  • How do I make a third party .jar available to my .jsp page?

    - by Matthew
    I'm just starting to learn JSP (and I'm pretty new to Java in general), and I'd like to use JSON-lib with it. I want to make a page something like this: <%@ page import="net.sf.json.JSONObject"%> <% String json = new JSONObject().put("hello", "world").toString(); out.println(json); %> I downloaded json-lib-2.3-jdk15.jar and put it in the same directory as the .jsp page. But I get this error org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 6 in the generated java file Only a type can be imported. net.sf.json.JSONObject resolves to a package An error occurred at line: 3 in the jsp file: /getCard.jsp JSONObject cannot be resolved to a type 1: <%@ page import="net.sf.json.JSONObject" %> 2: <% 3: String json = new JSONObject().put("hello", "world").toString(); 4: out.println(json); 5: %> 6: How do I make the JSONObject class available to my .jsp page?

  • Caching issue with javascript and asp.net

    - by Ed Woodcock
    Hi guys: I asked a question a while back on here regarding caching data for a calendar/scheduling web app, and got some good responses. However, I have now decided to change my approach and stat caching the data in javascript. I am directly caching the HTML for each day's column in the calendar grid inside the $('body').data() object, which gives very fast page load times (almost unnoticable). However, problems start to arise when the user requests data that is not yet in the cache. This data is created by the server using an ajax call, so it's asynchronous, and takes about 0.2s per week's data. My current approach is simply to block for 0.5s when the user requests information from the server, and cache 4 weeks either side in the inital page load (and 1 extra week per page change request), however I doubt this is the optimal method. Does anyone have a suggestion as to how to improve the situation? To summarise: Each week takes 0.2s to retrieve from the server, asynchronously. Performance must be as close to real-time as possible. (however the data is not needed to be fully real-time: most appointments are added by the user and so we can re-cache after this) Currently 4 weeks are cached on either side of the inial week loaded: this is not enough. to cache 1 year takes ~ 21s, this is too slow for an initial load.

  • Moving inserted container element if possible

    - by doublep
    I'm trying to achieve the following optimization in my container library: when inserting an lvalue-referenced element, copy it to internal storage; but when inserting rvalue-referenced element, move it if supported. The optimization is supposed to be useful e.g. if contained element type is something like std::vector, where moving if possible would give substantial speedup. However, so far I was unable to devise any working scheme for this. My container is quite complicated, so I can't just duplicate insert() code several times: it is large. I want to keep all "real" code in some inner helper, say do_insert() (may be templated) and various insert()-like functions would just call that with different arguments. My best bet code for this (a prototype, of course, without doing anything real): #include <iostream> #include <utility> struct element { element () { }; element (element&&) { std::cerr << "moving\n"; } }; struct container { void insert (const element& value) { do_insert (value); } void insert (element&& value) { do_insert (std::move (value)); } private: template <typename Arg> void do_insert (Arg arg) { element x (arg); } }; int main () { { // Shouldn't move. container c; element x; c.insert (x); } { // Should move. container c; c.insert (element ()); } } However, this doesn't work at least with GCC 4.4 and 4.5: it never prints "moving" on stderr. Or is what I want impossible to achieve and that's why emplace()-like functions exist in the first place?

  • Switching to WPF, the best use of time at Visual Studio Launch 2010

    - by Stewbob
    Yes, this is a programming-related question, if a little indirectly (that's why I marked it Community Wiki right away). For better or worse, I am switching from Winforms to WPF in April. I am also going to be in attendance at the Visual Studio Launch in Las Vegas. I have a real need to get up to speed quickly in WPF, so my question is: What sessions are going to be the best use of my time? I've got some picked out already, but I'm looking for some more advice on how to wade through all the marketing fluff and get some real educational value out of these few days. I have not been to one of these events before, so I don't really know how much is marketing hype, and how much is solid content. A couple of the workshops look interesting (VPR02 and VPS02), but I don't know enough about the actual content of these to justify the extra expense right now. Any thoughts there would be appreciated. And yes, I do have WPF learning planned other than just these few days in Vegas, but since I'm going to be there anyway, I want to learn as much as I can in the time available.

  • How do I make a web interface for a socket server

    - by mgroat
    I've got a socket server running (it's something that's basically like a chat server). Users can telnet into it, but I'd like to make a web interface. This is the first time I've ever done something like this, so I'm not really sure where to start. A few thoughts I've had: Have some server-side Python (or PHP) on my webserver, which accesses the socket server. I think I know enough about sockets to have Python interact with the server, but how do I go about getting the website that the user sees to update in real time? Should I just have the website refresh few seconds? I would prefer to do things this way if I can figure out how. Write a Java applet that interacts with the socket server, and embed the applet in the website. I would have to re-learn a language that I haven't touched in years, but my main goal here is learning -- so that wouldn't be such a bad thing. The main problem I have with this is that it requires end users to have Java installed on their computers, which I'd rather not do. Is one of these two solutions the right way to go? Anybody know where I can find a good tutorial to get started? Edit: There's no real security concerns with exposing the server to the internet.

  • Javascript: How to test JSONP on localhost

    - by hqt
    Here is the way I test JSONP: I run XAMPP, and in folder htdocs I create a javascript folder . I create json1.json file contain some data to process. After that, I run this html file locally, and it will call a function in "other machine" (in this case is localhost) Here is my code : <head> <script> function updateSales(sales) { alert('test jsonp'); // real code here } </script> </head> <body> <h1>JSONP Example</h1> <script src="http://localhost:85/javascript/json1.json?callback=updateSales"></script> </body> But when I run, nothing happen. But if change to other real json on the internet, it will work. It means change line : <script src="http://localhost:85/javascript/json1.json?callback=updateSales"></script> to line: <script src="http://gumball.wickedlysmart.com/?callback=updateSales"></script> It will work smoothly. So, I don't know how to test JSONP by using localhost, please help me. Thanks :)

  • How to calculate this string-dissimilarity function efficiently?

    - by ybungalobill
    Hello, I was looking for a string metric that have the property that moving around large blocks in a string won't affect the distance so much. So "helloworld" is close to "worldhello". Obviously Levenshtein distance and Longest common subsequence don't fulfill this requirement. Using Jaccard distance on the set of n-grams gives good results but has other drawbacks (it's a pseudometric and higher n results in higher penalty for changing single character). [original research] As I thought about it, what I'm looking for is a function f(A,B) such that f(A,B)+1 equals the minimum number of blocks that one have to divide A into (A1 ... An), apply a permutation on the blocks and get B: f("hello", "hello") = 0 f("helloworld", "worldhello") = 1 // hello world -> world hello f("abba", "baba") = 2 // ab b a -> b ab a f("computer", "copmuter") = 3 // co m p uter -> co p m uter This can be extended for A and B that aren't necessarily permutations of each other: any additional character that can't be matched is considered as one additional block. f("computer", "combuter") = 3 // com uter -> com uter, unmatched: p and b. Observing that instead of counting blocks we can count the number of pairs of indices that are taken apart by a permutation, we can write f(A,B) formally as: f(A,B) = min { C(P) | P:|A|?|B|, P is bijective, ?i?dom(P) A[P(i)]=B[P(i)] } C(P) = |A| + |B| - |dom(P)| - |{ i | i,i+1?dom(P) and P(i)+1=P(i+1) }| - 1 The problem is... guess what... ... that I'm not able to calculate this in polynomial time. Can someone suggest a way to do this efficiently? Or perhaps point me to already known metric that exhibits similar properties?

  • Why does my Perl CGI script cause a 500 internal server error?

    - by Nitish
    I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "<HTML>\n"; print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H2>Hello World!</H2> <br /> \n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}<p>" ; } print "</BODY>\n"; print "</HTML>\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

  • How does the PHP IteratorIterator class work?

    - by WilliamMartin
    Try as I might I cannot get my head around what the IteratorIterator class actually does. I understand that classes can implement Traversable so the engine knows it can loop using foreach and I realise that IteratorIterator is supposed to convert anything that is Traversable into an Iterator but I cannot for the life of me understand how. Take for example, the PDOStatement class; how would the standard Iterator methods (next, key, rewind, etc) be implemented to allow iteration over a PDOStatement? Sorry if my question is unclear, I am just struggling to grasp the exact reason for this class and the documentation on it is scant. Thanks, Will Update: Going through the phpt files, I found one test which uses IteratorIterator: <?php $root = simplexml_load_string('<?xml version="1.0"?> <root> <child>Hello</child> <child>World</child> </root> '); foreach (new IteratorIterator($root->child) as $child) { echo $child."\n"; } ?> The expected output is: Hello World I don't really follow how the IteratorIterator construct takes $root-child as an argument and how it manages to iterate over the child elements.

  • node.js beginner tutorials?

    - by TreyK
    Hey all, I'm working on creating my first real node.js http server, and I'm sort of drowning in it. As a good teacher of mine always said, "I'll just shove you in the water for now, and then I'll show you how to swim." Fortunately, she wasn't a swimming instructor, but it's a good analogy nonetheless. I feel like I've jumped into node.js and I've only found a ping pong ball to help, that is to say, most of the tutorials I've read stop shortly after the "Hello World" example and I've mostly been trying to make sense of copied and pasted code (or they assume I have knowledge of lower level HTTP and webserver concepts that have been done for me as an Apache/PHP developer). I have experience in both client-side Javascript and PHP, but node seems to be a beast all of its own. I don't quite have the low-level knowledge that seems necessary for creating a node server, and connect, which seems to be a nice module for simplifying things, seems quite sparsely explained, even in the docs on its Git. Where could I find some tutorials to help me in this situation? TL;DR - Are there any tutorials for node.js that go beyond "Hello World" but don't require much low-level knowledge? Or any tutorials that explain lower-level HTTP and webserver concepts that I would need to effectively create a node HTTP server? Thanks for any help. -Trey

  • How to send an array of complex type in PHP using Soap_Client?

    - by xaguilars
    Hello I want to know how to send this array of complex data to a SOAP server (that uses .NET / IIS). <xs:complexType name="SampleStruct"> <xs:sequence> <xs:element name="title" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> <xs:complexType name="SampleStruct_Array"> <xs:complexContent> <xs:restriction base="soapenc:Array"> <xs:sequence/> <xs:attribute ref="soapenc:arrayType" n1:arrayType="ns1:SampleStruct[]"/> </xs:restriction> </xs:complexContent> </xs:complexType> Would this code be ok? : $data1 = new SampleStruct(); $data1->title="Hello world"; $data1->description="This is a sample description."; $data2 = new SampleStruct(); $data2->title="Hello world 2"; $data2->description="This is a sample description 2."; $client->__soapCall("sampleFunction", array( new SoapParam(new SoapVar(array($data1, $data2) , SOAP_ENC_ARRAY, "SampleStruct_Array", "http://www.w3.org/2001/XMLSchema"), "theSampleFunctionParamName") )); Am I doing it ok? I'm not very familiar with Web services... Thank you

  • Get the equivalent time between "dynamic" time zones

    - by doctore
    I have a table providers that has three columns (containing more columns but not important in this case): starttime, start time in which you can contact him. endtime, final hour in which you can contact him. region_id, region where the provider resides. In USA: California, Texas, etc. In UK: England, Scotland, etc starttime and endtime are time without timezone columns, but, "indirectly", their value has time zone of the region in which the provider resides. For example: starttime | endtime | region_id (time zone of region) | "real" st | "real" et ----------|----------|---------------------------------|-----------|----------- 03:00:00 | 17:00:00 | 1 (EGT => -1) | 02:00:00 | 16:00:00 Often I need to get the list of suppliers whose time range is within the current server time (taking into account the time zone conversion). The problem is that the time zones aren't "constant", ie, they may change during the summer time. However, this change is very specific to the region and not always carried out at the same time: EGT <= EGST, ART <= ARST, etc. The question is: 1. Is it necessary to use a webservice to update every so often the time zones in the regions? Does anyone know of a web service that can serve? 2. Is there a better approach to solve this problem? Thanks in advance. UPDATE I will give an example to clarify what I'm trying to get. In the table providers I found this records: idproviders | starttime | endtime | region_id ------------|-----------|----------|----------- 1 | 03:00:00 | 17:00:00 | 23 (Texas) 2 | 04:00:00 | 18:00:00 | 23 (Texas) If I execute the query in January, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +1 hour Server time = 02:00:00 I should get the following results: idproviders = 1 If I execute the query in June, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +2 hours (their local time has not changed, but their time zone has changed) Server time = 02:00:00 I should get the following results: idproviders = 1 and 2

  • Is there a mechanism to distribute an app with its own JRE?

    - by user179997
    These fine folks are my users: http://www.youtube.com/watch?v=o4MwTvtyrUQ If you don't want to enjoy the video here is the gist: my users can't tell between a file and a folder, between a browser and a web site. I need to create a Java web app (Tomcat or Jetty) and deploy it in as many of their computers, Windows and Mac. The question is: Is there a mechanism to distribute an app with its own JRE? (in the Tcl world there are starpacks and starkits, in the Python world there's py2exe and others, that's the idea). And also, is it legal? I know the VM is open source but I'm not clear about the libraries, and I know about GNU Classpath but I don't know if all the packages are there. I don't want to depend on the installed JRE or on the user having enough privileges to install one. On the Mac I don't want to depend on Apple (I had to switch from Tiger to Snow Leopard just to have Java 1.6, I can't put my users in that position) Any info greatly appreciated. Thanks! jb edit: I'm wondering if I can just paste the JRE folder under my app folder. Is that allowed?

  • PHP Object References in Frameworks

    - by bigstylee
    Before I dive into the disscusion part a quick question; Is there a method to determine if a variable is a reference to another variable/object? For example $foo = 'Hello World'; $bar = &$foo; echo (is_reference($bar) ? 'Is reference' : 'Is orginal'; I have been using PHP5 for a few years now (personal use only) and I would say I am moderately reversed on the topic of Object Orientated implementation. However the concept of Model View Controller Framework is fairly new to me. I have looked a number of tutorials and looked at some of the open source frameworks (mainly CodeIgnitor) to get a better understanding how everything fits together. I am starting to appreciate the real benefits of using this type of structure. I am used to implementing object referencing in the following technique. class Foo{ public $var = 'Hello World!'; } class Bar{ public function __construct(){ global $Foo; echo $Foo->var; } } $Foo = new Foo; $Bar = new Bar; I was surprised to see that CodeIgnitor and Yii pass referencs of objects and can be accessed via the following method: $this->load->view('argument') The immediate advantage I can see is a lot less code and more user friendly. But I do wonder if it is more efficient as these frameworks are presumably optimised? Or simply to make the code more user friendly? This was an interesting article Do not use PHP references.

  • Test if string is URL encoded in PHP

    - by Psytronic
    Hey guys, I've looked through the PHP Docs and can't see anything to do with this, so how can I test if a string is URL encoded? Is it better to search the string for characters which would be encoded, which aren't, and if any exist then its not encoded, or use something like this which I've made function is_urlEncoded($string){ $test_string = $string; while(urldecode($test_string) != $test_string){ $test_string = urldecode($test_string); } return (urlencode($test_string) == $string)?True:False; } $t = "Hello World how are you?"; if(is_urlEncoded($sreq)){ print "Was Encoded.\n"; }else{ print "Not Encoded.\n"; print "Should be ".urlencode($sreq)."\n"; } Which works, however not in instances where this might occur $t = "Hello%2BWorld%2B%253E%2Bhow%2Bare%2Byou%253F"; I.e. where the string has been doubly encoded, or maybe this string $t = "Hello+World%2B%253E%2Bhow%2Bare%2Byou%253F"; I.e. where most has been doubly encoded, except for one space. (Yes I don't know when this string would ever occur, but you never know)

  • Opa app does not load in Internet Explorer when compiled with Opa 1.1.1

    - by Marcin Skórzewski
    I did a minor update to the already working application and then had problems using new version of Opa compiler. First problem - runtime exception Since the original deployment Opa 1.1.1 has been released and it resulted in error: events.js:72 throw er; // Unhandled 'error' event ^ Error: listen EADDRINUSE at errnoException (net.js:901:11) at Server._listen2 (net.js:1039:14) at listen (net.js:1061:10) at Server.listen (net.js:1127:5) at global.BslNet_Http_server_init_server (/opt/mlstate/lib/opa/stdlib/server.opp/serverNodeJsPackage.js:223:1405) at global.BslNet_Http_server_init_server_cps (/opt/mlstate/lib/opa/stdlib/server.opp/serverNodeJsPackage.js:226:15) at __v1_bslnet_http_server_init_server_cps_b970f080 (/opt/mlstate/lib/opa/stdlib/stdlib.qmljs/stdlib.core.web.server.opx/main.js:1:175) at /opt/mlstate/lib/opa/stdlib/stdlib.qmljs/stdlib.core.web.server.opx/main.js:440:106 at global.execute_ (/opt/mlstate/lib/opa/static/opa-js-runtime-cps/main.js:19:49) at /opt/mlstate/lib/opa/static/opa-js-runtime-cps/main.js:17:78 I decided to build Opa from sources and it helped, but another problem occurred :( Second problem - stops to support the IE Application stopped to work in Internet Explorer. I tried two different machines (Windows XP and 7) with IE 8 and 10. Web page does not load at all (looks like the network problem, but the same URL works fine in Firefox). I confirmed the same problem with "Hello world" from the Opa tutorial compiled with both Opa stable 1.1.1 and build from sources. I suspected that the problem is due to Node.js update (Opa = 1.1.1 requires Node 0.10.* - now I am using 0.10.12, but I also tried other 0.10-s), but "Hello world" from the Node's from page works fine. I am running the app on OSX developer box and Linux Debian 7.0 server. Any suggestions what am I doing wrong? PS. I was off the business for a while. Anyone knows what happened to the Opa forum? Signing is seams not to work.

  • Website Live Chat Script - Interface With Windows Live Messenger?

    - by Sootah
    Hello again fellow StackOverflow users! What I am looking for currently is your opinions on the what the best live chat script would be for my website. I'd be using this on both my local computer repair (which I've not really set up yet) company's site, as well as my other technical support site that is geared more towards showing people how to fix whatever problem they have themselves. It'll be a little bit before I launch it on either site, as I need to find a good design for my local computer repair company's site, as well as redesign TweaksForGeeks.com's layout so that it's more magazine like. (If you have any suggestions on good Wordpress templates for these, that'd also be swell. :) ) Features I'd like for the live chat script to have: (if possible) Real-time posting of messages (or as close to real time as possible) Integration into my Windows Live Messenger account - By this I mean it'd be handy if instead of me having to man a separate open browser window and constantly check it for new messages, it'd be much more convenient if it would instead just allow me to receive and respond to messages via my Windows Live account the same way I'd chat with any other person on my contact list. Sound notification of new messages when the chat isn't the focused window - In the event that using Windows Messenger isn't possible then I'd need it to notify me upon receipt of a new message. Recording of chat transcripts - This is a MUST HAVE Easy customization - I'll likely want to modify how it looks and whatnot, in addition to the fact that I'm going to set it up so that the chat transcripts can be posted to my site easily in order to be useful to my other visitors later on. With all that in mind, what is available out there? I've not really researched this at all yet; aside from doing a cursory search just before I decided to ask my StackOverflow brothers. As always, thank you! -Sootah

  • Doubts in executable and relocatable object file

    - by bala1486
    Hello, I have written a simple Hello World program. #include <stdio.h> int main() { printf("Hello World"); return 0; } I wanted to understand how the relocatable object file and executable file look like. The object file corresponding to the main function is 0000000000000000 <main>: 0: 55 push %rbp 1: 48 89 e5 mov %rsp,%rbp 4: bf 00 00 00 00 mov $0x0,%edi 9: b8 00 00 00 00 mov $0x0,%eax e: e8 00 00 00 00 callq 13 <main+0x13> 13: b8 00 00 00 00 mov $0x0,%eax 18: c9 leaveq 19: c3 retq Here the function call for printf is callq 13. One thing i don't understand is why is it 13. That means call the function at adresss 13, right??. 13 has the next instruction, right?? Please explain me what does this mean?? The executable code corresponding to main is 00000000004004cc <main>: 4004cc: 55 push %rbp 4004cd: 48 89 e5 mov %rsp,%rbp 4004d0: bf dc 05 40 00 mov $0x4005dc,%edi 4004d5: b8 00 00 00 00 mov $0x0,%eax 4004da: e8 e1 fe ff ff callq 4003c0 <printf@plt> 4004df: b8 00 00 00 00 mov $0x0,%eax 4004e4: c9 leaveq 4004e5: c3 retq Here it is callq 4003c0. But the binary instruction is e8 e1 fe ff ff. There is nothing that corresponds to 4003c0. What is that i am getting wrong? Thanks. Bala

Or it depends // on your compiler vendor implementations? fun(get().c_str()); getchar(); } The output is : --> --> Hello World Hello, may I know the correct behavior is guarantee by C++ standard, or it depends on your compiler vendor implementations? I have tested this under VC2008 and VC6. Works fine for both.

  • Helpful advice on developing a professional MS Word add-on

    - by Dan Tao
    A few months back I put together a simple proof-of-concept piece of software for a small firm with an idea for a document editing tool. The company wanted this tool to be integrated into Microsoft Word, understandably, to maximize its accessibility to the average user. I essentially wrote the underlying library with all of the core functionality as a C# project, and then used VSTO to get it running inside of Word. It felt like a bit of a duct tape solution, really; but then, I have (practically) zero experience developing tools for integration with MS Office, and it was only a proof of concept anyway. Well, the firm was quite pleased with my work overall, and they're looking to move from "proof of concept" to the real deal. Fortunately, as I said, the core functionality is all there and will only need to be somewhat tweaked and enhanced. My main concern is figuring out how to put together an application that will integrate with MS Word in a clean and polished way, and which can be deployed easily in accordance with a regular user's expectations (i.e., simply running an install program and voila, it's there in Word). I seem to remember reading somewhere that nobody uses VSTO for real professional projects. Is this true? False? What are the alternatives? And what are the tips and gotchas that I should be aware of before getting started on this issue of MS Word integration?

  • Populating a foreign key table with variable user input

    - by Vincent
    I'm working on a website that will be based on user contributed data, submitted using a regular HTML form. To simplify my question, let's say that there will be two fields in the form: "User Name" and "Country" (this is just an example, not the actual site). There will be two tables in the database : "countries" and "users," with "users.country_id" being a foreign key to the "countries" table (one-to-many). The initial database will be empty. Users from all over the world will submit their names and the countries they live in and eventually the "countries" table will get filled out with all of the country names in the world. Since one country can have several alternative names, input like Chile, Chili, Chilli will generate 3 different records in the countries table, but in fact there is only one country. When I search for records from Chile, Chili and Chilli will not be included. So my question is - what would be the best way to deal with a situation like this, with conditions such that the initial database is empty, no other resources are available and everything is based on user input? How can I organize it in such way that Chile, Chili and Chilli would be treated as one country, with minimum manual interference. What are the best practices when it comes to normalizing user submitted data and is there a scientific term for this? I'm sure this is a common problem. Again, I used country names just to simplify my question, it can be anything that has possible different spellings.

  • Cross-Platform Camera API

    - by Karim
    Hi, I'm now building a video transforming filter that have to transform video frames in real-time. One of the key requirements of the filter is to have high performance to minimize the number of dropped frames during the transform. Another requirement that is of lower priority but also nice to have is to make it cross-platform (both PC's and Mobile devices). The application is built in C++. Now my question is: is there any API that is more portable and has a similar or better performance characteristics than DirectShow? as DirectShow's portability is only limited to Windows-based devices (PCs and Windows Mobile&CE platforms). Also I've notices that for example using HTC's custom camera API has far better performance than what DirectShow offers. If you want to check this, try to build a filter in DirectShow that will multiply each color by 2 and render that in real-time from camera on the screen. Then do the same with HTC's API. There is almost 4-5x performance boost with vendor's specific API. So it'd be very nice if the library used the device-specific implementation of the driver, as performance is critical when doing this transforms on a mobile device (which is about ~500 MHz).

  • PHP gettext on Windows

    - by Axsuul
    There's some tutorials out there for gettext (w/ Poedit)... unfortunately, it's mostly for a UNIX environment. And even more unfortunate is that I am running my WAMP server on Windows XP (but I am developing for a UNIX environment) and none of the tutorials can get gettext working properly for me. From the man page (http://us3.php.net/manual/en/book.gettext.php), it appears that it's a different process on a Windows environment. I've tried out some of the solutions in the comments but I still can't get it to work! Please, I've spent many hours on this, hopefully someone can point me in the right direction to get this thing to work! (and I'm sure there are others out there who share my frustration). So far with my setup, I'm only getting output "Hello World!" whereas I should be getting the translated string. Here is my setup/code so far: <?php // test.php if (!defined('LC_MESSAGES')) { define('LC_MESSAGES', 6); } $locale = "deu_DEU"; // apparently the locales are different on a WINDOWS platform putenv("LC_ALL=$locale"); setlocale(LC_ALL, $locale); bindtextdomain("greetings", ".\locale"); textdomain("greetings"); echo _("Hello World"); ?> Folder structure root: C:\Program Files\WampServer 2\www test.php: C:\Program Files\WampServer 2\www\site .po: C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.po .mo: C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.mo Please advise! Thanks for your time :)
