• Align text with right edge of an html form

  - by williamjones

  I have an html form where the width of a textarea is specified with cols=. I want the textarea to have a specific width in terms of number of characters. However, I also want some controls to be right-justified to the right edge of the textarea. They're not in the textarea, but directly above or below it. Is it possible to do this? I was thinking a possible approach might be enclosing the textarea with some type of container that could grow to the width of the textarea, but I'm not sure how I could right-justify text within that.

• Handling download abort in PHP

  - by Aron Rotteveel

  Is it somehow possible to handle a download abort in PHP? In this specific case I am not speaking of a connection abort, but handling the event that triggers when the 'cancel' button in the browser download dialog button is clicked. Since this dialog already interprets the headers of the file that is to be download but does not actually start the download, it only seems logical there should be some way to catch this. Small (pseudo) code example to clear things up: // set some headers header('...'); // Question: what happens between the part where the headers are sent // and the actual data is being outputted to the client? IE: this is the part // where the download dialog should show up // Logical question that follows is: is there a way to detect a 'cancel'? $filename = '/some/file.txt'; $handle = fopen($filename, 'rb'); // output data to client while (!feof($handle)) { echo fread($handle, 8096); } fclose($handle);

• How do I synchronize GUI-Elements?

  - by anonymous2500

  Hello, I have a little problem with my java-program. I wanna use Observer, to synchronize two GUIs. But I can't synchronize the JComponent / JButton elements. For example: I have a GUI-Class which implements the Observer-Class: public class GUI extends JFrame implements Observer I have a second "GUI"-Class which extends the JButton-Class and makes changes on a specific Button-Element. public class Karte extends JButton{ ... this.setEnabled(false); ... How do I synchronize this Button via Observable? I have already tried to use "extends Observable" in this class, but the "setEnabled()" method is explicit for the JButton-Class, which is not Observable! Can someone help? Thanks.

• Does Google appengine cache external requests?

  - by Andy Hume

  I have a very simple application running on appengine that requests a web page every five minutes and parses for a specific piece of data. Everything works fine except that the response I get back from the external request (using urllib2) doesn't reflect the latest changes to the page. Sometimes it takes a few minutes to get the latest, sometimes over an hour. Is there a transparent layer of caching that appengine puts in place? Or is there something else I am missing here? I've looked at the caching headers of the requested page and there is no Expires or LastModified's sent. Update: Sometimes, it will get the new version of the page for a number of requests and then randomly later get an old out of date version.

• position:fixed on element in ie7/8 and problems with the scrolling of the content inside it

  - by jayarjo

  I got an element fixed in the center of the screen, having specific dimensions (let's say 500x500). The element has content, which is larger then the height of the element and thus causes scroll bar to appear, which is fine. In FF/WebKit everything works nice. However in IE 7/8 ... content of the fixed element doesn't scroll, or scrolls with HUGE delay. If I change position:fixed to position:absolute, it starts to scroll fine, but with position:fixed... it's just a pain!.. Is it some known issue? Anyone heard/encountered something like that? Any ideas how to deal with such?...

• File synck tool with network support (FTP or SSH) and decent GUI

  - by Álvaro G. Vicario

  Is there a decent GUI tool for Windows that allows to publish files from/to a remote FTP (or SFTP) server with the same ease of use that WinMerge offers in local discs? I'll basically use it to upload changes to web sites. I've tried like a dozen tools and they're all terrible. They have difficult interfaces, you need to spend ten minutes configuring absurdly complicate project settings, there's no simple way to ignore specific files or they use custom databases that break when someone else uploads files—not to mention deployment frameworks that force you to script everything in their custom language. I don't need or even want to schedule or automate. I want a manual process I can review. I'm tired of picking files one by one in Filezilla while reading the Subversion logs. I'd love an open source tool but...

• How can I measure file access performance (and volume) of a (Java) application

  - by stmoebius

  Given an application, how can I measure the amount of data read and written by that application? the time spent reading/writing to disk? The specific application is Java-based (JBoss), and multi-threaded, and running as a service on Windows 7/2008 x64. The overall goal I have is determining whether and why file access is a bottleneck in my application. Therefore, running the application in a defined and repeatable scenario is a given. File access may be local as well as on network shares. Windows performance monitor appears to be too hard to use (unless someone can point me to a helpful explanation). Any ideas?

• Custom Control Overriding Command Button

  - by pm_2

  I am trying to create a custom command button that defaults width and height to specific settings. I have the following code: public partial class myCommandButton : Button { public magCommandButton() { InitializeComponent(); } [DefaultValue(840)] public override int Width { get { return base.Width; } set { base.Width = value; } } [DefaultValue(340)] public override int Height { get { return base.Height; } set { base.Height = value; } } protected override void OnPaint(PaintEventArgs pe) { base.OnPaint(pe); } } However, it won't compile because it tells me that I can not override Width or Height. Can anyone tell me if I'm approaching this wrongly, or if there's a way around this?

• Best way to store application images taken via camera

  - by Dave

  Hi all, I'm just looking for some insight into what would be the best way for me to store images as part of my app. I have an activity that represents a 'Job' which has a couple of edittext's and underneath was planning on using the Gallery component to show images relevant to this job. The job data is stored in a database (on the sdcard) so was also thinking of creating a table to store 'JobImages' and having each image stored as a byte array. But I'm not sure if it would be better to store the images directly on sdcard under a folder structure specific to my application and the job. E.g. using the job ID number as a folder name. Depending on which method I use will greatly determine the code that goes into an 'adapter' that allows me to bind to the gallery component so before I begin I was wondering if anyone has had the same design problem and what option they chose. Thanks, Dave

• Fully automated MS SQL Restore

  - by hasen j

  I'm not very fluent with MS-SQL commands. I need a script to restore a database from a .bak file and move the logical_data and logical_log files to a specific path. I can do: restore filelistonly from disk='D:\backups\my_backup.bak' This will give me a result set with a column LogicalName, next I need to use the logical names from the result set in the restore command: restore database my_db_name from disk='d:\backups\my_backups.bak' with file=1, move 'logical_data_file' to 'd:\data\mydb.mdf', move 'logical_log_file' to 'd:\data\mylog.ldf' How do I capture the logical names from the first result set into variables that can be supplied to the "move" command? I think the solution might be trivial, but I'm pretty new to mssql.

• facebook api getting full posts with > 2 comments or > 4 likes

  - by ejang

  when I make the user/feed request on the Facebook Open Graph API, I get a feed object where posts with 2 comments or 4 likes don't reveal the detailed information for those specific comments. I am using https://github.com/Thuzi/facebook-node-sdk to make requests but it is very similar to the 'request' NodeJS library. I can get the full posts individually by making a separate request for that post's Open Graph ID, but this doesn't lend itself to fun code because requests are asynchronous and nesting more asynchronous calls within asynchronous calls doesn't lend itself to fun code. Any way I can obtain the full posts?

• Prevent Users from Performing an Action Twice

  - by TheOnly92

  We have some problems with users performing a specific action twice, we have a mechanism to ensure that users can't do it but somehow it still happens. Here is how our current mechanism works: Client side: The button will be disabled after 1 click. Server side: We have a key hash in the URL which will be checked against the key stored in SESSIONS, once it matches, the key is deleted. Database side: Once the action is performed, there is a field to be flagged indicating the user has completed the action. However, with all these measures, still there are users able to perform the action twice, are there any more safer methods?

• how to print number with commas as thousands separators in Javascript

  - by mikez302

  I am trying to print an integer in Javascript with commas as thousands separators. For example, I want to show the number 1234567 as "1,234,567". How would I go about doing this? Here is how I am doing it: function numberWithCommas(x) { x = x.toString(); var pattern = /(-?\d+)(\d{3})/; while (pattern.test(x)) x = x.replace(pattern, "$1,$2"); return x; } I am wondering if anyone has a simpler or more elegant idea. It would be nice if it works with floats also, but that is not necessary. It does not need to be locale-specific to decide between periods and commas.

• Is there a c++ library that provides functionality to execute an external program and read its outpu

  - by BD at Rivenhill

  Basically, I'm looking for something that will allow me to replicate the following Perl code: my $fh = new FileHandle; $fh->open("foo |"); while (<$fh>) { # Do something with this line of data. } This is in the context of Linux, so a library that is specific to Windows will not help. I know how to write a program that does fork/exec/dup2 and all that basic shell-type jazz, but there are some fiddly details involving terminals that I don't feel like messing around with (and I don't have a copy of "Advanced Programming in the UNIX Environment" or a similar reference handy), so I'm hoping that someone has already solved this problem.

• PHP no wait sem_acquire?

  - by SerEnder

  Not a specific code question, but more of a general coding question. I'm trying to use a semaphore in a work project to limit the number of users that can access certain processes at a concurrent time. From my understanding the following: $iKey = ftock($sSomeFileLocation,'sOneCharacterString'); //Generate the key if($sem_id = sem_get($iKey){ //1 user allowed if(sem_acquire($sem_id)){ //Do the limited process here sem_release($sem_id); } } The problem that I see here is that if there is already one user who has the semaphore key, then the next user just waits until the first user is done rather than just faulting out. Anyone know of a way that if the max_acquire number has been reached, sem_acquire (or similar) will just return false? Thanks

• Why does this jQuery dropdown menu display subcategory selections only for certain top-level categories?

  - by chunkymonkey

  I'm trying to implement a dropdown menu based on a jQuery plugin from Filament Group: http://jsfiddle.net/chunkymonkey/Pr8k4/ What I am having difficulty fixing is a bug where certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has equally many subcategories, shows no subcategories when expanded. I would be very grateful if anyone could help me figure out what's causing this. Thanks. UPDATE: Just noticed this problem may be Chrome-specific(??). I just tested it in IE8 and Firefox and it seems to work correctly in both.

• Why are most really fast servers written in C instead of C++?

  - by orokusaki

  I'm trying to decide which to learn and I've read all the "Which is better" questions/arguments, so I thought I'd get your take on something more specific. Is there a platform dependency issue that C++ developers run into with such applications? Or, is it because there are more C developers out there than C++? I also noticed that many more third party C modules exist for Python even thought C++ modules are supported. From what I've read on different threads the consensus is that C++ is easier and faster to write, and runs just as fast. Am I missing something really big. Examples: NGINX APE (comet server) Apache

• Documented process for using facebook connect for the iPhone to upload photos

  - by Corey Floyd

  After looking I did come accross this post on the facebook forums: link They are feeding the facebook object a UIImage. That seems logical, but where is this documented? The API documentation is generalized to all platforms. Where are the iPhone specific requirements for arguments and their data types? Thanks **Update***** I still have not came across any API docs pertaining to Cocoa. I did, however, gather the information I needed by piecing together forum information, Facebook sample code, and some glue. Hopefully they'll issue something a little more concrete over the next few months.

• WPF: Creating instances of resources?

  - by oakskc

  I'm brand spanking new to WPF and am trying to play around with projects to better understand what I'm reading. My understanding of a resource is that it is the instance, you can't use it like a factory and create instances of it. For example, a XAML-defined rectangle. You can reference it, but you can't have numerous instances of it all over the surface. In WPF, what would be the way to do that? If I define a Rectangle as a resource with specific properties and wanted to have multiple instances of that within a dynamically-generated grid, how should I be going about it? Or is there a different way I should be trying to do this? Purely academic exercise with no real-world application.

• Interview Programming Questions - In house Exam

  - by David McGraw

  I have a company that would like to bring me in to serve me an hour long exam. No resources other than a pencil and paper. I really couldn't get any sort of feedback on the type of exam (implementation or generic) beside that it would test a few specific areas. Have you done anything like this? What sort of questions did they ask? What's a good way to prepare? I'll probably go in a couple weeks before school starts back up. A time sensitive exam structure is a weak point for me, so what should I absolutely focus down on? If they like the exam, that's when I'll get a face-to-face meeting. An advance thanks goes to everybody who provide their time.

• Connection: Keep-Alive and PHP sessions not working

  - by user366667

  We have a VB application that needs to run an specific flow on a PHP page. This application was correctly catching the PHPSESSID cookie and using it for all subsequent requests. However, PHP wasn't able to restore any changes made on $_SESSION variable. The variable was changed, saved, and on the next request it was restored as an empty array. We found out that changing the Connection header from "Keep-Alive" to "Close" fixed the issue. I couldn't find anything on the web saying that PHP sessions shouldn't be restored under Keep-Alive connections. Does anyone know why this was happening? PS: We didn't find anything weird or different on Apache, ModSecurity or PHP configuration settings.

• Select one column from a row in hibernate

  - by ComfortablyNumb

  I am trying to do a simple query to get a unique result back in hibernate here is my code. public String getName(Integer id) { Session session = getSessionFactory().openSession(); String name = (String)session.createSQLQuery("SELECT name FROM users WHERE user_id = :userId").setParameter("userId", id).uniqueResult(); return name; } The name that is being returned is stored as HTML text that includes html syntacx language. I think this is what is causing the problem but it doesnt make sense I just want to return it as a string. It is only happening on this one field name, I can get every other field in the row but this one it gives me the error. I am getting an exception. The exception I am getting is No Dialect mapping for JDBC type: -1; nested exception is org.hibernate.HibernateException How do you query for a specific column on a row in hibernate?

• Convert PHP array into Key => Value Array

  - by Feature

  Total PHP Noob and I couldn't find an answer to this specific problem. Hope someone can help! $myvar is an array that looks like this: Array ( [aid] = Array ( [0] = 2 [1] = 1 ) [oid] = Array( [0] = 2 [1] = 1 ) ) And I need to set a new variable (called $attributes) to something that looks like this: $attributes = array($myvar['aid'][0] => $myvar['oid'][0], $myvar['aid'][1] => $myvar['oid'][1], etc...); And, of course, $myvar may contain many more items... How do I iterate through $myvar and build the $attributes variable?

• In Java how instance of and type cast(i.e (ClassName)) works on proxy object ?

  - by learner

  Java generates a proxy class for a given interface and provides the instance of the proxy class. But when we type cast the proxy object to our specific Object, how java handles this internally? Is this treated as special scenario? For example I have class 'OriginalClass' and it implements 'OriginalInterface', when I create proxy object by passing 'OriginalInterface' interface java created proxy class 'ProxyClass' using methods in the provided interface and provides object of this class(i.e ProxyClass). If my understanding is correct then can you please answer following queries 1) When I type cast object of ProxyClass to my class OriginalClass this works, but how java is allowing this? Same in case of instace of? 2) As my knowledge java creates a proxy class only with the methods, but what happen when I try to access attributes on this object? 3) Only interface methods are getting implemented in Proxy, but what happens when I try to access a method which not in interface and only mentioned in the class? Thanks, Student
