• Check through Javascript that page is loading something

  - by Lilitu88

  When the browser is loading something on a page you can see it in the status bar that it says "Waiting for..." or "Transfering..." etc. In firebug you can check in the net tab when something is being loaded and see when it stops. That is what I want. Is there a way for me to trigger an event when that happens ? Or to get the status of the page or something ? Any way for me to know when that changes ? I know I can do this easier if I use Ajax, but I can't since the page it's expecting an Excel report. Thanks

• Security when writing a PHP webservice?

  - by chustar

  I am writing a web service in PHP for the first time and had ran into some security problems. 1) I am planning to hash passwords using md5() before I write them to the database (or to authenticate the user) but I realize that to do that, I would have to transmit the password in plaintext to the server and hash it there. Because of this I thought of md5()ing it with javascript client side and then rehashing on the server but then if javascript is disabled, then the user can't login, right? 2) I have heard that anything that when the action is readonly, you should use GET but if it modifies the database, you should use POST. Isn't post just as transparent as GET, just not in the address bar?

• 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?...

• Where can I find "reference barcodes" to verify barcode library output?

  - by mjustin

  This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

• Swing: set JFrame content area size

  - by igul222

  I'm trying to make a JFrame with a usable content area of exactly 500x500. If I do this... public MyFrame() { super("Hello, world!"); setSize(500,500); } ... I get a window whose full size is 500x500, including the title bar, etc., where I really need a window whose size is something like 504x520 to account for the window border and titlebar. How can I achieve this?

• Storing Object Types in Variable then Initializing

  - by Jon Mattingly

  Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

• HTTP Download very Big File

  - by Luca

  I'm working at a web application in Python/Twisted. I want the user to be able to download a very big file ( 100 Mb). I don't want to load all the file in memory (of the server), of course. server side I have this idea: ... request.setHeader('Content-Type', 'text/plain') fp = open(fileName, 'rb') try: r = None while r != '': r = fp.read(1024) request.write(r) finally: fp.close() request.finish() I expected this to work, but I have problems: I'm testing with FF... It seems the browser make me wait until the file is completed downloaded, and then I have the open/save dialog box. I expected the dialog box immediately, and then the progress bar in action... Maybe I have to add something in the Http header... Something like the size of the file?

• Visual Studio 2010 Macro - Reporting Progress

  - by user295841

  I have just discovered macros in Visual Studio and I can't be happier. Well... I have my complaints but... you know ;) A few of my macros are taking quite a while to complete and I am looking for a way to track progress. I build a log file during most of my macro processes but I have not found a good way to report progress without pausing the process. Ex. MsgBox("Progress") Any way to access the output window or even better the VS status bar?

• PHP imap_search not detecting all messages in gmail inbox

  - by Steve

  When I run a very simple imap_search on my GMail inbox, the search returns less messages than it should. Here is the script that anyone with a GMail account can run. $host = '{imap.gmail.com:993/imap/ssl}'; $user = 'foo'; $pass = 'bar'; $imapStream = imap_open($host,$user,$pass) or die(imap_last_error()); $messages = imap_search($imapStream,"ALL"); echo count($messages); imap_close($imapStream); This returns 39 messages. But, I've got 100 messages in my inbox, some in conversations, some forwarded from another account (SquirrelMail, FWIW). Can anyone duplicate these results, and/or tell me what's going on? Other server strings I've tried, all returning the same results: {imap.gmail.com:993/imap/ssl/novalidate-cert} {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX {imap.gmail.com:993/imap/ssl}INBOX GMail's IMAP feature support: http://mail.google.com/support/bin/answer.py?hl=en&answer=78761

• How to disable Eclipse's behavior of maximizing editor when double clicking a tab?

  - by Steve Kehlet

  I recently updated my Eclipse (now running 20100218-1602), and I've found whenever I click around quickly between tabs on the tab bar, it will sometimes maximize the editor and hide the PHP Explorer to the left. After researching a little, this appears to be a feature of double clicking a tab. So I guess it's my fault, I'm sure I'm clicking around too fast and mistakenly double clicking a tab, but it happens often enough on what I'd consider a normal editing session that I've come to absolutely loathe it, and even after the usual googling due diligence cannot figure out how to turn it off. From this post (http://stackoverflow.com/questions/594659/eclipses-tab-double-click-on-visual-studio) someone mentions the Window.AutoHideAll shortcut, however that seems to only be for assigning keyboard shortcuts--this is a mouse click thing. But maybe it's a clue. I can't find anything relevant under Eclipse - Preferences - PHP. I don't think it's specific to PHP because if I switch to the Java perspective, double clicking a tab hides the Package Explorer. Any suggestions are appreciated, thanks!

• Remove .php extension (explicitly written) for friendly URL

  - by miquel

  htaccess to remove the .php extension of my site's files. RewriteEngine on RewriteBase / RewriteCond %{SCRIPT_FILENAME} !-d RewriteCond %{SCRIPT_FILENAME} !-f RewriteRule ^(.*)$ $1.php [L,QSA] Now, if I go to my site www.mysite.com/home works fine, it redirects to home.php but the URL is still friendly.

• Data driven charts and graphs from xml to svg

  - by garymlewis

  I asked this question a week ago, but did not do a good job of describing the problem. Here's a second attempt. I'd like to produce data-driven charts, graphs, and other data visualizations, starting with data in an xml database and ending up with the visualizations as SVG. Here's an example from the W3C. It uses Javascript to create a stacked bar chart as SVG from xml. I'd like to do something similar but use a graphics library (or ???) instead of js to handle the construction of axes, labels, titles, data points, etc. My question, then: what are the options that I should consider ... things like Raphael I suppose, but initially I'd like to cast a wide net and look at many different options. My experience is all with static data visualizations using statistics packages like R, but eventually I'd like to create interactive data visualizations with html5/css3/svg. Any help would be much appreciated. Thanks.

• switch statement with returns -- code correctness

  - by houbysoft

  Hi, let's say I have code in C with approximately this structure: switch (something) { case 0: return "blah"; break; case 1: case 4: return "foo"; break; case 2: case 3: return "bar"; break; default: return "foobar"; break; } Now obviously, the "break"s are not necessary for the code to run correctly, but it sort of looks like bad practice if I don't put them there to me. What do you think? Is it fine to remove them? Or would you keep them for increased "correctness"?

• Google Chrome "window.open" workaround?

  - by McBonio

  Hi Folks! I have been working on a web app and for part of it I need to open a new window. I have this working on all browsers, my sticking point is with Google Chrome. Chrome seems to ignore the window features which is causing me issues, the thing I'm struggling with is I need the address bar to be editable within the new window. FF, IE, Safari and Opera do this fine, Chrome does not. My Code: <script language="javascript" type="text/javascript"> <!-- function popitup(url) { newwindow=window.open(url,'name','toolbar=1,scrollbars=1,location=1,statusbar=0,menubar=1,resizable=1,width=800,height=600'); if (window.focus) {newwindow.focus()} return false; } // --> </script> Any help would be gratefully received! Thanks in advance :)

• How to add a custom loglevel to Python's logging facility

  - by tuergeist

  Hi, I'd like to have loglevel TRACE (5) for my application as I don't think that debug() is enought. Additionally log(5, msg) isn't what I want. The question is, how can I add a custom log level to a Python logger? Actually I've a mylogger.py with the following content: import logging @property def log(obj): myLogger = logging.getLogger(obj.__class__.__name__) return myLogger In my code I use it in the following way: class ExampleClass(object): from mylogger import log def __init__(self): '''The constructor with the logger''' self.log.debug("Init runs") Now I'd like to call self.log.trace("foo bar") Thanks in advance for your help.

• How to make schema and code dynamic?

  - by Jonarch

  I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

• Why is forwarding variadic parameters invalid?

  - by awesomeyi

  Consider the variadic function parameter: func foo(bar:Int...) -> () { } Here foo can accept multiple arguments, eg foo(5,4). I am curious about the type of Int... and its supported operations. For example, why is this invalid? func foo2(bar2:Int...) -> () { foo(bar2); } Gives a error: Could not find an overload for '_conversion' that accepts the supplied arguments Why is forwarding variadic parameters invalid? What is the "conversion" the compiler is complaining about?

• Java Custom exception throw behaves differently between different Projects

  - by Pablo

  I am attempting to call the following in my code: public void checkParticleLightRestriction(Particle parent) throws LightException { if ( parent == null ) { throw new LightException("quantum-particle-restrict.23", this); } In one Project the exception is thrown and the effect is similar to calling "return" whereby I am returned back to the point immediately succeeding where this method was called. However in another Project I get thrown completed out of the current package and to a point way prior to the point preceeding this method. It likes instead of being kicked out of a bar I am being deported all the way out of the country. My option are the wrap the throw in a try / catch but I am wondering why this difference in behaviour beween the 2 projects ?

• Universal control - simple question about dock and anchor

  - by Vytas999

  I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

• Html newbie! background-image question

  - by Kevin Li

  Hi! I'm learning HTML and I wanted to practice by recreating a invoice sent to me by Electronics Expo. However, I used the background-image property and repeated it by repeat-x and now, the background stretches across the page so much that it has a horizontal bar to drag. http://htmlpocketreference.110mb.com/index.html You can see what I did in my link above. Also, I would really appreciate some advice on simplifying my CSS coding. It seems really messy and I have to move every element once something changes. -.- Thanks!

• jQuery $.post & $.append & IE6

  - by Jim

  I'm having a weird problem with jQuery and IE6. Script works on IE7+ and with all other browsers I have tried it. I can't post the full script, but what it does is this: $.post("file.php",{'foo':'bar'},function(data){ $('#target').append(data) }) When I run the code in IE6, #target just shows ? and a white char with a hole in the middle. I have no idea what this second char is. My initial thought was that this was some sort of content-type problem because the file.php just echoes answer without any header information. I added Content-type: text/html with header() but didn't help. Any suggestions?

• Vim, how to scroll to bottom of a named buffer

  - by Gavin Black

  I have a vim-script which splits output to a new window, using the following command: below split +view foo I've been trying to find a way from an arbitrary buffer to scroll to the bottom of foo, or a setting to keep it defaulted to showing the bottom lines of the buffer. I'm doing most of this inside of a python block of vim script. So I have something like: python << endpython import vim import time import thread import sys def myfunction(string,sleeptime,*args): outpWindow = vim.current.window while 1: outpWindow.buffer.append("BAR") #vim.command("SCROLL TO BOTTOM OF foo") time.sleep(sleeptime) #sleep for a specified amount of time. vim.command('below split +view foo') thread.start_new_thread(myfunction,("Thread No:1",2)) endpython And need to find something to put in for vim.command("SCROLL TO BOTTOM of foo") line

• How to not encapsulate Coffeescript

  - by JellicleCat

  I don't know whether all coffeescript compilers wrap their scripts in anonymous functions, but that's what I see Rails doing. How can I disable this encapsulation? I want to put several initializing functions in a single coffeescript file, then call one of them from an on-page <script> tag (so that each page calls a different initializer). This can't be if the initializing functions are encapsulated. Coffeescript initializer functions: initializerA = -> console.log 'foo' initializerB = -> console.log 'bar' On-page code: <script>$(document).ready(initializerA)</script> Sys: coffee-rails 3.2.1, Rails 3.2.3, Ruby 1.9.3

• Rails object inheritence with belongs_to

  - by Rabbott

  I have a simple has_many/belongs_to relationship between Report and Chart. The issue I'm having is that my Chart model is a parent that has children. So in my Report model I have class Report < ActiveRecord::Base has_many :charts end And my Chart model is a parent, where Pie, Line, Bar all inherit from Chart. I'm not sure where the belongs_to :report belongs within the chart model, or children of chart model. I get errors when I attempt to access chart.report because the object is of type "Class" undefined local variable or method `report' for #< Class:0x104974b90 The Chart model uses STI so its pulling say.. 'Pie' from the chart_type column in the charts table.. what am I missing?
