhere? Has anyone gotten something like to to work?

  • Wireframe mock-up software

    - by Dave Jarvis
    Requirements Looking for wireframe mock-up software for web apps with the following constraints: Desktop application (supports Linux) (can be online) Export all pages to separate image files (PNG or SVG preferred) Template for all pages Drag and drop standard HTML widgets for <forms> Tabbed panels (that allow content on the different tabs) Shuttle controls Saves in an XML format (XSLT could convert to HTML) Widget alignment and resizing (relative to other widgets) Under $100.00 USD Examples That come close: Cacoo - Not a desktop application; does not have a true tabbed panel widget Pencil - Export feature has serious bugs (missing text); no template? Balsamiq - Installation proved cantankerous on Linux (due to Adobe AIR) Mockingbird - No shuttle controls; no auto-resize of widgets Pencil & paper - Not a good look for a formal document presented to clients Any others that meet the requirements?

  • Facebook Connect - logout issue

    - by Gublooo
    Hello I think I'm missing a very silly detail but the logout funtion of facebook connect is not working for me. I followed the steps posted in this answer by Typeoneerror but I cant get it to work. This is my logout javascript function function logout() { FB.init("API_KEY", "/xd_receiver.htm"); FB.Connect.logoutAndRedirect("/logout/url"); } When I click on it - nothing happens - In the browser status bar - For a second I see a message which says waiting for facebook - but I continue to stay on the same page. It does not redirect me nor does it log me out of facebook either. Just to see if the function is being called - I removed FB.init call from the function and then I get the error Error Message: 'FB.Connect' is null or not an object Any suggestions on how to debug this. Thanks a lot

  • Saving a select count(*) value to an integer (SQL Server)

    - by larryq
    Hi everyone, I'm having some trouble with this statement, owing no doubt to my ignorance of what is returned from this select statement: declare @myInt as INT set @myInt = (select COUNT(*) from myTable as count) if(@myInt <> 0) begin print 'there's something in the table' end There are records in myTable, but when I run the code above the print statement is never run. Further checks show that myInt is in fact zero after the assignment above. I'm sure I'm missing something, but I assumed that a select count would return a scalar that I could use above?

  • Integrate Jasper in Rails 3

    - by AndreDurao
    I'm trying to integrate a rails 3 app with jasper following this wiki: http://wiki.rubyonrails.org/rails/pages/HowtoIntegrateJasperReports But it seems that a lot of information isn't updated so it's been very hard to make it work by myself. I've also read a topic at ruby-forum: http://www.ruby-forum.com/topic/139453 with some details explained but still couldn't make it work. My first problem is related with the render_to_string method: When the controller method runs I receive a "Template is missing" error: this is the method: def report @customers = Customer.all send_doc(render_to_string(:template => report_customers_path, :layout => false), '/pdfs', 'report.jasper', "customers", 'pdf') end Although this seems simple I'm not understanding why is this happening. Doesn't render_to_string with layout = false suposed to get me the string result of that action? I also tried :action instead of :template, but it does the same. If anybody with some expertise with this integration could help... Thanks in advance, André

  • How to learn high-level Java web development concepts

    - by titaniumdecoy
    I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

  • Testing across multiple sessions in merb using webrat

    - by m7d
    I want to test across multiple sessions using webrat in merb. Apparently, this is fairly easy to accomodate in Rails via: http://erikonrails.snowedin.net/?p=159. Following the same logic, I am trying to do something that follows that pattern for merb and webrat. Here is an attempt (which does not work because MerbAdapter does not respond to visit and other webrat session methods; I don't want to take too much more time with this so I have stopped here for now): # defined in test.rb environment file module Merb #:nodoc: module Test #:nodoc: module RequestHelper #:nodoc: def in_a_separate_session old = @_webrat_session.response.clone @_webrat_session = Webrat::MerbAdapter.new yield @_webrat_session.response = old end end end end I tried a few other ideas, but obviously I am missing something. Anyone else know how this would be done in merb? I think I could specify a cookie jar using the request mock, but I prefer to do this with webrat.

  • Python decoding issue with hashlib.digest() method

    - by Sorw
    Hello StackOverflow community, Using Google App Engine, I wrote a keyToSha256() method within a model class (extending db.Model) : class Car(db.Model): def keyToSha256(self): keyhash = hashlib.sha256(str(self.key())).digest() return keyhash When displaying the output (ultimately within a Django template), I get garbled text, for example : ?????_??!`?I?!?;?QeqN??Al?'2 I was expecting something more in line with this : 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 Am I missing something important ? Despite reading several guides on ASCII, Unicode, utf-8 and the like, I think I'm still far from mastering the secrets of string encoding/decoding. After browsing StackOverflow and searching for insights via Google, I figured out I should ask the question here. Any idea ? Thanks !

  • nginx + passenger not using rackup file

    - by Callum Jones
    I have an issue where Passenger is not detecting the config.ru file for the following nginx server server { listen 80; passenger_enabled on; server_name callumj.com cjlondon.com; access_log logs/callumj.access.log; root /webapps/callumj_com/public; } Nginx just seems to ignore it and treat it as a normal web page (as I get forbidden areas when it tries to look for index.html in public). I have verified that the rackup command and execute config.ru and it boots up sucessfully. I have another server directive much like this which is powered by Rails and it seems to be working perfectly. Am I missing something? Thanks in advance!

  • How do I start a second console application in Visual Studio when one is already running

    - by Kettenbach
    Hi All, I am working through some examples in a WCF book. There is a Host project and Client project within a single solution. Both are console applications. The Host is the startup app, but the Client app doesn't seem to open the Console like the book says. Book says while the Host is running, run the Client. The Run button is disabled tho as it is already running. The book example definitely has them in the same solution and a single instance of Visual Studio. Anyways, what am I missing here? I have done this with two instances of VS, but I truly have never does this in a single instance. Any help is always appreciated. Cheers, ~ck in San Diego

  • How to make my iPhone app compatible with iOS 4?

    - by Davide
    Hello, My iphoneos 3.1 based application is not working on iOS 4 GM: the camera is not showing in full screen, it doesn't correctly detects compass information, the uiwebviews doesn't respond to touches (they don't scroll), and so on. It's completely broken! Now my question is: how can I develop an update using the latest xcode with support for ios 4? The latest iOS 4 xcode (3.2.3) doesn't provide any way to develop for iPhoneOS 3.x ("base sdk missing"). By the other side, xcode 3.2.2 would not allow me to debug it on a iOS 4 device, so I can't test it.
