• How to get the LAN IP of a client using Java?

  - by Henrik

  How can i get the LAN IP-address of a computer using Java? I want the IP-address which is connected to the router and the rest of the network. I've tried something like this: Socket s = new Socket("www.google.com", 80); String ip = s.getLocalAddress().getHostAddress(); s.close(); This seem to work on some cases, but sometimes it returns the loopback-address or something completely different. Also, it requires internet connection. Does anyone got a more accurate method of doing this?

• How do I show/hide an element in YUI as in jQuery?

  - by Chad Johnson

  In jQuery, when I want to show or hide something, I do this: $('#elementId').show(); $('#elementId').hide(); How do I do this with YUI? I've tried YAHOO.util.Dom.get('elementId').hide(), asked my co-workers, looked at the documentation, and searched Google, and I've found nothing helpful. From the documentation, it looks like this should work YAHOO.util.Dom.get('elementId').setStyle('display', 'none') but of course it does not. All I can think of is this, which sucks because then I'm not using a framework: document.getElementById('elementId').style.display = 'none';

• NSURL not instantiating properly

  - by taokakao

  Hi, I am new to IPhone developing. I have got very strange issue with NSURL which is driving me crazy. I want to instantiate NSURL object to use it in loading image. But instantiation never happens in proper way. It always says my url in invalid. Basically I use code like below: NSString *str = @"http://google.com"; NSURL *url = [NSURL URLWithString:str]; but I also have tried a lot of different modifications (with CFStringRef + CFURLCreateStringByAddingPercentEscapes and so on). All of them are not working for me. In debugger url is set to "Invalid". What it could be? I don't think this is algorithmic or environment issue. It could be about some settings? Have anyone any idea of what happens?

• How does Twitter for iPhone bookmarklet work?

  - by Igor Zevaka

  Twitter client (formerly Tweetie) allows you to define a bookmarklet in Safari that launches the app. I want to know which iPhone API allows you to register the protocol specifier (or whatever it's called) - in this case "tweetie:" - in order for this bookmarklet to work. The instructions can be found here and the bookmarklet itself is below. javascript:window.location='tweetie:'+window.location Clicking the above bookmark is the same as typing in "tweetie:http://google.com" into the address bar. This is obviously supported on the OS/Browser level, much the same as tel: URIs. Am I correct in understanding that developers can add arbitrary URI protocol specifiers as a part of app installation?

• Simplest way to use a DatagridView with Linq to SQL

  - by Martín Marconcini

  Hi, I have never used datagrids and such, but today I came across a simple problem and decided to "databind" stuff to finish this faster, however I've found that it doesn't work as I was expecting. I though that by doing something as simple as: var q = from cust in dc.Customers where cust.FirstName == someString select cust; var list = new BindingList<Customer>(q.ToList()); return list; Then using that list in a DataGridView1.DataSource was all that I needed, however, no matter how much I google, I can't find a decent example on how to populate (for add/edit/modify) the results of a single table query into a DataGridView1. Most samples talk about ASP.NET which I lack, this is WinForms. Any ideas? I've came across other posts and the GetNewBindingList, but that doesn't seem to change much. What am I missing (must be obvious)? Thanks in advance. Martin.

• JDBC ResultSet.getString Before/After Start/End of ResultSet Exception

  - by Geowil

  I have done a lot of searching about this topic through Google but I have yet to find someone using getString() in the way that I am using it so I have not been able to fix this issue in the normal ways that are suggested. What I am trying to do is to obtain all of the information from the database and then use it to populate a table model within the program. I do so by obtaining the data with getString and place it into a String[] object: try { while (rSet.next()) { String row[] = {rSet.getString("DonorName"),rSet.getString("DonorCharity"),((String)rSet.getString("DonationAmount"))}; model.addRow(row); } } However I am always getting a dialog error message stating those error messages in the title: Exception: Before start of result set Exception: After end of result set The data is still added and everything works correctly but it is just annoying to have to dismiss those message windows. Does anyone have some suggestions?

• Zend without Database

  - by dbemerlin

  Hi, i googled for an hour now but maybe my Google-Fu is just too weak, i couldn't find a solution. I want to create an application that queries a service via JSON requests (all data and backend/business logic is stored in the service). With plain PHP it's simple enough since i just make a curl request, json_decode the result and get what i need. This already works quite well. A request might look like this: Call http://service-host/userlist with body: {"logintoken": "123456-1234-5678-901234"} Get Result: { "status": "Ok", "userlist":[ {"name": "foo", "id": 1}, {"name": "bar", "id": 2} ] } Now we want to get that into the Zend Framework since it's a hobby project and we want to learn about Zend. The problem is that all information i could find use a Database. Is there even a way to create a Zend Project that does not use a Database? And how can i write a model that represents the actions instead of objects and object-relations?

• Is there a name for the technique of using base-2 numbers to encode a list of unique options?

  - by Lunatik

  Apologies for the rather vague nature of this question, I've never been taught programming and Google is rather useless to a self-help guy like me in this case as the key words are pretty ambiguous. I am writing a couple of functions that encode and decode a list of options into a Long so they can easily be passed around the application, you know this kind of thing: 1 - Apple 2 - Orange 4 - Banana 8 - Plum etc. In this case the number 11 would represent Apple, Orange & Plum. I've got it working but I see this used all the time so assume there is a common name for the technique, and no doubt all sorts of best practice and clever algorithms that are at the moment just out of my reach.

• Using Qt's XML library for simple operation

  - by David Powers

  I basically want to use the XML parser from Qt in my existing project. I have only used Qt once before, and that was with Qt Designer, and I am not having much luck finding anything on Google about how to just use the XML library. I have downloaded a web page that has one large list, and I want to parse it and add each list item to a c++ list. I found this sample code on Ubuntu forums... http://www.uluga.ubuntuforums.org/showpost.php?p=9112973&postcount=6 I want to use that except I need to know what exactly I need to add to the project to get access to it. One other small question is QDomDocument seems to be for files (makes sense) but I have the XML in a string. What part of the XML library works for contents of a string?

• .NET & ASP vs PHP

  - by gargantaun

  Earlier today I asked wether it would be a good idea to develop websites using C#. Most of the answers pointed towards .NET and ASP. Currently I develop with PHP. I've dabbled with Python and RoR but I always come back to PHP. This is the first time I've looked at .NET and ASP. A bucket load of Google searches later I'm not really seeing much support for ASP online but then it all seems a bit Biased towards PHP/Apache/MySQL. It looks like there's a fair amount of .NET and ASP folk around here so I figured it's worth a shot asking for their input in attempt to try and address the balance in my own head. It can't all be bad. What advantages are there to .NET and ASP over PHP?

• (2006, 'MySQL server has gone away') in WSGI django

  - by Stefano Borini

  I have a MySQL gone away with Django under WSGI. I found entries for this problem on stackoverflow, but nothing with Django specifically. Google does not help, except for workarounds (like polling the website every once in a while, or increasing the database timeout). Nothing definitive. Technically, Django and/or MySQLdb (I'm using the latest 1.2.3c1) should attempt a reconnect if the server hanged the connection, but this does not happen. How can I solve this issue without workarounds ?

• Is there a way to hide the Android Device Chooser?

  - by janfsd

  Whenever I run my app I get the Android Device Chooser dialog: This is happening because I am using the Google APIs for 1.6 and trying to run the application on my Nexus one. Is there any way to make this automatically, or to not check the compatibility? Sometimes when I make a modification and quickly after I save and run the application, Eclipse will build the project and the Android Device Chooser dialog will show briefly and disappear and the app won't run. I have to click run again for it to work. Any workarounds?

• Any "trick" to use some keys to launch an application?

  - by Profete162

  Hello, I am currently developing an free application (TaskOS ) that allow users to have multitasking and switch easily between applications on their mobile ( like alt+tab in Windows ) That work pretty well and user can launch my application by a long press on the "search" button" by adding this line in the manifest: <action android:name="android.intent.action.SEARCH_LONG_PRESS" /> I also succeed to allow to the users to Use the camera button ( they can of course disable that in application settings) and the way to do that is slighlty different: <receiver android:name=".CameraPressed"> <intent-filter android:priority="10000"> <action android:name="android.intent.action.CAMERA_BUTTON"/> </intent-filter> I am now wondering if there are other ways to launch easily my task switcher? ( long press on Home key, long press on trackball, or any other idea.) Reading the Google documentation does not help me a lot. Any other idea/suggestion would be warmly welcome. Christophe

• htaccess, remove text from url

  - by Keiron Lowe

  Here is the email from the client explaining what he is trying to do, we have spent hours trying to sort out this problem but cannot find a solution that works. I am trying to correct a problem with my blog and google “not found” URLs. I thought it might be very simple to correct (!ha!) This is my line of code; RewriteCond %{THE_REQUEST} ^www.uk-domestic-cleaning.com/wpblog/tag/?(.*)/HomeMaid%20Domestic%20Cleaning$ RewriteRule ^wpblog\/tag\/?(.*)\/HomeMaid%20Domestic%20Cleaning$ "http\:\/\/www\.uk\-domestic\-cleaning\.com\/wpblog\/tag\/$1" [R=301,L] What I am trying to do is any request to */wplog/tag/ “anything here”/HomeMaid Domestic Cleaning To strip the “HomeMaid Domestic Cleaning” bit off the end, but leave the rest of the request intact, which will then be a valid request. Any idea's guys?

• MATLAB - Delete elements of binary files without loading entire file

  - by Doresoom

  This may be a stupid question, but Google and MATLAB documentation have failed me. I have a rather large binary file (10 GB) that I need to open and delete the last forty million bytes or so. Is there a way to do this without reading the entire file to memory in chunks and printing it out to a new file? It took 6 hours to generate the file, so I'm cringing at the thought of re-reading the whole thing. EDIT: The file is 14,440,000,000 bytes in size. I need to chop it to 14,400,000,000.

• Solr date field tdate vs date?

  - by user550178

  So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)... Also checked: http://www.lucidimagination.com/blog/2009/05/13/exploring-lucene-and-solrs-trierange-capabilities/ http://web.archiveorange.com/archive/v/AAfXfqRYyLnDFtskmLRi

• Seaching for an element in a circular sorted array

  - by guirgis

  I wanted to share this with you, i had this problem in a google interview. we want to search for a given element in a circular sorted array in complexity not greater than O(Log n). ex: search for 13 in {5,9,13,1,3}. My idea was to convert the circular array into a regular sorted array then do a binary search on the resulting array, but my problem was the algorithm i came up was stupid that it takes O(n) in the worst case: for(i = 1; i < a.length; i++){ if (a[i] < a[i-1]){ minIndex = i; break; } } then the corresponding index of ith element will be determined from the following relation: (i + minInex - 1) % a.length it is clear that my conversion (from circular to regular) algorithm may take O(n), so we need a better one, any suggestions?

• Is it possible to use re2 from Python?

  - by flow

  i just discovered http://code.google.com/p/re2, a promising library that uses a long-neglected way (Thompson NFA) to implement a regular expression engine that can be orders of magnitudes faster than the available engines of awk, Perl, or Python. so i downloaded the code and did the usual sudo make install thing. however, that action had seemingly done little more than adding /usr/local/include/re2/re2.h to my system. there seemed to be some `*.a file in addition, but then what is it with this *.a extension? i would like to use re2 from Python (preferrably Python 3.1) and was excited to see files like make_unicode_groups.py in the distro (maybe just used during the build process?). those however were not deployed on my machine. how can i use re2 from Python?

• 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.

• PHP script for creating calendar table or jquery complete solution required

  - by finn_meister

  Ok so this is what I want to make: http://i44.tinypic.com/eiwphl.jpg red = booked green = available I have data in mysql in the format of: property_id, booked_from, booked_until . Before I start trying to create the correct loops etc to create and style the table, i thought i best ask if there are already good jquery plugins / php classes create this visual interface and uncluttered enough to allow me to add a select date range method (like Google Analytics)? I'm looking for something to create a basic calendar table on a loop, which i can then style and add jquery features. Though worth asking if there's a complete package that already does what i plan on making?!! (jquery ui's date-picker doesn't look powerful enough / easy enough to modify)

• How can i determine the version of the Windows SDK installed on my computer?

  - by NuclearCheese781

  Hello everyone :) I've very recently decided to teach myself c++ and win32 programming after learning vb.net, and i've got a very simple question: How can I determine what version of the Windows SDK is installed on my computer? I'm asking so I can install the latest version if it isn't installed allready, before i start playing around with c++. I'm using Microsoft Visual Studio 2008 SP1 as my IDE. (I spent 10 minutes using Google to search for an answer, but I couldn't find one) If anyone could help me, it would be very much appreciated. Matt.
