  • Imlpementations of an Interface with Different Types?

    - by b3njamin
    Searched as best I could but unfortunately I've learned nothing relevant; basically I'm trying to work around the following problem in C#... For example, I have three possible references (refA, refB, refC) and I need to load the correct one depending on a configuration option. So far however I can't see a way of doing it that doesn't require me to use the name of said referenced object all through the code (the referenced objects are provided, I can't change them). Hope the following code makes more sense: public ??? LoadedClass; public Init() { /* load the object, according to which version we need... */ if (Config.Version == "refA") { Namespace.refA LoadedClass = new refA(); } else if (Config.Version == "refB") { Namespace.refB LoadedClass = new refB(); } else if (Config.Version == "refC") { Namespace.refC LoadedClass = new refC(); } Run(); } private void Run(){ { LoadedClass.SomeProperty... LoadedClass.SomeMethod(){ etc... } } As you can see, I need the Loaded class to be public, so in my limited way I'm trying to change the type 'dynamically' as I load in which real class I want. Each of refA, refB and refC will implement the same properties and methods but with different names. Again, this is what I'm working with, not by my design. All that said, I tried to get my head around Interfaces (which sound like they're what I'm after) but I'm looking at them and seeing strict types - which makes sense to me, even if it's not useful to me. Any and all ideas and opinions are welcome and I'll clarify anything if necessary. Excuse any silly mistakes I've made in the terminology, I'm learning all this for the first time. I'm really enjoying working with an OOP language so far though - coming from PHP this stuff is blowing my mind :-)

  • Span with white-space style in IE (7) applied _past_ end of span

    - by WaldenL
    We've got an application where users can enter "notes" into a rich edit control (Telerik's RedEditor, but that doesn't matter here). We had a user enter notes from w/in Safari that had a <span></span> in the middle of the note, and that span had a style on it specifying white-space:pre The HTML of the note was in the form of: <div> This is a note <span class="Apple-tab-span" style="white-space: pre; "> </span> and here's more of the note. </div> Simple enough, the style should apply to the span, and the span had 4 spaces in it. There should have been 4 spaces in the resulting output. Here's the problem. IE seems to apply that white-space: pre; style not only to the span, but to the enclosing div! Therefore, this long line that should have wrapped since it's not in the span, now pushed the document out until the line fits on the page. What am I missing. I know IE has problems, but this doesn't seem right, even for IE. So, the question(s): 1) Am I correct that the white-space attribute should only have applied to the span? 2) Can this be resolved somehow? Remember, I'm not in control of the content being entered. And it's entered from a mac w/Safari and being viewed in IE. Edit: The doctype on the page in question is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  • Just 2 free months to learn or improve my skills

    - by microspino
    On the 30 of June I will leave my every day work to start as freelance developer. I'd like to set a period of 2 months apart to improve my dev skills. At work I code in C# and during my spare time I enjoyed building Ruby on Rails web applications and creating some Arduino prototypes. I'm something more than junior but I don't feel really a senior developer because I never had a big corporate project built and designed by me with help of other juniors (although I don't think this is really a good definiton of a "senior", It helps describing my feelings). Using a scale from 0 (ignorant) to 10 (proficient like a "samurai") the list below describes my skills that I would like to improve with just 2 months. I've already bought some nice and updated books on all the subjects hereunder: The order doesn't matter C = 1 C# & .Net = 6 Arduino & Processing = 2 Ruby = 5 Rails = 5 HTML/XHTML/CSS = 9 Javascript = 6 Objective-C/iPhone dev = 2 Python = 4 Django = 4 Desing Patterns = 3 Algorythms = 3 Git = 5 I haven't included SQL or Databases in general nor Networking because I spent 10 years working in the past with them and I feel pretty solid for now. As an aside, I've made up some interest in Redis, Node.js, HTML5 reading about them on the web. After two months, since I have to pay my bills, I could go searching for some new job. If learning and developing were really good maybe I could also invest on something I gave birth during them. Can You give me some piece of advice on which you think It's better to improve or develop a learning project on (something like a "summer of code" thing)? The all point Is to see my weaknesses and work on them.

  • Generics in return types of static methods and inheritance

    - by Axel
    Generics in return types of static methods do not seem to get along well with inheritance. Please take a look at the following code: class ClassInfo<C> { public ClassInfo(Class<C> clazz) { this(clazz,null); } public ClassInfo(Class<C> clazz, ClassInfo<? super C> superClassInfo) { } } class A { public static ClassInfo<A> getClassInfo() { return new ClassInfo<A>(A.class); } } class B extends A { // Error: The return type is incompatible with A.getClassInfo() public static ClassInfo<B> getClassInfo() { return new ClassInfo<B>(B.class, A.getClassInfo()); } } I tried to circumvent this by changing the return type for A.getClassInfo(), and now the error pops up at another location: class ClassInfo<C> { public ClassInfo(Class<C> clazz) { this(clazz,null); } public ClassInfo(Class<C> clazz, ClassInfo<? super C> superClassInfo) { } } class A { public static ClassInfo<? extends A> getClassInfo() { return new ClassInfo<A>(A.class); } } class B extends A { public static ClassInfo<? extends B> getClassInfo() { // Error: The constructor ClassInfo<B>(Class<B>, ClassInfo<capture#1-of ? extends A>) is undefined return new ClassInfo<B>(B.class, A.getClassInfo()); } } What is the reason for this strict checking on static methods? And how can I get along? Changing the method name seems awkward.

    The following code is a very simple ajax call to server that alerts back on success and complete events. From a reason I cannot understand on my development machine it works fins and alerts on success and complete but on server it never alerts on success. WHY ??? ** <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script src="Scripts/jquery-1.7.1.min.js" type="text/javascript"></script> <script type="text/javascript"> function dummy() { $.ajax({ url: 'services/chatEngine.asmx/dummy', async: true, type: "POST", complete: function () { alert('Done'); }, success: function (a, b, c) { alert('Success'); } }); } </script> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </ajaxToolkit:ToolkitScriptManager> <div id="userList">Users:<br /></div> <input id="Button3" type="button" value="dummy" onclick="dummy()" /> </div> </form> </body> </html> ** The server side dummy function returns nothing, code follows - Public Function dummy() As String Return "" End Function

  • Cross Platform C library for GUI Apps?

    - by Moshe
    Free of charge, simple to learn/use, Cross Platform C library for GUI Apps? Am I looking for Qt? Bonus question: Can I develop with the said library/toolkit on Mac then recompile on PC/Linux? Super Bonus Question: Link to tutorial and/or download of said library. (RE)EDIT: The truth is that I'm in the process of catching up on the C family (coming from web development - XHTML/PHP/MySQL) to learn iPhone development. I do understand that C is not C++ or ObjectiveC but I want to keep the learning curve as simple as possible. Not to get too off topic, but I am also on the lookout for good starter books and websites. I've found this so far. I'm trying to kill many birds with one stone here. I don understand that there are platform specific extensions, but I will try to avoid those for porting purposes The idea is that I want to write the code on one machine and just compile thrice. (Mac/Win/Linux) If Objective C will compile on Windows and Linux as well as OS X then that's good. If I must use C++, that's also fine. EDIT: Link to QT Please...

    - by Darxval
    So i am trying to call this function in my javascript but it gives me the error of "Microsoft JScript runtime error Object doesn't support this property or method" and i cant figure out why. It is occuring when trying to call hmacObj.getHMAC. This is from the jsSHA website: http://jssha.sourceforge.net/ to use the hmac-sha1 algorithm encryption. Thank you! hmacObj = new jsSHA(signature_base_string,"HEX"); signature = hmacObj.getHMAC("hgkghk","HEX","SHA-1","HEX"); Above this i have copied the code from sha.js snippet: function jsSHA(srcString, inputFormat) { /* * Configurable variables.

  • Java EE 6: JSF vs Servlet + JSP. Should I bother learning JSF?

    - by Harry Pham
    I am trying to get familiar with Java EE 6 by reading http://java.sun.com/javaee/6/docs/tutorial/doc/gexaf.html. I am a bit confused about the use of JSF. Usually, the way I develop my Web App would be, Servlet would act like a controller and JSP would act like a View in an MVC model. So Does JSF try to replace this structure? Below are the quote from the above tutorial: Servlet are best suited for service-oriented App and control function of presentation-oriented App like dispatching request JSF and Facelet are more appropriated for generating mark-up like XHTML, and generally used for presentation-oriented App Not sure if I understand the above quote too well, they did not explain too well what is service-oriented vs presentation-oriented. A JavaServer Faces application can map HTTP requests to component-specific event handling and manage components as stateful objects on the server. Any knowledgeable Java developer out there can give me a quick overview about JSF, JSP and Servlet? Do I integrate them all, or do I use them separated base on the App? if so then what kind of app use JSF in contrast with Servlet and JSP A JavaServer Faces application can map HTTP requests to component-specific event handling and manage components as stateful objects on the server. Sound like what servlet can do, but not sure about manage components as stateful objects on the server. Not even sure what that mean? Thanks in advance.

  • CSS horizontal scrolling overflow with jQuery slider

    I'm trying to setup a full screen jquery slider. I've broken the project into two steps 1) css and 2) js. 1) CSS, below is a picture of what I'm shooting for (no fixed height) and below that is the code I have so far that doesn't work. <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style type="text/css"> /* Positioning */ #container { width: 2500px; } .block { display: inline; } /* Styling */ .block img { padding: 5px; } </style> </head> <body> <div id="container"> <div class="block"><img src="http://i42.tinypic.com/1zp2poz.gif"></div> <div class="block"><img src="http://i42.tinypic.com/1zp2poz.gif"></div> <div class="block"><img src="http://i42.tinypic.com/1zp2poz.gif"></div> </div> </body> </html> 2) Javascript, using jquery I'd like the divs to slide left when clicked on them... like the jQuery Coda Slider if possible.

  • SimpleTest assertTags - loose matching? (for CakePHP)

    - by Arkaaito
    I'd like to use SimpleTest to set up some functionality tests for our project - in particular, we have a very busy page which has some random components and some static components, and I'd like to be able to write a simple test which only confirms the static bits (preferably only the one or two most important ones). In other words, I want to be able to leave out any tags on the page I don't care about, and write something like: $result = "<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head><title>...</title><meta .../></head><body><script type="text/javascript">...</script><div class="center-splash"><span>Welcome JohnDoe</span><p>Your progress:</p>...</div><div class="left-column">...</div><div class="right-column">...</div>...</body></html>"; $expects = array('html'=>true,'body'=>true,'div'=>array('class'=>'center_splash'),'span'=>true,'Welcome JohnDoe','/span','/div','/body','/html'); $this->assertTagsButIgnoreExtras($result, $expects); When I try this with assertTags it fails. Is there a version of assertTags which allows this - something either officially part of the SimpleTest or CakePHP project or unofficially put out under the MIT license or similar?

  • Is there a free, smale-scale, not web-based issue/bug tracking system?

    - by Doc Brown
    I know, there were posts before here on SO before concerning issue or bug tracking systems, like this one, but the given answers point either to commercial systems or web-based systems, which both seem to be oversized for our needs. What I am looking for is a non-commercial tool for a team of 3 to 4 developers, which can be used on an existing fileserver, without the need of installing additional server software like a C/S database or a web server. Some things I expect from such a system: allows to remember bugs (with a priority) and issues / ideas for new features (mostly without a priority) description of the issue, perhaps some additional remarks short info who entered the bug/issue entry one or more tags allowing us to group or filter the list Any suggestions? EDIT: I should have said that, but we are using MS Windows clients, Visual Studio development, Tortoise SVN (the latter works fine without a subversion server). And yes, I am strict on "no server software", since all server based solutions I have seen so far seem much to oversized/heavy weighted/too-much-effort-to-be-worth-it. In fact, if no one has a better idea, we are going to use a spreadsheet, but I can't believe there are no ready-made, light weight solutions.

  • Strange thread behavior in Perl

    - by Zaid
    Tom Christiansen's example code (à la perlthrtut) is a recursive, threaded implementation of finding and printing all prime numbers between 3 and 1000. Below is a mildly adapted version of the script #!/usr/bin/perl # adapted from prime-pthread, courtesy of Tom Christiansen use strict; use warnings; use threads; use Thread::Queue; sub check_prime { my ($upstream,$cur_prime) = @_; my $child; my $downstream = Thread::Queue->new; while (my $num = $upstream->dequeue) { next unless ($num % $cur_prime); if ($child) { $downstream->enqueue($num); } else { $child = threads->create(\&check_prime, $downstream, $num); if ($child) { print "This is thread ",$child->tid,". Found prime: $num\n"; } else { warn "Sorry. Ran out of threads.\n"; last; } } } if ($child) { $downstream->enqueue(undef); $child->join; } } my $stream = Thread::Queue->new(3..shift,undef); check_prime($stream,2); When run on my machine (under ActiveState & Win32), the code was capable of spawning only 118 threads (last prime number found: 653) before terminating with a 'Sorry. Ran out of threads' warning. In trying to figure out why I was limited to the number of threads I could create, I replaced the use threads; line with use threads (stack_size => 1);. The resultant code happily dealt with churning out 2000+ threads. Can anyone explain this behavior?

  • How to start matching and saving matched from exact point in a text

    - by yuliya
    I have a text and I write a parser for it using regular expressions and perl. I can match what I need with two empty lines (I use regexp), because there is a pattern that allows recognize blocks of text after two empty lines. But the problem is that the whole text has Introduction part and some text in the end I do not need. Here is a code which matches text when it finds two empty lines #!/usr/bin/perl use strict; use warnings; my $file = 'first'; open(my $fh, '<', $file); my $empty = 0; my $block_num = 1; open(OUT, '>', $block_num . '.txt'); while (my $line = <$fh>) { chomp ($line); if ($line =~ /^\s*$/) { $empty++; } elsif ($empty == 2) { close(OUT); open(OUT, '>', ++$block_num . '.txt'); $empty = 0; } else { $empty = 0;} print OUT "$line\n"; } close(OUT); This is example of the text I need (it's really small :)) this is file example I think that I need to iterate over the text till the moment it will find the word LOREM IPSUM with regexps this kind "/^LOREM IPSUM/", because it is the point from which needed text starts(and save the text in one file when i reach the word). And I need to finish iterating over the text when INDEX word is fount or save the text in separate file. How could I implement it. Should I use next function to proceed with lines or what?

  • Colorbox iFrame content not appearing in IE 8/9

    - by Rocketpig
    I'm using ColorBox to call a few informational modals on-screen and given the client's requirements, the best way to do this is via iFrames (not my first choice but whatever). Everything is working peachy in Chrome, FF, etc. but the iFrame content is not working in any version of IE. The modal wrapper appears but nothing is inside. This is what I've done so far: Changed the doctype to transitional and strict for IE. No dice. Removed the "iframe: true" and replaced it with HTML "Hello". That worked fine and "Hello" appeared in the Colorbox modal. I've removed all stylesheets from the header. No luck so it's not a CSS issue. Just to be sure, I rolled back my JQuery library to 1.6.2 from 1.8.2. Nothing there, either. Any help would be appreciated. This is aggravating. Some code: $(function () { $(".modal-large").colorbox({iframe:true, innerWidth:580, innerHeight:500}); }) HTML: <div class="top-droptext"><a class="modal-large" href="modal/serviceproviderinfo.html">Update Password</a></div>

  • Why doesn't String's hashCode() cache 0?

    - by polygenelubricants
    I noticed in the Java 6 source code for String that hashCode only caches values other than 0. The difference in performance is exhibited by the following snippet: public class Main{ static void test(String s) { long start = System.currentTimeMillis(); for (int i = 0; i < 10000000; i++) { s.hashCode(); } System.out.format("Took %d ms.%n", System.currentTimeMillis() - start); } public static void main(String[] args) { String z = "Allocator redistricts; strict allocator redistricts strictly."; test(z); test(z.toUpperCase()); } } Running this in ideone.com gives the following output: Took 1470 ms. Took 58 ms. So my questions are: Why doesn't String's hashCode() cache 0? What is the probability that a Java string hashes to 0? What's the best way to avoid the performance penalty of recomputing the hash value every time for strings that hash to 0? Is this the best-practice way of caching values? (i.e. cache all except one?) For your amusement, each line here is a string that hash to 0: pollinating sandboxes amusement & hemophilias schoolworks = perversive electrolysissweeteners.net constitutionalunstableness.net grinnerslaphappier.org BLEACHINGFEMININELY.NET WWW.BUMRACEGOERS.ORG WWW.RACCOONPRUDENTIALS.NET Microcomputers: the unredeemed lollipop...

  • How can I read a continuously updating log file in Perl?

    - by Octopus
    I have a application generating logs in every 5 sec. The logs are in below format. 11:13:49.250,interface,0,RX,0 11:13:49.250,interface,0,TX,0 11:13:49.250,interface,1,close,0 11:13:49.250,interface,4,error,593 11:13:49.250,interface,4,idle,2994215 and so on for other interfaces... I am working to convert these into below CSV format: Time,interface.RX,interface.TX,interface.close.... 11:13:49,0,0,0,.... Simple as of now but the problem is, I have to get the data in CSV format online, i.e as soon the log file updated the CSV should also be updated. What I have tried to read the output and make the header is: #!/usr/bin/perl -w use strict; use File::Tail; my $head=["Time"]; my $pos={}; my $last_pos=0; my $current_event=[]; my $events=[]; my $file = shift; $file = File::Tail->new($file); while(defined($_=$file->read)) { next if $_ =~ some filters; my ($time,$interface,$count,$eve,$value) = split /[,\n]/, $_; my $key = $interface.".".$eve; if (not defined $pos->{$eve_key}) { $last_pos+=1; $pos->{$eve_key}=$last_pos; push @$head,$eve; } print join(",", @$head) . "\n"; } Is there any way to do this using Perl?

  • Change css property in chain - JavaScript

    - by SilverDeveloper
    I'm using MooTools 1.4.5 and I want to change cursor before calling function that takes some time and after finished same function set cursor to default. I was not successful. After that I made simple example to change background color via plain JavaScript (no jQuery or MooTools plugin) and again I was not successful. Here is my code. <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> </div> </form> </body> <script type="text/javascript"> <!-- document.body.style.background = 'red'; setTimeout(function () { }, 1250); document.body.style.background = 'yellow'; //--> </script> </html> First at all I set background color to red, and after delay to yellow. I assumed that the background color will bi set to red and after delay to yellow. It doesn't work. When page is loaded background color is yellow (last line). If I insert alert function in a middle of lines where sets background color everything works fine (background color is red, click to message box, background color is yellow). Why it works so? Only last changing style is affected. I need something like that to change pointer before calling function that takes 10 seconds and setting cursor to default value after function is done.

  • Run Jmol applet using apache server

    - by user1144004
    I am a newbie in using apache and jmol. I am trying to run a jmol applet in python using apache server. Because of strict folder arrangement restrictions in jmol (html and model files should be present inside jmol folder), I had to move the default htdocs and cgi-bin folder inside jmol folder by editing the "httd.conf" file. Now the new location of htdocs folder is "Apache2.2/jmol/htdocs" and of cgi-bin folder is "Apache2.2/jmol/cgi-bin". Now I've put my "start.html" file in the htdocs folder which has the jmol applet tag. It takes "CA150.XYZ" file which is also placed in the same folder. On running this "start.html" file through apache server, nothing happens. It even doesn't give any error, it just shows a blank page. But if I try to run "start.html" without apache server, jmol applet do get executed and runs successfully. What am I doing wrong? Any idea? Here is my "start.html" file <head> <title>Simple example</title> <script src="../Jmol.js" type="text/javascript"></script> </head> <body> <form> <script type="text/javascript"> jmolInitialize("../"); jmolApplet(200,"load CA150.XYZ"); </script> </form> </body>

  • android use local service to refresh map UI

    - by urobo
    I don't need a strict code related answer I just need somebody to tell me what I am missing. My application has to retrieve from a web service (xmlrpc) the positions of some users I know and update their position on a MapView. So I decided to use a Service and an Activity extending MapActivity to show results. I thought about two solutions: I ) start the service and make it ask every minute for these positions and send them to the activity as a bundle via intent. (This didn't work out well, since once shown I couldn't find a method to let the activity continue refresh itself until she stop receiving intents+data from the service) II ) Incorporate a thread within the activity which starts the service via context.startService(...) every minute. And the MapUI refresh itself once the service send back an intent and stop itself. (Maybe I will fall in the same problem category as before I haven't tryied yet). I am also giving directions (via maps.google ws) in this way I'd like to refresh only users positions on the map and save the route. What Am I missing do you have any suggestions? related to activities/services internal mechanics, don't know launch modes, use broadcast receivers or intent filters? Thanks in advance
