  • printf field width : bytes or chars?

    - by leonbloy
    The printf/fprintf/sprintf family supports a width field in its format specifier. I have a doubt for the case of (non-wide) char arrays arguments: Is the width field supposed to mean bytes or characters? What is the (correct-de facto) behaviour if the char array corresponds to (say) a raw UTF-8 string? (I know that normally I should use some wide char type, that's not the point) For example, in char s[] = "ni\xc3\xb1o"; // utf8 encoded "niño" fprintf(f,"%5s",s); Is that function supposed to try to ouput just 5 bytes (plain C chars) (and you take responsability of misalignments or other problems if two bytes results in a textual characters) ? Or is it supposed to try to compute the length of "textual characters" of the array? (decodifying it... according to the current locale?) (in the example, this would amount to find out that the string has 4 unicode chars, so it would add a space for padding).

  • Redirect and parse in realtime stdout of an long running process in vb.net

    - by Richard
    Hello there, This code executes "handbrakecli" (a command line application) and places the output into a string: Dim p As Process = New Process p.StartInfo.FileName = "handbrakecli" p.StartInfo.Arguments = "-i [source] -o [destination]" p.StartInfo.UseShellExecute = False p.StartInfo.RedirectStandardOutput = True p.Start Dim output As String = p.StandardOutput.ReadToEnd p.WaitForExit The problem is that this can take up to 20 minutes to complete during which nothing will be reported back to the user. Once it's completed, they'll see all the output from the application which includes progress details. Not very useful. Therefore I'm trying to find a sample that shows the best way to: Start an external application (hidden) Monitor its output periodically as it displays information about it's progress (so I can extract this and present a nice percentage bar to the user) Determine when the external application has finished (so I can't continue with my own applications execution) Kill the external application if necessary and detect when this has happened (so that if the user hits "cancel", I get take the appropriate steps) Does anyone have any recommended code snippets?

  • Spring - scheduling and pooling runnables of different state (each Runnable instance has different

    - by lisak
    Hi, I can't figure out what to use for scheduling and pooling runnables of different state (each Runnable instance has different state). I could use ScheduledExecutorFactoryBean together with MethodInvokingRunnable to supply arguments. But take a look at the key ScheduledExecutorFactoryBean method, it is designed in a way that all task should start at the beginning. protected void registerTasks(ScheduledExecutorTask[] tasks, ScheduledExecutorService executor) { for (ScheduledExecutorTask task : tasks) { Runnable runnable = getRunnableToSchedule(task); if (task.isOneTimeTask()) { executor.schedule(runnable, task.getDelay(), task.getTimeUnit()); } else { if (task.isFixedRate()) { executor.scheduleAtFixedRate(runnable, task.getDelay(), task.getPeriod(), task.getTimeUnit()); } else { executor.scheduleWithFixedDelay(runnable, task.getDelay(), task.getPeriod(), task.getTimeUnit()); } } } } I can't think of how to setup this scenario with ThreadPoolTaskScheduler. Please help me out here. Thank you EDIT: shortened version is: how to setup task scheduler that would run hundreds of "different instances of Threads (with different state) with 2 seconds interval.

  • Getting HTTP GET variables using Tipfy

    - by Vestonian
    Hey everyone, I'm currently playing around with tipfy on Google's Appengine and just recently ran into a problem: I can't for the life of me find any documentation on how to use GET variables in my application, I've tried sifting through both tipfy and Werkzeug's documentations with no success. I know that I can use request.form.get('variable') to get POST variables and **kwargs in my handlers for URL variables, but that's as much as the documentation will tell me. Any ideas?

  • XPath find element based on ancestor element

    - by martymcfly
    Hi, again I have Java AST which is created from public class Test { String o = new String("hh"); public void wrong1() { synchronized(o) { // huhu } } } I try to create a XPath query which finds the synchronized block in which the defined String variable o is used. As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working //SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]] I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part. Hope its clear what i mean ;-) Thanks

  • How to set up Flex Unit 4

    - by macke
    Does anyone know of any guides or any sort of documentation on how to set up the new Flex Builder 4 beta? I've been pulling my hair all day long, none of my tests are executed and I can't for the life of me understand what's wrong. There are no errors at all. It's as if the metadata tags are not recognized, is there some special compiler argument to recognize them? I seem to remember that this is not necessary as long as the swc files that are included were compiled with said arguments. I'm using Beta 1 of Flex Unit 4 which can be found here: http://opensource.adobe.com/wiki/display/flexunit/FlexUnit+4+feature+overview I'm actually using the very same code that is included with that package to run the tests, but no tests are executed. Neither mine nor the ones included in the FU4 package. The lack of documentation certainly doesn't help much...

  • using the data-custom="" to bind to events

    - by Dean Peterson
    I'm pretty sure I'm gonna get slammed on this. I love using the data-whatever attribute to bind events to. It feels very clean to me and helps reserve my class attribute for just styling. I know this selector is among the slowest, so I don't use it when there are a lot of elements. Would love to hear compelling arguments against this. $("body").delegate("[data-action]", "click", function(){ var action = $(this).attr("data-action"); //route action to appropriate function });

  • What is a python equivalent of PHP's var_dump()

    - by Zoredache
    When debugging in PHP I frequently find it useful to simply stick a var_dump($foo, $bar, ...) in my code to show me the the what a variable is, what is value is, and the same for anything that it contains. What is a good python equivalent for this? I have seen several things in my Google searching that are somewhat equivalent, but nothing that is the same or better.

  • How would you organize this Javascript?

    - by Anurag
    How do you usually organize complex web applications that are extremely rich on the client side. I have created a contrived example to indicate the kind of mess it's easy to get into if things are not managed well for big apps. Feel free to modify/extend this example as you wish - http://jsfiddle.net/NHyLC/1/ The example basically mirrors part of the comment posting on SO, and follows the following rules: Must have 15 characters minimum, after multiple spaces are trimmed out to one. If Add Comment is clicked, but the size is less than 15 after removing multiple spaces, then show a popup with the error. Indicate amount of characters remaining and summarize with color coding. Gray indicates a small comment, brown indicates a medium comment, orange a large comment, and red a comment overflow. One comment can only be submitted every 15 seconds. If comment is submitted too soon, show a popup with appropriate error message. A couple of issues I noticed with this example. This should ideally be a widget or some sort of packaged functionality. Things like a comment per 15 seconds, and minimum 15 character comment belong to some application wide policies rather than being embedded inside each widget. Too many hard-coded values. No code organization. Model, Views, Controllers are all bundled together. Not that MVC is the only approach for organizing rich client side web applications, but there is none in this example. How would you go about cleaning this up? Applying a little MVC/MVP along the way? Here's some of the relevant functions, but it will make more sense if you saw the entire code on jsfiddle: /** * Handle comment change. * Update character count. * Indicate progress */ function handleCommentUpdate(comment) { var status = $('.comment-status'); status.text(getStatusText(comment)); status.removeClass('mild spicy hot sizzling'); status.addClass(getStatusClass(comment)); } /** * Is the comment valid for submission */ function commentSubmittable(comment) { var notTooSoon = !isTooSoon(); var notEmpty = !isEmpty(comment); var hasEnoughCharacters = !isTooShort(comment); return notTooSoon && notEmpty && hasEnoughCharacters; } // submit comment $('.add-comment').click(function() { var comment = $('.comment-box').val(); // submit comment, fake ajax call if(commentSubmittable(comment)) { .. } // show a popup if comment is mostly spaces if(isTooShort(comment)) { if(comment.length < 15) { // blink status message } else { popup("Comment must be at least 15 characters in length."); } } // show a popup is comment submitted too soon else if(isTooSoon()) { popup("Only 1 comment allowed per 15 seconds."); } });

  • Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

    - by Louise
    I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

  • php POST and non-english language chars passes empty

    - by haim evgi
    I'm trying to program a Hebrew site with a search option. (old site and the charset of this site is windows-1255) I am using php 5.2 with Apache 2.2, on a Debian 5 (Lenny) with appropriate code pages enabled. I am using _POST to pass arguments to a script. If I pass English word to the script everything works, but when I use Hebrew nothing is passed through the POST function. When I use ECHO to show _POST, the variable is empty. What might be the problem? P.S. this is old site that worked fine on PHP 4 with debian 4, and the problem arised only after we upgrade to PHP5+debian5.

  • C# Spell checker Problem

Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.
