• Solr dataimport skips entities in my data-config.xml

  - by lerhaupt

  My data-config.xml defines 3 different entities under the document tag (lets call them foo, bar and baz). When I issue a basic full import localhost:8983/solr/dataimport?command=full-import, only 2 of the 3 entities get indexed (foo and bar are in my index but baz never makes it). However, if I then issue a command to just import baz via localhost:8983/solr/dataimport?command=full-import&entity=baz&clean=false it adds baz documents just fine and the index then has all 3 types. Does anyone have any thoughts on why one entity gets skipped in the general data import but then still works okay if I specifically call it out? Is there an error/warning log I can check? Nothing bad shows up in /solr/logs/ but those just appear to be request logs.

• Mapping a drop-down menu over an image

  - by Pieter

  I have a menu bar that is rotated slightly. Here are two buttons as an example: As a result, I can't use regular HTML to handle this. I need to use a <map> to put hyperlinks over the menu parts. (Or am I missing a killer CSS feature I don't know about?) I want to map drop-down menus to these buttons. This looks like a nice way to implement drop-down menus: http://javascript-array.com/scripts/simple_drop_down_menu/ However, this does not work on <map>s, I believe. Or am I wrong? Is there a different approach I can take to constructing drop-down menus for a menu bar that is not aligned horizontally?

• Win32 Window Menu is appearing along left side instead of across top of window

  - by Khat

  I think I may be using a wrong window style or something or maybe just adding the menu to the window incorrectly. I'll post a link to an image here so you can see what I mean about the menu not diplaying correctly: http://img707.imageshack.us/img707/4828/wtfmenu.jpg And here's a link to the code that creates the menu and the window: http://pastebin.com/CBrSVXUD I'm sure I'm missing something simple and dumb in the labyrinth of styles, settings and etc that are part and parcel for the Win32 API. Has anyone seen this before and know what I'm doing wrong? I just want a 'normal' menu bar along the top, snug against the title bar. Thanks in advance for any advice.

• Is there a Java method that encodes a collection of parameters as a URL query component?

  - by Steven Huwig

  Is there a widely-used Java library that does something like what dojo.objectToQuery() does? E.g. (assuming the use of HttpCore's HttpParams object, but any key-value mapping will do): HttpParams params = new BasicHttpParams() .setParameter("foo", "bar") .setParameter("thud", "grunt"); UnknownLibrary.toQueryString(params); should yield "foo=bar&thud=grunt". I know it's not hard to write but it seems like it should have already been written. I just can't find it.

• Alternative to Page_Load in ASP.NET (and a good WTF story)

  - by Jason

  Woo, I have a doozy of a problem (might even be one for the Daily WTF) and I'm hoping there's a solution. (My apologies for the long post...) I have been working on a website that I inherited about a month ago. One of the parts I have been working on is fixing one of the controls (essentially a dynamic header bar) so that it displays additional information as requested by my users. As part of doing this project, I created a Site.master file so that I wouldn't have to recode the header bar into every single page. When I first started doing this, it seemingly worked very well. All the pages I had developed looked great and the bar updated as it should displaying the information as it should. Well, when I dropped the Site.master (and this control) into older site pages (ones I did not specifically develop) I noticed that it looked bad on some of them, but not all of them. When I say it looked bad, basically, the control would left-align itself to the page rather than center as it should. I spent a couple hours debugging to no avail - CSS looked correct, the HTML appeared to be okay, I didn't see anything in the Javascript (although, I did miss something as I'll point out in a second), and even the old code looked correct (to the best that it could - it's not very well written). Another coworker took a look at the site and couldn't find anything at first, either. It wasn't until I just thought to look at the rendered source code of the page (I had been working in the developer view up to this point in IE8) that it became clear what was wrong. The original developer performs searches on many of the pages. To accomplish this, he queries the database for ALL the data and then loads them into Javascript arrays within the page so he can get access to them. This in itself is a huge problem because we're talking about thousands of items, and it obviously isn't scalable (and, yes, the site is slow). However, it finally clicked what was screwing up the Site.master - when he loads the data into the Javascript arrays, he writes out the data to the HTML upon Page_Load using numerous Response.Write(string) calls. The WTF (and what was messing me up) is that he inserts the Javascript before the DOCTYPE causing IE to go into quirks mode! So, because I need to at least get this release out (I'll fix the real problem later), I was wondering: is there a way I can force this Javascript to be inserted elsewhere into the HTML—after the DOCTYPE at the very least? Right now, all the Response.Write() calls are being done in the Page_Load method. I just need them to be inserted later.

• External class-calling

  - by anonymous

  Hi guys i have a bit of a problem with a few classes, and i would be very grateful if someone can help me out. So i have: Already compiled executable (for whom i don't have the source) A class in that program that i want to call The program doesn't have export for the class, and that's my problem i don't have definition for this class, so is there a way to get a callback to this class? Example: In the compiled executable: foo::bar (example) { printf(example); } My app: CALLBACK(foo::bar, "this text must be passed as argument") Or in other words i want to call a class in other executable (without having its source) and pass arguments to its function.

• automake and custom rpath

  - by scai

  I have to ship a third-party library with an application. Because I don't want to set LD_LIBRARY_PATH by hand or require any wrapper script I want automake to set a custom rpath. Unfortunately libtool has its own -rpath option and adding -Wl,-rpath,/foo/bar to LDFLAGS only results in g++: unrecognized option '-rpath' because libtool seems to get confused with the command line options. The same happens with the alternative form -Wl,-rpath -Wl,/foo/bar. Is there any way to specify a custom rpath without libtool interference?

• Chrome Extension Manifest 'Matches'

  - by Aristotle

  I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts. { "name": "My Extension", "version": "1.0", "description": "My Extension Experiment", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "default_popup": "popup.html" }, "content_scripts": { "matches": ["http://*"], "js": ["scripts.js"] } } When I try to load this extension into Chrome, I get the following message: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.Invalid value for 'content_scripts'. I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what? update After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax: "content_scripts": [{ "matches": ["http://*"], "js": ["scripts.js"] }] That being said, I still get the following error when trying to load my extension: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'. Invalid value for 'content_scripts[0].matches[0]'.

• How to share a variable between two classes?

  - by Altefquatre

  How would you share the same object between two other objects? For instance, I'd like something in that flavor: class A { private string foo_; // It could be any other class/struct too (Vector3, Matrix...) public A (string shared) { this.foo_ = shared; } public void Bar() { this.foo_ = "changed"; } } ... // inside main string str = "test"; A a = new A(str); Console.WriteLine(str); // "test" a.Bar(); Console.WriteLine(str); // I get "test" instead of "changed"... :( I read there is some ref/out stuff, but I couldn't get what I'm asking here. I could only apply some changes in the methods scope where I was using ref/out arguments... I also read we could use pointers, but is there no other way to do it?

• Sort a set of multidimensional arrays by array elements

  - by Joseph Carrington

  Let's say I've started here: $arr[0] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'bar', 'int' => 12); And I want to get here: $arr[0] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'bar', 'int' => 12); How can I sort the elements in an array by those elements elements? Multidimensional arrays always feel like a little bit more than my brain can handle (-_-) (until I figure them out and they seem super easy)

• C: Incompatible types?

  - by Airjoe

  #include <stdlib.h> #include <stdio.h> struct foo{ int id; char *bar; char *baz[6]; }; int main(int argc, char **argv){ struct foo f; f.id=1; char *qux[6]; f.bar=argv[0]; f.baz=qux; // Marked line return 1; } This is just some test code so ignore that qux doesn't actually have anything useful in it. I'm getting an error on the marked line, incompatible types when assigning to type ‘char *[6]’ from type ‘char **’ but both of the variables are defined as char *[6] in the code. Any insight?

• Ant: make "available" throw an understandable error?

  - by digitala

  When running ant, how do I make an <available /> block throw an adequate error message? This is what I have so far: <target name="requirements"> <available classname="foo.bar.baz" property="baz.present" /> </target> <target name="directories" depends="requirements" if="baz.present"> <mkdir dir="build" /> </target> <target name="compile" depends="directories"> <!-- build some stuff --> </target> What I'm currently seeing when requirements fails is a message complaining about the ./build dir not being available. How can I change this so that a message is displayed about the missing class, such as "foo.bar.baz is not available"?

• Loading...Please wait for UIWebView - iPhone

  - by niha7229

  Hi guys, In Safari and other browsers, there is a bar that would indicate the percentage of the loading progress, and I, myself, trying to implement something similiar on iPhone, when loading some content in UIWebView, I would like the app to indicate the percentage of the page being loaded. I tried some google search and realize we could use NSURLConnection to read only the header and get the Content-Length ( but don't know how to, I read the Apple's NSURLConnection docs but probably I missed something ... ). And the size ( kb ) which UIWebView had loaded, seem like UIWebView don't support it for the public API... I hope this would be complete in some other ways than I thought, so if you have any ideas, please throw it out, thanks for your patient reading. P.S : I could just show an Activities Indicator for users with the long loading progress actions of the UIWebView but I just want to go further with the loading percentage bar :). Regards.

• Is there a difference between Perl's shift versus assignment from @_ for subroutine parameters?

  - by cowgod

  Let us ignore for a moment Damian Conway's best practice of no more than three positional parameters for any given subroutine. Is there any difference between the two examples below in regards to performance or functionality? Using shift: sub do_something_fantastical { my $foo = shift; my $bar = shift; my $baz = shift; my $qux = shift; my $quux = shift; my $corge = shift; } Using @_: sub do_something_fantastical { my ($foo, $bar, $baz, $qux, $quux, $corge) = @_; } Provided that both examples are the same in terms of performance and functionality, what do people think about one format over the other? Obviously the example using @_ is fewer lines of code, but isn't it more legible to use shift as shown in the other example? Opinions with good reasoning are welcome.

• Does Windows 7 have a Kiosk Mode?

  - by Jordan

  I'm writing a Kiosk on a Windows 7 computer. The Kiosk is on a touch screen computer, that will not have a keyboard. The application is a WPF application running the .NET Framework version 3.5. I'm having problems with the progress bar task bar showing up (blinking) at the bottom of the screen. This unfortunately gives the user access to the background operating system. Is there someway to lock a full screen application window into the front of the screen without using it on-top-of-everything mode. Some sort of Kiosk mode, or some tool that was designed for this.

• In Javascript, by what mechanism does setting an Image src property trigger an image load?

  - by brainjam

  One of the things you learn early on when manipulating a DOM using Javascript is the following pattern: var img = new Image(); // Create new Image object img.onload = function(){ // execute drawImage statements here } img.src = 'myImage.png'; // Set source path As far as I know, in general when you set an object property there are no side effects. So what is the mechanism for triggering an image load? Is it just magic? Or can I use a similar mechanism to implement a class Foo that supports a parallel pattern? var foo = new Foo(); // Create new object foo.barchanged = function(){ // execute something after side effect has completed } foo.bar = 'whatever'; // Assign something to 'bar' property I'm vaguely aware of Javascript getters and setters. Is this how Image.src triggers a load?

• Perform Push Segue From a Tab View Controller

  - by user1416492

  I have a Tab Bar Controller App, the tab bar controller is forked into several "tab" view controller, in one of the view controller I want to redirect the user to an other view controller. I create a segue from that tab view controller to the destination view controller and given it an Identifer. And I call "performSegueWithIdentifier" in "viewDidAppear" to redirect the user. It works fine when the segue is "Modal", however since I want to retain the tabs, I want to call the segue through "Push". However, once I change the segue to "Push", it is not working anymore (it does not try to go to the destination view controller). The app did not crash on the simulator but just staying on the origin tab view controller.

• Why doesn't TextBlock databinding call ToString() on a property whose compile-time type is an interf

  - by Jay

  This started with weird behaviour that I thought was tied to my implementation of ToString(), and I asked this question: http://stackoverflow.com/questions/2916068/why-wont-wpf-databindings-show-text-when-tostring-has-a-collaborating-object It turns out to have nothing to do with collaborators and is reproducible. When I bind Label.Content to a property of the DataContext that is declared as an interface type, ToString() is called on the runtime object and the label displays the result. When I bind TextBlock.Text to the same property, ToString() is never called and nothing is displayed. But, if I change the declared property to a concrete implementation of the interface, it works as expected. Is this somehow by design? If so, any idea why? To reproduce: Create a new WPF Application (.NET 3.5 SP1) Add the following classes: public interface IFoo { string foo_part1 { get; set; } string foo_part2 { get; set; } } public class Foo : IFoo { public string foo_part1 { get; set; } public string foo_part2 { get; set; } public override string ToString() { return foo_part1 + " - " + foo_part2; } } public class Bar { public IFoo foo { get { return new Foo {foo_part1 = "first", foo_part2 = "second"}; } } } Set the XAML of Window1 to: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <Label Content="{Binding foo, Mode=Default}"/> <TextBlock Text="{Binding foo, Mode=Default}"/> </StackPanel> </Window> in Window1.xaml.cs: public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new Bar(); } } When you run this application, you'll see the text only once (at the top, in the label). If you change the type of foo property on Bar class to Foo (instead of IFoo) and run the application again, you'll see the text in both controls.

• Android Animate Rotate

  - by oriharel

  I did some digging in Android code, and saw the use of in the indeterminate progress bar. after trying to create my own drawable with this tag: <animated-rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/spinner_pia" android:pivotX="50%" android:pivotY="50%" android:framesCount="12" android:frameDuration="100" /> I get an error: "No resource identifier found for attribute 'frameDuration' in package 'android'" - which means that frameDuration is a private attribute. Is there a way to use this "animate-rotate" feature? My task is to replace the system's default indeterminate progress bar. I'd like to do it with as little code as possible (just change few attributes if possible). Using the ProgressBar view, setting: android:indeterminateOnly="true" android:indeterminateBehavior="cycle" android:indeterminateDuration="3500" android:indeterminateDrawable="@drawable/pia_sivuvator" and point "@drawable/pia_sivuvator" to that object would've make my task as elegant as they come but I'm stuck on those private attributes. help?

• MYSQL Event Scheduler DELIMITER using PHP

  I'm having an issue with my PHP code trying to create events within MySQL. I begin with creating a string like this: $sql="DELIMITER $$ CREATE EVENT `$test_name` ON SCHEDULE EVERY $time1 $sched2 STARTS '$start_date $start_time' DO BEGIN "; $sql .="INSERT INTO blah (foo,bar); "; $sql .="END$$ DELIMITER ;" mysql_query($sql,$dbh); But I keep getting Syntax Errors starting with DELIMITER $$ CREATE EVENT. Without the semicolon behind (foo,bar); the event triggers with a unexecuted payload. Any ideas on where I'm going wrong? Thanks!

• How do I copy an object in Java?

  - by Veera

  Consider the below code: DummyBean dum = new DummyBean(); dum.setDummy("foo"); System.out.println(dum.getDummy()); // prints 'foo' DummyBean dumtwo = dum; System.out.println(dumtwo.getDummy()); // prints 'foo' dum.setDummy("bar"); System.out.println(dumtwo.getDummy()); // prints 'bar' but it should print 'foo' So, I want to copy the 'dum' to dumtwo' and I want to change 'dum' without affecting the 'dumtwo'. But the above code is not doing that. When I change something in 'dum', the same change is happening in 'dumtwo' also. I guess, when I say dumtwo = dum, Java copies the reference only. So, is there any way to create a fresh copy of 'dum' and assign it to 'dumtwo' ?

• Forcing Flex to update the screen?

  - by ABBarton

  This may be a bit of a beginners question, but I can't for the life of me figure it out. I'm using flex to develop a GUI for a large project, specifically a status bar along the bottom. Within my StatusBar class is a ProgressBar, which other classes doing work can tell to update(change bar completion and label) as they progress. The problem I'm encountering is that flex won't update whats shown on the screen until it's too late, for example ProgressBar initialized, 0% done some class sets the ProgressBar to be 12% done some class does some work some class sets the ProgressBar to be 56% done Whats happening is the 12% done is never displaying, it just hangs at 0% during the work, then skips right to 56% done. I've tried to understand the lifecycle of a flex component (invalidation and validation), and I think I understand it and am applying it correctly, but it's not working at all. I need to tell flex to redraw my StatusBar (or at least the ProgressBar within) after some class sets it to be 12% done, but before some class starts doing its work. How do I do this?

• .htaccess newb - RewriteRule not matching 2nd rule, why?

  - by jyoseph

  I am currently migrating from isapi_rewrite to .htaccess. I'm having some difficulty and I think it's something basic, but I'm not terribly familiar with .htaccess. I have the two rules like so: RewriteRule ^testing/ /test/index.html?test=1 [NC] RewriteRule ^testing/foo-bar/ /test/index.html?test=2 [NC] Yet the second rule never matches. If I go to http://mydomain.com/testing/foo-bar/ then I will only see the first rule. Why is that? And can it be easily fixed? I have many rules (outputted from the database to write the .htaccess file )and ordering them in a particular order isn't really possible.

• Better method for flipping multidimensional array?

  - by sudowned

  I've retrieved some data from the database, which is in the following structure: [0] [item_id] = 197 [dice_chat_css] = "foo" [dice_image] = "bar.png" [1] [item_id] = 128 [dice_chat_css] = "foo" [dice_image] = "bar.png" The most convenient and computationally inexpensive way for me to pass this data to the rest of my (PHP) application is with item_id as the index, because it saves having to loop over the array to look up values. If this was a flat array, I could accomplish this trivially with array_flip, but since it isn't, it's my pick of using either the multidimensional array_flip listed in the comments on PHP.net, or roll my own logic: for ($i = 0; $i < sizeOf($r); $i++){ $s[$r[$i]['item_id']]['dice_image'] = $r[$i]['dice_image']; $s[$r[$i]['item_id']]['dice_chat_css'] = $r[$i]['dice_chat_css']; } I know it's simple, but it feels like I'm reinventing the wheel here. Is there an accepted, more optimized method available or am I being weird about this?

• Updating Label on previously loaded view?

  I am working on a simple app tab-bar based application that has two views. The first is the main application and the second is a simple instruction screen. What I am trying to do is create a update a label on that second screen as things change in the main app. Because the second screen is only simple with one label and some text I am not unloading it once its loaded. After the first viewDidLoad I can update the label just fine, but after that is there a way to catch successive view switches from the tab-bar menu so I can update the label? many thanks gary
