  • Enum : get the keys list

    - by Damien MATHIEU
    Hello, I'm not a java developer. But I'm currently taking a look at Android applications development so I'm doing a bit of nostalgy, doing some java again after not touching it for three years. I'm looking forward using the "google-api-translate-java" library. In which there is a Language class. It's an enum allowing to provide the language name and to get it's value for Google Translate. I can easily get all the values with : for (Language l : values()) { // Here I loop on one value } But what I'd want to get is a list of all the keys names (FRENCH, ENGLISH, ...). Is there something like a "keys()" method that'd allow me to loop through all the enum's keys ?

  • Best keyboards for emacs?

    - by catphive
    For emacs users out there, what are your recommended keyboards? Bonus points for keyboards that: Have no capslock key. Instead, a control key in that position. Alt keys that are closer to the center, and easier to use with meta key combos. I find alt keys too far to the left to be a bit awkward to hit with my thumb in some key combos. Help ergonomically with emacs in other ways. I'm not a huge fan of model M style high and clacky keys. I instead prefer laptop style flat keys; however, I'm not disqualifying either category.

  • Design patter for extending Android's activities?

    - by Carl
    While programming on Android, I end up writing a parent activity which is extended by several others. A bit like ListActivity. My parent activity extends Activity. if I intend to use a Map or a List, I can't use my parent activity as superclass - the child activity can only extend one activity obviously. As such I end up writing my parent activities with the same logic for Activity, ListActivity, MapActivity and so forth. What am I looking for is some sort of trait functionality/design pattern which would help in this case. Any suggestions?

  • result set using two different views (from an if statement)

    - by mailman1979
    Hi All, I have a bit of code that works with a result set called "result" (original I know) but depending on the incoming variable I'd like to fire the specific query depending. I have the below in an if statement but that just makes the "result" recordset gets those nasty red lines and it doesn't work. I'm sure this is easy to work out. if (area == "dashboard") { IQueryable<ViewGetNavigationMainItem> result = (from m in _entities.ViewGetNavigationMainItems where m.area.Trim() == area.Trim() where m.state == "Online" where m.parentID == parentID orderby m.sequence ascending select m); } else { //Get the Content Items IQueryable<ViewGetNavigationContentItem> result = (from m in _entities.ViewGetNavigationContentItems where m.navID == navID where m.parentID == parentID orderby m.contentOrder ascending select m); } maxRecords = result.Count(); foreach (var item in result) { etc etc etc

  • Django Forms save_m2m

    - by John
    Hi I have a model which has 2 many to many fields in it. one is a standard m2m field which does not use any through tables whereas the other is a bit more complecated and has a through table. I am using the Django forms.modelform to display and save the forms. The code I have to save the form is if form.is_valid(): f = form.save(commit=False) f.modified_by = request.user f.save() form.save_m2m() When i try to save the form I get the following error: Cannot set values on a ManyToManyField which specifies an intermediary model. I know this is happening when I do the form.save_m2m() because of the through table. What I'd liek to do is tell Django to ignore the m2m field with the through table but still save the m2m field without the through table. I can then go on to manually save the data for the through table field. Thanks

  • In .NET, How to obtain the target of a symbolic link (or Reparse Point)?

    - by Cheeso
    In .NET, I think I can determine if a file is a symbolic link by calling System.IO.File.GetAttributes(), and checking for the ReparsePoint bit. like so: var a = System.IO.File.GetAttributes(fileName); if ((a & FileAttributes.ReparsePoint) != 0) { // it's a symlink } How can I obtain the target of the symbolic link, in this case? ps: I know how to create a symbolic link. It requires P/Invoke: [Interop.DllImport("kernel32.dll", EntryPoint="CreateSymbolicLinkW", CharSet=Interop.CharSet.Unicode)] public static extern int CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, int dwFlags);

  • store in a variable only the first or only the second class of an element

    - by shecky
    I'm using this bit of jQ to add a class to two different elements based on the class of another (parent/grandparent, etc) element: $(document).ready(function(){ var containerClass = $('#main-content').attr('class'); $('#nav-primary li#'+containerClass).addClass('active'); $('#aux-left div[id$='+containerClass+']').addClass('active'); }); Brilliant, but I have two problems with it: First, when there's no class at all in <div id="main-content">, the 'active' class is added to all the #nav-primary LIs, and also to all the #aux-left DIVs; how can I modify this so that in the absence of any class on #main-content, do nothing? Second, how can I target only the first or second of multiple classes to store in the 'containerClass' variable, e.g., <div id="main-content" class="apples bananas">? Very much appreciated! svs

  • jquery ui-effects-wrapper causing havoc

    - by vondip
    Hi all, I am using jquery-ui and at some point I use the show and hide functions quite heavily to animate changing images coming in and out. From some reason, after a few tries all of a sudden the controls on my page stop responding to clicks. After a bit of poking arround using firebug I discovered my page is filled with div's of the class ui-effects-wrapper. I have no idea why this happens or how to stop it. If I remove these divs I can no longer see the images I've been animating. Any ideas?

  • SQL Database dilemma : Optimize for Querying or Writing?

    - by Harry
    I'm working on a personal project (Search engine) and have a bit of a dilemma. At the moment it is optimized for writing data to the search index and significantly slow for search queries. The DTA (Database Engine Tuning Adviser) recommends adding a couple of Indexed views inorder to speed up search queries. But this is to the detriment of writing new data to the DB. It seems I can't have one without the other! This is obviously not a new problem. What is a good strategy for this issue?

  • File encodings with ruby

    - by pablorc
    Hi, I'm having a bit problems with file encodings. I'm receiving a url-encoded string like "sometext%C3%B3+more+%26+andmore", unescape it, process the data, and save it with windows-1252 encoding. The conversions are these: irb(main) >> value => "sometext%C3%B3+more+%26+andmore" irb(main) >> CGI::unescape(value) => "sometext\303\263 more & andmore" irb(main) >> #Some code and saved into a file using open(filename, "w:WINDOWS-1252") irb(main) >> # result in the file: => sometextA³ more & andmore And the result should be sometextó more & andmore

  • Is it a good idea to apply some basic macros to simplify code in a large project?

    - by DoctorT
    I've been working on a foundational c++ library for some time now, and there are a variety of ideas I've had that could really simplify the code writing and managing process. One of these is the concept of introducing some macros to help simplify statements that appear very often, but are a bit more complicated than should be necessary. For example, I've come up with this basic macro to simplify the most common type of for loop: #define loop(v,n) for(unsigned long v=0; v<n; ++v) This would enable you to replace those clunky for loops you see so much of: for (int i = 0, i < max_things; i++) With something much easier to write, and even slightly more efficient: loop (i, max_things) Is it a good idea to use conventions like this? Are there any problems you might run into with different types of compilers? Would it just be too confusing for someone unfamiliar with the macro(s)?

  • What is the most elegant way to deal with sourced files that themselves source (relative) source fil

    - by René Nyffenegger
    I am editing a file like /path/to/file.txt with vim, hence the current directory is /path/to. Now, I have a directory /other/path/to/vim/files that contains sourceA.vim. Also, there is a sourceB.vim file in /other/path/to/vim/files/lib/sourceB.vim In sourceA.vim, I want to source sourceB.vim, so I put a so lib/sourceB.vim into it. Now, in my file.txt, I do a :so /other/path/to/vim/files/sourceA.vim which fails, because the sourcing system is obviously not prepared for relative path names along with sourcing from another directory. In order to fix this, I put a execute "so " . expand("<sfile>:p:h") . "/lib/sourceB.vim" into sourceA.vim which does what I want. However, I find the solution a bit clumsy and was wondering if there is a more elegant solution to it. I cannot put the sourceA.vim nor sourceB.vim into vim's plugin folder.

  • memcpy() safety on adjacent memory regions

    - by JaredC
    I recently asked a question on using volatile and was directed to read some very informative articles from Intel and others discussing memory barriers and their uses. After reading these articles I have become quite paranoid though. I have a 64-bit machine. Is it safe to memcpy into adjacent, non-overlapping regions of memory from multiple threads? For example, say I have a buffer: char buff[10]; Is it always safe for one thread to memcpy into the first 5 bytes while a second thread copies into the last 5 bytes? My gut reaction (and some simple tests) indicate that this is completely safe, but I have been unable to find documentation anywhere that can completely convince me.

  • How to generate distinct random numbers per distinct threads in .NET?

    - by mark
    Dear ladies and sirs. I have to generate 19 bit random numbers. However, there is a constraint - two threads may not generate the same random number when running certain code. The simplest solution is lock the entire code. However, I would like to know if there is a non locking solution. I thought, I can incorporate ManagedThreadId within the produced random numbers, but the ManagedThreadId documentation on the Internet mentions that it may span the whole Int32 range. Unmanaged thread id seems to be limited to 11 bits, still this leaves me with just 8 truly random bits. Are there any other ways? Somehow to utilize the Thread Local Storage, may be? Thanks.

  • How do I read UTF-8 characters via a pointer?

    - by Jen
    Suppose I have UTF-8 content stored in memory, how do I read the characters using a pointer? I presume I need to watch for the 8th bit indicating a multi-byte character, but how exactly do I turn the sequence into a valid Unicode character? Also, is wchar_t the proper type to store a single Unicode character? This is what I have in mind: wchar_t readNextChar (char** p) { char ch = *p++; if (ch & 128) { // This is a multi-byte character, what do I do now? // char chNext = *p++; // ... but how do I assemble the Unicode character? ... } ... }

  • Applying transformations to NSBitmapImageRep

    - by Adam
    So ... I have an image loaded into an NSBitmapImageRep object, so I am able to examine the contents of specific pixels via a two dimensional array. Now I want to apply a couple of "transformations" to the image, in preparation for some additional processing. If I was manipulating the image manually, in Photoshop, I would: Rotate the image Crop a portion of it and discard the rest Apply a "threshold" transformation (which essentially converts the image to black and white, based on the threshold value I provide) Resample the image to shrink it down a bit (which, although losing some image quality, will speed up the subsequent processing) (not necessarily in that order) Are there objective C methods available to facilitate these specific image manipulations, with the data in the NSBitmapImageRep object? If so, can someone point me to some good examples?

  • Stretch image to fill div, but not skew

    - by z0mbieParade
    I'm trying to make an image stretch to fit inside a div. However I want it to overflow so that the entire div is filled. The div resizes with the page. I want an effect similar to the jQuery bgstretcher plugin (http://www.ajaxblender.com/bgstretcher-2-jquery-stretch-background-plugin-updated.html) , but I cannot use that plugin because I'm already using it for the background image on the page, and it seems to not work when you try and activate multiple instances of it. So what I'm asking is for some sort of simple jQuery function that resizes an image to completely fill a div with overflow hidden, so that there are no gaps, but without skewing the image. Edit: http://jsfiddle.net/R7UCZ/ That's sort of what I'm after, but I want the image to fill the entire div without skewing. If the image goes out of the div a bit, that's fine, but I need it to resize with the div, which resizes with the page, both height and width.

  • Performing Inner Join for Multiple Columns in the Same Table

    - by frankiefrank
    I have a scenario which I'm a bit stuck on. Let's say I have a survey about colors, and I have one table for the color data, and another for people's answers. tbColors color_code , color_name 1 , 'blue' 2 , 'green' 3 , 'yellow' 4 , 'red' tbAnswers answer_id , favorite_color , least_favorite_color , color_im_allergic_to 1 , 1 , 2 3 2 , 3 , 1 4 3 , 1 , 1 2 4 , 2 , 3 4 For display I want to write a SELECT that presents the answers table but using the color_name column from tbColors. I understand the "most stupid" way to do it naming tbColors three times in the FROM section, using a different alias for each column to replace. How would a non-stupid way look?

  • Repository, Service or Domain object - where does logic belong?

    - by betitall
    Take this simple, contrived example: UserRepository.GetAllUsers(); UserRepository.GetUserById(); Inevitably, I will have more complex "queries", such as: //returns users where active=true, deleted=false, and confirmed = true GetActiveUsers(); I'm having trouble determining where the responsibility of the repository ends. GetActiveUsers() represents a simple "query". Does it belong in the repository? How about something that involves a bit of logic, such as: //activate the user, set the activationCode to "used", etc. ActivateUser(string activationCode);

  • Visual artifacts on UIView rotation with tiled background image.

    - by Halbanonym
    I have an iPad app with a standard UIViewController/UIView setup - all rotations are allowed. The UIView draws some tiled image as background (the tile is 256*256 pixels): - (void)drawRect:(CGRect)rect { [[UIImage imageNamed: @"Background.png"] drawAsPatternInRect: rect]; } When I turn my iPad I can see that during the rotation the image pattern of the original orientation is scaled to fit the new orientation. Then - immediately after the animation is finished - the view redraws its background pattern with the final configuration which is unscaled. The switching from a scaled to an unscaled pattern looks a bit ugly. Is there a way to circumvent (or hide) this strecthing of the background pattern?

  • VIM: Columnvise Increment inside and outside?

    - by hhh
    By outside, I want solutions that does not use Vim's scripting hacks but try to reuse certain basic *ix tools. Inside Vim stuff asks for solutions to get the column-increment with inside stuff such as scripting. 1 1 1 2 1 3 1 ---> 4 1 5 1 6 . . . . Vim has a script that does column-vise icrementing here. It has gathered about 50/50 ups and down, perhaps tasting a bit reinventing-the-wheel. How do you column-increment stuff in Vim without using such script? Then the other question is, how do you column-increment stuff without/outside Vim? Most elegant, reusable and preferrably-small wins the race!

  • Setting up scripts in Amazon EC2 Cloud

    - by racket99
    Hello, I am currently running a few perl and python scripts on a windows pc and would like to port over to the Amazon EC2 servers running 64-bit LINUX. The scripts are basic web scrapers that go to a variety of websites, get data and then save daily as csv files. I would like to install these in the cloud and get them running in an automated way so that they will run without my intervention. Also given that I don't want to lose all the data if the instance crashes, I should also upload the csv files to Amazon S3. Any idea how I can do this? I am not terribly versed in LINUX nor do I know Perl/Python well. What is the best way for me to tackle thi
