• How do I change the number of thumbnails seen in the Android sample Home application?

  - by Todd

  I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

• Copy a value based on criteria Salesforce

  - by Robert

  Hi all, On a Salesforce.com opportunity I have a number of custom fields that are potential options that the end client will eventually select. Option 1 (Desc Field) Option 1 (Value) Option 2 (Desc Field) Option 2 (Value) Option 3 (Desc Field) Option 3 (Value) At a future point the user will ultimately choose one of the options as the preferred option. What I want is then the value for the chosen option to be stored in another field without the user having to enter it again. A “nice to have” would also be that all 3 option descriptions, values and selected value are locked once this is done. Any ideas?

• Match a word with similar words using Solr?

  - by fayer

  I want to search for threads in my mysql database with Solr. But i want it to not just search the thread words, but for similar words. Eg. if a thread title is "dog for sale" and if the user searches for dogs the title will be in the result. and also if a user searches for "mac os x" the word "snow leopard" will appear. and the ability to link words the application thinks is related eg. house and apartment. how is this kind of logic done? i know that you can with solr look up words in a dictionary file you create/add, so solr will look for dogs and see what related words there are (eg. dog). but where do you find such a dictionary? i have no idea about this kind of implementation. please point me into right direction. thanks

• Java Double Array

  - by user1062058

  I'm having trouble setting up and placing values into an array using a text file containing the floating point numbers 2.1 and 4.3 each number is separated by a space - below is the error I'm getting: Exception in thread "main" java.util.NoSuchElementException import java.util.*; import java.io.*; public class DoubleArray { public static void main(String[] args) throws FileNotFoundException { Scanner in = new Scanner(new FileReader("mytestnumbers.txt")); double [] nums = new double[2]; for (int counter=0; counter < 2; counter++) { int index = 0; index++; nums[index] = in.nextDouble(); } } } Thanks, I'm sure this isn't a hard question to answer... I appreciate your time.

• Prevent Excel from evaluating unneeded expressions in OR()

  - by Wesley

  IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

• What is your favorite new feature in php 5.3?

  - by Kris

  I'm trying to compile a list of new features found in php 5.3. that I have to check out as time permits. I'd like to do this in the order of usefulness of the features.

Such a list would hopefully be useful to many and the I have not been able to find one on SO. Please name one specific feature per answer, thanks in advance!

• will destroyed() be emitted if the constructor of a class derived from QObject throws?

  - by PorkyBrain

  Ive seen Qt GUI syntax like the following all over the place: myDialog::myDialog(QWidget *parent, Qt::WFlags flags):QDialog(parent, flags) { QPushButton *button = new QPushButton("&Download", this); QVBoxLayout *layout = new QVBoxLayout(this); //something that can throw here layout ->addWidget(button ); setLayout(layout); } I've always wondered if this can leak in the event of an exception because the "this" I'm giving as a parent to button and layout is not fully constructed so it might not destroy its children. I tried it out in MSVC2010 Qt4.8.3 and it looks like as soon as the base QObject class is fully created (which is done first of course) it is ok to pass "this" to other objects in the constructor, they will destroyed correctly. I haven't found the spot in the Qt docs guaranteeing this though, can someone point me to it so I have assurance that this will not change in the future?

• Method for demonstrating iPad application in online meetings

  - by competent_tech

  We have recently developed an iPad application and now need to start demonstrating it to customers and prospects as part of our overall product suite during webinars. As part of our Agile methodology, we also need to periodically review the application with key customers without having to distribute it since the application is not a standalone application and requires a connection to web services installed at each customer site. We have searched high and low for any solution that doesn't involve rooting the device but have been unable to find one. The most common suggestion seems to be to point a webcam at the device, but that comes across as very unprofessional. I know that there are VGA out adapters that can be plugged into the iPad and we have used these to present through a projector when the customer is physically present, but this is a relatively rare occurrence. Perhaps there are solutions that we are unaware of that can be used to send VGA output back into a desktop device for screen sharing?

• What's this UI pattern called?

  - by Bears will eat you

  I'm trying to figure out what this sort of thing is called, and eventually how I can create one in a web browser. It looks like this (screenshot of the first app that came to mind): The specific component/pattern I'm looking for is the two list boxes ("Included Gear" and "Excluded Gear") that represent inclusion/exclusion of items from a set. I'm not really looking for the WPF name (if there is one) but it might be helpful. I am looking for the name of this thingy, if there is one, and if you really want to make my day, you can point me toward a jQuery or YUI way of making one of these dealies in a browser. In case you were wondering, the screenshot is a World of Warcraft gear optimization program. Go figure why it was the first program that came to mind when I was trying to think of an example.

• jQuery on/delegate correct syntax

  - by KryptoniteDove

  As the jQuery API is currently down, is anyone able to assist me with the below? I am ajax loading an unordered list into the web page and need to be able to attach hover and click events to the list items. <ul> <li class="option">Item 1</li> <li class="option">Item 1</li> <li class="option">Item 1</li> </ul> So far I have tried a few variations of the below jQuery code using .on for version 1.7+ $("ul").on("click", "li .option", function(){ alert($(this).text()); }); Can anyone point me in the right direction? I'm aware that .live has been depreciated and that .delegate has been superceeded so really only looking for a solution that will allow me to use .on. Thanks as always!

• need to changed markup with jquery

  - by user357034

  I have the following markup which I do not have direct access to... <a href="javascript:void(0);" onclick="window.open('/BulkDiscounts.asp?ProductID=318&ProductCode=' + escape('LB30X40ES') + '&Orig_Price=22.95', 'Discounts', 'scrollbars,status,resizable,width=330,height=300');"><iimg src="/v/vspfiles/templates/100/images/buttons/btn_quantitydiscounts.gif" border="0" align="absmiddle"></a> I need to "rewrite" the above as follows... A few things to point out is that the title is coming from a variable escape(global_Current_ProductCode) variable=productcode in the case above it is LB30X40ES The height and weight, price and product id used in the second markup must be from the first markup. Note that these change depending on the product loaded. These are not constants. I would guess the first thing to do was to add the thickbox class. Then I am lost as to what to do next. Basically I need to open up an thickbox iframe with the modified markup.

• htaccess rewrite; Should I change all relative links or not?

  - by Camran

  I have a rewrite in htaccess which makes this: domain.com/ad.php?ad_id=bmw_m3_328942948 into this: domain.com/ads/bmw_m3_328942948 Problem is the links which are relative to the file wont work... for instance if a link is pointing at '/bin/edit.php' like this originally: domain.com/bin/edit.php // WORKS but after the rewrite the link wants to point here instead: domain.com/ads/bin/edit.php // NOT WORK - NOTE THE /ads/ DOESN'T EXIST IN REALITY Do you understand my issue? What is done about this? Do I have to make ALL links using the newer rewritten format? .htaccess: Options +FollowSymLinks Options +Indexes RewriteEngine On RewriteCond %{REQUEST_URI} !^/ad\.php RewriteRule ^annons/(.*)$ ad.php?ad_id=$1 [NC,L] Thanks

• Catch all javascript errors and send them to server

  Hi everyone, i wandered if anyone had experience in handling javascript errors globally and send them from the client browser to a server. I think my point is quite clear, i want to know every exceptions, errors, compilation errors, ... that happens on the client side and send them to the server to report them. I'm mainly using mootools and head.js (for the js side) and django for the server side (not that it matters...). Thank you for your help. Regards.

• Inter-rater agreement (Fleiss' Kappa, Krippendorff's Alpha etc) Java API?

  - by adam

  I am working on building a Question Classification/Answering corpus as a part of my masters thesis. I'm looking at evaluating my expected answer type taxonomy with respect to inter-rater agreement/reliability, and I was wondering: Does anybody know of any decent (preferably free) Java API(s) that can do this? I'm reasonably certain all I need is Fleiss' Kappa and Krippendorff's Alpha at this point. Weka provides a kappa statistic in it's evaluation package, but I think it can only evaluate a classifier and I'm not at that stage yet (because I'm still building the data set and classes). Thanks.

• C++ - Efficient way to iterate over the contents of a vector?

  - by Francisco P.

  Hello, everyone! I am implementing a text-based version of Scrabble for a college project. I have a vector containing around 400K strings (my dictionary), and, at some point in every turn, I'm going to have to check if any word in the dictionary can be formed with the pieces in the player's hand. My only solution to this is iterating through the string, one by one, and using a sub-routine I have to check if the string in question can be formed from the player's pieces. I'll implement a quickfail checking if the user has any vowels, but it'll still be woefully inefficient. Any suggestions? Thanks for your time!

• C++ - How to efficiently find out if any string in a vector can be assembled from a set of letters

  Hello, everyone! I am implementing a text-based version of Scrabble for a college project. I have a vector containing around 400K strings (my dictionary), and, at some point in every turn, I'm going to have to check if there's still a word in the dictionary which can be formed with the pieces in the player's hand. I'm checking if the player has any move left... If not, it's game over for the player in question... My only solution to this is iterating through the string, one by one, and using a sub-routine I have to check if the string in question can be formed from the player's pieces.

• SharePoint Returning a 401.1 for a Specific User/Computer

  - by Joe Gennari

  We have a SharePoint Services 3.0 site set up supporting about 300 users right now. This report is isolated and has never been duplicated. We have one AD user who cannot log into the SharePoint site with his account from his machine and is subsequently returned a 401.1 error. If any other user tries to log on with their account from his machine, it works okay. If he moves to another machine and logs on, it works okay. The only solution to this point has been to install FireFox on the machine. When he authenticates with FF, everything is okay. Remedies tried so far: Cleared cookies/cache Turned off/on Integrated Windows Authentication in IE Downgraded IE 8 to IE 6 Removed site from Intranet Sites zone Renamed the machine Disjoined/Rejoined Domain

• Learn C++ after learning C#

  - by RichK

  I'm developing a library in C# at the moment and recently bought a great book to help me out but the code snippets are in C++. Does anyone have a link to a site/PDF that'll give me a crash course in C++? (mainly the syntax rather than pros/cons etc) because I'll be developing in C# but things like -, ::, &, **, are giving me the shivers. Obviously the languages aren't 100% compatible but if I know what the C++ is doing from a 'theoretical' point of view I can make a stab at rewriting it in C#. I've had a Google to find the answer but all the sites seem to be "Should I use C++ or C#?", which isn't any good to me. Thanks in advance.

• I want to make a 2D color plot showing stress magnitude (S) at very loctaion (x, y) based on continuous color change using limited data sets

  - by Alex Liu

  friends, I have to trouble you as I couldn't find a solution after trying for a long time. I have 3 columns of data. x, y, and the stress value (S) at every point (x, y). I want to generate a 2D color plot displaying continuous color change with the magnitude of the stress (S). The stress values increase from -3*10^4 Pa to 4*10^4 Pa. I only have hundreds of data sets for an area, but I want to see the stress magnitude (read from the color) at every location (x, y). What Matlab command should I use? Thank you very much! I want to make a 2D color plot showing stress magnitude (S) at very loctaion (x, y) based on continuous color change using limited

• What do I do with a Concrete Syntax Tree?

  - by Cap

  I'm using pyPEG to create a parse tree for a simple grammar. The tree is represented using lists and tuples. Here's an example: [('command', [('directives', [('directive', [('name', 'retrieve')]), ('directive', [('name', 'commit')])]), ('filename', [('name', 'f30502')])])] My question is what do I do with it at this point? I know a lot depends on what I am trying to do, but I haven't been able to find much about consuming/using parse trees, only creating them. Does anyone have any pointers to references I might use? Thanks for your help.

• Reading a variable messes it up?!?!

  - by EpsilonVector

  We have the following line of code: printf("%d\n", toc->runlist.next); printf("%d\n", toc->runlist.next); These are the definitions: typedef struct thread_overview_control{ int id[NR_UTHREADS]; list_t runlist; int active_counter; int main_thread; int need_resched; } thread_overview_control; thread_overview_control* toc; What I'm trying to do is implement user threads. For some reason the output of the above code at the point where our test run crushes is: 12345678 //some address 0 //NOW IT'S NULL?!?!?! How can this happen?? All we do is read a variable. And the strange thing is, without printf's there are no crashes. What's going on?

• About a Class Object

  - by Chicko Bueno

  I have a very basic question about a class object. After the class has been created, we need to create a class object. At this point, I'm a bit confused to make either *object or object. Example: CClass object CClass *object What is the difference both of them? And to access class function i need to use dot '.' and arrow '->'. I know dot and arrow used to access class function, but what is the significant meaning for both dot and arrow?
