• Redirect print in Python: val = print(arg) to output mixed iterable to file

  - by emcee

  So lets say I have an incredibly nested iterable of lists/dictionaries. I would like to print them to a file as easily as possible. Why can't I just redirect print to a file? val = print(arg) gets a SyntaxError. Is there a way to access stdinput? And why does print take forever with massive strings? Bad programming on my side for outputting massive strings, but quick debugging--and isn't that leveraging the strength of an interactive prompt? There's probably also an easier way than my gripe. Has the hive-mind an answer?

• How could I stop PHP from returning headers when executed from commandline?

  - by JonnyLitt

  This may be a ridiculous question, but it's been bothering me for a while. I have a mail forwarder piped to a PHP script, it receives perfectly, however I have the following error mailed back to me instantly: A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: pipe to |/home/[webroot]/public_html/external/mobile/email.php generated by mobile@[mydomain] The following text was generated during the delivery attempt: X-Powered-By: PHP/5.2.13 Content-type: text/html As you can see, Exim thinks the header response an error from the script I have. The script can receive the Email perfectly from php://stdin but Exim is quick-replying with the error. Plus, It's running from console, not Apache so HTAccess or configuring Apache most likely would do nothing. I can not find any solution, or anyone with the same problem. So my question is: How to I get rid of those two headers? Thanks, ~Jonny

• jquery form validation

  - by kalpaitch

  I am using jquery for a quick and easy form validation My forms use the input's default value as a label and I have a little onfocus and onblur javascript function to show and hide this when the user starts to type: <input name='fnameREG' type='text' id='fnameREG' value='first name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> <input name='lnameREG' type='text' id='lnameREG' value='last name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> My issue with the validation is that when the submit button is clicked the pluggin thinks that all the fields are set because they have a default value. I looked but I couldn't find a supplied method to get round this. Thanks!

• Redirecting user from an old web to another in Sharepoint

  - by BeraCim

  Hi all: I want to add the ability to redirect users when they visit certain old sites. The URL of the old sites are unknown, but the server name is the same, e.g. Old site url: http://sharepoint/mySite/default.aspx New site url: http://sharepoint/myNewSite/... There are a lot of other pages within mySite, most of which must be redirected to the new site, but there are exceptions (e.g. user can still view the documents within the site). I thought I have to do this programmatically by somehow capturing the http request and read the url myself. Being no sharepoint guru, I had a quick google, and found that writing a web part is prehaps the best alternative for my situation. But I'm just wondering, given my situation and needs, is writing a web part, or something programmatically, really the ideal solution? Or is there a faster and quicker way to achieve what I want using Sharepoint? Thanks.

• Regular Expression for finding phone numbers

  - by Rocky

  Hello Everyone, I am new to Stackoverflow and I have a quick question. Let's assume we are given a large number of HTML files (large as in theoretically infinite). How can I use Regular Expressions to extract the list of Phone Numbers from all those files? Explanation/expression will be really appreciated. The Phone numbers can be any of the following formats: (123) 456 7899 (123).456.7899 (123)-456-7899 123-456-7899 123 456 7899 1234567899 Thanks a lot for all your help and have a good one!

• Quickly generate/publish RSS feeds from ASP.NET projects?

  - by jdk

  Under a timeline, therefore the salient point is "quickly" and willing to throw some $ at it too (doesn't have to be a free solution). Looking for an RSS feed generator usuable in .NET framework 2.0. Ideally it would be easy to use (inferred quick) but flexible enough to support the multiple standards (shown part way down this page). We have the business classes in .NET and want to publish RSS feeds on the ASP.NET website. Any software that's good? Doesn't have to be free. Must support .NET framework 2.0 Thanks.

• How to enable a two-finger drag on a mac in Silverlight?

  - by Edward Tanguay

  In a Silverlight 4 application I have a ScrollViewer which I enable the user to scroll with the mouse wheel by using SetIsMouseWheelScrollingEnabled(): <ScrollViewer x:Name="CodeBoxScrollViewerModelSingular" tk:DockPanel.Dock="Left" Style="{StaticResource ScrollViewerCodeBoxStyle}"> <TextBox Text="{Binding SingularModelFileContent}" Style="{StaticResource TextBoxCodeBoxStyle}"/> </ScrollViewer> CodeBoxScrollViewerModelSingular.SetIsMouseWheelScrollingEnabled(true); However, someone tested it on a Mac and said: The only problem I noticed on a quick test was that I couldn't scroll down by using a two-finger drag, which has been standard UI behavior on the Mac for several years now. Is there any way to enable a "two-finger drag" on the Mac as you can enable mouse wheel scrolling?

• How can I vertically center an element with GWT?

  - by Camille

  Perhaps I haven't been searching the right way but I cannot figure out for the life of me how to center an element using GWT Layout Panels. I'm using UiBinder and I've tried all panels that implement HasVerticalAlignment (DockPanel, HorizontalPanel, VerticalPanel). None of them seem to have any impact from setting vertical alignment (or even horizontal). I've made sure they're taking 100% width and height, inspected the resulting DOM layout from my browser and nothing seems to be changed from those properties. The quick and dirty fix I've figured out is to create my own "CenterPanel" widget which basically is a wrapper around a HTMLPanel with a HTML table with a valign="middle" cell. However, this basically feels like a throwback to the classical css-layout middle centering problems. Surely GWT has something to do this that I've completely overlooked?

• How to condense onclick code to be dynamic

  - by opbeta

  I am trying to get this onclick function code to be dynamic. I do not want to have 50 blocks of code for all the states. He is a quick snippet of the code var Ohio=function(){ document.getElementById('texas').style.display='none'; document.getElementById('florida').style.display='none'; document.getElementById('ohio').style.display='block'; } and so on and so forth..... How would I go about condensing this to make it smaller and dynamic?

• Jquery background overlay/alert without .onclick event - php responder?

  - by Philip

  Hi guys, I have no experience with jquery or javascript for that matter. I am trying to implement this technique to respond to users for errors or messages in general. lights-out-dimmingcovering-background-content-with-jquery This method uses the onclick event and that's not what im after, I have tried to replace .onclick with .load but that doesn't seem to work. I'm after a quick fix as I really don't have the time to learn jquery or its event handlers. The goal is to catch any errors or message's and once these are called the alert box is called without any further actions such as .onclick. How my code would look: {PHP} $forms = new forms(); if(count($forms->showErrors) > 0 // or == true) { foreach($forms->showErrors as $error) { print('<p class="alert">'.htmlspecialchars($error, ENT_QUOTES).'</p>'); } }

• Replacing a colour/colours in a movieclip with different colours?

  - by Oli

  I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.

• large images on toolbar

  - by cagi

  Hi to all. Is it possible to have a 32x32 images on toolbar while keeping 16x16 in menu. I created toolbar resource (IDR_TOOLBAR1) and set it's button size as 32x32 and load it: if (!m_wndToolBar.CreateEx(this,...) || !m_wndToolBar.LoadToolBar(IDR_TOOLBAR1 )) { ... } When started toolbar correctly shows large btn images but menu is also enlarged showing 32x32 item images!? How to have menu images as before (small 16x16) My app info: SDI, VS2008 Thanks in advance! P.S. I have noticed an option check box "Large Images" in quick customization dialog under options tab. The dialog is enabled by default in my project. When selecting that option images buttons enlarge instantly, the problem is the new sized images is created from small ones and quality is poor. It would be better if new images list is loaded? Once again thanks in advance!

• How to use AVAudioPlayer to play M4P

  - by SimpleCode

  I want to use AVAudioPlayer to play M4p files from iTunes generator. I could use uiWebView to play it and it worked, but I want to put an image of my choice on the background of the player instead of the "quick time" logo. Can you help me as how to do this? Here is an example of the m4p file I want to play with AVAudioPlayer. http://a801.phobos.apple.com/us/r1000/059/Music/b9/0d/be/mzi.zqnndbil.aac.p.m4p Seriously, big thanks in advance!!

• Using Regex to remove Carriage Returns in a CSV file in Notepad++

  - by Barry

  I have a CSV file I need to clean up. This is a one-time thing so I'd like to do it in Notepad++ if possible. The CSV file has two fields, one of which is wrapped in quotes. I'd like to remove any Carriage Returns from within the quoted field. I was trying to use this pattern but can't get it quite right... (.*)\"(.*)\n(.*)\"(.*) Also correct me if I am wrong, but I presume the "replace with" value would be something along the lines of: \1\2\3\4 Thanks in advance. I'm also open to alternate solutions such as a quick and dirty PERL script.

• why is internet explorer displaying my javascript pagination backwards?

  - by user278457

  Here's a version of the code I'm using, stripped down to just the parts that aren't working. This is all written to generate some basic pagination with jQuery. In Chrome/Safari/Moz, I generate see spans, 1,2,3,4,...,etc When I look in IE7/8, I see etc,...,4,3,2,1 The string seems to be concatenating backwards!! This seems very strange to me, because there's not a whole lot going on in the code here, I can't figure out which bit could be causing problems. Obviously, the 1,2,3,4,...,etc is what I'm aiming for here, so as well as an explanation of why this is an issue, I'd love it if someone could offer a quick fix. myVar = { arr:$.makeArray($('.my_li')) }; var str; str=''; for (s in myVar.arr){ r=parseInt(s,10)+1; str+='<span class="my_class">'+r+'</span>'; } $('#my_other_div').html(str);

• Where can I take an online programming aptitude test/exam?

  - by nbolton

  A potential employer requires me to take an online aptitude test before my interview (in this case the test is for C, from Previsor). Where can I take the same (or similar) test so I have a rough idea on what I should brush up on? I've taken a similar test for C++ previously, so I have some idea of what to expect. I've also been studying my C books thoroughly (especially the required material as described in the PDF), but I feel it would be a good idea to get a feel for the particular test before taking it. I did a quick search on Brainbench, but they don't seem to have a C test, unless I'm mistaken (only C++). Note: I'm happy to pay to take a test if no decent free ones are available.

• Need an alternative to two left joins.

  - by Scarface

  Hey guys quick question, I always use left join, but when I left join twice I always get funny results, usually duplicates. I am currently working on a query that Left Joins twice to retrieve the necessary information needed but I was wondering if it were possible to build another select statement in so then I do not need two left joins or two queries or if there were a better way. For example, if I could select the topic.creator in table.topic first AS something, then I could select that variable in users and left join table.scrusersonline. Thanks in advance for any advice. SELECT * FROM scrusersonline LEFT JOIN users ON users.id = scrusersonline.id LEFT JOIN topic ON users.username = topic.creator WHERE scrusersonline.topic_id = '$topic_id' The whole point of this query is to check if the topic.creator is online by retrieving his name from table.topic and matching his id in table.users, then checking if he is in table.scrusersonline. It produces duplicate entries unfortunately and is thus inaccurate in my mind.

• Custom Data Types

  - by Tinkerer_CardTracker

  Hello, quick question: I'd like to create some custom data types, but I don't think I'm asking the right question(s). There are "compound Boolean" values used throughout .NET, and I want to design some of my own. I've been using a series of Boolean variables, which works, but just isn't the same. Examples from .NET include: Color.Black Alignment.Centered [fontProperties].Bold* *I forget the actual name, but you get the idea I want to make something like this: ColorSortQualities None DistinguishColor DistinguishNumberOfColors DistinguishColorPattern Once that's been declared, I could do this: if(searchOptions.ColorSortQualities == DistinguishColor) [do stuff] What is this called? Thanks!

• facebook iphone app architecture

  - by xoail

  does anyone know or predict how facebook's iphone app architecture could look like? More specific to what could be built into the app (client) what could be rendered on demand? Do you think the main menu layout of the app (where all the navigation buttons are there) are on the client or being rendered dynamically? Similarly apps like NYTimes or US News, what portion is done on the client and what is rendered dynamically. What could be the best way to render things on-demand. Would it be ok to use to UIWebView and render most of the app in it? A quick overview would help. Thank you!

• Best way to deal with multiple layouts in symfony

  - by Pierre

  Hey folks. I'm looking for the best way to do something simple in symfony. Basically, I have a module in which all the pages will contain the same header and footer. That module also shares the same general layout as the other modules. I'm just wondering, should I create one file and have my content pages called up as partials or should all files have their own content and somehow call the two other templates. I made a quick example of my setup: http://grab.by/3Riy Hopefully, it'll help understand what I'm trying to do. Thanks!

• Is it valid to have more than one question mark in a URL?

  - by Bungle

  I came across the following URL today: http://www.sfgate.com/cgi-bin/blogs/inmarin/detail??blogid=122&entry_id=64497 Notice the doubled question mark at the beginning of the query string: ??blogid=122&entry_id=64497 My browser didn't seem to have any trouble with it, and running a quick bookmarklet: javascript:alert(document.location.search); just gave me the query string shown above. Is this a valid URL? The reason I'm being so pedantic (assuming that I am) is because I need to parse URLs like this for query parameters, and supporting doubled question marks would require some changes to my code. Obviously if they're in the wild, I'll need to support them; I'm mainly curious if it's my fault for not adhering to URL standards exactly, or if it's in fact a non-standard URL.

• How to handle concurrency control in dynamic data?

  - by Andrew

  I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

• Doing a join across two databases with different collations on SQL Server and getting an error.

  - by Andrew G. Johnson

  I know, I know with what I wrote in the question I shouldn't be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn't aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it's a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all "normal" latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need. Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases. Exact error is: Cannot resolve the collation conflict between "SQL_Latin1_General_CP850_CI_AI" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

• Is there a way to import or convert vmware player images to run on xen?

  - by Shamgar

  It's fairly popular for companies offering a quick way to test their product to give you a vmware player image. I don't run VMWare though, I run Xen exclusively. Most of these images (and the one I'm interested right this moment particularly) are linux images. Is there a way to use this image with Xen? Obviously, I could setup player long enough to boot the image, then move the data out of the image to a Xen image, but I'm hoping for something easier and quicker than that...preferably that doesn't require setting up a box to run player than can run this image.

• Problem with ranking of search results in SharePoint 2007 if using the CONTAINS predicate

  - by mythicdawn

  While writing a front-end for the SharePoint Search web service for work, I did some quick testing with the MOSS Search Tool to make sure things were working right under the hood. What I found was that queries composed only of CONTAINS predicates (FREETEXT ones were fine) would have a rank of 1000 for any results that were returned. According to the documentation (http://msdn.microsoft.com/en-us/library/ms544086.aspx): "If the query returns a document because a non–full-text predicate evaluates to TRUE for that document, the rank value is calculated as 1000." Given that the behaviour I am seeing seems to contradict the documentation, is it the case that all queries that use only the CONTAINS predicate will produce ranking like this?
