• need identical string comparison function in php and java

  - by steelbytes

  I have sorted list of strings that I move between php and java. to be able to bsearch on this data, I need the same comparison function. any idea what string compare functions I can use that will always give the same result in both? eg php's strcmp() vs java's String.compareTo() yes I know I could make my own string compare that does char by char carefully, but I was hoping there's a simple answer. PS, don't care if case sensitive or not, as long as it is consistant.

• Minimalistic PHP template engine with caching but not Smarty?

  - by Pekka

  There are loads of questions for "the right" PHP template engine, but none of them is focused on caching. Does anybody know a lightweight, high-quality, PHP 5 based template engine that does the following out of the box: Low-level templating functions (Replacements, loops, and filtering, maybe conditionals) Caching of the parsed results with the possibility to set an individual TTL per item, and of course to force a reload programmatically Extremely easy usage (like Smarty's) Modest in polluting the namespace (the ideal solution would be one class to interact with from the outside application) But not Smarty. I have nothing against, and often use, Smarty, but I am looking for something a bit simpler and leaner. I took a look at Fabien Potencier's Twig that looks very nice and compiles templates into PHP code, but it doesn't do any actual caching beyond that. I need and want a template engine, as I need to completely separate code and presentation in a way that a HTML designer can understand later on, so please no fundamental discussions about whether template engines in PHP make sense. Those discussions are important, but they already exist on SO.

• mysql birthday reminder, leap year

  - by moodh

  Hi, I'm trying to sort out a result set that gives the 5 closest users sorted by upcoming birthday. This works perfectly until leap years comes into play. For example: May 15th - 96 days left May 15th - 97 days left The top result is a birth at 1987 and the lower is from 1988. u_birth is stored as yyyy-mm-dd. Is there a simple way to sort this problem without having to rewrite the entire query? SELECT u_birth, IF( DAYOFYEAR( u_birth ) >= DAYOFYEAR( NOW() ), DAYOFYEAR( u_birth ) - DAYOFYEAR( NOW() ), DAYOFYEAR( u_birth ) - DAYOFYEAR( NOW() ) + DAYOFYEAR( CONCAT( YEAR( NOW() ), '-12-31' ) ) ) AS distance FROM (blog_users) WHERE `s_agehide` = 0 ORDER BY distance ASC LIMIT 5 This query is taken and modified from the mysql manual: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#c7489

• Marshal a C++ class to C#

  - by Adam Haile

  I need to access code in a native C++ DLL in some C# code but am having issues figuring out the marshaling. I've done this before with code that was straight C, but seem to have found that it's not directly possible with C++ classes. Made even more complicated by the fact that many of the classes contain virtual or inline functions. I even tried passing the headers through the PInvoke Interop Assistant, but it would choke on just about everything and not really no what to do... I'm guessing because it's not really supported. So how, if at all possible, can you use a native C++ class DLL from .NET code. If I have to use some intermediary (CLR C++?) that's fine.

• How Do I Convert text to a WAV file With Inaudible Waveform?

  - by Scott

  I am trying to create an audio watermarking system. I figure the best solution is to create an audio file (WAV) based on a unique string of text and then combine this with the original wav. The part that makes this tricky (for me anyway) is: How do I convert the text string to a wav? How do I ensure that the resulting WAV form is inaudible (or at least barely noticeable to the listener). I would prefer this be done server side (via PHP, etc) but if the processing load isn't too much then would be ok with something in Flash or Javascript. I'd be willing to pay someone to create me a workable solution (complete source code that functions as described). Thanks, Scott!

• How to deal with many to many relationships with NSFetchedResultsController?

  - by Phil Yates

  OK so I have two entities in my data model (let's say entityA and entityB), both of these entities have a to-many relationship to each other. I have setup a NSFetchedResultsController to fetch a bunch of entityA. Now I'm trying to have the section names for the tableview be the title of entityB. sectionNameKeyPath:@"entityB.title" Now this causes a problem, where by the section name returned from that relationship appears to be ({title1}) or ({title1,title2...titleN}) obviously depending on how many different entityB's are involved. This doesn't look great in a tableview and doesn't group the objects as I would like. What I would like is a section per entityB title with entityA appearing under each section, under multiple sections if necessary. I'm at a loss as how I am supposed to achieve this whether I need to update the predicate to get the entity to appear multiple times or whether I need to update the section and header functions to do some processing as the controller loops through the objects. Any help is appreciated :) Thanks

• Deleting SQLite rows automatically/periodically

  - by anselmophil

  Hi guys! So, i have a application that displays tasks and i created an option in the Settings menu that lets you choose in how many days all (Never, 10 days, 20 days or 30 days) these tasks should be automatically deleted. So when i open up the app there will be a method that will be called and check if theres any tasks to be deleted. I did that to challenge myself, but i'm hitting the wall with my head and i cant come up with something. So here i am in need of help! A little more information: i was trying to do something with java/android code, but from past searches i saw people dealing with it using SQL functions. Is it better? Thanks in advance guys!

• Arrow operator (->) usage in C

  - by Mohit Deshpande

  I am currently learning C by reading a good beginner's book called "Teach Yourself C in 21 Days" (I have already learned Java and C# so I am moving at a much faster pace). I was reading the chapter on pointers and the - (arrow) operator came up without explanation. I think that it is used to call members and functions (like the equivalent of the . (dot) operator, but for pointers instead of members). But I am not entirely sure. Could I please get an explanation and a code sample?

• plist vs static array

  - by morticae

  Generally, I use static arrays and dictionaries for containing lookup tables in my classes. However, with the number of classes creeping quickly into the hundreds, I'm hesitant to continue using this pattern. Even if these static collections are initialized lazily, I've essentially got a bounded memory leak going on as someone uses my app. Most of these are arrays of strings so I can convert strings into NSInteger constants that can be used with switch statements, etc. I could just recreate the array/dictionary on every call, but many of these functions are used heavily and/or in tight loops. So I'm trying to come up with a pattern that is both performant and not persistent. If I store the information in a plist, does the iphoneOS do anything intelligent about caching those when loaded? Do you have another method that might be related?

• UTF-8 xml file shows Gibberish

  - by Adam

  I have a UTF-8 encoded xml file, which was exported from a Wordpress MySQL database. While the file is saved as UTF-8, and the encoding is UTF-8, I get gibberish instead of the Hebrew text that is supposed to be in there, which looks like this: ™×•×˜×•×ª How can I find the original encoding or charset and convert the text into proper Hebrew? PHP's mb_detect_encoding($str); returns UTF-8 Tried all sorts of php encoding functions, with different settings and input/output charsets, but they all just print different looking gibberish blocks, like: ÃâÃËÃâ¢Ãâ¢ÃËà and ?? ××©×ž× ...Any Ideas how to go about this?

• XmlSerializer Performance Issue when Specifying XmlRootAttribute

  - by Dougc

  I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

• .delegate equivalent of an existing .live method in jQuery 1.4.2

  - by kim3er

  I have an event handler bound to the hover event using the .live method, which is below: $(".nav li").hover(function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); It is important to note, that I require both functions within the handler to ensure synchronisation. Is it possible to rewrite the function using .delegate, as the following does not work? $(".nav").delegate("li", "hover", function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); Rich

• JQuery never reaches success or fail on aspx returning json.

  - by David

  Basicaly I have my aspx page doing <% Response.Clear(); Response.Write("{\"Success\": \"true\" }"); Response.End(); %> My JQuery code is function DoSubmit(r) { if (r == null || r.length == 0 || formdata == null || formdata.length == 0) return; for (i = 0; i < formdata.length; i++) { var fd = formdata[i]; r[fd.Name] = fd.Value; } r["ModSeq"] = tblDef.ModSeq; jQuery.ajax({ url: "NashcoUpdate.aspx" , succsess: doRow , error: DoSubmitError , complete: DoSubmitComplete , dataType: "json" , cache: false , data: r , type: "post" }) } When I call the DoSubmit() function every thing works but the doRow or DoSubmitError functions never get called only the DoSubmitComplete function. When I look at the response text in teh DoSubmitComple function it is {"Success": "true" } Every JSON tester I have tried says that this is valied JSON. What am I doing wrong here?

• Clone a div that contains "customized" jQueryUI datePicker

  - by Enrique

  I have a div that contains 3 fields You can see the image here http://imgur.com/A3tbd.jpg I'm cloning this div with this plugin http://sroucheray.org/blog/demos/jquery-dynamic-form/ My problems are: It doesn't clone correctly datePicker. I'm using validate form plugin, but I guess this plugin is not prepared to validate cloned elements Is there any easy code, other plugin or some functions I should use for doing this sequence? Verify user has filled the 3 fields of the actual div If so, clone the div and create a new set of 3 fields. Also, clone datePicker correctly If user clicks the delete button, erase last div (last 3 fields) When form submitted, post all fields correctly Thanks,

• Cross platform unicode path handling

  - by Matt Joiner

  I'm using boost::filesystem for cross-platform path manipulation, but this breaks down when calls need to be made down into interfaces I don't control that won't accept UTF-8. For example when using the Windows API, I need to convert to UTF-16, and then call the wide-string version of whatever function I was about to call, and then convert any output back to UTF-8. While the wpath, and other w* forms of many of the boost::filesystem functions help keep sanity, are there any suggestions for how best to handle this conversion to wide-string forms where needed, while maintaining consistency in my own code?

• Iterating Oracle collections of objects with out exploding them

  - by Scott Bailey

  I'm using Oracle object data types to represent a timespan or period. And I've got to do a bunch of operations that involve working with collections of periods. Iterating over collections in SQL is significantly faster than in PL/SQL. CREATE TYPE PERIOD AS OBJECT ( beginning DATE, ending DATE, ... some member functions...); CREATE TYPE PERIOD_TABLE AS TABLE OF PERIOD; -- sample usage SELECT <<period object>>.contains(period2) FROM TABLE(period_table1) t The problem is that the TABLE() function explodes the objects into scalar values, and I really need the objects instead. I could use the scalar values to recreate the objects but this would incur the overhead of re-instantiating the objects. And the period is designed to be subclassed so there would be additional difficulty trying to figure out what to initialize it as. Is there another way to do this that doesn't destroy my objects?

• C/C++ Allegro program causes Windows 7 to switch to Aero Basic

  - by Matt H

  Hi SO, I'm just trying out the allegro library, and here is the code which I've got so far: #include <allegro.h> int main(int argc, char *argv[]) { allegro_init(); // initialize the allegro libraries install_keyboard(); // initialize keyboard functions set_color_depth(16); // set the color depth set_gfx_mode(GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0); // set up 640*480px window BITMAP *pic = NULL; pic = load_bitmap("C:/picture.bmp", NULL); // load the picture blit(pic, screen, 0, 0, 0, 0, 1000, 1000); readkey(); destroy_bitmap(pic); return 0; } END_OF_MAIN() It works fine, but when I run it, while the program's window is open, Windows 7 changes the theme from Aero to Aero basic. If you aren't sure what I mean, this pops up (I got this from Google, which is why it says Vista rather than Windows 7): 1) Why? 2) How can I ensure that this doesn't happen?

• How should I do custom sort in Python 3?

  - by S.Mark

  In Python 2.x, I could pass custom function to sorted and .sort functions >>> x=['kar','htar','har','ar'] >>> >>> sorted(x) ['ar', 'har', 'htar', 'kar'] >>> >>> sorted(x,cmp=customsort) ['kar', 'htar', 'har', 'ar'] Because, in My language, consonents are comes with this order "k","kh",....,"ht",..."h",...,"a" But In Python 3.x, looks like I could not pass cmp keyword >>> sorted(x,cmp=customsort) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'cmp' is an invalid keyword argument for this function Is there any alternatives or should I write my own sorted function too?

• How to use Zend Cache with SimpleXML objects?

  - by Jeremy Hicks

  I'm trying to cache the user timeline of a Twitter feed using Zend_Service_Twitter which returns its results as a SimpleXML object. Unfortunately the regular serialize functions (which Zend Cache uses) don't play nice with SimpleXMl objects. I found this http://www.mail-archive.com/[email protected]/msg18133.html. So it looks like I'll need to create some kind of custom frontend for Zend Cache to be able to change the serialize function used. Anybody ever done this already or can point me where to look to start?

• Why does gcc add symbols to non-debug build?

  - by Matt Holgate

  When I do a release build with gcc (i.e. I do not specify -g), I still seem to end up with symbols in the binary, and have to use strip to remove them. In fact, I can still breakpoint functions and get backtraces in gdb (albeit without line numbers). This surprised me - can anyone explain why this happens? e.g. #include <stdio.h> static void blah(void) { printf("hello world\n"); } int main(int argc, char *argv[]) { blah(); return 0; } gcc -o foo foo.c nm foo | grep blah: 08048374 t blah

• Cross-reference between delphi records

  - by Paul-Jan

  Let's say I have a record TQuaternion and a record TVector. Quaternions have some methods with TVector parameters. On the other hand, TVector supports some operations that have TQuaternion parameters. Knowing that Delphi (Win32) does not allow for forward record declarations, how do I solve this elegantly? Using classes is not really an option here, because I really want to use operator overloading for this rare case where it actually makes good sense. For now I simply moved these particular methods out of the records and into separate functions, the good old-fashioned way. Better suggestions are most welcome.

• Getting a sorted distinct list from mySQL

  - by Stomped

  Goal I'l like to get a list of unique FID's ordered by the the one which has most recently been changed. In this sample table it should return FIDs in the order of 150, 194, 122 Example Data ID FID changeDate ---------------------------------------------- 1 194 2010-04-01 2 122 2010-04-02 3 194 2010-04-03 4 150 2010-04-04 My Attempt I thought distinct and order by would do the trick. I initially tried: SELECT distinct `FID` FROM `tblHistory` WHERE 1 ORDER BY changeDate desc # Returns 150, 122, 194 using GROUP BY has the same result. I'm just barely a SQL amateur, and I'm a bit hung up. What seems to be happening is the aggregating functions find the first occurrence of each and then perform the sort. Is there a way I can get the result I want straight from mySQL or do I have to grab all the data and then sort it in the PHP?

  Hello, I have a Java application and I want to implement an Undo/Redo option. the value that I want to stock and that I want to be able to recover is an integer. My Class Model implements the interface StateEditable and I have to redefine the 2 functions restoreState(Hashtable<?, ?> state) and storeState(Hashtable<Object, Object> state) but I don't know what to put on them. It will be really great if somebody can help me to do that.

What I want to do is to have a property in the usercontol to control the orientation So I basicaly have UserControl -- Listbox -- MyPanel And I want a property for the usercontrol that can be set in xaml (of type System.Windows.Controls.Orientation ) that I can bind to from my custom panel (or a different approach if binding isnt the right way to do it) It would be a bonus if that property could show up in the properties window and you could select vertical or horizontal. And a super bonus if I could change the property at design time and have the listbox/
